16 INTRODUCTION GENERAL This instruction describes the installation of a MODEL YK CODEPAK Liquid Chilling Unit. This unit is shipped as a single factory assembled, piped, wired package requiring a minimum of field labor to make chilled water connections, condenser water connections, refrigerant atmospheric relief connections, and electrical power connections. (Refrigerant and oil charges shipped separately.) CODEPAKS can also be shipped dismantled when required by rigging conditions, but generally it is more economical to enlarge access openings to accomodate the factory assembled unit. CODEPAKS shipped dismantled MUST be field assembled under the supervision of a YORK representative, but otherwise installation will be as described in this instruction. FIELD ASSEMBLED UNITS ONLY Use Form N3 in conjunction with this installation instruction. This instruction will be furnished with all units that are to be field assembled. Extra copies may be ordered from the YORK Publication Distribution Center. CONSTRUCTION DRAWINGS Construction drawings are furnished for each job as noted in Table 4. These drawings must be carefully followed and used in conjunction with this installation instruction, to insure proper installation of the unit. In event of any differences between drawings and this instruction, the drawings will govern. The services of a YORK representative will be furnished to check the installation, supervise the initial start-up and operation of all CODEPAKS installed within Continental United States. CAUTION: The YORK Warranty will be voided if the following restrictions are not adhered to: 1. No valves or connections should be opened under any circumstances because such action will result in loss of the factory nitrogen charge. 2. Do not dismantle or open the CODEPAK for any reason except under the supervision of a YORK representative. 3. When units are shipped dismantled, notify the nearest YORK office in ample time for a YORK representative to supervise rigging the unit to its operating position and the assembly of components. 4. Do not make final power supply connections to the compressor motor or control center. 5. Do not charge the compressor with oil. 6. Do not charge the unit with refrigerant. 7. Do not attempt to start the system. 8. Do not run hot water (110 F (43.3 C) max.) or steam through the cooler or condenser at any time. SHIPMENT The CODEPAK may be ordered and shipped in any of the following forms: Form 2 Factory Assembled Unit, complete with motor (refrigerant and oil charges shipped separately). 1. The motor/compressor assembly mounted, with all necessary interconnecting piping assembled. MicroComputer Control Center is mounted on the unit. Complete unit factory leak tested, evacuated and charged with holding charge of nitrogen. An optional Solid State Starter can be factory mounted and wired. 2. Miscellaneous material Four (4) vibration isolation pads (or optional spring isolators and brackets). Form 3 Driveline Separate From Shells Shipped as three major assemblies. Unit first factory assembled, refrigerant piped, wired and leak tested; then dismantled for shipment. Compressor/motor assembly removed from shells and skidded. Cooler/condenser is not skidded. All wiring integral with compressor is left on it, and all conduit is left on shell. All openings on compressor, oil separator, and shell are closed and charged with dry nitrogen (2 to 3 psig)(13.8 to 21 kpa).

When more than one CODEPAK is involved, the major parts of each unit will be marked to prevent mixing of assemblies. (Piping and Wiring Drawings to be furnished by YORK.) INSPECTION DAMAGE SHORTAGE The unit shipment should be checked on arrival to see that all major pieces, boxes and crates are received. Each unit should be checked on the trailer or rail car when received, before unloading, for any visible signs of damage. Any damage or signs of possible damage must be reported to the transportation company immediately for their inspection. YORK WILL NOT BE RESPONSIBLE FOR ANY DAM- AGE IN SHIPMENT OR AT JOB SITE OR LOSS OF PARTS. (Refer to Shipping Damage Claims, Form NM). When received at the job site all containers should be opened and contents checked against the packing list. Any material shortage should be reported to YORK immediately. (Refer to Shipping Damage Claims, Form NM.) CODEPAK DATA PLATE A unit data plate is mounted on the control center assembly of each unit, giving unit model number; design working pressure; water passes; refrigerant charge; serial numbers; and motor power characteristics and connection diagrams. Additional information may be found on the motor date plate. This information should be included when contacting the factory on any problem relating to the motor. RIGGING The complete standard CODEPAK 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 on each end) in the end sheets which should be used to lift the unit. (See Fig. 5.) Care should be taken at all times during rigging and handling of the CODEPAK to avoid damage to the unit and its external connections. Lift only using holes shown in Fig. 5. 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 by one end. Use of Slings (See Fig. 5 for proper use of slings in rigging.) CAUTION : If necessary to rig the CODEPAK by one end to permit lifting or dropping through a vertical passageway, such as an elevator shaft, contact YORK factory shipping for special rigging instructions. The rigging and operating weights and overall dimensions are given on pages 6 thru 13 as a guide in determining the clearances required for rigging. (Add 6" (153 mm) to overall-height for optional skidded unit.) YORK INTERNATIONAL 17

21 FORM N1 INSTALLATION RIGGING UNIT TO FINAL LOCATION Rig the unit to its final location on the floor or mounting pad, lift the unit (or shell assembly) by means of an overhead lift and lower the unit to its mounting position. (If optional shipping skids are used remove them before lowering the CODEPAK to its mounting position.) NOTE: At this point units shipped dismantled should be assembled under the supervision of a YORK representative. If cooler is to be field insulated, the insulation should be applied to the cooler before the unit is placed in position while the unit is in the lift position. Be sure unit is properly supported. (See INSULATION, page 24.) LOCATING AND INSTALLING ISOLATOR PADS (REFER TO FIG. 6) The isolator pad mounts are to be located as shown in Fig. 6. After the isolator pads have been placed into position on the floor, lower the CODEPAK onto the pads. When the unit is in place remove the rigging equipment and check that the unit is level both longitudinally and transversely. 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, lift it and place shims between the isolation pad and the CODEPAK tube sheets. (Shims furnished by the installer.) Lower unit again and recheck to see that it is level. CHECKING THE ISOLATION PAD DEFLECTION All isolation pads should be checked for the proper deflection 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, shims should be placed between the unit tube sheet and the top of the pad to equally deflect all pads. LEVELING THE UNIT The longitudinal alignment of the unit should be checked by placing a level on the top center of the cooler shell under the compressor/motor assembly. Transverse alignment should be checked by placing a level on top of the shell 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 be furnished 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 isolators should be bolted to the unit by inserting the cap screw(s) through the hole(s) in the mounting bracket into the tapped hole in the top of the isolator leveling bolt(s). Then the unit can be lowered onto the floor. The leveling bolts should now be rotated one (1) turn at a time, in sequence, until the unit end sheets are about 1-3/4" (44.4 mm) off the floor or foundation, 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 adjusted 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. When the unit is properly supported, spring isolator installed height will be 6" to 6-1/4" ( mm). PIPING CONNECTIONS After the unit is leveled (and wedged in place for optional spring isolators) the piping connections may be made up; chilled water, condenser water and refrigerant relief. The piping should be arranged with offsets for flexibility, and adequately supported and braced independently of the unit to avoid strain on the unit and vibration transmission. 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 vibration isolation characteristics of the vibration isolation 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 any of the bolts are bound in their holes, or if the connection springs out of alignment, the misalignment must be corrected by properly supporting the piping or by applying heat to anneal the pipe. NOTE: 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. COOLER AND CONDENSER WATER PIPING The cooler and condenser liquid heads of CODEPAK units have nozzles which are grooved, suitable for welding 150 psig DWP flanges or the use of Victaulic couplings. YORK INTERNATIONAL 21

22 The nozzles and water pass arrangements are furnished in accordance with the job requirements (see Product Drawings as referenced in Table 4) furnished with the job. Standard units are designed for 150 psig (1034 kpa) DWP on the water side. If job requirements are for greater than 150 psig (1034 kpa) DWP, check the unit data plate before applying pressure to cooler or condenser to determine if the CODEPAK has provisions for the required DWP. Inlet and outlet connections are identified by labels placed adjacent to each nozzle. Cooling Units Chilled Water Foreign objects which could lodge in, or block flow through, the cooler and condenser tubes must be kept out of the water circuit. All water piping must be cleaned or flushed before being connected to the CODEPAK, pumps, or other equipment. Permanent strainers (by others) are required in both the cooler and condenser water circuits to protect the CODEPAK as well as the pumps, tower spray nozzles, chilled water coils and controls, etc. The strainer should be installed in the entering chilled water line, directly up-stream of the CODEPAK. Water piping circuits should be arranged so that the pumps discharge through the CODEPAK, 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 CODEPAK, the strainer may be located upstream from pumps to protect both pump and CODEPAK. (Piping between strainer, pump and CODEPAK must be very carefully cleaned before startup.) If pumps are remotely installed from CODE- PAK, strainers should be located directly upstream of the CODEPAK. Cooling Units Condenser Water Circuit For proper operation of the unit, condenser refrigerant pressure must be maintained above cooler pressure. If operating conditions will 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 CODEPAKS 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 O1) condenser water temperature must be maintained equal to or slightly higher than the required minimum. Refer to Fig. 8 for typical water piping schematic for cooling CODEPAK. Stop Valves Stop valves may be provided (by others) in the cooler 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 checks. Flow Switches (Field Installed) A flow switch or pressure differential control in the chilled water line(s) adjacent to the unit is an accessory furnished for connection to the control center. If a flow switch is used, it must be directly in series with the CODEPAK and sensing only water flow through the CODEPAK. The differential switch must sense pressure drop across the unit. Drain and Vent Valves Drain and vent valves (by others) should be installed in the connections provided in the cooler and condenser liquid heads. These connections may be piped to drain if desired. Checking Piping Circuits and Venting Air After the water piping is completed, but before any water box insulation is applied. Tighten and torque (to maintain between 30 and 60 ft. lbs. 415 and 830 kgm) the nuts on the liquid head flanges. Gasket shrinkage and handling during transit cause nuts to loosen. If water pressure is applied before this is done, the gaskets may LD01051 FIG. 8 SCHEMATIC OF A TYPICAL PIPING ARRANGEMENT FOR COOLING ONLY CODEPAKS 22 YORK INTERNATIONAL

23 FORM N1 LD01052 FIG. 9 REFRIGERANT VENT PIPING be damaged and have to be replaced. Fill the chilled and condenser water circuits (and hot water circuit on heat recovery unit), operate the pumps manually and carefully check the cooler and condenser water heads and piping for leaks. Repair leaks as necessary. Before initial operation of the unit both water circuits (or all three water circuits heat recovery units) should be thoroughly vented of all air at the high points. REFRIGERANT RELIEF PIPING Each unit is equipped with dual pressure relief valves located on the cooler for the purpose of quickly relieving excess pressure of the refrigerant charge to the atmosphere as a 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, is required by code in most areas and should be installed on all CODEPAKS. The vent line should be sized in accordance with the ANSI/ ASHRE-15, or local code, but should never be smaller than Relief Valve Size shown in Figs. 3 or 4. The vent line must include a dirt trap in the vertical leg to intercept 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. UNIT PIPING Compressor lubricant piping and system external piping are factory installed on all units shipped assembled. On units shipped dismantled, the following piping should be completed under the supervision of the YORK representative; (1) The lubricant piping to oil sump and oil cooler and system oil return connections using material furnished. See Form N3. CONTROL WIRING On units shipped disassembled, after installation of the control center, control wiring must be completed between unit components and control center or solid state starter when used, using wiring harness furnished. Refer to Form N3 and Wiring Diagrams listed in Table 4. Field wiring connections for commonly-encountered control modifications (by others) if required, are shown on Forms PW3. NOTE: No deviations in unit wiring from that shown on drawings furnished shall be made without prior approval of the YORK representative. POWER WIRING Codepak with Electro-Mechanical Starter A 115 volt single phase 60 or 50 Hertz power supply of 15 amperes must be furnished to the control center, 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. OlL PUMP 3 PHASE STARTER Separate wiring or a fused disconnect switch should be supplied by the installer. Refer to the Field Wiring Diagram shown in Table 4. NOTE: Remote Electro-Mechanical starters for the CODEPAK must be furnished in accordance with YORK Standard R-1051 (Product Drawing Form PA5.1) to provide the features necessary for the starter to function properly with the YORK control system. Each CODEPAK 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 proper motor rotation the starter power input and starter to motor connections must be checked with a phase sequence indicator in the presence of the YORK representative. YORK INTERNATIONAL 23

24 IMPORTANT DO NOT cut wires to final length or make final connections to motor terminals or starter power input terminals until approved by the YORK representative. YK Motors (Electro-Mechanical Starter) Fig. 8 shows the power wiring hook-up for Motor Connections. (Refer to Wiring Labels in Motor Terminal Box for hook-up to suit motor voltage amd amperage.) Motor leads are furnished with a crimp type connection having a clearance hole for a 3/8" (9 mm) bolt, motor terminal lugs are not furnished. CODEPAK with Solid State Starter A CODEPAK equipped with a Solid State Starter, does not require wiring to the compressor motor. The motor power wiring is factory connected to the Solid State Starter (or an optional factory installed disconnect switch). See Field Wiring Diagram listed in Table 4. All wiring to the control panel and the oil pump starter is completed by the factory. A control transformer is furnished with the Solid State Starter. INSULATION (SEE PRODUCT DRAWING FORM PA1). IMPORTANT DO NOT field insulate until the unit has been leak tested under the supervision of the YORK representative. Insulation of the type specified for the job, or minimum thickness to prevent sweating of 30 F surfaces (water chill application), should be furnished (by others) and applied to the cooler shell, end sheets, liquid feed line to flow chamber, compressor suction connection, and cooler liquid heads and connections. The liquid head flange insulation must be removable, to allow head removal for the tube 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 low temperature surfaces except the two (2) cooler liquid heads. INSTALLATION CHECK REQUEST FOR START-UP SERVICE The services of a YORK representative will be furnished to check the installation and supervise the initial start-up and operation on all CODEPAKS 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 YORK District Office should be advised so that the start-up service, included in the contract price, can be scheduled. Notification to the YORK office should be by means of Installation Check List and Request, Form CL1, in triplicate. 3 PHASE MOTOR RATED LOAD AMPS MOTOR CT RATIO VOLTAGE 50/60 HZ 200:1 350:1 700:1 1400: A A A A C B A A A NOTES: A.
