Hoshizaki recommends that the ice machine drain andbin drain be piped separately to the drain connection pointallowing 1/4" per foot fall.
CONDENSATE DRAIN -
The condensate drain is generally connected to the icemachine drain for simplicity. It can be piped separately tothe drain exit if desired.
A 6" vent tee is recommended as per drawing:
FLOW RATES -
The minimum flow rate requirements for Hoshizaki icemaker units are as follows:
KM-150/250/280/AII Flakers 1.05 GPMKM-500 1.58 GPMKM-630/900/AII DCM's 2.11 GPMKM-1300/1600 3.96 GPMKM-2000/2400 4.23 GPM
Use this information when sizing a filter system for the icemachine application.
NOTE: A good rule of thumb is to utilize a 3 GPM flow ratefilter for KM-150 through 900 and a 5 GPM flow rate filterfor KM-1300 or larger.

Note:All Electrical connections must be made in accordancewith all national and local electrical codes.
Transformer ApplicationAll 208-230V models include a 115V transformer with a208/230V selector switch. Be sure to select the positionthat best matches the incoming voltage prior to supplyingpower to the unit. (Voltage from the center tap to caseground will be 67.5V due to the transformer circuit.)
208/230V models include 115V controls. They require a115 / 208-230V circuit which has 4 wires including L1, L2,dedicated neutral, and ground.
If a dedicated neutral is not available or the previous unitused a 3 wire circuit, (L1,L2, & gnd.) a step-down trans-former can be used at the unit to provide power to the115V components. This will save on installation time andcost if a dedicated neutral is not present.
Transformer # 4A0817-01 or equivalent can be used forKM models. Transformer # 446240-01 or equivalent canbe used for F-1000 models. The transformer should bemounted inside the compressor compartment and wiredusing the following generic diagram.

LINE SET INSTALLATIONA universal line set adapter kit, part number OS-QUICK, isavailable if you need to field engineer your line set. Bothlines should be insulated separately the entire length of run.
The refrigerant charge for a new unit is distributed betweenthe unit head and the URC condenser. The line set has aminimal holding charge of 15 to 30 psig refrigerant vapor.
If you need to field engineer your line set or shorten/lengthen a precharged line set you can do so by followingthese steps:
1. Using the OS-QUICK kit, braze the line set connec-tions. (If you shorten or lengthen a precharged lineset, recover the holding charge, cut or lengthen andbraze the connections.)
2. Pressurize the lines and leak check all braze joints.
3. Evacuate the lines through the service ports on theAeroquip quick connect fittings.
4. Charge both lines with 15 to 30 psig R-404A vapor.
To make Aeroquip connection to the unit head andcondenser:
1. Lubricate the threads and O-ring with cleanrefrigerant oil.
2. Tighten the female connector until it bottoms out.
Note: Always use a back up wrench when tighteningthese fittings.
3. Then turn an additional 1/4 turn to assure a goodbrass to brass seal. Leak check the joints with soapbubbles or an electronic leak detector.

SYSTEM CHARGE - R-404AThe ice machine head and URC condenser are shippedwith enough refrigerant charge for up to 66 feet of line setlength. The maximum line set length is 100 equivalent feetfrom the head to the condenser.
For applications longer than 66 ft. up to the maximum 100 ft.Length, additional refrigerant must be added. For units uti-lizing 1/4" L.L. and 3/8" D.L., the line size should be in-creased to 3/8"L.L. and 1/2"D.L. for the entire length of therun. Add 16.5 ounces plus 0.4 oz. per foot over 66 feet. Forunits utilizing 3/8"L.L., add 0,4 oz. per foot over 66 feet.
NOTE:(1) Recommended line sizes are same as listed in
the line set application chart.(2) Older models utilize R-502 refrigerant or R-22
refrigerant. Always check the unit nameplate forthe correct refrigerant type.Do not connect components using different typerefrigerants!
(3) If refrigerant is added due to extended line setlength, mark the correct total charge on the unitnameplate for future reference.
(4) When routing and installing remote lines, alwaysuse standard refrigerant piping practices.
(5) Hoshizaki recommends eliminating any excessloops in a pre-charged line set application beforemaking the unit connections. This will eliminate oiltraps and possible crimps in the excess tubing.
(6) A service loop should be included behind the unit as shown in the illustration on page 13 to allow the unit to be moved away from the wall if needed.
CRITICAL CHARGE AMOUNTThe total system charge is critical for proper operationaccording to Hoshizaki specification. Always weigh in theproper charge per the following charge chart. (Remoteunits show standard charge good for up to 66 feet.) Unitcharge information is also found on the unit Name Plate.

Note: F series condensers are used for both F and Hseries remote units.
REFRIGERANT OILAll R-404A models use Polyol Ester (POE-EAL) oil. POE oilabsorbs moisture easily. Extra care must be taken to re-duce the possibility of moisture entering the system duringservice. If moisture contamination is suspected, the oilshould be changed and the liquid line drier must be re-placed. Changing the oil requires removal of the compres-sor so that the oil can be drained and replaced with thecorrect amount. See compressor data chart for oil amount.Replacement compressors are shipped with POE oil.

provide for longer flush and switches 5&6 to every cyclepump-out 1/1. Do not adjust 1&2 on KM150/250 in highambient area.
2. DO NOT ADJUST 3, 4, 7, 8, 9 &10 from factory setting.3. DO NOT MAKE CONNECTION to the red K-4 terminal
unless a special bin control / red connector is provided.4. Dip-switches 9&10 are on improved “E” board only. If
original board has 8 dip-swithes, use default setting ofOFF/OFF for 9 & 10. If original board has 10 dip-switches,match original “E” board settings.

SETTING CHART FOR R-404A (F/H) MODELS
Note: The above chart reflects the factory dip-switch set-tings for models using R-404A refrigerant. Adjustmentsmay be made to switches 1, 2, 5, & 6 to improve the built-incleaning ability as per the DIP SWITCH SETTING GUIDE. Ifyou replace the control board, match the cleaning settingswith the original board. Switches 3, 4, 7, 8, 9, & 10 mustremain in the factory position.

“E” Control Board FunctionsAn instruction label explaining the “E” board features is in-cluded somewhere on the unit. You should find it either onthe control box cover, on the inside of the front panel, orunder the top panel. A stick on label is also included with theservice replacement board. If you are replacing an “E” board,be sure to place the new label over the original label. Thiswill advise anyone performing future service that the origi-nal board has been replaced and explain the applicationswitch as outlined below.
The #2A1410-02 universal replacement board has an appli-cation switch between relays X3 & X4 that is not included onthe original factory board supplied with the unit. This applica-tion switch allows this replacement board to be used on olderC and Alpine control board models. The application switchhas 2 positions (C & ALP). On R-404A models, this switchmust be in the ALP position. If the switch is left in the Cposition, the compressor contactor will energize as soon aspower is supplied to the unit whether the power switch is ONor OFF.
There are 4 green LED’s which light in sequence throughoutthe unit operation. It is important to note that the green LED’sare not numbered consecutively. LED1 is located at the edgeof the board beside the K-2 transformer connection. The num-bering sequence from the outside edge of the board is 1, 4, 3,and 2.
The green LED’s are also used for a built-in output test whichcan be conducted to diagnose a bad board. The label ex-plains the output test procedure. The correct lighting sequencefor the output test is as follows. When the control switch isswitched ON with the output test switch S-3 ON, after a 5second delay, LED2 lights. 5 seconds later LED2 goes outand LED3 lights. 5 seconds later LED3 goes out and LED4lights. 5 seconds later LED4 goes out and LED1 lights. 5seconds later LED1 goes out and LED4 lights to begin thenormal sequence of operation. If the LED’s follow this se-quence, the board is OK. If any other lighting sequence oc-curs, the board is bad.
A copy of the “E” board label is included on the next page.Review the board label thoroughly to understand the “E” boardfunctions.

ATTENTION !THIS UNIT HAS A CONTROL PRODUCTS IMPROVED “E” CONTROLBOARD INSTALLED. HOSHIZAKI PART NUMBER 2A1410-01.The improved “E” board includes LED lights and audible alarm safeties. The red LED indicates proper control voltage and will remain on unless a controlvoltage problem occurs. At startup a 5 second delay occurs while the boardconducts an internal timer check. A short beep occurs when the powerswitch is turned “ON” or “OFF”.
The green LED’s 1~4 represent the corresponding relays and energize andsequence 5 seconds from initial startup as follows:
Sequence Step LED’s on: Length:Min. Max. Avg. 1 Minute Fill Cycle LED 4 60 sec. Harvest Cycle LED 1, 4, & 2 2 min. 20 min. 3-5 min. Freeze Cycle LED 1 5 min. 60 min. 30-35 min. Reverse Pump Out LED 1, 3, & 2 10 sec. 20 sec. Factory set. {With light on, LED 1 = Comp/RFM; LED 2 = HGV; LED 3 = PM; LED 4 = WV} Note: LED’s are not numbered consecutively. They are # 1,4,3,2 from board edge.
The built in safeties shut down the unit and have alarms as follows: 1 beep every 3 sec. = High Evaporator Temperature >127° F.
Check for defrost problem (stuck HGV or relay), hot water enteringunit, stuck headmaster, or shorted thermistor.
2 beeps every 3 sec. = Defrost Back Up Timer. Defrost >20 minutes.Orange LED marked “H Timer” energizes. Check for openthermistor, HGV not opening, TXV leaking by, low charge, orinefficient compressor.
3 beeps every 3 sec. = Freeze Back Up Timer. Freeze > Specified SettingYellow LED marked “F Timer” energizes. Check for F/S stuckclosed (up), WV leaking by, HGV leaking by, PM not pumping, TXVnot feeding properly, low charge, or inefficient comp. Dip switches 9& 10 allow for factory adjustment of this back up timer feature.
Note: 2 & 3 beep alarms represent 2 consecutive occurrences.
Additional alarms for mechanical bin switch: 4 beeps every 3 sec. = Short Circuit between the K4 connection on the
control board and the bin control. Check connections and replace wire harness if necessary.
5 beeps every 3 sec. = Open Circuit between the K4 connection on thecontrol board and the bin control. Check connections and replacewire harness if necessary.
Note: Units with mechanical bin switch installed, dip switch No.7 must be in the “ON” position. If thermostatic control is used No. 7 must be “OFF”.
To manually reset the above safeties, depress white alarm reset button with the power supply “ON”.
6 beeps every 3 sec. = Low Voltage. Control voltage < 92 Vac ±5%. The red LED will de-energize if voltage protection operates. 7 beeps every 3 sec. = High Voltage. Control voltage > 147 Vac ±5%.
The red LED will de-energize if voltage protection operates. Note: The voltage safety automatically resets when voltage is corrected.
The Output Test switch “S3” provides a relay sequence test. With powerOFF, place S3 on and switch power to ICE. The correct lighting sequence should be none, 2, 3, 4, 1, & 4, in 5 second intervals, then normal sequence.Components will cycle during test. S3 should remain in the “OFF” position for normal operation.
The dip switches should be adjusted per the adjustment chart published in the Tech Specs book. No. 8 must remain in the “OFF” position.

MANUAL RESET SAFETIES:The Alpine control board has one manual reset safety. It isthe 127°F high evaporator temperature safety. There is noindication that the Alpine board is off on this safety. Youwill only notice that the unit will restart in the 1 minute fillcycle when the power switch is shut OFF and Back ON.This is the only way to reset this safety. If this occurscheck for a hot gas circuit or valve problem, a headmasterstuck in bypass, hot water entering the unit, or a shortedthermistor. In case of a shorted thermistor, the unit will notrestart. You will hear a relay click after approximately 2seconds and the unit will remain off.
The “E” control board can have up to 5 manual reset safe-ties. They are outlined in the control board function label.These safeties shut the unit down and assist the servicetechnician in diagnosing the problem.The safeties include audible and visual alarms as follows:1 Beep = 127ºF (52.8ºC) high evaporator temp. safety.2 Beeps & orange LED = 2 consecutive 20 minute harvestcycles.3 Beeps & yellow LED = 2 consecutive maximum freezecycles.4 Beeps = Short circuit on mechanical bin control circuit.5 Beeps = Open circuit on mechanical bin control circuit.
To reset either safety, press the white reset buttonon the control board with the power ON. Next, pro-ceed to check the items outlined on the function label.
The items listed on the function label represent the mostcommon reasons that the safety would function. Theremay be other remote possibilities however, the items listedshould be checked first.
VOLTAGE PROTECTION:Built-in voltage protection for the “E” board will automati-cally shut the unit down and beep if either a high or lowvoltage problem occurs as follows:6 Beeps = Low voltage condition.7 Beeps = High voltage condition.
The high and low voltage protections are the only boardalarms that will automatically restart the unit when the volt-age returns to normal. If constant voltage fluctuation oc-curs, additional external voltage protection will be required.

PENN VALVE
HEAD PRESSURE CONTROLS
WATER-COOLEDAn adjustable (Pressure Modulated) water-regulating valveis installed on the water-cooled condenser outlet. A # V46Johnson Controls Penn valve is used. A label on the valvehousing identifies the Penn valve.
Adjust:CW - for lower pressure and outlet water temperature withhigher water flow.CCW – for higher pressure and outlet water pressurewith lower water flow.
CONDENSER OUTLET WATER TEMPERATURE RANGE.
Model Range High side pressureAll KM 104 ~ 115 ºF 270 psig.All DCM 100 ~ 104 ºF 260 psig.All F 100 ~ 104 ºF 260 psig.
In some cases, if the water-cooled unit has been in opera-tion for a long period of time, adjusting the water- regulatingvalve does not allow proper pressures. In this case the wa-ter-cooled condenser is likely scaled and requires cleaning.An acid based condenser cleaner should be circulated throughthe coil using an acid pump, until the inner tube is free ofscale. Once the scale is removed, the water-regulating valveshould be adjusted to maintain the range and pressure listedabove.

REMOTE HEAD PRESSURE CONTROLAll remote condenser units utilize a condensing pressure regu-lating (CPR/Headmaster) valve to maintain head pressure inlow ambient conditions. You will find a Sporland LAC-4 210psig. valve mounted in the condenser of all R-404A remoteunits with the exception of the KM-2400SRF3. The KM-2400SRF3 model uses a Sporland LAC-5 210 psig valvewhich is mounted in the unit head.
The symptoms of a bad headmaster are similar to an under-charged unit. To diagnose a bad headmaster, add additionalrefrigerant in 2 lb. increments and watch the pressures. Ifthe pressures begin to look normal, the unit was undercharged.In this case, leak check the system to find the leak and usenormal refrigeration practices to recover, repair, evacuate andrecharge the unit. If not, a bad headmaster is a possibility.Check to see if the valve is stuck open by conducting tem-perature checks at the outlet of the headmaster. Replace theheadmaster as necessary. Use safe refrigeration practiceswhen removing the valve and protect the valve from over-heating.

BIN CONTROLKM BIN CONTROLS:KM/KML cubers will use one of three types of bin controls.The type of bin control will vary depending on the unit style,or model and serial number.
1. THERMOSTATIC BIN CONTROL:The thermostatic bin control is the primary control that sup-plies 115 volts to all major components in the unit except thecompressor. When this control is closed, 115V is suppliedto the control transformer and to the K1 control boardconnector which switches 115 volts to the components asthe sequence dictates. A thermostatic capillary bulb ismounted in the ice drop zone area or on a drop downbracket which extends into the bin cavity.
The Thermostatic control is normally closed. (It opens ontemperature drop and closes on temperature rise.) Whenice touches the thermostatic bulb, the bulb pressure opensthe bin control switch to shut the unit down. The thermo-static bin control will shut the unit down at any point in thesequence of operation if ice contacts the control bulb. Theshut down time will depend on the control adjustment. Thisadjustment is factory set however it should always bechecked at start-up to assure proper operation. Highaltitude areas require adjustment. When ice is movedaway from the bulb, the unit will always restart in the 1-minute fill cycle.
Note: The unit will not operate in either ICE or WASH un-less the thermostatic bin control switch is closed.
Larger M models and S models include a drop down bulbbracket. This bracket should be secured to the unit baseand the control plug connection must be made beforethe unit will operate. A bin control extension bracket isincluded with all S models. Be sure to install the extension

12/01/02
When replacing a thermostatic bin control, check the op-eration by holding ice against the thermostatic bulb with thecontrol switch in the wash position. The pump should stopwithin 6 to 10 seconds. Adjustment up to 30~45 secondscould be acceptable depending on the application. Adjustthe control “CCW” for a faster shut down.
Note: Control board dip switch number 7 must be OFF forthis control to operate the unit. A thermostatic bin controlmay be used on KML models and is required for somedispenser application.
2.MECHANICAL BIN CONTROL:KML and some M models use a mechanical bin control.This control includes a proximity switch and actuator paddleassembly. The mechanical bin control assembly mounts inthe ice drop zone area and will shut the unit dowm within 3seconds when ice pushes the actuator paddle to the fullright position, away from the proximity switch. Shut downwill only occur during the first 5 minutes of the freeze cyclewhen the paddle is moved away from the proximity switch.If the paddle is moved away from the proximity switch andheld at any other time during the sequence, the unit willcontinue to run until the next freeze cycle occurs. Thisfeature allows for a full batch of ice every cycle so thatthere are no small cubes in the bin.
A resistor wireing harness connects the mechanical bincontrol to the red K4 connector on the control board. As theproximity switch opens and closes, the resistance valuewill change to either start up or shut down the unit.

b) When the unit is held to the right, the resistance at theK4 red connector will be 15.8 K ohms and the unit will shutdown within 3 seconds during the first 5 minutes of thefreeze cycle or at the beginning of the next freeze cycle atany other time in the sequence of operation.
Mechanical control in the normal position supplies 7.9 Kohms at red K4 connector to start unit.
Mechanical bin control in the full right position supplies15.8 K ohms at connector red K4 to shut unit down.
Note: Control board dip switch number 7 must be ON forthis control to operate the unit.
3. CAPACATIVE PROXIMITY SWITCH: KM-1300NRFThis control is used only on the KM-1300NRF model whichwas designed tor 42 inch beverage dispenser applica-tions. You will find it only on this specific model. The controlworks by sencing mass (in this case, ice) within 1/2 to 1

F/DCM Bin ControlFlaker / DCM units use a mechanical bin control. A paddlepivots on a hinge pin to operate either a micro- switch ormagnetic proximity switch. For proper operation, make surethat the paddle swings freely. The F-450MAF-C cubeletunit uses an Infrared eye control since it is designed fordispenser applications. This control has a seperate DCpower supply and an infrared sensor which is mountedto the base of the ice chute.
CAPACITORSSee wiring diagram reference chart for capacitor ratings.Check capacitors with an ohm meter for a short or opencircuit. A capacitor checker can be used to check thecapacitance however, it is a good common practice tochange a run capacator any time a PSC motor is replaced.Always check the run capacitor if a PSC motor will notstart, is running slow, overamping, or overheating.
inch of the sensor. It also connects to the K4 red connec-tor on the control board and has the same operating se-quence as the mechanicam bin control.
The capacitive proximity control has 4 components includ-ing a sensor, bin control relay, 24VDC power supply andresistor harness. This resistor harness is slightly differentfrom the harness used for the mechanical control. It willsupply either 15.8 K ohms or 5.6 K ohms to the red K4connector to control the unit.
As the sensor switches, the resistance value will changeto either start up or shut down the unit through the controlboard K4 connector.a) When no ice is present within 1/2~1 inch of the sensorend, the resistance at the K4 connector will be 5.6 K ohmsand the unit will start. This is the bin empty signal.
b) When ice is present within 1/2~1 inch of the sensor, theresistance at the K4 connector will be 15.8 K ohms and theunit will shut down within the first 5 minutes of the freezecycle. This is the bin full signal.
Note: Control board dip switch number 7 must be ON forthis control to operate the unit.

HOSHIZAKI KM CUBERSEQUENCE OF OPERATION
THE STEPS IN THE SEQUENCE ARE AS FOLLOWS:
NOTE: When power is supplied to the “E” Control board, a 5 second delay occurs at start-up.
1. 1 Minute Fill Cycle
The unit always starts in the 1 minute fill cycle. Whenpower is applied to the unit the water valve is ener-
gized and the fill period begins. After 1 minute the board checks for a closed float switch. If the float
switch is closed the harvest cycle begins. If not, theunit will not start without adequate water in the sump.This serves as a low water safety shut off. The watervalve will remain energized through additional 1 min-
ute cycles until water enters the sump and the float switch closes.
2. 1st Harvest Cycle
The compressor starts, hot gas valve opens, watervalve remains open and harvest begins. As the evap-
orator warms, the thermistor located on the suction line checks for a 48° F. temperature. When 48° F. is reached, the harvest is turned over to the adjustable control board defrost timer which is factory set for normal conditions. This adjustment can vary the de- frost timer from 1 to 3 minutes.
3. Freeze Cycle
After the timer terminates the harvest cycle, the hotgas and water valves close, and the ice productioncycle starts. For the first 5 minutes the controllerboard will not accept a signal from the float switch.This 5 minute minimum freeze acts as a short c y c l eprotection. At the end of 5 minutes the float switchassumes control. As ice builds on the evaporator thewater level in the sump lowers. Thefreeze continuesuntil the float switch opens and terminates iceproduction.
32 12/20/032/20/03
12/01/02
4. Harvest Pump Out
When the float switch opens and signals the completion of the freeze cycle, the harvest cycle begins. The hot gas valve opens and the compressor continues to run. The drain timer starts counting the 10/20 second pump out.
The water pump stops for 2 seconds and reverses,taking water from the bottom of the sump and forcingpressure against the check valve seat allowing waterto go through the check valve and down the drain. Atthe same time water flows through the small tube topower flush the float switch. When the drain timer
stops counting, the pump out is complete.
Pump out always occurs on the 2nd harvest after startup. The Alpine control board allows for adjustment for pump out to occur every cycle, or every 2nd, 5th or 10th cycle from this point.
5. Normal Harvest Cycle
The water valve opens to allow water to assist the harvest. As the evaporator warms, the thermistor reaches 48° F. The control board receives the thermistor signal and starts the defrost timer. The watervalve is open during harvest (defrost) for a maximum of 6 minutes or the length of harvest, whichever is shorter. When the defrost timer completes its count down, the defrost cycle is complete and the next freeze cycle starts.
The unit continues to cycle through 3 , 4 and 5 sequence until the bin control senses ice and shuts
the unit down.

KM CHECK OUT PROCEDURE
The following is a detailed explanation of the KM 10Minute Check Out procedure.
The 10 minute check out procedure is basically asequence check which can be used at unit start-up orfor system diagnosis. Using this check out procedurewill allow you to diagnose electrical system andcomponent failures in approximately 10 minutes undernormal operating conditions of 70°F or warmer air and50°F or warmer water temperatures. Before conductinga 10 minute checkout, check for correct installation,proper voltage per unit nameplate and adequate watersupply. As you go through the procedure, check toassure the components energize and de-energizecorrectly. If not, those components and controls aresuspect.
10 MINUTE CHECK OUT PROCEDURE1. Turn power OFF - gain access to unit control box.2. Turn power ON – place control switch in ice position.Note: A 5 second delay occurs for units with “E” controlboard.
A) 1 Minute Fill Cycle begins – WV energized.After 1 minute, control board checks FS. If FS isclosed…unit cycles to Harvest. Continue to (B).If FS is open, unit repeats 1 minute fill cycle untilwater enters and FS closes (low water safetyprotection during initial start up and at the end ofeach harvest)
Diagnosis: If WV does not open, check for no supplyvoltage at WV terminals, bad coil, or plugged screenor external filter (no water flow). If unit fails to startharvest, check for open FS or bad 1 minute timer inboard.B) Initial Harvest Cycle – WV remains energized,
CC energizes to start C, HGV, & (FM on RSmodel) energize. Evaporator warms…thermistorsenses 48°F…turns operation of harvest tocontrol board defrost completion timer. Timercompletes counting (1 ~3 minutes)…Unit cyclesto freeze.
Diagnosis: Check if C is running, HGV is open, WVstill open. Avg. harvest cycle at factory setting is 2~ 3 minutes. How long does initial harvest last? 1.5minutes after initial harvest begins, touch Cdischarge line. Is it hot? If not check refrigerantpressures and C operation. If it is hot, touch inletline to the evaporator. Is it hot? If it is hot and unit is

not starting freeze cycle, check defrostcompletion timer adjustment, thermistor for opencircuit, discharge line temperature, C efficiency,and if HGV is fully open.
C) Freeze cycle – C remains energized, PM, (LVon RS model), and FM energize…WV & HGVde-energize. Unit is held in freeze by 5 minuteshort cycle protection timer. After 5 minutesfreeze cycle operation to transferred to FS forfreeze termination. During first 5 minutes offreeze, confirm that evaporator temperaturedrops. After 7 minutes in freeze, remove blackFS lead from K5 connector…Unit shouldimmediately switch to pump out cycle.
Diagnosis: If evaporator is not cold, check for HGVstill open, TXV not opening properly, WVcontinuing to fill reservoir, improper unit pressures, and inoperative C. If unit remains in freezewith FS removed replace board. * Normal freezecycle will last 20 ~ 40 minutes depending onmodel and conditions. Cycle times andpressures should follow performance dataprovided in Tech –Specs.
D) Pump Out Cycle – (10/20 second pump out)C remains energized, HGV energizes, FM de-energizes, PM stops for 2 seconds and starts inreverse rotation for 10/20 seconds.( Thisremoves contaminants from the water reservoirthrough check valve and down the drain andallows for power flush of FS.) Check cleartubing at check valve housing or unit drain forwater flow.
Diagnosis: If PM does not reverse, check PM circuitand capacitor. If water does not pump out,remove housing and check/clean valveassembly.
E) Normal Harvest Cycle –same as Initial HarvestCycle – Return to B)…* Unit continues to cyclethrough B)…C)…& D) (Setting can be adjustedto skip D until every 2, 5, of 10 cycles)…until bincontrol is satisfied or power is switched OFF.• Unit always restarts at A).

RESERVOIR FLUSH SYSTEMA displacement device ( cap or assembly ) is positionedover the top of the overflow stand pipe. This device al-lows sediment to be pulled from the bottom of the reservoirand flush down the drain when overflow occurs. Watershould always overflow the stand pipe for a short periodtowards the end of harvest to allow this flushing action. Toextend this flushing action, adjust dip switches 1 & 2 forlonger harvest. If overflow does not occur, you likely haverestricted water flow into the unit. Check the inlet watervalve screen, incoming water line size, or the external filtersystem. The displacement device must be in position forproper operation. If not, water goes down the drain duringfreeze and short cycling occurs.
PUMP-OUT CHECK VALVEA mechanical spring & seat check valve is located inthe pump-out housing. If this check valve sticks open,water flows down the drain during freeze and a 5 minutefreeze cycle occurs. In this case, check for a displacedseat, trash or a weak spring. Replace the spring if it isweak. When reinstalling the check valve, the seat alwaysfaces the pump supply.
KML PUMP OUTThe Standard KM series has a dual winding pump motorthat reverses direction during the pump-out cycle. Thereverse rotation pumps sediment down the drain. The KMLmodels have a single winding pump motor that does notreverse. Instead of a pump-out check valve and reversingpump, a drain solenoid and the pump motor are energizedby a relay so that sediment is pumped out.
KM CONTROL SWITCHThe standard KM models have a three position controlswitch. The switch positions are “ICE-OFF-WASH”. Also, amanual cleaning valve includes a micro-switch which opensthe control transformer circuit to the control board duringthe cleaning process. This cleaning valve must be in thehorizontal position to make ice.
The KML models have 2 switches. The control switch po-sitions are “ICE- OFF-SERVICE”. With the control switch inthe SERVICE position, the SERVICE switch is energized.

CONTROL BOARD FUSEBeginning in May 2002 Hoshizaki began including a 10 Ampcontrol fuse on KM models. This new feature was addedto specific models as they were produced. The fuse islocated in a fuse holder that is mounted on the control boxand connected in the circuit supplying 115V to the controlboard 10-pin connector through pins 10 & 7.
The purpose of this fuse is to protect the control boardfrom damage in case of a short circuit in one of the compo-nents. This fuse will also offer some protection againstexternal wiring problems, voltage spikes, and surges.
If the fuse is blown, you should isolate each individualcomponent and check for shorts and grounded conditions.It is important that any external wiring connections, includ-ing the remote condenser circuit be checked before re-placing this fuse. If the problem is not corrected, the fusewill blow again.
In general, you should check the component that connectsto the pin that has a burnt trace on the back side of theboard first. The fuse is a Bussman AGC 10 Amp 250VACslow blow fuse, Hoshizaki part # 4A0893-07 and shouldonly be replaced with one of identical size and type. Areplacement fuse is taped to the control box.
Should you want to add this feature to an existing KM unitin the field, you can order fuse holder # 4A0892-01, fuselabel # 4A2817-01 and fuse # 4A0893-07, through yourlocal distributor. You should also make a note on the wiringdiagram indicating the fuse addition, fuse size and type.
On the following page, you will find a typical wiring dia-gram showing where the fuse is wired in the circuit andthe label that is included on the control box.
38
The service switch also has three positions, “DRAIN-CIRCULATE-WASH”. With the control switch in SERVICEand the service switch in DRAIN, the pump starts and drainvalve solenoid opens to automatically drain the reservoir.In the CIRCULATE position, the pump motor circulates cleanerto the outside of the evaporator. In WASH, the cleaningsolenoid energizes and the pump circulates cleaner to theinside and outside of the evaporator.

COMPONENT CHECKS:1.FLOAT SWITCH:Check out the float switch with an ohm meter. When thefloat is up, the switch is closed. When the float is down,the switch is open.
STICKING FLOAT SWITCH:It is important to remember that the float switch is in thewater circuit and is susceptible to scale buildup. This cancause the float to stick either up or down. If the floatswitch is sticking, it should be cleaned thoroughly with icemachine cleaner and checked for proper operation. If thefloat switch is defective, it should be replaced however, adirty float switch is not considered a warranty item.
The symptoms of a sticking float are:UP/CLOSED: 60 minute freeze cycle, larger cubes,and pump cavitates prior to harvest.
After 2 consecutive maximum freeze cycles, the unit will shut down on a 3 beep safety.
To reset this alarm, press the Alarm Reset but ton on the board with power ON.
DOWN/OPEN: Unit shuts down on low water safety and water runs continuously.
Heavy scale can be difficult to remove from the float. Thefloat is available as a replacement part as well as the floatpin. If the housing is defective, replace the complete floatswitch assembly.

2. THERMISTOR: Check out the thermistor mounting andcheck resistance versus temperature per this chart: THERMISTOR TEMPERATURE / RESISTANCE
SENSOR TEMP (F°) RESISTANCE (K OHMS)0 14.4
10 10.632 6.050 3.970 2.590 1.6
The symptoms of a bad thermistor are:OPEN: 20 minute harvest cycle. The unit will shut
down on a 2 beep safety after 2 consecutive 20 minute harvest cycles.
SHORTED: Unit locks out on manual reset high temp-erature 1 beep safety in this case.
High Temperature Safety: If evaporator reaches 127°Fthe thermistor signal (500 ohms) shuts down the unit onthis manual reset. A 1 beep alarm will occur. To reset thisalarm, press the Alarm Reset button on the boardwith power ON. Then check the items listed on the controlboard label for a 1 beep alarm.
UNIVERSAL REPLACEMENT FLOAT SWITCH:There are two styles of KM float switches. One has nohole in the outside pipe and one has a hole in the outsidepipe. Float switch number 4A0886-02 can be used as auniversal replacement on any KM unit. Simply seal off thesmall hole in the outside tube with silicone or a seal capfrom 3/8” refrigeration tubing if it is not needed.
CONNECTOR BOOT:The float switch boot will sometimes collect scale depositssince it is in a low area of the water circuit. The boot shouldbe cleaned thoroughly during scheduled maintenance. Dueto age and high amounts of chlorine in the local watersupply, it can also deteriorate and may cup upward in themiddle holding the float up . In this case, the boot should bereplaced. Order part number 426799-01 as universal re-placement part and cut the tube to length as needed.
Universal float boot # 426799-01 (Cut tube to length)
41 12/20/032/20/03
12/01/02
Note: The Thermistor must be mounted using a heatsink compound to assure good heat transfer and ac-curate sensing. Use Hoshizaki Part Number 4AO683-01 or equivalent. (Radio Shack #276-1372 or GE Elec-tronics #10-8108, ect.)
3. CONTROL BOARD: The electronic control board maintains the sequence of operation. There are 3 input connections to the board. 1. The Float switch connects to the control board through the black K5 connector. 2. The thermistor connects to the control board through the white K3 connector. 3. If a mechanical bin control is used, it will connect to the K4 Red connector. ( In this case, dip switch #7 must be set to the ON position.)
The control transformer supplies 10.5 VAC control voltage to the K2 connection. The control board will not operate unless control voltage is present at K2. Proper control voltage is indicated by the Power OK red LED ON.
The final connector on the control board is the K1 10-pin connector. This connector supplies 115 VAC into the control board switchin components or relay contacts and powers the individual com- ponents during the sequence of operation.
The control board also has 10 dip switches that allow for board adjustments. These switches are set from the factory for proper operation and maxi- mum efficiency. See control board adjustment chart for factory settings and adjustments.
BOARD CHECKOUT: Before replacing a control board that does not show a visable defect and that you suspect is bad, always conduct the fol- low checkout procedure. This procedure will help you verify your diagnosis.
1. Check the dip switch settings to assure that #3,4, 7, 8, 9, & 10 are in the factory setting. Out- put test switch S3 should also be OFF. Switches 1, 2, 4, & 5 are cleaning adjustments and the set- tings are flexible.
42 12/20/032/20/03
12/01/02
2. Turn the control switch to ICE and check for proper control voltage. If the Red LED is ON, the control volt- age is good. If the Red LED is OFF, check the control transformer circuit. See checking control transformer.
3. Next, check the 115 volt input at the 10-pin connector. Check the brown wire at pin #10 to a white neutral wire for 115 volts. (Always choose a white neutral
wire to establish a good neutral connection when checking voltages.) A jumper also feeds 115 volts into pin # 7. If no voltage is present, check the 115 volt supply circuit.
4. Check the board sequence using the S3 output test. a) Turn the control switch to OFF and switch S3 ON. b) Turn the Control switch to ICE and watch the light- ing sequence of the 4 green LED’s numbered 1, 4, 3, 2 from the board edge. The Red LED should light in
about 3 seconds. About 3 seconds later, LED 2 should light. 5 seconds later, Led 2 will go out and LED 3 will light. 5 seconds later, Led 3 will go out and LED 4 will light. 5 seconds later, Led 4 will go out and LED 1 will light. 5 seconds later, Led 1 will go out and LED 4 will light. This sequence completes the output test and the unit
is now in the 1 minute fill cycle.
Note: If the LED’s light in a different sequence or the 5-second interval does not occur as explained, the controlboard is bad and should be replaced. If the test sequenceis correct, turn the control switch OFF and switch S3 OFF.The S3 switch must remain in the OFF position during nor-mal operation. The components will cycle during this test.
5. You have checked the board sequence and nowneed to check the output to each component throughthe K1 10-pin connector for 115 volts. Follow the wir-ing color code on the wiring diagram or use the generic
drawing in the wiring diagram section to check each component for 115 volts through out the sequence and check from each pin to a white wire.
Note: Checking from pin to case ground can give a falsereading in some instances. Always choose a white neu-tral wire to establish a good neutral connection whenchecking voltages.

4. BIN CONTROL: Checkout for the bin control will vary depending on the
model and control that is used.
a) THERMOSTATIC BIN CONTROL: The thermostaticbulb is mounted in the ice drop area to sense the icebuildup. To adjust the bin control, hold ice against thebulb while the unit is operating. You will find it easier toplace the control switch to the wash position to checkthe bin control operation. It is easy to hear the pumpmotor stop when the bin control opens. The unit shouldshut down within a 10 second window when thecontrol is adjusted properly. If this does not occur,adjust the thermostatic control by turning the screw-driver slot. Adjusting towards warmer will allow theunit to shut down quicker. This adjustment should bechecked at installation, when diagnosing a bin controlproblem, or if a replacement bin control is installed.
KM 150 / 250 / 280 / 500 / 630 /900 units have a bincontrol mounted in the ice drop zone area. KM-1300M /S and larger units have a drop down bracket that mustbe dropped down, secured, and plugged in at installa-tion. The ice must contact the bulb to operate thebin control. Some bin applications require an exten-sion bracket or relocation of the bulb mounting to allowfor proper shut down. Check this positioning if thecontrol is adjusted properly and ice continues to backup into the evaporator section. Assure that the exten-sion bracket is installed.
The symptoms of a bad thermostatic control are:STUCK CLOSED: The unit continues to operate when thebin is full. This allows ice to back up in the evaporatorcompartment and generally causes a freeze up condition.This will also occur if the bin control is adjusted too cold orfully “CW”. Check the adjustment and bulb location beforeyou diagnose a stuck bin control.
STUCK OPEN: The unit will not start in the ice position. Aneasy method to check for an open bin control is to flip thecontrol switch to WASH. If the pump starts, the bin controlis closed.
b) MECHANICAL BIN CONTROL: The mechanical bin control uses a moving actuator paddle to open and
44 12/20/032/20/03
12/01/02
closes a magnetic proximity switch. The control is con- nected to the red K5 connector on the control board through a resistor harness. As the proximity switch opens or closes, the resistance will change to signal the control board to start up or shut down. The control board will only respond to this change in resistance during the first 5 minutes of each freeze cycle.
Note: Dip switch # 7 must be in the ON position for this control. When dip switch # 7 is ON, the following 2 safeties will occur if the mechanical control fails: 4 Beeps = Short circuit on K5 bin control circuit. 5 Beeps = Open circuit on K5 bin control circuit.
To reset either safety, press the white reset button on the control board with the power ON.
CHECKOUT: To check this control with the unit running, you must be in the first 5 minutes of the freeze cycle. Turn the control switch to OFF and back to ICE. Allow the unit to cycle through the 1 minute fill cycle and the initial harvest cycle. Once the freeze cycle begins (LED 1 ON and when you hear the pump motor start you will know that the freeze cycle has begun), push the control paddle to the full right position and the unit should shut down within 3 seconds.
Another method to check this control is to unplug the wiring harness from the K5 Red connector and check the resistance at the end of the harness with an ohm- meter as the proximity switch opens and closes.
1) When the control paddle is hanging in the normal position, (Bin Empty) the resistance at the red K4 connector will be 7.9 K ohms. 2) When the control paddle is held to the full right position, (Bin Full) the resistance at the red K4 connector will be 15.8 K ohms.
c) CAPACITIVE PROXMITY SWITCH: This control is used on the KM-1300NRF model only. It operates with the same sequence as the mechanical control and has the same safeties. The difference is that this control has a separate 24VDC power supply and operates through a bin control relay.

CHECKOUT:To check the operation of this control follow the same checkout procedure as with the mechanical control. Instead ofmoving a paddle, you will place your hand within 1/2~1inch of the sensor end. With the control switch in ICE, youshould hear the bin control relay switch when you moveyour hand away from the sensor end and back again.
Check the resistance supplied at the Red K4 connector asyou move your hand back and forth at the sensor end.Unplug the harness and use an ohmmeter to check theresistance. As the sensor switches, the resistance valuewill change as follows:a) When your hand is away from the sensor end, theresistance at the K4 connector will be 5.6 K ohms. This isthe bin empty signal.b) When your hand is within 1/2~1 inch of the sensor, theresistance at the K4 connector will be 15.5 K ohms. This isthe bin full signal.
If the relay does not switch or the resistance does notchange, check the control wiring, relay operation, and thecontrol power supply for 115 VAC input / 24 VAC output.
Note: Remember that dip switch # 7 must be ON and thecontrol will have these safeties. 4 Beeps = Short circuit on K5 bin control circuit. 5 Beeps = Open circuit on K5 bin control circuit.
F/DCM BIN CONTROL:DCM bin controls may be a mechanical flapper with a mag-netic proximity switch or a micro-switch assembly. Sincethese controls have moving parts, make sure that all partsmove freely. Sticking can occur if scale builds up at thepivot points. All flakers except the F-450MAF-C use themechanical/proximity switch control. If the bin control fails,the spout will fill with ice causing higher gear motor currentand the gear motor protect fuse will blow.
The F-450MAF-C has an infrared eye bin control. A sepa-rate power supply provides 24 VDC to the infrared eye.This power supply is mounted in a separate control boxalong with the bin control relay. The IR sensor is mountedon the outside of the chute base in a molded indentation.Two mounting holes mount the sensor to the chute base.
46 12/20/032/20/03

The sensor has two LED lamps that light to show thatpower is supplied. Since the voltage is DC, the sensor ispolarity sensitive. The sensor has four wires. The orangewire is capped off and not used. The black wire connectsto the coil of relay X7. The brown wire is the positive leadand connects to terminal J2-1 on the power supply. Theblue wire is the negative lead and connects to terminal J2-2. If these wires are crossed, the sensor will not shut theunit down. The result will be that the spout will fill with icecausing higher gear motor current and the gear motor pro-tect fuse will blow. In this case, the bin control is the firstcomponent to check.
The sensor has two adjustments that are factory set. Thefirst adjustment sets the operation mode of the sensor. Itmust be in the D position. The second adjust the operatingdistance of the infrared beam at approximately 4”. It shouldbe set so that the white dot on the dial is at 12 o’clock (topdead center). These settings should not be altered.
5. KM CONTROL TRANSFORMER: The KM control trans-former supplies 10.5 VAC to the control board through theK2 connector. This 115V/10.5V stepdown transformer is aheavy duty component with an internal thermal overload.The primary winding of this transformer will handle highervoltage without damage because the thermal overload willopen to protect the winding in the case of improper supplyvoltage. The control board monitors the output voltage ofthis control transformer and provides automatic reset highand low voltage protection.
The red LED on the control board will not light if no controlvoltage is supplied. The 115V transformer primary circuit issupplied through the thermostatic bin control, control switch,high pressure switch, and low pressure switch if included.If either of these switches are open, there is not controlvoltage at the K2 connector and the unit will not operate.
The transformer secondary circuit includes the cleaningvalve interlock switch. If this switch is open, no controlvoltage is supplied to the K2 connector so the unit will notoperate. Always check the cleaning valve position andinterlock switch if the red LED is off.
Because of the voltage protection, if the control trans-former fails, it is important to use the correct OEM part.

6. KM PUMP MOTOR ASSEMBLY:The KM pump assembly has a dual winding PSC motor withan internal overload. The motor has a cast housing andsealed stainless steel roller bearings. No lubrication isrequired for these roller bearings.
If the pump motor fails, always repalce the pump motorcapacitor. If other failures occur, the front end of the pumpassembly is rebuildable. The mechanical seal is the mostcommon failure part and can be replaced.
Following, are the assembly breakdown’s for two genericpump assemblies. Use these drawings as a guide to reas-semble a pump assembly that you are rebuilding.

7. INLET WATER VALVE: Hoshizaki uses inlet water valvesolenoid to fill the reservoir for ice making. This constantduty solenoid valve is very reliable however, in areas ofhard water and high levels of chlorine, the diaphragm issusceptible to failure.
Water quality is constantly changing and local municipali-ties are now adding higher levels of chlorine, chloramine,and chlorine dioxides to the water. These agents can dam-age rubber parts and effect the diaphragm life.
The diaphragm is made of rubber and ABS and has a bleedport on the inside ABS piece. This port allows the pressureto balance on the top and bottom of the diaphragm so thatthe valve will open and close properly with the springpressure. If the rubber becomes dry and brittle or thebleed port is plugged with trash or debris, the valve willleak by. In this case the valve can be disassembled forcleaning and the diaphragm and inlet screen can be cleanedor replaced. It is important to remember that the warrantycovers repair of defects and not cleaning. Should the valvebe scaled or dirty, it should be cleaned and bill to the cus-tomer.
Below you will find an exploded view of the valve assem-bly and instructions for reassembly of the valve. Whenreplacing the diaphragm and re-assembling thevalvereplacing the diaphragm, it is important that the plungeris in the correct position. This plunger has a white plasticseal on one end and is metal on the other end. The whiteseal end of the plunger must be in contact with the dia-phragm in order for the valve to work correctly.

Diagnosing water problems.
Many common water related problems will cause cubes tolook unnatural. Looking at the ice in the bin will point youtowards the problem area. Study these shapes and causesto help you diagnose water related problems.
1. Normal cube, No problem.Average cube size 1/2” thick x1 1/8” wide x 1 1/2” high.
2. Larger than normal cube with heavysaddled edges.Note: Normal cube may have slight saddled edge.
If the float switch sticks in the up position, (closed ) theunit will have a consistent 60 minute freeze cycle. Thiswill result in heavy saddled edges and may cause pumpcavitation and ice to stick on the evaporator or ice pos-sible bridging.
A FREEZE UP MAY OCCUR IF ICE STICKS DUE TOTHE LARGER EDGES.
52 12/20/032/20/03
12/01/02
3. Bridging or ice stripsa) Bridging that occurs on all ribs of all evaporator plates
is the result of excessive water in the reservoir. This iscaused by the inlet water valve leaking by. Check for aplugged bleed port in the water valve diaphragm or adefective water valve.
b) May be the result of # 2.c) Bridging can occur on a few ribs if some of the holes in
the water distribution tubes are plugged. An inspectionof the ice build up on the evaporator will show some ribswith no ice and others with strips. Clean the waterdistribution system.
d) Bridging on 1 or 2 plates of a multiple evaporator unitcan result from water distribution problems or a refrig-eration system problem. Eliminate water problems firstthen check TXV, hot gas valve, charge, etc....
BRIDGING WILL GENERALLY CAUSE A FREEZE UP.
53 12/20/032/20/03
12/01/02
4. Melt away of back of cubea) This can occur if the evaporator plate is scaled up.De-scaling is required. b) Insufficient water flow during harvest can also cause
the flat side of the cube to melt away. Check for aplugged inlet water valve screen, plugged externalfilter, low water pressure, or a small water line size.
EITHER OR BOTH OF THESE ITEMS CAN CAUSETHIS SYMPTOM.
5. Small cube
a) Can be caused by a low volume of water at the begin-ning of freeze. Check for adequate water flow duringharvest. See item 4 b)
b) If the pump out check valve is stuck open or has aweak spring, the water left in the reservoir will bepumped out during the first five minutes of freeze.This results in a short cycle and slivers of ice or smallcubes.
c) Any loss of water, whether by leak, water trail, orloose stand pipe can cause this problem.
6. Freeze ups can be caused by 2, 3, or 4 above in anycombination. The major cause however is a dirty(scaled up ) water system or evaporator. A thoroughcleaning will eliminate most freeze ups. The secondmost common reason for freeze up is low water flow.Always check the evaporator, and water flow first,then go to other checks when diagnosing freeze ups.
(Size will depend on how much water isin the reservoir.)

PREVENTATIVE MAINTENENCE: Perventative Maintenanceis the key to long equipment life and maximum efficiency.Hoshizaki recommends preforming the following mainte-nance steps at least annually. The PM frequency will de-pend on the local water quality and operating conditions.
PREVENTATIVE MAINTENANCE STEPS:1. Clean the removable air filter. Hoshizaki air-cooled unitsinclude a front accessible, cleanable air filter. This filtercollects dirt, dust, and grease can be cleaned with warmsoapy water. Hoshizaki recommends cleaning the air filtertwice a month or more as conditions dictate.2. Service the external water filter system (if equipped)and check and clean inlet water valve screen.3. Clean and sanitize the water system and bin. A cleaninglabel with detailed instructions is usually located on theinside of the front panel.4. Check bearings for wear annually on Flaker/DCM.Pull the auger and inspect evaporator, auger, and bearingsurfaces for wear. More frequently bearing inspectionsmay be needed in areas with poor water quality.5. Visually inspect the unit for loose wires, oil spots, waterdrips, etc.6. Clean & wipe exterior with a soft cloth and neutral cleaner.
STAINLESS STEEL CLEANING:Water quality is constantly changing and local municipali-ties are now adding higher levels of chlorine, chloramine,and sometimes, chlorine dioxides to reduce bacteria in thewater. Stainless steel is a durable metal however it can besuseptable to corrosion from exposure to chlorine gas.
As ice forms on a cuber evaporator, chlorine outgases andthe chlorine gas settles in the lowest point in the bin. Thisgas sticks to wet surfaces and around the mouth of the binand forms hydrochloric acid. If this acid remains on thestainless steel, rust colored corrosion occurs. With enoughexposure, the corrosion can pit and damage the stainless.
If rust colored corrosion is found, it should be cleanedthroughly with a non-abrasive cleaner and protected witha stainless steel polish. Heavy corrosion will require someeffort to remove and may require the use of a cleaningagent like “Brasso” or non-abrasive powdered cleaner like“Zud” or “Bon Ami”. Care should be taken so as not toscratch the stainless during the cleaning process.

CLEANING/SANITIZING PROCEDURE
A label which details the step by step cleaning/sanitizingprocedure is located on the inside front panel of the icemachine. These instructions are also provided in the In-struction Manual shipped with each unit. Follow these in-structions to conduct a thorough cleaning and sanitizing ofthe water system.
Annual cleanings are recommended. More frequentcleanings may be required in bad water areas.
INLET WATER VALVEThe inlet water valve includes an 80 mesh screen to pro-tect the water system from debris. Always check andclear this screen during the cleaning procedure.
CLEANERS:Hoshizaki recommends "Hoshizaki Scale Away' or "Lime-A-Way" (by Economics Laboratory, Inc.) however any FDAapproved ice machine cleaner is acceptable. If you carry anickel safe cleaner, the acidic solution is weaker than nor-mal cleaners to protect plated surfaces. You may need touse a heavier mixture of nickel safe to cut heavier scaledeposits.

KM PRODUCTION CHECKThe steps for a cuber production check are as follows:
1. Time a complete cycle from the beginning of onefreeze cycle to the beginning of the next freezecycle.
2. Catch all of the ice from this freeze cycle andweigh the total batch.
3. Divide the total minutes in a 24 hour day (1440minutes) by the complete cycle time in minutes toobtain the number of cycles per day.
4. Multiply the number of cycles per day by the cyclebatch weight for the cuber production per 24
hours.
(1440 • Total Cycle Time) x Ice Batch Weight=24 Hour Production
Once you calculate the production, check the incoming wa-ter temperature, and ambient condensing temperature at thecuber and cross reference to performance data included inthis manual to see if the calculation falls within 10% of thespecification.
For the most accurate production check, a normal freezecycle should be checked. If the evaporator compartment hasbeen opened for service or if the unit has been cut off for along period of time, the first freeze cycle will be longer thannormal. Timing this cycle can result in an inaccurate produc-tion check. To avoid this, start the unit and allow it to operatefor 10 minutes in the freeze cycle, unplug the float switchlead and cause the unit to cycle into harvest mode. Replugthe float switch and start timing as soon as the next freezebegins. Also remember that the evaporator compartment mustbe closed during the production check. Removing the frontcover to check the ice buildup during a production check willallow heat into the evaporator and will affect the total cycletime and actual production.

FLAKER/DCM
INSTALLATION - GENERAL
As always, you should follow the installation instructionsthat are provided in the instruction manual supplied withthe unit. You will also find a yellow instruction sheet at-tached to the top of a new unit. This sheet highlights theinstallation steps. Three things are critical for a proper F/DCM installation:
1. The water temperature should fall within the 45° Fto 90° F range.
Colder water can cause excess stress on theauger gear motor which may activate the gearmotor overload.
2. A filter system is very important in poor waterquality areas as high mineral content can causepremature bearing wear.
3. The unit should be level, front to back, side toside to assure proper evaporator water level andmaximum production.
CUBELET MODELS
The DCM product produces Cubelet ice. Certain flaker mod-els can also be converted to produce cubelet ice. Thisrequires changing the extruding head and cutter at the topof the evaporator assembly. The F-450M, F-800M, and F-2000M models are produced as cubelet models and aredesignated by a - C at the end of the model number.
Converting a flaker to a cubelet maker reduces the overallproduction by around 8 %. The flaker gear motor is sized tohandle the extra load of producing cubelet ice with only aslight increase in the running amperage. The evaporatoroutlet temperature and operating pressures will be similarto the standard flaker model. Use the temperature andpressure information provided on the standard flaker per-formance data provided as a bench mark when diagnosinga converted cubelet (- C) unit.
141 12/20/032/20/03
12/01/02
INTERNAL AUGER DESIGNHoshizaki Flakers and DCM’s use an internal auger systemto provide high quality crisp flakes and cubelet ice. Theevaporator cylinder and auger are made of anti-magneticstainless steel. This higher quality stainless steel elimnatespitting caused by harmful minerals in the water. This main-tains a smooth surface to reduce ristriction to ice flowproviding consistant production and quality.
The picture below is a generic breakdown of the F/DCMevaporator assembly. The extruding head # 9 and cutter#12 can be exchanged so that this Flaker assembly willproduce Cubelet style (chunklet) ice like the DCM applica-tion. The sleeve type alignment bearings are pressed intothe housing # 4 and extruding head # 9. The mechanicalseal # 6 and “O” ring # 5 seal the lower end of the evapo-rator system.

COMPONENT TECHNICAL DATA
CONTROL TRANSFORMER
Hoshizaki Flaker units include a 24 volt control transformer.This transformer has a 115 volt primary and 24 voltsecondary and is protected by a 1Amp control fuse. (TheDCM has a dual output secondary of 10.5/24V) The 24 voltsecondary supplies power to the solid state timer board,relay coils, inlet water valve and flush timer circuit. Theflush valve will be either 24 volts AC or DC, depending onthe model. A rectifier is provide in the flush valve circuit toconvert to DC. Without control voltage on pins 1 and 2, thetimer board will not allow the unit to start.
GEAR MOTOR PROTECTION
The auger gear motor circuit includes two overload safe-ties. The primary safety is a manual reset, current typeprotector or slow blow fuse located in the control box. Thisis a time delay protection which operates if high amp drawoccurs. The secondary safety is a thermal protector whichis incorporated into the gear motor windings.
The current type gear motor safety has been replacedwith a slow blow fuse on most models. The Fuse providesmore consistant protection in low voltage applications.

Gear motor failure can be expensive and it is very impor-tant to find the cause of the failure when it is replaced.There are several possibilities for the cause of gear motorfailure. The following check list is designed to help you findthe reason your failure occurred.
143 12/20/032/20/03
12/01/02144
F-1000M GEAR MOTOR CHECKOUT
NORMAL AMPERAGE: The amperage for the F-1000Mgear motor should be 0.6~1.0 amps with no load and 1.0~1.4amps when making ice. Answer the following questions to discover the possiblecause for your failure: 1. Is Ambient Temperature above 45 degrees F.2. Does the unit have the Wrong Extruding Head. Checkthe Extruder Type. Is it a Flaker or Cubelet style. (Thecubelet style head will have smaller openings for the ice toextrude.) 3. Does the unit have the Wrong Cutter. The cutter shouldmatch the extruding head style. Flake or Cubelet. 4. Do you have a Damaged Extruder. Look for followingimperfections. A. Dents B. Fins BentC. Scale D. Other Resistance 5. Does the unit have the Correct Auger. Is the auger adual flight auger? (Double Spirals) Check the parts break-down for the correct auger style. 6. Check the Voltage Supply and circuit amperage. Is thisunit on it’s own dedicated circuit? The supply voltageshould be within +/- 10% of the rated voltage when the unitis making ice. 7. Check the Running Voltage at the gear motor. (Whilethe unit is making Ice.) 8. Inspect bearings for wear. ( Use bearing gauge ) Arethe Bearings OK? If the upper bearing is worn, both bear-ings should be replaced. 9. Check Evaporator Cylinder/ Barrel for signs of scoring. 10. Is there any condensation dripping onto the Gear Mo-tor windings? If yes, find the source and take action tostop the moisture. 11. Is the galvanized shield mounted over the motor as-sembly? 12. Verify that you have the proper Gear Motor Capacitor. 13. Is the Gear Motor Locked. Check motor winding resis-tance.
2. WRONG GEAR MOTOR OVERLOAD / FUSE:Check fuse size. Has the original overload reset been re-placed with the fuse kit? The M_F Flaker requires BussmanGMD 1.5A Fuse P/N 4A0893-04. The M_F-C Cubeletrequires Bussman GMD 2.0A Fuse P/N 4A0893-05. Thisfuse is a slow blow type. Replacing it with a standard fusewill cause the fuse to blow again.
12/20/032/20/03
12/01/02
Although it is common practice to install a larger fuse dur-ing service diagnosis, you should not leave a larger fuse inthe unit when you leave the site. This could cause a seri-ous unit failure.
3. MISWIRINGIs gear motor wired correctly and wire connections tight.Check the wiring diagram for the proper wiring.
4. BIN CONTROL SWITCH DOES NOT OPERATECheck the bin control operation. A bad or miswired bincontrol can cause ice to back up in the spout and chute andcause higher gear motor amperage. Is Bin Control wiredcorrectly and are the wire connections tight.
Make sure there are no metallic components interferingwith the magnetic bin control. Verify top panel is non-mag-netic. Assure that the proximity switch is mount properly.The switch must be secure and mounted level to the chutetop. Does the Bin Control Paddle move freely and is itunobstructed?
As you can see, there are many factors that can cause agear motor to fail. A gear motor check list comes with aservice replacement part. The check list can be used as adiagnostic tool. If the gear motor is under warranty, thechecklist should be completed and submitted with the war-ranty claim.
GEAR MOTOR STRESS
When looking for the cause of a gear motor failure, youshould consider anything that will add stress to the assem-bly. Stress on the gear motor will increase the gear motoramperage and torque. The most common causes for stressis scale on the auger surface and evaporator walls. Scalensulates the evaporator walls and causes reduced heattransfer. As a result, the ice will be wet and mushy. Thispoor quality ice does not extrude well and tends to pack inthe evaporator outlet.
Heavy scale build up must be removed using an acid basedcleaner which will loosen the scale. Follow the cleaninginstructions provided on the cleaning label to preform amaintenance cleaning. If the unit has not been cleaned andmaintained frequently, it may require you to pull the auger
145 12/20/032/20/03
12/01/02
and clean the cylinder wall with a Scotchbrite pad & cleaner.The extruding head surface may also have heavy scaleand can be cleaned with Scotchbrite & cleaner as well.
AUGER BEARINGS: Bearing Type: Sleeve/Alignment, Bearing Material: Poly/Carbon
The bearings are pressed into the top extruding head andlower brass housing. A repress program is availablethrough the local Hoshizaki Distributor for undamaged ex-truding heads and housings. The bearings should alwaysbe replaced as a set. Return the extruding head and hous-ing to your distributor for an exchange set or to be returnedfor repressing.
BEARING INSPECTIONS:
Annual bearing inspections are recommended. More fre-quent inspections may be necessary in poor water qualityareas. The steps for bearing inspections are as follows:
(1 ) Gain access to the ice chute head by removing the toppanel and spout connectors as necessary.
(2) Remove the thumbnuts which hold the ice chute head inplace and lift it up and off of the evaporator (take care toplace the O-ring in a safe location until you replace thehead.)
(3) Remove the stainless steel bolt holding the cutter orbreaker in place and lift off to access the extruding headand auger shaft.
(4) Replace the bolt into the auger shaft and use it to pushthe auger back and forth from left to right to check forexcessive movement.
(5) Pull the auger towards you and try to insert a .02” roundstock or pin gauge in between the back side of the augershaft and bearing surface. Check several locations aroundthe auger shaft. If the gauge will go in between the shaftand bearing, it is time to install new bearings. Both top andbottom bearings should be replaced if the top bearing isworn. If there is no excessive movement in the auger shaftand the gauge does not fit, the bearings are okay. Replacethe cutter, O-ring, ice chute head and connectors.

12/01/02
AUGER INSPECTION / BEARINGREPLACEMENT
A visual inspection of the auger bearing shaft surface isalso recommended annually in poor water areas. The stepsfor this inspection is as follows:
Note: Clean the evaporator prior to removing the auger.This will loosen scale around the extruding headand allow for easier removal.
(1) Follow steps 1 through 5 of the bearing inspection pro-cedure above.
(2) Remove the (metric) Allen head cap screws that se-cure the extruding head in place.
(3) Thoroughly drain the water supply system.
4) Turn the cutter up-side down, replace the bolt and usethe cutter to lift the auger out of the evaporator. If heavyscale is present the auger may be difficult to remove. In thiscase, you will find it helpful to clean the evaporator systemfollowing the instructions located on the Inside front panel,before you attempt to remove the auger.
(5) With the auger removed, remove the cutter and slidethe extruding head from the top of the auger. Visually in-spect the bearing surface at the top and bottom of theauger. Also inspect the auger flight and mechanical seal forany damage. The extruding head contains the top bearing,the bottom bearing is pressed into the brass housing at thebottom of the evaporator. To remove the housing:
(6) Remove the Allen screws that secure the evaporator tothe housing.
(7) Loosen the belly band screw and lift the evaporator up

Flaker Safety’s Mechanical failures in an auger style ice machine can betime consuming and expensive repairs. Hoshizaki has in-corporated several safety’s in our Flaker and DCM unitswhich add protection against this type of failure.
The following safety’s are included in all Hoshizaki F andDCM units:1. Low water safety: Designed to protect against dryoperation or possible freeze up in the evaporator due tolow water flow. This safety utilizes the dual float switchand a 90 second timer to shut down the unit when waterflow is interrupted. The unit will automatically restart whenwater flow is resumed.
2. Protect relay safety: This safety incorporates a relay inthe gear motor circuit and will not allow the refrigerationsystem to operate unless the gear motor is running. If thegear motor fails during normal operation, the protect relayshuts down the compressor to protect against evaporatorfreeze-up.
3. Gear motor circuit safety’s: The gear motor has 2additional safety’s which will operate if the gear motor issubjected to excessive load or improper voltage. A currenttype manual reset safety or slow blow fuse is located inthe control box and will trip when the gear motor amperageexceeds normal amp draw. This acts as a primary safetyfor the gear motor. A secondary internal thermal overload
and off of the housing. Holding the evaporator up, re-tightenthe belly band. This will hold the evaporator up so that youcan remove the housing.
(8) Remove the bolts that secure the housing to the gearmotor assembly and remove the brass housing. The me-chanical seal ceramic disk and boot are pressed into thetop of the housing. Remove these parts before you ex-change the bearings. The extruding head and brass hous-ing will be exchanged for a repressed set at your localdistributor. When you replace the new parts, reverse theorder above. Use a light coat of food grade lubricant aroundthe bottom of the evaporator and on the o-ring portion ofthe housing to the seal o-ring and help keep it in place asyou lower the evaporator. Inspect the mechanical seal thor-oughly and reuse it, if it is in good shape.

is included in the motor windings. Both will work in con-junction with the protect relay to shut the unit down.
4. Voltage protect relay: This relay will shut the unit off incase of a voltage surge and automatically restart the unitwhen the voltage is correct.
5. High pressure switch: All Hoshizaki ice machines in-clude an automatic reset high pressure safety switch toshut down the unit in case of high head pressures.
6. Fuse protection: A lamp buss-type fuse is utilized in thecontrol circuit. Smaller units like the DCM-240 and F-300have a fuse in the incoming power circuit.
7. Short cycle protection timer: A 1 minute time delay isincluded in the start-up sequence to protect against shortcycling the gear motor or compressor.
8. Compressor protection is provided either internally or bymeans of an external motor circuit protector. This is anautomatic reset thermal type circuit breaker.
9. The F-2000 has a spout safety control to shut down theunit if the bin control fails for any reason. This is a manualreset safety and will notify the technician by means of aindicator light on the control box. To reset this safety, turnthe control switch OFF and back ON. This re-sets the hold-ing relay circuit and turns off the light.
The gear motor current protector serves as a back-up forthe bin control on other models. These safety’s protect theFlaker or DCM models from internal failures.

Hoshizaki float switch, part number 435490-01 can be usedas a universal replacement on any Hoshizaki Flaker or DCMmodel in the field. It now subs for all previous float switchnumbers in our parts system.
Since the float switch is mounted into the water reservoir,it is susceptible to scale build-up. The amount of scalebuild-up will depend on the local water quality. Scale on

the switch shaft can cause the floats to stick. This willeffect the unit operation. In this case, the float switchshould be cleaned and checked.
The float switch is held in place on the top cover by a twistlock bracket. To remove it, twist the switch flange and lift.Soak the switch assembly in ice machine cleaner. While itis not necessary to do so, some technicians remove thefloats from the shaft during cleaning. If you remove them,note that the blue float is on top. Also it is important toclearly mark the top of the floats so that they can be re-placed correctly. (See drawing below). Installing the floatsupside down will effect the timing of the float switch op-eration. Once clean, rinse and wipe the cleaner off andcheck the switch with a good quality ohm meter.
This float switch has three wires (the black wire is com-mon) and two separate switches. Check the top switchby ohming out the black and red wires. When the float is upthe switch should be closed. Check the bottom switch byohming out the black and blue wires in the same manner. Ifeither switch fails, the assembly should be replaced.

FLAKER WATER FILL SYSTEMThe reservoir in a Hoshizaki auger type ice maker feedswater by gravity flow to the evaporator cylinder. The levelof water in the reservoir is maintained by the operation ofthe dual float switch.
The dual float switch assembly is made up of two reedswitches inside of a sealed shaft. The reed switch con-tacts are operated by individual magnets attached inside ofthe two separate floats.
As ice is made and extruded from the evaporator cylinder,the water level in the reservoir drops. When the level drops,the top float opens the top switch contacts (considered alatching circuit). Opening these contacts allows the bot-tom float switch control of the water control relay in thecontrol circuit. As the water level continues to drop, thebottom float contacts open to de-energize the water con-trol relay.De-energizing the water control relay closes a circuit tosupply 24 volts to the inlet water valve solenoid. This al-lows water to fill the reservoir. It also opens a circuit to thetimer board which starts a 90 second low water safetyshutdown timer.
When the water supply is available, the reservoir refills.As the reservoir level rises, these two switches swapjobs. The bottom float is now the latching circuit and thetopfloat re-energizes the water control relay. This will stopthe safety timer and shut off the water flow.
If no water is available, i.e. the filter is stopped up or thewater supply is turned off, the unit cycles down and thewater valve remains energized. When the water supply isrestored, the reservoir fills and the top float switch re-energizes the water control relay to automatically restartthe unit. This system provides a consistent water level inthe reservoir and an automatic reset low water safetyprotection.
Since the float switch is mounted into the water reservoir,it is susceptible to scale build-up. The amount of scalebuild-up will depend on the local water quality. Scale onthe switch shaft can cause the floats to stick. This willeffect the unit operation. In this case, the float switch
should be cleaned and checked.

FLAKER TIMER BOARD
The solid state timer board used in Hoshizaki Flakers is asimple electronic sequence timer. In order for the board tosequence, certain circuits must be closed. In order to diag-nose a bad timer board, it is necessary to check thesecircuits to assure they are operating properly. If you aretrouble-shooting a timer, the first thing you should check isthe in coming control voltage. All Hoshizaki flakers have a24 volt control transformer. The output of this transformeris protected by a 1 amp buss type fuse. Control voltagecomes in the timer on pins 1 & 2. If you do not have 24 voltsat pins 1 & 2, check the transformer and fuse.
Now check for 24 volts across pins 7 & 8. If voltage ispresent, the timer board has cycled up which indicatesthere is not a problem in the timer board. The problem is inthe gear motor relay circuit. remember that there is a timedelay from the time you turn the unit on to the time it cyclesup completely. this time will be from 1 ~ 2.5 minutes, de-pending on the model of flaker.
In order for the flaker to start up, the reservoir must be fulland both float switches must be closed. This closes thecontrol circuit to pins 3 & 4. Do not confuse these pins withthe line voltage terminals marked 3 & 4 on the compressorrelay located on the board. You can check this circuit witha volt meter across the pins or by placing a jumper acrossthem. If the unit cycles up with the jumper in place, theboard is good and your problem is in the water relay con-trol circuit.
Next, you should check the bin control circuit at pins 5 & 6.Check for a closed circuit with a volt meter or place ajumper across them. If the unit cycles up with the jumperin place, the board is good and the bin control circuit is theproblem.
The last circuit check is across pins 10 & 11. These pinsconnect to the gear motor protect relay and will shut downthe unit if the gear motor fails. Check for a closed circuitwith a volt meter or place a jumper across them. If the unitcycles up with the jumper in place, the board is good andthe gear motor protect circuit is suspect.

Flaker Sequence of Operation
The Hoshizaki Flaker utilizes a solid state sequence timerboard to switch the components on and off as needed.The sequence is as follows:
With proper voltage and water supplied to the Flaker andthe flush and ice switch is in the ice position, power issupplied to the inlet water valve. The unit will not startunless the reservoir is full and both floats on the dual floatswitch are closed (in the up position). The operation isthen turned over to the bin control. If the bin control isclosed and calling for ice, the gear motor and condenserfan motor are energized. One minute later, the compressorstarts. As the refrigeration systems cools the water in theevaporator, ice will start to form within 2 to 5 minutes. Thisdepends on the inlet water temperature and ambient condi-tions. Ice production will continue until the bin control issatisfied (opens). The shut down process is very simple.On the F-450, F-800, F-1000, and F-2000 units, the entireunit shuts down within 6 seconds after the bin controlswitch opens. On the F-300 and F-500, approximately 90seconds after the bin control switch opens, the compres-sor stops, on minute later the gear motor and condenserfan motor stop. This sequence of operation is accom-plished through a series of timers within the solid statetimer board.

DCM SEQUENCE OF OPERATION
DCM sequence for the ice making unit is similar to the F-500, with a delay of the compressor at start up and a delayof the gear motor at shut down.
A periodic flush is also incorporated in the DCM units. AllDCM models have periodic agitation in the bin to eliminateice bridging. The DCM- 240 model uses a solid state relay toturn the gear motor for .2 seconds every 90 minutes. OnDCM-500 and 750 models, the solid state timer board willstart the agitation motor for .6 seconds every 12 secondsof accumulated dispensing time.
FLAKER/DCM PRODUCTION CHECK
Checking the production on a F/DCM is a simple process.To check the production you will need a bucket or pan tocatch the ice and a set of scales to weigh the ice. After theunit has operated for 10 to 20 minutes, catch the ice pro-duction for 10 full minutes. Weigh the ice to establish thebatch weight. Multiply the batch weight by 144 for the totalproduction in 24 hours. Some prefer to catch the ice for 20minutes and multiply the weight by 72 for a more realisticproduction check. It is true that a longer catch is moreaccurate, however, it doubles your test time and may onlyshow a 1 to 2% difference in production. Performing aproduction check is an excellent way to prove proper F/DCM operation.
FLAKER PERIODIC FLUSH
Beginning with the F-450M and larger flakers, a periodicflush cycle is included. A 12 hour timer will cycle the unitdown and open the flush valve which allows the completewater system to drain. The unit will remain off for 20 min-utes which allows any ice remaining in the evaporator tomelt and flush the evaporator walls and mechanical sealout. The inlet water valve is not energized during this flushperiod. The unit will automatically restart after 20 minuteson the flush timer.The F-500 will flush when the bin control is open.
