Chiller data plateA unit data plate is mounted on the control center assembly of each unit, giving the followinginformation:

• Unit model number• Design working pressure• Water passes• Refrigerant charge• Serial numbers• Motor power characteristics and connection diagrams

Additional information may be found on the motor data plate. Include this information whencontacting the factory on any problem relating to the motor.

Long-term storageAbout this task: To protect the waterbox of pressure vessels from rusting, the tube side (water side) is purged andcharged with nitrogen to a positive pressure of 5 psig to 7 psig.

Do not break the seal or remove closures until ready for setup. Use the following procedure torelieve pressure. See Figure 3.

WARNING

Failure to follow the following procedures will cause severe personal injury or death to operatorsthemselves or people on-site. It is the obligation and responsibility of operators to identify andrecognize the inherent hazards of material under pressure and to protect themselves.

1. Check that the working space is open and has good ventilation. If ventilation is not good,connect a hose or pipe to the valve (Item 5) and route it to outside.

2. Slowly open the valve (Item 5) until fully opened.3. Monitor the pressure gauge (Item 2). The pressure declines gradually.4. When the pointer of the pressure gauge stops moving and no nitrogen is released from the

valve (Item 5), no positive pressure exists in the waterbox.5. When there is no positive pressure in the waterbox, it is safe to remove the flange cover (Item

6) or sealing cap (Item 9).6. Close the valve (Item 5) and remove the warning tag (Item 1).

Shipment Forms 2,3,7,9All openings on the compressor, shells including evaporator and condenser, and oil reservoir areclosed and charged with nitrogen (2 psig to 3 psig). To remove the closures, sealing caps, or sealingplug under pressure is extremely dangerous, and may cause severe injury or death to the operatoror people on-site.

WARNING

Before trying to remove the closures, caps, or plugs on compressor and shells, relieve the pressure incompressor, shells, or system that are charged with nitrogen by opening the valves on them slowlyuntil fully open.

WARNING

When relieving the pressure from compressor, shells, or system, conduct the nitrogen to outside toprevent the potential risk of asphyxiation..

Shipment Forms 1,10The unit is shipped with refrigerant charge; it is not necessary to relieve the pressure. Do not try toopen any valves to relieve pressure or open closures, cap, or plugs on the compressor, shells, andelsewhere on the system.Reclaim the refrigerant in the system before carrying out any service activities on the refrigerationsystem. Fully relieve system pressure and then repair.

DANGER

The unit is charged with tons of refrigerant; if an uncontrollable leak is found, inform all of the relevantpeople to evacuate from the building to prevent risk of asphyxiation.

Never touch the refrigerant that is leaking, especially the liquid refrigerant; this will cause severefreezing to your hands or body.


Rigging

Figure 4: Rigging warning

DANGER

Rigging and lifting should only be done by a professional rigger in accordance with a written riggingand lifting plan. The most appropriate rigging and lifting method depends on job specific factors, suchas the rigging equipment available and site needs. Therefore, a professional rigger must determine therigging and lifting method to be used, and it is beyond the scope of this manual to specify rigging andlifting details.

The complete standard chiller is shipped without skids. When optional skids are used it may benecessary to remove the skids so riggers skates can be used under the unit end sheets to reduceoverall height.Each unit has four lifting holes (two in each end) in the end sheets, which should be used to lift theunit.Care must be taken at all times during rigging and handling of the chiller to avoid damage to theunit and its external connections. Lift only using holes shown in Figure 5.

CAUTION

Do not lift the unit with slings around motor/compressor 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 rigvertically.

The rigging and operating weights and overall dimensions are given from page as a guide indetermining the clearances required for rigging. Add 6 in. (15 cm) to overall height for optionalskidded unit.


LocationYORK® chillers are furnished with vibration isolator mounts for basement or ground levelinstallations. Units may be located on upper floor levels providing the floor is capable of supportingthe total unit operating weight and optional spring isolators are used.Locate the chiller control panel in a physically secured area with access only to authorizedpersonnel. To further tighten security, ensure that the control panel is mechanically locked. Removethe keys to the control panel and store them in a secure location.

CAUTION

Sufficient clearance to facilitate normal service and maintenance work must be provided all aroundand above the unit and particularly space provided at either end to permit cleaning or replacement ofevaporator and condenser tubes. See Clearance. A doorway or other sufficiently large opening properlylocated may be used. The chiller should be located in an indoor location where temperatures rangefrom 40°F to 110°F (4.4°C to 43.3°C).

Figure 5: Rigging

MotorsThe YK open motor is air cooled. Check state, local, and other codes for ventilation requirements.The minimum clearance to the nearest wall must be at least one-quarter of the length of the fancover diameter. Check the cooling fan condition. Clean the air inlet and outlet openings to ensurethat there is free airflow over the motor.For units that are shipped disassembled, before rigging is completed, make sure that the eyeboltsare properly selected and tightened. Use all of the designed eyebolts to lift the motor. The couplingalignment must be fulfilled correctly.


FoundationA level floor, mounting pad or foundation must be provided by others, capable of supporting theoperating weight of the unit.

Note: All dimensions are in inches (mm)


Installation

Rigging unit to final locationRig the unit to its final location on the floor or mounting pad, lift the unit (or shell assembly) bymeans of an overhead lift, and lower the unit to its mounting position. If optional shipping skids areused, remove them before lowering the chiller to its mounting position.

Note: At this point, units shipped dismantled must be assembled under the supervision of aJohnson Controls representative.

If the evaporator is to be field insulated, apply the insulation to the evaporator before the unit isplaced in position while the unit is in the lift position. Be sure unit is properly supported. See Figure5.

Locating and installing isolator padsInstall the isolator pad mounts in the location shown in Clearance (rubber side down).After the isolator pads have been placed into position on the floor, lower the chiller onto the pads.When the unit is in place, remove the rigging equipment and check that the unit is level. The unitshould be level within 1/4 in. (6 mm) from one end to the other end and from front to the rear. Ifthe chiller is not level within the amount specified, lift it and place shims between the isolation padand the chiller tube sheets. Shims are furnished by the installer. Lower unit again and recheck tosee that it is level.

Checking the isolation pad deflectionCheck all isolation pads for the proper deflection while also checking to see if the unit is level.Each pad must be deflected approximately 0.10 in. (2.5 mm) to 0.20 in. (5 mm). If an isolation padis under-deflected, shims must be placed between the unit tube sheet and the top of the pad toequally deflect all pads.

Leveling the unitThe longitudinal alignment of the unit should be checked by placing a level on the top center ofthe evaporator shell under the compressor and motor assembly. Transverse alignment should bechecked by placing a level on top of the shell end sheets.

Installing optional spring isolatorsWhen ordered, spring type isolator assemblies are furnished with the unit. The four assemblies areidentical and can be placed at any of the 4 corners of the unit.While the unit is still suspended by the rigging, bolt the isolators to the unit by inserting the capscrews through the holes in the mounting bracket into the tapped hole in the top of the isolatorleveling bolts. The unit can then be lowered onto the floor.Rotate the adjusting bolts now one turn at a time, in sequence, until the unit end sheets are clear ofthe floor by the dimension shown in Figure 8 and the unit is level. Check that the unit is level, bothlongitudinally and transversely (see Leveling the unit). If the leveling bolts are not long enough tolevel unit due to an uneven or sloping floor or foundation, steel shims (grouted, if necessary) mustbe added beneath the isolator assemblies as necessary.After the unit is leveled, wedge and shim under each corner to solidly support the unit in thisposition while piping connections are being made, pipe hangers adjusted, and connections checkedfor alignment. Fill the unit with water and check for leaks. Perform a final adjustment of the leveling


bolts until the wedges and shims can be removed. The unit should now be in correct level position,clear of the floor or foundation and without any effect from the weight of the piping.

Piping connectionsMake the piping connections after the unit is leveled (and wedged in place for optional springisolators): chilled water, condenser water and refrigerant relief. The piping must be arrangedwith offsets for flexibility, and adequately supported and braced independently of the unit toavoid strain on the unit and vibration transmission. The hangers must allow for alignment ofpipe. Isolators (by others) in the piping and hangers may be necessary, and may be required byspecifications, in order to effectively use the vibration isolation characteristics of the vibrationisolation mounts of the unit.Check for piping alignment: Upon completion of piping, open a connection in each line as closeto the unit as possible. Remove the flange bolts or coupling and check for piping alignment. Ifany of the bolts are bound in their holes, or if the connection springs are out of alignment, themisalignment must be corrected by supporting the piping correctly or by applying heat to annealthe pipe.

Note: If the piping is annealed to relieve stress, the inside of the pipe must be cleaned of scalebefore it is finally bolted in place.

Evaporator and condenser water pipingThe evaporator and condenser liquid heads of the chiller have nozzles which are grooved, suitablefor welding 150 psig DWP flanges or the use of flexible couplings. Factory mounted flanges areoptional.The nozzles and water pass arrangements are furnished in accordance with the job requirements(refer to product drawings) for the job. Standard units are designed for 150 psig DWP on thewater side. If job requirements are for greater than 150 psig DWP, check the unit data plate beforeapplying pressure to evaporator or condenser to determine if the chiller has provisions for therequired DWP.Inlet and outlet connections are identified by labels placed adjacent to each nozzle.The coolant temperature inside any liquid-cooled motor starter supplied by Johnson Controls mustbe maintained above the dewpoint temperature in the equipment room to prevent condensingwater vapor inside the starter cabinet. To ensure this, an additional temperature-controlled throttlevalve is needed in the flow path for the starter heat exchanger to regulate cooling above theequipment room dewpoint, for applications using cooling sources other than evaporative air-exchange methods, such as wells, bodies of water, and chilled water. The temperature controlvalve must be the type to open on increasing drive coolant temperature, fail-closed, and set for atemperature above dewpoint. It can be requested as factory-supplied on a chiller order by specialquotation.


Figure 9: Schematic of a typical piping arrangement

Chilled waterForeign objects which could lodge in, or block flow through, the evaporator and condenser tubesmust be kept out of the water circuit. Clean or flush all water piping before connecting to the chillerpumps, or other equipment.Permanent strainers (supplied by others) are required in both the evaporator and condenserwater circuits to protect the chiller as well as the pumps, tower spray nozzles, chilled water coils andcontrols. The strainer must be installed in the entering chilled water line, directly upstream of thechiller.Arrange water piping circuits so that the pumps discharge through the chiller. Control the waterpiping circuits to maintain essentially constant chilled and condenser water flows through the unitat all load conditions.If pumps discharge through the chiller, locate the strainer upstream from the pumps to protectboth pump and chiller. Clean the piping between the strainer, pump and chiller very carefullybefore start-up. If pumps are remotely installed from the chiller, locate the strainers directlyupstream of the chiller.

Condenser water circuitFor proper operation of the unit, condenser refrigerant pressure must be maintained aboveevaporator pressure. If operating conditions fulfill this requirement, no attempt should be madeto control condenser water temperature by means of automatic valves, cycling of the coolingtower fan or other means, since chillers are designed to function satisfactorily and efficientlywhen condenser water is allowed to seek its own temperature level at reduced loads and off-peak seasons of the year. However, if entering condenser water temperature can go below therequired minimum, refer to Operation - Unit (Form 160.76-O1); condenser water temperature mustbe maintained equal to or slightly higher than the required minimum. See Figure 9 for typical waterpiping schematic.

Stop valvesStop valves may be provided (by others) in the evaporator and condenser water piping adjacent tothe unit to facilitate maintenance. Thermometer wells and pressure taps should be provided (byothers) in the piping as close to the unit as possible to facilitate operating check.


Flow switchesThermal type water flow switches are factory mounted in the chilled and condensed water nozzlesand are factory wired to the OptiView control panel. These solid-state flow sensors have a smallinternal heating element and use the cooling effect of the flowing fluid to sense when an adequateflow rate has been established.Paddle flow switches are also offered according to the design working pressure (DWP) of thewaterbox. If the DWP is 150 psig, select P/N 024-26116-000 for a flow switch with low energy goldflash contacts. For 300 psig, choose the flow switch with P/N 024-12144-000.Additionally, a differential pressure switch is available with 300 psi of maximum working pressure.The operating range of the differential pressure switch is up to 40 psi, with a deadband of 0.5 psito 0.8 psi. It has 1/4 NPTE pressure connections and 1/2 in. NPT conduit entry. The P/N for thedifferential pressure switch is 025-30919-000.

Waterbox drain and vent valvesDrain and vent valves (by others) must be installed in the connections provided in the evaporatorand condenser liquid heads. These connections can be piped to drain.

Checking piping circuits and venting airAfter the water piping is completed, but before any waterbox insulation is applied, tighten andtorque the nuts on the liquid head flanges to maintain between 30 and 60 ft. lbs. (41 and 81N·m). Gasket shrinkage and handling during transit can cause nuts to loosen. Applying waterpressure before tightening can damage the gaskets, requiring their replacement. Fill the chilledand condenser water circuits, operate the pumps manually and carefully check the evaporator andcondenser water heads and piping for leaks. Repair leaks as necessary.Before initial operation of the unit, vent both water circuits thoroughly of all air at the high points.

Unit pipingCompressor lubricant piping and system external piping are factory installed on all units shippedassembled. On units shipped dismantled, the following piping must be completed under thesupervision of the Johnson Controls representative: the lubricant piping to oil sump and oil coolerand system oil return connections using material furnished. Refer to Installation - Unit (Form 160.76-N3).

Refrigerant relief pipingEach unit is equipped with pressure relief valves located on the condenser and on the evaporatorfor the purpose of quickly relieving excess pressure of the refrigerant charge to the atmosphere asa safety precaution in case of an emergency, such as fire.Refrigerant relief vent piping (by others), from the relief valves to the outside of the building, isrequired by code in most areas and must be installed on all chillers. The vent line must be sizedin accordance with the ANSI/ASHRAE-15 or local code. The vent line must include a dirt trap inthe vertical leg to intercept and permit clean out and to trap any vent stack condensation. Thepiping must be installed, with hangers if needed, and must fitted and adjusted so that there is nopiping strain in any direction on the relief valves. See Figure 10. Although a flexible piping section ispreferable, it cannot be used to account for any misalignment, only to isolate for vibration.


Figure 10: Typical refrigerant vent piping

Note:

When installing relief piping, there must not be any piping strain. Relief piping must beproperly aligned and supported to eliminate any possible strain.

When installing relief piping, an ANSI flange or a piping union must be used to make aserviceable piping connection.


Control panel positioningAbout this task: On large YK chillers equipped with H9 and K1-K7 compressors, the control panel height can beadjusted. On chillers that are equipped with P and Q compressors, the control panel height is notadjustable. The OptiView™ control center is placed in a position above the evaporator for shipping.

To move the control center into position for operation, proceed as follows:

1. Remove the hardware between the support arms and the evaporator, while supporting thecontrol center. .

2. Swing the control center into a vertical position.3. Slide the control center down the guide rails to the proper position. Tighten securely.4. Discard unused hardware.

Figure 11: Control panel positioning

Control wiringYou must complete the control wiring on units shipped disassembled. After installation of thecontrol center, use the wiring harnesses furnished to complete the control wiring between unitcomponents and the control center, solid state starter, or variable speed drive, when used. Refer toInstallation - Unit (Form 160.76-N3).Field wiring connections for commonly encountered control modifications (by others) if required,are shown on Wiring Diagram – Unit (Style H) Field Control Modifications (Form 160.76-PW4).

Note: No deviations in unit wiring from that shown on drawings furnished can be madewithout prior approval of the Johnson Controls representative.


Power wiringChiller with electromechanical starterA 115 V – single phase – 60 Hz or 50 Hz power supply of 20 A must be furnished to the controlcenter, from the control transformer (2 KVA required) included with the compressor motor starter.Do not make final power connections to control center until approved by YORK representative.

Oil pump – three-phase starterSeparate wiring or a fused disconnect switch must be supplied by the installer.

Note: Remote electromechanical starters for the chiller must be furnished in accordance withYORK Starter Specifications Product Drawing, Form 160.76-PW5 to provide the features necessaryfor the starter to function correctly with the YORK control system.

Each chiller unit is furnished for a specific electrical power supply as stamped on the unit data plate,which also details the motor connection diagrams.

Note: To insure correct motor rotation, the starter power input and starter to motorconnections must be checked with a phase sequence indicator in the presence of the JohnsonControls representative.

CAUTION

DO NOT cut wires to final length or make final connections to motor terminals or starter power inputterminals until approved by the Johnson Controls representative.

YK motors (electromechanical starter)Motor leads are furnished with a crimp type connection having a clearance hole for a 3/8 in. bolt,motor terminal lugs are not furnished. Refer to Wiring Labels in motor terminal box for hook-up tosuit motor voltage and amperage for power wiring connections.

Chiller with solid state starter or variable speed driveA chiller equipped with a factory mounted solid state starter or variable speed drive does notrequire wiring to the compressor motor. The motor power wiring is factory connected to the solidstate starter or variable speed drive. Refer to the Field Wiring Diagram. All wiring to the controlpanel and the oil pump starter is completed by the factory. A control transformer is furnished withthe solid state starter or variable speed drive.

CAUTION

Copper Conductors – Only connect copper conductors to compressor motors and starters. Aluminumconductors have proven to be unsatisfactory when connected to copper lugs. Aluminum oxide and thedifference in thermal conductivity between copper and aluminum mean the required tight connectioncannot be guaranteed over a long period of time.


Insulation

CAUTION

DO NOT field insulate until the unit has been leak tested under the supervision of the Johnson Controlsrepresentative.

Insulation of the type specified for the job, or minimum thickness to prevent sweating of 30°F(-1°C) surfaces must be furnished (by others) and applied to the evaporator shell, end sheets,liquid feed line to flow chamber, compressor suction connection, and evaporator liquid heads andconnections. The liquid head flange insulation must be removable, to allow head removal for thetube maintenance. Details of areas to be insulated are given on the Product Drawing.Units are furnished factory anti-sweat insulated on order at additional cost. This includes all lowtemperature surfaces except the two (2) cooler liquid heads.

Installation check – request for start-up serviceThe services of a Johnson Controls representative is furnished to check the installation andsupervise the initial start-up and operation on all chillers installed within the continental UnitedStates.After the unit is installed, piped, and wired as described in this Instruction, but before any attemptis made to start the unit, the Johnson Controls District Office should be advised so that the start-upservice, included in the contract price, can be scheduled. Use the Installation Checklist and Requestfor startup, (Form 160.76-CL1).

Note:1. All dimensions are ft-in. (mm).2. All dimensions are approximate. Certified dimensions are available on request.3. For all waterboxes (compact boxes shown above), determine overall unit length by

adding waterbox depth to tube sheet length.4. Water nozzles can be located on either end of unit. Add 1/2 in. (12 mm) to nozzle length

for flanges connections.5. To determine overall height, add dimension M in Table 4 for the appropriate isolator

type.6. Use of motors with motor hoods may increase overall unit dimensions.

Note:1. All dimensions are ft-in. (mm).2. Standard water nozzles are furnished as welding stub-outs with ANSI/AWWA C-606

grooves, allowing the option of welding, flanges, or use of ANSI/AWWA C-606 couplings.Factory-installed, class 150 (ANSI B16.5, round slip-on, forged carbon steel with 1.6mm raised face), water flanges nozzles are optional (add 13 mm to nozzle length).Companion flanges, nuts, bolts, and gaskets are not furnished.

3. One, two and three pass nozzle arrangements are available only in pairs shown and forall shell codes. Any pair of evaporator nozzles may be used in combination with any pairof condenser nozzles.

4. Evaporator and condenser water must enter the waterbox through the bottomconnection to achieve rated performance.

5. Connected piping should allow for removal of compact waterboxes for tube access andcleaning.

6. Add dimension M in Table 4 for the appropriate isolator type.7. Standard 150 psi (1034 kPa) design pressure waterboxes shown.

Note:1. All dimensions are ft-in. (mm).2. All dimensions are approximate. Certified dimensions are available on request.3. For all waterboxes (compact boxes shown above), determine overall unit length by

adding waterbox depth to tube sheet length.4. Water nozzles can be located on either end of unit. Add 1/2 in. (12 mm) to nozzle length

for flanges connections.5. Add dimension "M" in Table 4 for the appropriate isolator type.6. Use of motors with motor hoods may increase overall unit dimensions.
