FIGURE 1 - MODEL YK CHILLER

GENERALThis manual describes the installation of a YORK YK Mod "H" Centrifugal Chiller. This unit can be shipped as a single factory assembled, piped, wired package, requiring a minimum of field labor to make chilled water connections, condenser water connections, re-frigerant atmospheric relief connections, and electri-cal power connections. Refrigerant and oil charges are shipped separately unless optional condenser isolation valves are ordered.

Chillers can also be shipped dismantled when required by rigging conditions, but generally it is more econom-ical to enlarge access openings to accommodate the factory assembled unit. Chillers shipped dismantled MUST be field assembled under the supervision of a Johnson Controls representative, but otherwise instal-lation is as described in this instruction.

FIELD ASSEMBLED UNITS ONLYUse Unit - Installation Instructions (Form 160.76-N3) in conjunction with this installation instruction. This in-struction is furnished with all units that are assembled in the field.

1INSPECTION – DAMAGE – SHORTAGEThe unit shipment should be checked on arrival to see that all major pieces, boxes and crates are received. Check each unit on the trailer or rail car when received, before unloading, for any visible signs of damage. Re-port any damage or signs of possible damage to the transportation company immediately for their inspec-tion. Johnson Controls is not be responsible for any damage in shipment, at job site, or loss of parts. (Refer to Shipping Damage Claims, Form 50.15-NM.)

When received at the job site, open all containers and check contents against the packing list. Any material shortage should be reported to Johnson Controls im-mediately. (Refer to Shipping Damage Claims, Form 50.15-NM.)

CHILLER DATA PLATEA unit data plate is mounted on the control center as-sembly of each unit, giving unit model number; design working pressure; water passes; refrigerant charge; se-rial numbers; and motor power characteristics and con-nection diagrams.

Additional information may be found on the motor data plate. Include this information when contacting the fac-tory on any problem relating to the motor.

LONG-TERM STORAGETo protect the waterbox of pressure vessels from rust-ing, the tube side (water side) is purged and charged with nitrogen to a positive pressure of 5 psig to 7 psig.

Do not break the seal or remove closures until ready for set up. Use the following procedure to relieve pres-sure (see Figure 3 on page 10).

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

1To relieve pressure, complete the following steps:

1. Check that the working space is open and has good ventilation. If not, it does not have good ven-tilation, and you should 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 should decline gradually.

4. When the pointer of 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 water-box, 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 Form 2/3/7/9All openings on the compressor, shells including evap-orator and condenser, and oil reservoir are closed and charged with nitrogen (2 psig to 3 psig). To remove the closures, sealing caps, or sealing plug under pressure is extremely dangerous, and may cause severe injury or death to the operator or people on-site.

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

When relieving the pressure from com-pressor, shells, or system, conduct the nitrogen to outside to prevent the potential risk of asphyxiation..

Shipment Form 1/10The unit is shipped with refrigerant charge; it is not necessary to relieve the pressure. DO NOT try to open any valves to relieve pressure or open closures, cap, or plugs on the compressor, shells, and elsewhere on the system.

Reclaim the refrigerant in the system before carrying out any service activities on the refrigeration system. Fully relieve system pressure and then repair.

The unit is charged with tons of refriger-ant; if an uncontrollable leak is found, inform all of the relevant people to evacu-ate from the building to prevent risk of asphyxiation.

Never touch the refrigerant that is leak-ing, especially the liquid refrigerant; this will cause severe freezing to your hands or body.

JOHNSON CONTROLS12


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

LD19197

RIGGINGThe complete standard chiller is shipped without skids. (When optional skids are used it may be necessary to remove the skids so riggers skates can be used under the unit end sheets to reduce overall height.)

Each unit has four (4) lifting holes (two in each end) in the end sheets, which should be used to lift the unit.

Care should be taken at all times during rigging and handling of the chiller to avoid damage to the unit and its external connections. Lift only using holes shown in Figure 4 on page 13.

Do not lift the unit with slings around motor/compressor assembly or by means of eyebolts in the tapped holes of the compressor motor assembly. Do not turn a unit on its side for rigging. Do not rig vertically.

The rigging and operating weights and overall dimen-sions are given from page 26 as a guide in determin-ing the clearances required for rigging. Add 6 in. (15 cm) to overall height for optional skidded unit.

LOCATIONYORK Chillers are furnished with vibration isola-tor mounts for basement or ground level installations. Units may be located on upper floor levels providing the floor is capable of supporting the total unit operat-ing weight and optional spring isolators are used.

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

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 fan cover diame-ter. Check the cooling fan condition. Clean the air inlet and outlet openings to ensure that there is free airflow over the motor.

For units that are shipped disassembled, before rigging is completed, make sure that the eyebolts are properly selected and tightened. Use all of the designed eyebolts to lift the motor. The coupling alignment must be ful-filled correctly.

FOUNDATIONA level floor, mounting pad or foundation must be pro-vided by others, capable of supporting the operating weight of the unit.

SECTION 2 - INSTALLATION

RIGGING UNIT TO FINAL LOCATIONRig the unit to its final location on the floor or mount-ing pad, lift the unit (or shell assembly) by means of an overhead lift, and lower the unit to its mounting posi-tion. If optional shipping skids are used, remove them before lowering the chiller to its mounting position.

At this point units shipped dismantled should be assembled under the supervi-sion of a Johnson Controls representative.

If the evaporator is to be field insulated, apply the insu-lation to the evaporator before the unit is placed in po-sition while the unit is in the lift position. Be sure unit is properly supported. (See Figure 4 on page 13)

LOCATING AND INSTALLING ISOLATOR PADSInstall the isolator pad mounts in the location shown in Figure 5 on page 14 (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 unit should be level within 1/4 in. (6 mm) from one end to the other end and from front to the rear. If the chiller is not level within the amount specified, lift it and place shims between the isolation pad and the chiller tube sheets. (Shims furnished by the installer.) Lower unit again and re-check to see 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 pad is under-deflected, shims must be placed between the unit tube sheet and the top of the pad to equally deflect all pads.

LEVELING THE UNITThe longitudinal alignment of the unit should be checked by placing a level on the top center of the evaporator shell under the compressor/motor assem-bly. Transverse alignment should be checked by plac-ing a level on top of the shell end sheets.

INSTALLING OPTIONAL SPRING ISOLATORSWhen ordered, spring type isolator assemblies are fur-nished with the unit. The 4 assemblies are identical and can be placed at any of the 4 corners of the unit.

While the unit is still suspended by the rigging, the iso-lators should be bolted to the unit by inserting the cap screws through the holes in the mounting bracket into the tapped hole in the top of the isolator leveling bolts. Then the unit can be lowered onto the floor.

The adjusting bolts should now be rotated one (1) turn at a time, in sequence, until the unit end sheets are clear of the floor by the dimension shown in Figure 7 on page 16 and the unit is level. Check that the unit is level, both longitudinally and transversely (see Leveling the Unit). If the leveling bolts are not long enough to level unit due to an uneven or sloping floor or foundation, steel shims (grouted, if necessary) must be added beneath the isolator assemblies as necessary.

After the unit is leveled, wedge and shim under each corner to solidly support the unit in this position while piping connections are being made, pipe hangers ad-justed and connections checked for alignment. Then the unit is filled with water and checked for leaks. The leveling bolts should now be finally adjusted 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 CONNECTIONSAfter the unit is leveled (and wedged in place for op-tional spring isolators) the piping connections may be made; chilled water, condenser water and refrigerant relief. The piping should be arranged with offsets for flexibility, and adequately supported and braced inde-pendently of the unit to avoid strain on the unit and vibration transmission. The hangers must allow for alignment of pipe. Isolators (by others) in the piping and hangers are highly desirable, and may be required by specifications, in order to effectively utilize the vi-bration isolation characteristics of the vibration isola-tion mounts of the unit.

Check for piping alignment – Upon completion of piping, a connection in each line as close to the unit as possible should be opened, by removing the flange bolts or coupling and checked for piping alignment. If

JOHNSON CONTROLS20

FORM 160.76-N1 ISSUE DATE: 06/21/2019SECTION 2 - INSTALLATION

any of the bolts are bound in their holes, or if the con-nection springs are out of alignment, the misalignment must be corrected by properly supporting the piping or by applying heat to anneal the pipe.

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

EVAPORATOR AND CONDENSER WATER PIPINGThe evaporator and condenser liquid heads of the chill-er have nozzles which are grooved, suitable for weld-ing 150 psig DWP flanges or the use of flexible cou-plings. Factory mounted flanges are optional.

The nozzles and water pass arrangements are furnished in accordance with the job requirements (refer to Prod-uct Drawings) furnished with the job. Standard units are designed for 150 psig DWP on the water side. If job re-quirements are for greater than 150 psig DWP, check the unit data plate before applying pressure to evaporator or condenser to determine if the chiller has provisions for the required DWP.

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

The coolant temperature inside any JCI-supplied liquid-cooled motor starter must be maintained above the dewpoint temperature in the equipment room to prevent condensing water vapor inside the starter cabinet. Therefore, an addi-tional temperature-controlled throttle valve is needed in the

flow path for the starter heat exchanger to regulate cooling above the equipment room dewpoint for applications using cooling sources other than evaporative air-exchange meth-ods, such as wells, bodies of water, and chilled water. The temperature control valve should be the type to open on in-creasing drive coolant temperature, fail-closed, and set for a temperature above dewpoint. It can be requested as factory- supplied on a chiller order by special quotation.

Chilled WaterForeign objects which could lodge in, or block flow through, the evaporator and condenser tubes must be kept out of the water circuit. All water piping must be cleaned or flushed before being connected to the chiller pumps, or other equipment.

Permanent strainers (supplied by others) are required in both the evaporator and condenser water circuits to protect the chiller as well as the pumps, tower spray nozzles, chilled water coils and controls, etc. The strainer must be installed in the entering chilled water line, directly upstream of the chiller.

Water piping circuits should be arranged so that the pumps discharge through the chiller, and should be controlled as necessary to maintain essentially constant chilled and condenser water flows through the unit at all load conditions.

If pumps discharge through the chiller, the strainer may be located upstream from pumps to protect both pump and chiller. (Piping between strainer, pump and chill-er must be very carefully cleaned before start-up.) If pumps are remotely installed from the chiller, strainers should be located directly upstream of the chiller.

Condenser Water CircuitFor proper operation of the unit, condenser refrigerant pressure must be maintained above evaporator pres-sure. If operating conditions fulfill this requirement, no attempt should be made to control condenser water temperature by means of automatic valves, cycling of the cooling tower fan or other means, since chillers are designed to function satisfactorily and efficiently when 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 the required minimum, refer to Operation - Unit (Form 160.76-O1); condenser water temperature must be maintained equal to or slightly higher than the required minimum. See Figure 8 on page 20 for typ-ical water piping schematic.

Stop ValvesStop valves may be provided (by others) in the evapora-tor and condenser water piping adjacent to the unit to facilitate maintenance. Thermometer wells and pressure taps should be provided (by others) 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 nozzles and are factory wired to the OptiView control panel. These solid-state flow sensors have a small internal heating element and use the cooling effect of the flowing fluid to sense when an adequate flow rate has been established.

Paddle flow switches are also offered according to the design working pressure (DWP) of the waterbox. If the DWP is 150 psig, select P/N 024-26116-000 for a flow switch with low energy gold flash 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 oper-ating range of the differential pressure switch is up to 40 psi, with a deadband of 0.5 psi to 0.8 psi. It has 1/4 NPTE pressure connections and 1/2 in. NPT conduit entry. The P/N for the differential pressure switch is 025-30919-000.

Waterbox Drain and Vent ValvesDrain and vent valves (by others) should be installed in the connections provided in the evaporator and con-denser liquid heads. These connections may be piped to drain if desired.

Checking Piping Circuits and Venting AirAfter the water piping is completed, but before any waterbox insulation is applied, tighten and torque the nuts on the liquid head flanges to maintain between 30 and 60 ft. lbs. (41 and 81 N·m). Gasket shrinkage and handling during transit cause nuts to loosen. If wa-ter pressure is applied before tightening is done, the gaskets may be damaged and have to be replaced. Fill the chilled and condenser water circuits, operate the pumps manually and carefully check the evaporator and condenser water heads and piping for leaks. Repair leaks as necessary.

Before initial operation of the unit both water circuits should be thoroughly vented of all air at the high points.

UNIT PIPINGCompressor lubricant piping and system external pip-ing are factory installed on all units shipped assembled. On units shipped dismantled, the following piping should be completed under the supervision of the John-son Controls representative: the lubricant piping to oil sump and oil cooler and system oil return connections using material furnished.

REFRIGERANT RELIEF PIPINGEach unit is equipped with pressure relief valves lo-cated on the condenser and on the evaporator for the purpose of quickly relieving excess pressure of the re-frigerant charge to the atmosphere as a safety precau-tion in case of an emergency, such as fire.

Refrigerant relief vent piping (by others), from the re-lief valves to the outside of the building, is required

by code in most areas and should be installed on all chillers. The vent line should be sized in accordance with the ANSI/ASHRAE-15, or local code. The vent line must include a dirt trap in the vertical leg to in-tercept and permit clean out and to trap any vent stack condensation. The piping MUST be arranged to avoid strain on the relief valves, using a flexible connection, if necessary.

JOHNSON CONTROLS24


Chiller with Solid State Starter or Variable Speed DriveA chiller equipped with a factory mounted Solid State Starter or Variable Speed Drive does not require wiring to the compressor motor. The motor power wiring is factory connected to the Solid State Starter or Variable Speed Drive. Refer to the Field Wiring Diagram. All wiring to the control panel and the oil pump starter is completed by the factory. A control transformer is fur-nished with the Solid State Starter or Variable Speed Drive.

Copper Conductors – Only connect cop-per conductors to compressor motors and starters. Aluminum conductors have proven to be unsatisfactory when con-nected to copper lugs. Aluminum oxide and the difference in thermal conductiv-ity between copper and aluminum mean the required tight connection cannot be guaranteed over a long period of time.

INSULATIONDO NOT field insulate until the unit has been leak tested under the supervision of the Johnson Controls representative.

Insulation of the type specified for the job, or mini-mum thickness to prevent sweating of 30°F (-1°C) sur-faces should be furnished (by others) and applied to the evaporator shell, end sheets, liquid feed line to flow chamber, compressor suction connection, and evapo-rator liquid heads and connections. The liquid head flange insulation must be removable, to allow head re-moval for the tube maintenance. Details of areas to be insulated are given on the Product Drawing.

Units are furnished factory anti-sweat insulated on or-der at additional cost. This includes all low tempera-ture surfaces except the two (2) cooler liquid heads.

INSTALLATION CHECK – REQUEST FOR START-UP SERVICEThe services of a Johnson Controls representative will be furnished to check the installation and supervise the initial start-up and operation on all chillers installed within the Continental United States.

After the unit is installed, piped and wired as described in this Instruction, but before any attempt is made to start the unit, the Johnson Controls District Office should be advised so that the start-up service, included in the contract price, can be scheduled. Use the In-stallation Checklist and Request for startup, (Form 160.76-CL1).
