AArrttiiccllee IIII.. IINNSSTTAALLLLAATTIIOONN AANNDD SSTTAARRTT--UUPP

1) Outdoor Use: The Heat Exchanger is designed to be installed outdoors, but is suitable for installation indoors provided the space can dissipate the heat rejected from the Heat Exchanger.

2) Misuse: The Heat Exchanger has potential for misuse that could result in unplanned downtime. The main disconnect, drain and possibly field installed service valves can be operated by unauthorized personnel. If unauthorized is a concern then a security fence should be provided to reduce the potential for misuse. Fencing must not obstruct airflow and must leave room or be removable for service.

3) Leveling the Unit: Make sure unit is placed, on a flat, level, hard surface. Heat

Exchanger must be level or less than ½ inch of slope per 10 feet with the electrical box end of the Heat Exchanger at the high point. Use shims to correct level if needed. If a concrete slab is utilized, a 4 inch depth is adequate; pad should be at least 5 feet x 12 feet. If mounted on roof, two i-beams runners are typically provided to support feet at both ends. Heat Exchanger should be anchored from the feet mounting holes at the four corners of the machine. When mounted above office space, optional vibration mounting springs can be used to mount the Heat Exchanger, a spring mount will be provided for both ends of each foot.

4) Proper Spacing: The unit should be located where adequate air circulation is provided

with room for servicing. As a general guideline for units with vertical air discharge (fans located on top), keep the unit at least 5 feet away from walls and allow at least an 8 foot clearance above the unit.1 For units with horizontal air discharge (fans located on side), keep the side containing the fans a minimum of 15 feet from the wall. The side containing the filter should be a minimum of 6 feet from the wall. Avoid placing the Heat Exchanger under or near eves which may reflect the discharge air back into the air inlet2. Do not place in a poorly ventilated room. The build-up of high ambient temperatures can cause compressor and or machine damage3

CAUTION: Heat Exchanger must not be installed more than 65 feet above the heat exchangers and cryro compressor. The Heat Exchanger pumps can deliver up to 165 feet of head and the heat exchangers and cryro compressor are rated at 230 feet of head max. If the Heat Exchanger is mounted more than 65 feet above the heat exchangers and cryro compressor, the maximum allowable pressure on the heat exchangers and cryro compressor may be exceeded. Consult factory for installations requiring the Heat Exchanger to be installed more than 65 feet above the Heat Exchanger.

5) Connection of Water Piping: The material and nominal widths of the pipes must be

selected according to KOOLANT KOOLERS specifications. See dimensions in Article VII. Connect the fluid lines to the proper piping marked "FFLLUUIIDD IINNLLEETT TTOO HHEEAATT EEXXCCHHAANNGGEERR" and "FFLLUUIIDD OOUUTTLLEETT FFRROOMM HHEEAATT EEXXCCHHAANNGGEERR". Make sure that the flow of fluid to and from the unit can not be shut off or blocked while the Heat Exchanger is in operation, and the pipe size matches specifications.

1 Do not place in a mezzanine, near a ceiling or in an enclosed room without consulting factory. 2 Note: Placing Heat Exchanger under or near eves that can result in ice damage or damage to the eve as a result of hot air discharge. 3 If there is a concern about adequate ventilation for the Heat Exchanger please consult the factory.

2 P a g e 7

6) Length and Distance of Flow: The maximum equivalent linear feet of total piping which may be installed external to the Heat Exchanger is 500ft. using 2” plumbing.4 This is total piping which includes the feed and return to the heat exchangers and cryro compressor. The Heat Exchanger can pump fluid vertically up to 75 feet (usually 6 stories). Standard Fitting Losses in Equivalent Feet of Pipe 2inch 90º Standard Elbow: 05.0ft. loss 2inch 90º Street Elbow: 08.2ft. loss

2inch 45º Standard Elbow: 02.6ft. loss 2inch 45º Street Elbow: 04.5ft. loss 2inch Globe Valve: 55.0ft. loss 2inch Gate Valve: 02.3ft. loss 2inch Angle Valve: 24.0ft. loss

7) Voltage and Power: Check building power to ensure it matches the Heat Exchanger rated voltage and current. Voltage and circuit ampacity of the unit can be found on the data tag which is located on the front of the electrical panel or the electrical drawings. Connect power leads to main disconnect5.

8) Remote Display: If a remote display (Figure 1) is provided with the unit, install the

provided 150 foot communications cable between the Heat Exchanger electrical panel and the remote display location. For distances in excess of 150 feet, an optional Long Distance Remote Display kit is required6. See Initialization of Controller: section for remote display plug connection point on master controller.

Figure 1

Remote display and communication cable

CAUTION: Heat Exchangers installed with a crankcase heater require the electrical panel disconnect to be in the “ON” position for a minimum of 8 hours before start-up of unit. Leaving the Disconnect in the “ON” position maintains power to the compressor crankcase heater, preventing refrigerant migration and possible damage to system. Power can be off for 30 minutes for service without observing the 8 hour pre-heat requirement.

9) Units are shipped with refrigeration service valves in the open (back-seated) position and do not require any adjustments. Service valves should only be adjusted by a certified technician.

4 NOTE: If the equivalent piping exceeds 500’ please contact the factory for assistance. 1-800-968-5665 5 Wiring should match Heat Exchanger disconnect size and power requirements in accordance with local codes. 6 Contact the parts department if the distance to remote location exceeds 150ft.

10) Fill Unit: Fill the reservoir through the fill/sight glass. You will know it is properly

filled when water level remains between the two black level markers located on the sight glass.

CAUTION: Do not allow the fluid pumps to run dry. This will damage the pump seals and will not be covered under warranty.

11) Turn On Unit: Once Heat Exchanger reservoir has been filled, proceed to turn the main power disconnect on located on the electrical box door. Defeat the disconnect handle to open the electrical box door. Phase monitor light must be green and master controller alarms should be clear. Turn the system on. See the CCOONNTTRROOLLLLEERR OOPPEERRAATTIIOONN for more information on operation of the master controller.

Caution: Electrical Shock Hazard – Use appropriate personal protective equipment rated for exposure to 460 volts when within 3 feet of open electrical enclosure.

12) If pump motors do not start, check incoming power for correct sequence. If incoming

power is present, check any faults on the master controller. Reset any faults which may be present.

13) Proceed to run Heat Exchanger pump for five minutes or more to allow any air in the

system to be vented. Check fluid level after air is purged from the piping. Fill reservoir as needed.

14) Check controller for fault messages. Clear faults that may have occurred during start-

up procedure. If faults do not re-occur, the system is ready for continuous duty.

Section 3.02 Initialization of Controller: When the unit is first powered up after a download it goes through a self-test and requires a reboot after initialization. Cycle power to the controller if the message in Figure 4 is displayed. When the controller has finished its initial self test, the main page will be displayed. This displays the current time, date, unit #, fluid temperature, setpoint and system status. The page will look similar to Figure 5. Section 3.03 Starting the System: The system status displays the current status of the on/off switch. Turn the system on: Press the “Prg” key and the main menu will be displayed over three screens. Highlight the menu labeled “A. ON/OFF Unit” and press the “Enter” key.

The next page will look similar to Figure 6. Press the “Enter” key again, to move the cursor over the “SWITCH OFF”. Press the up arrow key to change the status to “SWITCH ON” Section 3.04 Enabling Devices: The pump and compressors can be individually enabled using the Enable/Disable function. To enable/disable devices press the “Prg” key to view the main menu. Highlight the menu labeled “G. SERVICE” and press the “Enter” key. Use the arrow keys to highlight the menu labeled “C. ENABLE/DISABLE” and press the “Enter” key again. The first page should display the Process Pumps similar to Figure 7. The three options for process pumps are:

Auto = Selects pump based on time and switches on flow alarm (if enabled) & overload alarm #1 = Selects only pump #1 to run #2 = Selects only pump #2 to run

Once the Process Pumps have been selected, press the “↓” arrow key to change the page to Circuit #1. To enable the compressor(s), use the “Enter” key and the arrow keys to change the status from “No” to “Yes”. Complete for any additional circuits on the unit. The number of compressors and circuits will depend on the design of the unit.

Section 3.05 Changing the Setpoint: To turn the system on press the “Prg” key and the main menu will be displayed. Highlight the menu labeled “B. SETPOINT” and press the “Enter” key. The page will look similar to Figure 8. Press the “Enter” key again, to move the cursor over the fluid setpoint temperature. Use the arrow keys to change the temperature and press the “Enter” key to accept. Press the “Esc” key to return back to the main menu.

Section 3.06 Viewing Alarms: When an alarm occurs the red alarm light on the PGD display will light up (a buzzer will activate if not disabled). To view this alarm, press the “Alarm” key and the alarms will be displayed. To view all active alarms, use the arrow keys to scroll up and down. To clear all inactive alarms, press and hold the “Alarm” key. At the end of the alarms a page similar to Figure 9 will be displayed. Press the “Enter” key and you will be taken to the Alarm Log page where you can view the alarm history. Section 3.07 Sequence of Operation: Upon system start, with all compressors and pumps enabled a brief delay will occur and then the pump that didn’t run during the last occurrence will start first. If flow is approved on either heat exchanger, the pump will continue to run. If no flow is established after a flow fault delay time, the opposing pump will automatically start. Pumps will rotate once every 24 hours to balance run time. Once flow is established and cooling demand increases to 25%, the compressor that hasn’t run in the longest period of time will start. As cooling demand increases to 50%, the compressor in the alternate compressor set that hasn’t run in the longest period of time will start. At a cooling demand of 75% and 100% the remaining compressors will stage up. When cooling demand decreases by 25% from a compressor start percentage, a compressor will cycle off, compressors drop out in a ‘first in-first out’ sequence. The cooling demand signal is proportional and integral driven so the cycling of compressors should slowly correct to be centered about set point.

Dimplex Thermal Solutions recommends that an inhibited ethylene glycol or inhibited propylene glycol solution be used in its Heat Exchangers. Inhibited glycol solutions will prevent rust in ferrous material systems and it will keep algae and bacteria from growing inside the system. Use 40-50% glycol for freeze protection. If low toxicity glycol is desired or required, use an inhibited propylene glycol7. CAUTION: Do not mix brand names or types of glycol as this may result in the inhibitors precipitating out of solution. Do not use automotive antifreeze in the Heat Exchanger unit as it can cause extensive damage to the cooling system. The use of automotive anti-freeze can affect the heat transfer of the system, fluid flow, and attack the pump seals. CAUTION: Galvanized piping is not recommended because the zinc will react with the inhibitor in the fluids, causing precipitate formation, depletion of the inhibitor package, and removal of the protective zinc coating, particularly above 100ºF. Precipitation can also lead to localized corrosion.

Dimplex Thermal Solutions offers its own brands of inhibited ethylene glycol called “K-Kool E” and inhibited propylene glycol “K-Kool P” as a service to its customers. Call 1-800-968-5665 (1-800-YOU-KOOL) and ask for the parts department for more information. If you have any other questions regarding the use of glycol or other water treatment issues for your Dimplex Thermal Solutions Heat Exchanger, please contact the factory at 1-800-968-5665 and ask for the service department.

7 Always refer to the original equipment manufacturers water quality treatment requirements to which the Heat Exchanger is connected before treating water.

2 P a g e 1 7

AArrttiiccllee VVII.. MMAAIINNTTEENNAANNCCEE The following maintenance procedures should be completed every 4 – 6 months:

Section 6.01 Condenser: Cleaning Air Filters and Condenser

In order for the refrigeration system to perform to its rated capacity, it is very important to keep the condensing temperature from getting too hot. This usually happens when the condenser is not kept properly cleaned. The air cooled condensers are supplied with cleanable aluminum air filters, and it is very important that they be cleaned as necessary to maintain good airflow. Failing to do so will result in poor unit performance and possible compressor damage.

To clean the filters use a brush, compressed air or wash out with water. To clean the condenser coil using compressed air, pressure must not exceed 30 psi. Blow air in the opposite direction of the air flow when Heat Exchanger is in operation.

Section 6.02 Electric Motors

Maintenance for electric motors is required only when these motors are furnished with grease fittings so they can be greased. If this is the situation, we recommend greasing every 6 months.

Section 6.03 Check Water Quality / Test Glycol Mixture

System fluid should be clean and free of contaminants. Check the inlet and outlet pressure on the unit for normal pressures. These can be found under the “HHEEAATT EEXXCCHHAANNGGEERR SSPPEECCIIFFIICCAATTIIOONNSS” section. Test the glycol concentration level to ensure levels are within the rated conditions. Refill tank as needed with pre-mixed glycol to maintain proper concentration.

Section 6.04 Inspect and Clean Fluid Strainer

Fluid Strainers protect the brazed plate heat exchangers from becoming clogged. Inspect and clean strainers after first hour of operation, after first week of operation, and annually thereafter.

2 P a g e 1 8

Section 6.05 Inspect Fluid System for Leaks or Loose Connection

Visually check fluid connections for any potential leaks in the system. Ensure there are no plumbing parts that show any significant wear including chaffing or cracking.

Section 6.06 Check All Wiring for Loose Connections, Chaffing or Damage

Turn off the main disconnect. Check all wiring inside of electrical panel and inside the Heat Exchanger unit for loose or damaged wires. Tighten any loose terminals and replace any damaged wires.

---------------------------------------------------------------------- HAZARDS IDENTIFICATION ---------------------------------------------------------------------- Potential Health Effects

Inhalation of high concentrations of vapor is harmful and may cause heart irregularities, unconsciousness, or death. Intentional misuse or deliberate inhalation may cause death without warning. Vapor reduces oxygen available for breathing and is heavier than air. Liquid contact can cause frostbite.

6037FR DuPont Page 2 Material Safety Data Sheet

(HAZARDS IDENTIFICATION - Continued)

HUMAN HEALTH EFFECTS:

Overexposure to the vapors by inhalation may include temporary nervous system depression with anesthetic effects such as dizziness, headache, confusion, incoordination, and loss of consciousness. Higher exposures to the vapors may cause temporary alteration of the heart’s electrical activity with irregular pulse, palpitations, or inadequate circulation. Gross overexposure may be fatal. Skin contact with the liquid may cause frostbite.

Individuals with preexisting diseases of the central nervous or cardiovascular system may have increased susceptibility to the toxicity of increased exposures.

Carcinogenicity Information

None of the components present in this material at concentrations equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH as a carcinogen.

---------------------------------------------------------------------- FIRST AID MEASURES ---------------------------------------------------------------------- First Aid

INHALATION

If inhaled, immediately remove to fresh air. Keep person calm. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician.

SKIN CONTACT

Flush area with lukewarm water. Do not use hot water. If frostbite has occurred, call a physician.

EYE CONTACT

In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Call a physician.

INGESTION

Not a probable route. However, in case of accidental ingestion, call a physician.

Notes to Physicians

THIS MATERIAL MAY MAKE THE HEART MORE SUSCEPTIBLE TO ARRHYTHMIAS. Catecholamines such as adrenaline, and other compounds having similar effects, should be reserved for emergencies and then used only with special caution.

6037FR DuPont Page 3 Material Safety Data Sheet

---------------------------------------------------------------------- FIRE FIGHTING MEASURES ---------------------------------------------------------------------- # Flammable Properties

Flash Point : No flash point

Flammable Limits in Air, % by Volume: LEL : None per ASTM E681 UEL : None per ASTM E681 Autoignition: Not determined

Fire and Explosion Hazards:

Cylinders may rupture under fire conditions. Decomposition may occur.

Contact of welding or soldering torch flame with high concentrations of refrigerant can result in visible changes in the size and color of torch flames. This flame effect will only occur in concentrations of product well above the recommended exposure limit, therefore stop all work and ventilate to disperse refrigerant vapors from the work area before using any open flames.

R-407C is not flammable in air at temperatures up to 100 deg C (212 deg F) at atmospheric pressure. However, mixtures of R-407C with high concentrations of air at elevated pressure and/or temperature can become combustible in the presence of an ignition source. R-407C can also become combustible in an oxygen enriched environment (oxygen concentrations greater than that in air). Whether a mixture containing R-407C and air, or R-407C in an oxygen enriched atmosphere becomes combustible depends on the inter-relationship of 1) the temperature 2) the pressure, and 3) the proportion of oxygen in the mixture. In general, R-407C should not be allowed to exist with air above atmospheric pressure or at high temperatures; or in an oxygen enriched environment. For example: R-407C should NOT be mixed with air under pressure for leak testing or other purposes.

Experimental data have also been reported which indicate combustibility of HFC-134a, a component in this blend, in the presence of chlorine.

Extinguishing Media

As appropriate for combustibles in area.

Fire Fighting Instructions

Cool cylinder with water spray or fog. Self-contained breathing apparatus (SCBA) is required if cylinders rupture and contents are released under fire conditions. Water runoff should be contained and neutralized prior to release.

6037FR DuPont Page 4 Material Safety Data Sheet

---------------------------------------------------------------------- ACCIDENTAL RELEASE MEASURES ---------------------------------------------------------------------- Safeguards (Personnel)

NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL) sections before proceeding with clean-up. Use appropriate PERSONAL PROTECTIVE EQUIPMENT during clean-up.

Accidental Release Measures

Ventilate area, especially low or enclosed places where heavy vapors might collect. Remove open flames. Use self-contained breathing apparatus (SCBA) for large spills or releases.

---------------------------------------------------------------------- HANDLING AND STORAGE ---------------------------------------------------------------------- Handling (Personnel)

Avoid breathing vapor. Avoid liquid contact with eyes and skin. Use with sufficient ventilation to keep employee exposure below recommended limits. Contact with chlorine or other strong oxidizing agents should also be avoided. See Fire and Explosion Data section.

Storage

Clean, dry area. Do not heat above 52 deg C (125 deg F).

---------------------------------------------------------------------- EXPOSURE CONTROLS/PERSONAL PROTECTION ---------------------------------------------------------------------- Engineering Controls

Avoid breathing vapors. Avoid contact with skin or eyes. Use with sufficient ventilation to keep employee exposure below the recommended exposure limit. Local exhaust should be used if large amounts are released. Mechanical ventilation should be used in low or enclosed places.

Personal Protective Equipment

Impervious gloves should be used to avoid prolonged or repeated exposure. Chemical splash goggles should be available for use as needed to prevent eye contact. Under normal manufacturing conditions, no respiratory protection is required when using this product. Self-contained breathing apparatus (SCBA) is required if a large release occurs.

P266 Series Single-Phase Condenser Fan Speed Control Installation Instructions 1

Application

The P266 Single-Phase Condenser Fan Speed Control is a cost-effective, compact, weather-resistant, and durable speed control for single-phase, PSC motors used in a wide variety of low-ambient refrigeration and air conditioning condenser applications.

The P266 fan speed controls are designed to replace the Johnson Controls® P66 Series and P215 Series Fan Speed Controls and provide additional features and application flexibility.

MountingLocation and Mounting ConsiderationsObserve these guidelines when locating and mounting a P266 fan speed control:

• Ensure that the mounting surface and mounting hardware can support the control and wiring.

• Mount the P266 control upright on a vertical surface with the heat sink fins oriented vertically and the conduit/electrical holes facing down.

• Ensure that air can flow through the heat sink fins and provide 10 cm (4 in.) minimum clearance around the heat sink.

• Mount the P266 control in a location away from sources of excessive heat and within the specified ambient operating conditions. See Technical Specifications for ambient operating conditions.

IMPORTANT: Use this P266 Single-Phase Condenser Fan Speed Control only as an operating control. Where failure or malfunction of the P266 fan speed control could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the P266 fan speed control.

!CAUTION: Risk of Property DamageUse only single-phase Permanent Split Capacitor (PSC) motors approved by the manufacturer for speed control application with the P266 control. Failure to use a single-phase PSC motor may damage the motor and other property.

Issued April 29, 2009Supersedes January 21, 2009

P266 Series Single-Phase Condenser Fan Speed Control Installation Instructions2

Wiring Refer to the model-specific wiring diagram located on the interior label of the P266 control and observe these guidelines when wiring the P266 fan speed control:

• Ensure that the wires between the P266 control and the fan motor do not exceed 15 m (50 ft).

• Wires connected to the line-voltage terminal block must be 3.31 mm2 (12 AWG) or smaller.

• Low-voltage wires must be less than 30 m (100 ft).

!WARNING: Risk of Electric Shock.Disconnect each of multiple power supplies before making electrical connections. More than one disconnect may be required to completely de-energize equipment. Contact with components carrying hazardous voltage can cause electric shock and may result in severe personal injury or death.

IMPORTANT: Do not connect supply power to the P266 fan speed control before finishing wiring and checking all wiring connections. Short circuits or improperly connected wires can result in damage to the P266 control and void any warranty.

IMPORTANT: Do not exceed the P266 fan speed control electrical ratings. Exceeding P266 control electrical ratings can result in permanent damage to the P266 control and void any warranty.

IMPORTANT: Use copper conductors only. Make all wiring in accordance with local, national, and regional regulations.

IMPORTANT: Electrostatic discharge can damage P266 control components. Use proper Electrostatic Discharge (ESD) precautions during installation and servicing to avoid damaging P266 components.

P266 Series Single-Phase Condenser Fan Speed Control Installation Instructions4

Setup and AdjustmentsAll P266 controls ship with factory-set default values and mode settings. In most applications, the default values and modes do not require field adjustment.

If your P266 control application requires you to change the value or mode settings, you must:

1. Calculate the new values and determine the new mode settings required for your application. (See P266 Control Values and Modes.)

2. Change the existing settings on the control to the new values and modes using the P266 control setup interface. (See Setting Values and Modes.)

P266 Control Setup InterfaceThe P266 control setup interface consists of a DIP switch block with eight binary switches, a push button switch, and a green Light-Emitting Diode (LED) (Figure 2). You can change the factory-set default values and modes by repositioning the DIP switches and saving the new settings. The number of LED flashes (in sequence) indicates which value and/or modes that you are saving. See Table 2 for more information about LED flash sequences, values, and modes.

During normal operation, the green LED is On/lit constantly. When you press and hold the push button, the LED goes Off for 3 seconds then flashes two times. The LED then goes Off again for 3 seconds and flashes three times, and continues this pattern until seven flashes or until you release the push button.

Each sequence of flashes indicates a value or a value and set of mode settings. Releasing the push button after the desired flash sequence saves the value and/or modes that are currently set on the DIP switch block. See Table 2 for more information.

P266 Control Values and ModesP266 controls have up to ten values and modes (in six flash sequences) that can be changed in the field. See Table 2 for more information about flash sequences and the associated values and modes.

Start Voltage ValueThe start voltage (VAC) is the voltage delivered by the P266 control to the fan motor to run the motor at minimum speed in your application.

The Start Voltage value is a percentage of the P266 control’s input voltage. Use the following formula to calculate the Start Voltage value for your application.

Low Pressure ModeLow Pressure Mode determines whether the fan motor is either On (at start voltage/minimum speed) or Off when the sensed pressure at the P266 transducer is below the start pressure setpoint.

Start Pressure ValueStart pressure (psi or bar) is the pressure setpoint at which the P266 control outputs the start voltage and runs the fan motor at minimum speed. Start Pressure value is a function of the start pressure setpoint and the pressure range of the referenced P266 transducer. Use the following formula to calculate the Start Pressure value. See Table 3 for P266 transducer pressure ranges.

End Pressure ValueThe end pressure setpoint is the pressure (bar or psi) at which the P266 control outputs the End Voltage and runs the fan motor at maximum speed. End Pressure value is a function of the end pressure setpoint and the total pressure range of the referenced transducer. Use the following formula to determine your application End Pressure value. See Table 3 for P266 transducer pressure ranges.

Split Winding ModeSome single-phase PSC motors have split motor winding wire leads. Setting the Split Winding mode On enables the M2 Triac to provide voltage to the main windings (and not the auxiliary windings), which increases motor efficiency (Figure 3A and Figure 4A).

Note: Split Winding mode is available for only 240 VAC single-phase PSC motors that have split winding wire leads. Refer to the motor manufacturer’s installation instructions to determine if your fan motor may be wired to enabled the Split Winding mode.

End Voltage ModeEnd voltage is the voltage output by the P266 control (as a percentage of the full voltage) that is maintained when the monitored pressure is equal to or greater than the End Pressure. The End Voltage mode can be set to either 95% or 97% of the total input voltage.

Low-Speed Capacitor ModeIn some fan speed applications, a (user-supplied) Low-speed capacitor (LSC) can be connected to the P266 control’s M3 triac and the controlled fan motor (Figure 3 and Figure 4). The low-speed capacitor is enabled at low voltages to enhance the fan motor efficiency and performance. Set Low-speed Capacitor mode On when a low-speed capacitor is used.

Note: The optional low-speed capacitor should be equal in both the voltage range and the microfarad value to the auxiliary capacitor supplied by the manufacturer, but the capacitor must not exceed 15 microfarads.

Note: You must also set the Changeover Voltage value when a low-speed capacitor is used in your P266 control application. See Changeover Voltage Value and Determining Changeover Voltage Value for more information on setting the Changeover Voltage value.

P266 Series Single-Phase Condenser Fan Speed Control Installation Instructions6

Auxiliary Fan Stage ModeYou can set the P266 fan speed control to cycle (On/Off) up to three additional (fixed-speed) fan motors or fan stages in conjunction with the variable speed fan controlled by the P266 control.

Three low-voltage circuits (Figure 2) can be wired to control the auxiliary fan motor/stage starters. See Table 2 for information on setting the number of auxiliary fans used in your application.

Figure 7 shows a P266 control application with one auxiliary fan operating in conjunction with the speed-controlled fan. When the condenser load exceeds the output capacity of the speed-controlled fan, the P266 control powers On the auxiliary fan and shifts the speed-controlled (P266) fan to a new start pressure.

Auxiliary Fan Overlap ValueAuxiliary Fan Overlap value determines the pressure range overlap (as a percentage of the total pressure [throttling] range) between the fan stages set up on the P266 control. The fan overlap value is equal for all auxiliary fan stages set up on the control.

Increasing the Auxiliary Fan Overlap value decreases the (On/Off) cycling rate of the auxiliary fans and increases the pressure differential between auxiliary fan stages (which increases the pressure range of each auxiliary fan stage).

Note: If the P266 control is set for no auxiliary fans, the Auxiliary Fan Overlap value is not used. See Table 2 for information on setting the number of auxiliary fans used in your application.

Changeover Voltage ValueThe Changeover Voltage value determines the voltage at which the P266 control enables and disables the M3 triac and the low-speed capacitor (Figure 6). See Determining Changeover Voltage Value.

Setting Values and ModesTo change settings and values on a P266 control:

1. Determine the operating pressure setpoints (psi or bar), voltage inputs and outputs (VAC), and the other modes of operation required for your condenser fan motor control application.

2. Convert the selected pressure setpoints (psi or bar) and voltage targets (VAC) into P266 control values. See P266 Control Values and Modes and Table 2.

3. Position the DIP switches to set the new values and/or modes. See Setting up the DIP Switch Block.

4. Press and hold the push button until the number of LED flashes indicates the desired value or set of values and/or mode settings. Release the push button after:• two flashes to save the Low Pressure mode

setting and the Start Voltage value

• three flashes to save the Start Pressure value

• four flashes to save the End Pressure value

• five flashes to save the Split Winding, End Voltage, Low-speed Capacitor Mode, and Auxiliary Fan Stages mode settings

• six flashes to save the Auxiliary Fan Overlap value

• seven flashes to save the Changeover Voltage value

Note: See Table 2 for more information about the values and modes that are associated with the number of LED flashes.

5. Repeat Steps 3 and 4 for the next value and/or mode you need to change.

6. After you save all of the new values and mode settings, set all of the DIP switches to the On position to lock out the push button operation.

P266 Series Single-Phase Condenser Fan Speed Control Installation Instructions 7

Setting up the DIP Switch BlockTo set new values and modes on the DIP switch block:

1. Position all of the switches on the DIP switch block to the Off position.

2. Position the numbered switches to ON so that the total of the switch numbers (in the ON position) equals the desired setup value. Start with the highest number switch that is less than the setup value. (For example, if the desired setup value is 185, position switch 128 to ON first. Then position switch 32 ON, followed by switch 16, switch 8, and switch 1 [128+32+16+8+1=185] [Figure 8]).

Mode settings require you to position only one or two switches on the DIP switch block, depending on the mode. See Table 2 for more information about the values and modes that are associated with the number of LED flashes.

Test Voltage ModeTest Voltage mode is a setup and diagnostic tool in the P266 control firmware that allows you to test a condenser fan motor’s operation at different voltage values in the field and determine the optimal Start Voltage value for your P266 control application.

Test Voltage mode also allows you to determine and set the optimal Changeover Voltage value for the M3 triac in P266 control applications that use a low-speed capacitor.

To use the Test Voltage Mode, you need:

• a P266 control model designed for your condenser fan application

• access to the condenser (and fan motor) controlled by your P266 control

• a clamp-on ampere meter with 15 A range (to check changeover current draw when determining Changeover Voltage value)

• an insulated probe to hold down the push-button and change the DIP switch positions

• a 24 VAC Class 2 power supply (only for P266 control models that require an external 24 VAC power supply)

• a Low-Speed Capacitor (LSC), sized for the fan motor (only for P266 control applications that use a low-speed capacitor)

Note: The LSC should be equal in both the voltage range and the microfarad value to the motor manufacturer’s auxiliary capacitor, but the LSC must not exceed 15 microfarads.

Setting up Test Voltage ModeBefore you power on a P266 control and enable the Test Voltage mode on the control:

1. Read and follow the guidelines and procedures in the Mounting and Wiring sections.

2. Mount and wire the P266 control in your condenser application and observe these additional guidelines:

• Refer to the label inside the P266 control housing cover for model-specific wiring details. See Wiring for some wiring options.

• Wire the auxiliary and main windings according to the motor manufacturer’s instructions and your application requirements. Split the windings (at the winding leads) and power them separately, if your application and motor allow for split-winding operation. See Figure 3 and Figure 4.

IMPORTANT: All of the switches on the DIP switch block must be set to the proper positions for your application before you press and release the push button to save the values and/or mode settings. See Table 2 for more information on switch positions.

P266 Series Single-Phase Condenser Fan Speed Control Installation Instructions8

• If your application uses an optional low-speed capacitor, wire the LSC to the M3 triac and motor only after you have checked and recorded the current draw at maximum. See Determining Changeover Voltage Value.

• If your P266 control model requires an external 24 VAC power supply for control operation, wire that power supply to the control. (Refer to the wiring label inside the P266 control cover for external power supply requirements.)

• You do not have to connect, wire, or power the P266 transducer, or put a load on the condenser to operate a P266 control in the Test Voltage mode. Test Voltage mode allows you to use the DIP switch to set the voltage supplied to the motor by the P266 control.

3. Set up the P266 control and the condenser fan motor for the intended operation, by setting the required values and modes of operation for your condenser fan application. See Setup and Adjustments for procedures.

Determining Changeover Voltage ValueIn the Test Voltage mode, you can determine and set the Changeover Voltage value for P266 control applications that use an optional low-voltage capacitor. To determine and set the Changeover Voltage value:

1. Mount, wire, and set up the P266 control and the condenser fan motor for operation in the Test Voltage mode. See Setting up Test Voltage Mode.

Note: Do not wire the low-speed capacitor until Step 5 of this procedure.

2. Set all of the DIP switches except switch 1 to the ON position; set switch 1 to Off.

3. Apply line-voltage power to the P266 control (and the external 24 VAC power supply on required models), then, within the first 30 seconds after applying power, press and release the push button three times. The LED goes off and stays off, and the fan motor accelerates to maximum speed (at 95 or 97% of maximum voltage) and stays at the maximum voltage for up to 5 minutes.

4. At maximum voltage, use the clamp-on ampere meter to check the current draw (in amperes) of the fan motor auxiliary windings and record the auxiliary windings current draw for the motor at maximum voltage.

5. Disconnect line-voltage power to the P266 (andthe external 24 VAC power supply on required models).

6. Wire the low-speed capacitor to the M3 triac and the motor auxiliary windings. (See Figure 3 and Figure 4 for M3 triac wiring options.)

7. Set all of the DIP switches except switches 8 and 32 to the Off position; set switches 8 and 32 to the ON position. (8 + 32 = 40% of maximum voltage value.)

8. Apply line-voltage power to the P266 control (and the external 24 VAC power supply on required models), then, within the first 30 seconds after applying power, press and release the push button three times. The LED goes off and stays off, and the fan motor accelerates to the speed at 40% of the maximum voltage (for up to 5 minutes).

9. At 40% of maximum voltage, use the clamp-on ampere meter to check the current draw (in amperes) of the low-speed capacitor lead connected to the M3 terminal and record the current draw for the low-speed capacitor lead at 40% voltage.

10. Repeat Step 7 but increase the percent voltage value by 8%, then repeat Step 8, Step 9, and Step 10 at the increased voltage values until the current draw equals the (maximum voltage) current draw recorded in Step 4.

Note: If the motor stops or does not run smoothly, reduce the voltage value on the DIP switches by 4% and test the motor operation.

11. The DIP switch voltage value is now equal to the highest voltage of the low-speed mode or the Changeover Voltage value.

12. Press and hold the push button until the LED flashes 3 time, then release the button. The Changeover Voltage value is set and saved on the P266 control.

Note: If you want to also determine and set the Start Voltage value for your P266 control and motor, you can go directly to Step 3 of the Determining Start Voltage Value procedure.

13. Disconnect power to the P266 control and set all of the DIP switches to the On position to lock out the push button operation.

14. Reconnect power to the P266 control to resume normal motor speed control.

P266 Series Single-Phase Condenser Fan Speed Control Installation Instructions 9

Determining Start Voltage ValueIn the Test Voltage mode, you can also determine and set the Start Voltage value on for P266 control application.

To determine and set the Start Voltage value:

1. Mount, wire, and set up the P266 control and the condenser fan motor for operation in the Test Voltage mode. See Setting up Test Voltage Mode.

Note: If your application uses Split Winding mode and Low Speed Capacitor mode, wire the split windings and low-speed capacitor according to your application requirements (Figure 3A and Figure 4A).

2. Apply line-voltage power to the P266 control (and the external 24 VAC power supply on required models), then, within the first 30 seconds after applying power, press and release the push button three times. The LED goes off and stays off.

3. Position the DIP switches so that the total value of the switches positioned ON is equal to a percentage value equal to or slightly higher than your estimated Start Voltage value. (For example, if you estimate the start voltage of the motor to be 25% of the total voltage, position switches 16, 8, 4, and 2 ON. 16 + 8 + 4 + 2 = 30%, which is slightly higher than your 25% estimate.) The fan motor accelerates to the speed at 30% of maximum voltage and stays at that speed.

4. Observe the fan motor operation and determine if the applied start voltage runs the motor at the desired start speed:

• If the start speed and motor operation meet your application requirements, go to Step 5.

• If the start speed or operation does not meet your application requirements, return to Step 3 and set a new estimated Start Voltage value to generate the desired motor start speed.

5. When your motor is running at the desired start speed (Start Voltage value), press and hold the push button until the LED flashes 2 times in succession, then release the push button. The Start Voltage value is set and saved on the P266 control.

6. Disconnect power to the P266 control and set all of the DIP switches to the On position to lock out the push button operation.

7. Reconnect power to the P266 control to resume normal motor speed control.

FlowFlow

• There are no minimum straight-piping requirements for the inlet or the outlet.

• Valves may be installed in horizontal or vertical lines.The vertical flow can be up or down.

• The flow arrow on the valve body must be pointing inthe direction of flow.

• Avoid placing the valve close to a pump discharge.Allow 10’ before the valve if possible.

• The model number gives the following information:body style, line size, end connections, P/T ports, GPM flow settings.

Flange and Groove Body ProductsMost flange products are not furnished with flange gasketsor bolts, and unless specified otherwise have 150# raised-face flanges. Standard installation techniques coveringflanged products should be followed. All products have aflow direction arrow. Care must be taken to locate thevalve so that the arrow is pointed in the direction of theflow.

Grooved end products are to be installed using a “Victaulic-style coupling”. The same installation techniques used toinstall standard “Victaulic” products should be followed.Care must be taken to assure the flow direction arrow is inthe proper location.

Installation

Wafer Body Valves (Model WB, WG, WR, WS, WT)1. Make sure the long bolts and nuts to secure the

wafer body are included with the valve.

2. Install the wafer body between 150# or 300# flanges making sure the flow arrow is in the direction of flow.

3. Make sure the inside diameter of the customer-suppliedgaskets does not interfere with the flow.

4. The pressure or P/T ports should be vertical up. Theseports can be used to vent air from each side of the bodyafter filling and start-up.

GeneralFlow control valves are purchased for a specific GPM flowrate and are equipped with a spring-loaded piston to main-tain that flow rate. Five spring ranges are available forAutoFlow valves. The first number is the differential pres-sure (psi) needed to achieve the GPM rating. The secondnumber is the maximum D.P. where the rated GPM will bemaintained. The model number will show the spring rangeof the product.

Example:Model XX (-)

(-) can be L = 2-32, H = 5-60 or 1 (2-32), 2 (5-60), 3 (3-20),4 (5-40), 5 (7-45)

Verifying FlowThe flow can be verified by measuring the DP (differentialpressure) across the valve using the portsprovided. If itmeasures between 2-32 (or other) the flow is usually in thespecified flow range. Debris plugging one of the flow portswill cause the DP to read high, so make sure the unit isclean when verifying flow. There are several ways to mea-sure DP:

a. A pressure gauge with a P/T adapter can measurethe pressure on each side of the valve. The differencesbetween these readings is the DP.

b. A differential pressure gauge can simultaneously measure from each port and read the DP directly.

Using a StrainerA Y-strainer is recommended to prevent clogging. A 40-mesh screen is recommended for flows 1.5 GPM or less.

AccuracyAccuracy is rated at 5% of the specified flow rate. Accuracywill vary with the temperature of the incoming fluid and spe-cific gravity of the fluid. Rated flow rates are suitable for gly-col solutions up to 50 percent.

Air PurgeAutoFlow valves will not work properly if air is trapped in thehousing. Models with wafer bodies will always have a smallamount of air because its body is higher than the top of thepipe. Air can cause a clicking noise in some valves.

Air can easily be vented using the pressure or PT ports. Onsmall valves, 2” and under, the upstream port can be used.On larger steel valves, both ports should be purgedbecause air can reside on both sides of the mid-plate. Asimple way to purge air with PT ports is to use a 1/4” manu-al air vent (Model AV) with a long gauge adapter (ModelGA30).

• There is no maintenance required on Flow Control valves.

• If inlet strainers are used they should be inspected andcleaned after start-up and every six months thereafter.

• The controlled flow rate can be changed in the field, on1/2” - 2 1/2” AC, KY & YR Models, by replacing the car-tridge assembly in the control valve. This requires

removing the cartridge from the controller. Specificinstructions for making the change come with new car-tridge assemblies. The change takes only 5 to 15 min-utes with ordinary tools. Changing cartridges on largervalves should be done at the factory.

Call for an RMA number before returning equipment to thefactory.

Troubleshooting Guide

Possible Cause Possible Solution

• PROBLEM: Low Water Flow

1) Strainer clogged 1) Back-flush or manually clean the coil strainer.

2) Wrong location 2) Make sure the valve is in the proper location with the correct GPM.

3) Low system pressure 3) If possible, check the pressure at the hook-up supply and return valves. The drop through the coil and ATC valve may be too large for the available head.

4) Balance valve plugged 4) The AutoFlow valve may have debris. Remove cartridge, clean and replace.

5) ATC valve port closed or wrong Cv 5) Make sure the ATC is wide open and has proper Cv.

6) System valve is partially closed 6) Open all manual system valves.

• PROBLEM: High Water Flow

1) Wrong location 1) Make sure the valve is in the proper location with the correct GPM.

2) System pressure too high 2) Check the differential pressure across the AutoFlow valve. If larger then 32 psi, close the return-side ball valve until the difference is lessthen 32 psi. The spring range on the cartridge could be changed to 5-60psi which will also solve the problem.

3) AutoFlow valve backward 3) Check the flow arrow and reverse valve if necessary.

• PROBLEM: Noise or Vibration

1) AutoFlow valve clicking or noisy a) Check the Delta P across the AutoFlow valve. If at or near themaximum, it may be necessary to replace the cartridge with a differentspring range.

b) Make sure the air is purged from the system. Air can cause a clickingnoise. WS valves require air purging on each side of the mid-plate.

c) Two AutoFlow valves close coupled in series can cause pulsing.
