Cooler and condenser shells are separatedat tube sheets and are not skidded. Refrig-erant lines between shells are flanged andcapped, requiring no welding.

All wiring integral with compressor is left onit. All wiring harnesses on shells are removed.All openings on compressor and shells areclosed and charged with dry nitrogen (2 to 3psig)(13.8 to 21 kPa).

Miscellaneous packaging of control center,tubing, water temperature controls, wiring,oil, isolators, solid state starter (option), etc.;refrigerant charge shipped separately.

NOTE: Units shipped dismantled MUST be re-assembled by, or under the supervision of, aYORK representative. (See Form 160.49-N3).

When more than one CODEPAK is involved, the majorparts of each unit will be marked to prevent mixing ofassemblies. (Piping and Wiring Drawings to be furnishedby YORK.)

INSPECTION – DAMAGE – SHORTAGE

The unit shipment should be checked on arrival to seethat all major pieces, boxes and crates are received.Each unit should be checked on the trailer or rail carwhen received, before unloading, for any visible signsof damage. Any damage or signs of possible damagemust be reported to the transportation company imme-diately for their inspection.

YORK WILL NOT BE RESPONSIBLE FOR ANY DAM-AGE IN SHIPMENT OR AT JOB SITE OR LOSS OFPARTS. (Refer to Shipping Damage Claims, Form50.15-NM).

When received at the job site all containers should beopened and contents checked against the packing list.Any material shortage should be reported to YORK im-mediately. (Refer to Shipping Damage Claims, Form50.15-NM.)

CODEPAK DATA PLATE

A unit data plate is mounted on the control center as-sembly of each unit, giving unit model number; designworking pressure; water passes; refrigerant charge;serial numbers; and motor power characteristics andconnection diagrams.

Additional information may be found on the motor dateplate. This information should be included when con-tacting the factory on any problem relating to the motor.

RIGGING

The complete standard CODEPAK is shipped withoutskids. (When optional skids are used it may be neces-sary to remove the skids so riggers skates can be usedunder the unit end sheets to reduce overall height.)

Each unit has four (4) lifting holes (two on each end) inthe end sheets which should be used to lift the unit.(See Fig. 5.)

Care should be taken at all times during rigging andhandling of the CODEPAK to avoid damage to the unitand its external connections. Lift only using holes shownin Fig. 5.

Do not lift the unit with slings around motor/com-pressor assembly or by means of eyebolts in thetapped holes of the compressor motor assembly.Do not turn a unit on its side for rigging. Do not rigby one end.

Use of Slings (See Fig. 5 for proper use of slings inrigging.)

CAUTION : If necessary to rig the CODEPAK by one endto permit lifting or dropping through a verti-cal passageway, such as an elevator shaft,contact YORK factory shipping for specialrigging instructions.

The rigging and operating weights and overall dimen-sions are given on pages 6 thru 13 as a guide in deter-mining the clearances required for rigging. (Add 6" (153mm) to overall-height for optional skidded unit.)

RIGGING UNIT TO FINAL LOCATION

Rig the unit to its final location on the floor or mountingpad, lift the unit (or shell assembly) by means of an over-head lift and lower the unit to its mounting position. (Ifoptional shipping skids are used remove them beforelowering the CODEPAK to its mounting position.)

NOTE: At this point units shipped dismantled shouldbe assembled under the supervision of a YORKrepresentative.

If cooler is to be field insulated, the insulation should beapplied to the cooler before the unit is placed in positionwhile the unit is in the lift position. Be sure unit is prop-erly supported. (See INSULATION, page 24.)

LOCATING AND INSTALLING ISOLATORPADS (REFER TO FIG. 6)

The isolator pad mounts are to be located as shown inFig. 6.

After the isolator pads have been placed into positionon the floor, lower the CODEPAK onto the pads. Whenthe unit is in place remove the rigging equipment andcheck that the unit is level both longitudinally and trans-versely. The unit should be level within 1/4" (6.4 mm)from one end to the other end and from front to the rear.If the chiller is not level within the amount specified, liftit and place shims between the isolation pad and theCODEPAK tube sheets. (Shims furnished by the in-staller.) Lower unit again and recheck to see that it islevel.

CHECKING THE ISOLATION PAD DEFLECTION

All isolation pads should be checked for the properdeflection while checking the level of the CODEPAK.Each pad should be deflected approximately 0.15 inch(3.8 mm). If an isolation pad is under deflected, shimsshould be placed between the unit tube sheet and thetop of the pad to equally deflect all pads.

LEVELING THE UNIT

The longitudinal alignment of the unit should be checkedby placing a level on the top center of the cooler shellunder the compressor/motor assembly. Transverse align-ment should be checked by placing a level on top of theshell end sheets at each end of the CODEPAK.

INSTALLING OPTIONAL SPRING ISOLATORS (RE-FER TO FIG. 7)

When ordered, 4 spring type isolator assemblies will befurnished with the unit. The 4 assemblies are identicaland can be placed at any of the 4 corners of the unit.

While the unit is still suspended by the rigging, the isola-tors should be bolted to the unit by inserting the cap

screw(s) through the hole(s) in the mounting bracketinto the tapped hole in the top of the isolator levelingbolt(s). Then the unit can be lowered onto the floor.

The leveling bolts should now be rotated one (1) turn ata time, in sequence, until the unit end sheets are about1-3/4" (44.4 mm) off the floor or foundation, and the unitis level. Check that the unit is level, both longitudinallyand transversely (see Leveling The Unit). If the levelingbolts are not long enough to level unit due to an unevenor sloping floor or foundation, steel shims (grouted, ifnecessary) must be added beneath the isolator assem-blies as necessary.

After the unit is leveled, wedge and shim under eachcorner to solidly support the unit in this position whilepiping connections are being made, pipe hangers ad-justed and connections checked for alignment. Then theunit is filled with water and checked for leaks. The level-ing bolts should now be finally adjusted until the wedgesand shims can be removed. The unit should now be incorrect level position, clear of the floor or foundationand without any effect from the weight of the piping.When the unit is properly supported, spring isolator in-stalled height will be 6" to 6-1/4" (152-159 mm).

PIPING CONNECTIONS

After the unit is leveled (and wedged in place for optionalspring isolators) the piping connections may be madeup; chilled water, condenser water and refrigerant relief.The piping should be arranged with offsets for flexibility,and adequately supported and braced independently ofthe unit to avoid strain on the unit and vibration transmis-sion. Hangers must allow for alignment of pipe. Isolators(by others) in the piping and hangers are highly desir-able, and may be required by specifications, in order toeffectively utilize the vibration isolation characteristics ofthe vibration isolation mounts of the unit.

Check for piping alignment – Upon completion of pip-ing, a connection in each line as close to the unit aspossible should be opened, by removing the flange boltsor coupling and checked for piping alignment. If any ofthe bolts are bound in their holes, or if the connectionsprings out of alignment, the misalignment must be cor-rected by properly supporting the piping or by applyingheat to anneal the pipe.

NOTE: If the piping is annealed to relieve stress, theinside of the pipe must be cleaned of scale be-fore it is finally bolted in place.

COOLER AND CONDENSER WATER PIPING

The cooler and condenser liquid heads of CODEPAK unitshave nozzles which are grooved, suitable for welding 150psig DWP flanges or the use of Victaulic couplings.

INSTALLATION


FIG. 8 – SCHEMATIC OF A TYPICAL PIPING ARRANGEMENT FOR COOLING ONLY CODEPAKS

The nozzles and water pass arrangements are furnishedin accordance with the job requirements (see ProductDrawings as referenced in Table 4) furnished with thejob. Standard units are designed for 150 psig (1034 kPa)DWP on the water side. If job requirements are forgreater than 150 psig (1034 kPa) DWP, check the unitdata plate before applying pressure to cooler or con-denser to determine if the CODEPAK has provisions forthe required DWP.

Inlet and outlet connections are identified by labelsplaced adjacent to each nozzle.

Cooling Units – Chilled Water

Foreign objects which could lodge in, or block flowthrough, the cooler and condenser tubes must be keptout of the water circuit. All water piping must be cleanedor flushed before being connected to the CODEPAK,pumps, or other equipment.

Permanent strainers (by others) are required in boththe cooler and condenser water circuits to protect theCODEPAK as well as the pumps, tower spray nozzles,chilled water coils and controls, etc. The strainer shouldbe installed in the entering chilled water line, directlyup-stream of the CODEPAK.

Water piping circuits should be arranged so that thepumps discharge through the CODEPAK, and shouldbe controlled as necessary to maintain essentially con-stant chilled and condenser water flows through the unitat all load conditions.

If pumps discharge through the CODEPAK, the strainermay be located upstream from pumps to protect bothpump and CODEPAK. (Piping between strainer, pumpand CODEPAK must be very carefully cleaned beforestartup.) If pumps are remotely installed from CODE-PAK, strainers should be located directly upstream ofthe CODEPAK.

Cooling Units – Condenser Water Circuit

For proper operation of the unit, condenser refrigerantpressure must be maintained above cooler pressure. Ifoperating conditions will fulfill this requirement, no at-

tempt should be made to control condenser watertemperature by means of automatic valves, cycling ofthe cooling tower fan or other means, since CODEPAKSare designed to function satisfactorily and efficientlywhen condenser water is allowed to seek its own tem-perature level at reduced loads and off-peak seasonsof the year. However, if entering condenser water tem-perature can go below the required minimum, (refer to160.49-O1) condenser water temperature must be main-tained equal to or slightly higher than the required mini-mum. Refer to Fig. 8 for typical water piping schematicfor cooling CODEPAK.

Stop Valves

Stop valves may be provided (by others) in the coolerand condenser water piping adjacent to the unit to fa-cilitate maintenance. Thermometer wells and pressuretaps should be provided (by others) in the piping as closeto the unit as possible to facilitate operating checks.

Flow Switches (Field Installed)

A flow switch or pressure differential control in the chilledwater line(s) adjacent to the unit is an accessory fur-nished for connection to the control center. If a flowswitch is used, it must be directly in series with theCODEPAK and sensing only water flow through theCODEPAK. The differential switch must sense pressuredrop across the unit.

Drain and Vent Valves

Drain and vent valves (by others) should be installed inthe connections provided in the cooler and condenserliquid heads. These connections may be piped to drainif desired.

Checking Piping Circuits and Venting Air

After the water piping is completed, but before any wa-ter box insulation is applied. Tighten and torque (to main-tain between 30 and 60 ft. lbs. – 415 and 830 kgm) thenuts on the liquid head flanges. Gasket shrinkage andhandling during transit cause nuts to loosen. If waterpressure is applied before this is done, the gaskets may

FORM 160.49-N1

FIG. 9 – REFRIGERANT VENT PIPING

LD01052

be damaged and have to be replaced. Fill the chilledand condenser water circuits (and hot water circuit onheat recovery unit), operate the pumps manually andcarefully check the cooler and condenser water headsand piping for leaks. Repair leaks as necessary.

Before initial operation of the unit both water circuits (orall three water circuits heat recovery units) should bethoroughly vented of all air at the high points.

REFRIGERANT RELIEF PIPING

Each unit is equipped with dual pressure relief valveslocated on the cooler for the purpose of quickly reliev-ing excess pressure of the refrigerant charge to the at-mosphere as a safety precaution in case of an emer-gency, such as fire.

Refrigerant relief vent piping (by others), from the reliefvalves to the outside of the building, is required by codein most areas and should be installed on all CODEPAKS.The vent line should be sized in accordance with theANSI/ ASHRE-15, or local code, but should never besmaller than “Relief Valve Size” shown in Figs. 3 or4. The vent line must include a dirt trap in the verticalleg to intercept and permit clean out and to trap anyvent stack condensation. The piping MUST be arrangedto avoid strain on the relief valves, using a flexible con-nection, if necessary.

UNIT PIPING

Compressor lubricant piping and system external pip-ing are factory installed on all units shipped assembled.On units shipped dismantled, the following piping shouldbe completed under the supervision of the YORK rep-resentative; (1) The lubricant piping to oil sump and oilcooler and system oil return connections using mate-rial furnished. See Form 160.49-N3.

CONTROL WIRING

On units shipped disassembled, after installation of thecontrol center, control wiring must be completed be-

tween unit components and control center or solid statestarter when used, using wiring harness furnished. Re-fer to Form 160.49-N3 and Wiring Diagrams listed inTable 4.

Field wiring connections for commonly-encounteredcontrol modifications (by others) if required, are shownon Forms 160.49-PW3.

NOTE: No deviations in unit wiring from that shownon drawings furnished shall be made withoutprior approval of the YORK representative.
