10 section 1 - INTRODUCTION FOR N1 LD19197 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 will depend on job specific factors, such as the rigging equipment available and site needs. Therefore, a professional rigger must determine the rigging and lifting method to be used, and it is beyond the scope of this manual to specify rigging and lifting details. RIGGING The 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 3 on Page 11. 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 dimensions are given on pages 22 thru 40 as a guide in determining the clearances required for rigging. Add 6" (15 cm) to overall height for optional skidded unit. 10 JOHNSON CONTROLS

15 SECTION 2 - 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 chiller to its mounting position.) At this point units shipped dismantled should be assembled under the supervision of a Johnson Controls representative. If evaporator is to be field insulated, the insulation should be applied to the evaporator before the unit is placed in position while the unit is in the lift position. Be sure unit is properly supported. (Refer to Figure 3 on Page 11) LOCATING AND INSTALLING ISOLATOR PADS The isolator pad mounts are to be located as shown in Figure 4 on Page 12 (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" (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 recheck to see that it is level. CHECKING THE ISOLATION PAD DEFLECTION All isolation pads should be checked for the proper deflection while checking to see if the unit is level. Each pad should be deflected approximately 0.10 inches (2.5 mm) to 0.20 inches (5 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 evaporator shell under the compressor/motor assembly. Transverse alignment should be checked by placing a level on top of the shell end sheets. INSTALLING OPTIONAL SPRING ISOLATORS When ordered, 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 clear of the floor by the dimension shown in Figure 5 on Page 13 and Figure 6 on Page 14 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. PIPING CONNECTIONS After the unit is leveled (and wedged in place for optional 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 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 2 JOHNSON CONTROLS 15

16 Section 2 - installation bolts or coupling and checked for piping alignment. If any of the bolts are bound in their holes, or if the connection 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 WATER PIPING The evaporator and condenser liquid heads of chiller have nozzles which are grooved, suitable for welding 150 psig DWP flanges or the use of flexible couplings. Factory mounted flanges are optional. The nozzles and water pass arrangements are furnished in accordance with the job requirements (see Product Drawings) furnished with the job. Standard units are designed for 150 psig DWP on the water side. If job requirements 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 liquidcooled motor starter must be maintained above the dewpoint temperature in the equipment room to prevent condensing water vapor inside the starter cabinet. Therefore, an additional temperature-controlled throttle valve is needed in the COOLING TOWER FOR N1 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 methods, such as wells, bodies of water, and chilled water. The temperature control valve should be the type to open on increasing drive coolant temperature, fail-closed, and set for a temperature above dewpoint. It can be requested as factorysupplied on a chiller order by special quotation. Chilled Water Foreign 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 chiller must be very carefully cleaned before start-up.) If pumps are remotely installed from chiller, strainers should be located directly upstream of the chiller.

17 Section 2 - installation Condenser Water Circuit For proper operation of the unit, condenser refrigerant pressure must be maintained above evaporator 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 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 O1) condenser water temperature must be maintained equal to or slightly higher than the required minimum. Refer to Figure 7 on Page 16 for typical water piping schematic. Stop Valves Stop valves may be provided (by others) in the evaporator 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 Switches Thermal 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. Waterbox Drain and Vent Valves Drain and vent valves (by others) should be installed in the connections provided in the evaporator 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 waterbox insulation is applied. Tighten and torque to maintain between 30 and 60 ft. lbs. (41 and 81 N m) the nuts on the liquid head flanges. Gasket shrinkage and handling during transit cause nuts to loosen. If water 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 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 Johnson Controls representative: (1) the lubricant piping to oil sump and oil evaporator and system oil return connections using material furnished. Refer to Installation - Unit (Form N3). 2 JOHNSON CONTROLS 17

18 Section 2 - installation FOR N1 REFRIGERANT RELIEF PIPING Each unit is equipped with pressure relief valves located on the condenser and on the evaporator 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 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 intercept and permit clean out and to trap any vent stack condensation. The piping UST be arranged to avoid strain on the relief valves, using a flexible connection, if necessary. When installing relief piping an ANSI flange or a piping union must be used to make a servicable piping connection. Horizontal is-aligned Vertical Compressed Offset When installing relief piping there must NOT be any piping strain. Relief piping must be properly aligned and supported to eliminate any possible piping strain.

19 Section 2 - installation CONTROL PANEL POSITIONING On large YK chillers equipped with H9 and K1-K7 compressors, the control panel height can be adjusted. Chillers equipped with P and Q compressors the control panel height is NOT adjustable. 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. While supporting the control center, remove the hardware between the support arms and the evaporator. 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. SUPPORT ARS PANEL TRACK Figure 9 - CONTROL PANEL POSITIONING (H9, K1-K7) CONTROL WIRING LD03826 On units shipped disassembled, after installation of the control center, control wiring must be completed between unit components and control center, solid state starter, or variable speed drive, when used, using wiring harnesses furnished. Refer to Installation - Unit (Form N3). Field wiring connections for commonly encountered control modifications (by others) if required, are shown on Wiring Diagram Unit (Style G) Field Control odifications (Form PW4). POWER WIRING No deviations in unit wiring from that shown on drawings furnished shall be made without prior approval of the Johnson Controls representative. Chiller with Electro-echanical Starter A 115 volt single phase 60 or 50 Hertz power supply of 20 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. OIL PUP 3 PHASE STARTER Separate wiring or a fused disconnect switch should be supplied by the installer. Remote Electro-echanical starters for the chiller must be furnished in accordance with YORK Starter Specifications Product Drawing Form PA1 to provide the features necessary for the starter to function properly 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. 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 Johnson Controls representative. DO NOT cut wires to final length or make final connections to motor terminals or starter power input terminals until approved by the Johnson Controls representative. YK otors (Electro-echanical Starter) otor leads are furnished with a crimp type connection having a clearance hole for a 3/8" bolt, motor terminal lugs are not furnished. Refer to Wiring Labels in motor terminal box for hook-up to suit motor voltage and amperage for power wiring connections. 2 JOHNSON CONTROLS 19

20 Section 2 - installation Chiller with Solid State Starter or Variable Speed Drive A 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 (or an optional factory installed disconnect switch). See Field Wiring Diagram. 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 or Variable Speed Drive. INSULATION DO 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 minimum thickness to prevent sweating of 30 F (-1 C) surfaces should be furnished (by others) and applied to the evaporator shell, end sheets, liquid feed line to Tape Insulation to Filter Drier FOR N1 flow chamber, compressor suction connection, and evaporator 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 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 Installation Checklist and Request for startup, (Form CL1).
