18 Installation 2.0 INSTALLATION Read this entire installation section before starting installation. This section details dimensional, electrical and piping information and specifications that affect the placement of the PFH unit in relation the connected evaporator unit, other outside units, barriers and walls. Be particularly mindful of service and airflow clearances and maximum equivalent piping distances and in elevation differences between PFH and connected evaporator unit. Consult and confirm applications with your Emerson Network Power representative when applications exceed any of these specifications. 2.1 Equipment Inspection When the unit arrives, inspect all items for any visible or concealed damage. Report any damage to the carrier immediately and file a damage claim; send a copy of the claim to Emerson Network Power or your local Emerson sales representative. If possible, maintain equipment and packaging until it is at the installation location. 2.2 Location Considerations To ensure an adequate air supply, locate all condensing units in a clean-air area, away from loose dirt and debris that can clog the coil. Avoid ground-level sites with public access or areas that are exposed to heavy snow accumulation. Locate unit to allow maximum security and maintenance accessibility. Do not locate condensing units near steam, hot air or fume exhausts. Do locate units at least 18 in. (457mm) from walls, obstructions or adjacent units. For multiple unit installations, space unit so that the hot condenser exhaust air is not directed toward the condenser air inlet of an adjacent unit. Install a solid base at least 2 in. (51mm) higher than the surrounding grade and 2 in. (51mm) larger than condensing unit base dimensions and capable of supporting the condenser s weight. 2

19 2.5 Piping Considerations Installation The Liebert Mini-Mate2, Liebert DataMate and the 3-ton Liebert Challenger 3000 split system units are designed with quick-connect fittings and are factory-charged to proper refrigerant levels. This permits connecting units without brazing inside critical spaces. These split systems require two refrigerant lines an insulated copper suction line and a copper liquid line between the evaporator and condensing units. The 8-ton Liebert Mini-Mate2 split system units will require four refrigerant lines between the evaporator and condensing units. Each refrigeration circuit will need one insulated copper suction line and one copper liquid line. Two methods exist for installing the copper suction and liquid lines: Using optional pre-charged line sets (for 1- to 3.5-ton R-407C model units only). Using optional Sweat Adapter Kit(s) and hard piping between units. NOTICE Risk of improper handling of refrigerant. Can cause environmental damage and violation of environmental regulations. Refrigerant must handled in accordance with all national, regional and local codes. NOTE Proper safety equipment and proper refrigeration tools are required in working with R-407C refrigerant. Check unit serial tag for correct refrigerant type before topping off or recharging a system. NOTE Refrigerant R-407C uses a POE (polyol ester) lubricant. The R-407C refrigerant must be introduced and charged from the cylinder only as a liquid. NOTE When installing field piping, care must be taken to protect all refrigerant lines from the atmosphere, especially when using refrigerants with POE oils. Do not allow the piping to stand open to air for more than 15 minutes. Units designed for R-407C have a compressor which contains POE oil that is very hygroscopic; that is, it quickly absorbs water from the air. The longer the compressor piping is left open to air, the harder it will be to fully evacuate. If left open too long, the POE oil may need to be replaced before achieving the required vacuum level. NOTE Complete all piping and evacuate lines before connecting quick connects when using an optional sweat adapter kit and field installed hard piping. Follow all proper brazing practices including a dry nitrogen purge to maintain system cleanliness Piping for Elevation Differences between PFH and Evaporator System sizes affect the maximum equivalent piping lengths and maximum relative elevation differences between evaporator and condensing unit mounting locations. See Table 5 for requirements. Traps in refrigerant piping are required when elevation differences exist between evaporator and condensing unit mounting locations. See Figure 12 for requirements. Table 6 should be used when traps are required with field-fabricated piping assemblies, to calculate equivalent pipe lengths to determine if installation will comply with Table 5 requirements. 14

NOTICE Table 7 Line Size, in. 3/8 liquid 5/8 or 7/8 suction Installation Risk of improper handling and installation of pre-charged lines. Can cause kinks and similar damage to lines. Care must be taken to prevent kinking the pre-charged lines for 1-ton and 3.5-ton units. Use tube benders and make all bends before making connections to either end of the precharged pipes. Coil any excess tubing in a horizontal plane with the slope of the tubing toward the condensing unit. Use a soft, flexible material to pack around the tubes when sealing openings in walls to prevent tube damage and to reduce vibration transmission Field-Fabricated Line Sets Refrigerant charge in Liebert pre-charged R-407C line sets Length, ft.

Use a flow of dry nitrogen through the piping during brazing to prevent formation of copper oxide scale inside the piping. Avoid soft solders such as 50/50 or 95/5. Use the sweat adapter kits to terminate the piping at each unit end. Consult factory representatives to obtain the proper sweat adapter kit. Table 8 has PFH unit connection sizes. Use Table 9 for recommended line sizes. Prevailing good refrigeration practices should be employed for piping supports, leak testing, evacuation, dehydration and charging of the refrigeration circuits. The refrigeration piping should be isolated from the building by the use of vibration-isolating supports. Use a soft, flexible material to pack around the tubes when sealing openings in walls to prevent tube damage and to reduce vibration transmission. Before connecting units together with field-fabricated piping, check for leaks and dehydrate the field piping as follows: 1. Pressurize the field piping to 150 psig (1034 kpa) using dry nitrogen with a trace of refrigerant. Check system for leaks with a suitable leak detector. 2. After completion of leak testing, release the test pressure (per local code) and triple evacuate the field piping to 250 microns or lower, breaking the vacuum between the first two evacuations with dry nitrogen. 3. After the third evacuation, verify 250 microns is maintained for at least one minute after the piping is isolated from the vacuum pump by a shutoff valve. Field piping is now ready to be installed between evaporator and condensing units. 16

23 2.5.4 Installation of Piping to Units NOTE When using hard piping, complete all piping and evacuate the lines before connecting quick-connects. Installation NOTE Liebert Challenger 5-ton evaporator includes a nitrogen holding charge only. This holding charge must be evacuated and unit placed in a 250 micron vacuum prior to connecting piping. See Table 12 for field charge required. Use caution when connecting the quick-connect fittings. Read through the following steps before making the connections. 1. Remove protector caps and plugs. 2. Carefully wipe coupling seats and threaded surfaces with a clean cloth. 3. Lubricate the male diaphragm and synthetic rubber seal with refrigeration grade oil. 4. Thread the coupling halves together by hand to ensure that the threads mate properly. 5. Tighten the coupling body hex nut and union nut with the proper sized wrench until the coupling bodies bottom out or until you feel a definite resistance. 6. Using a marker or pen, make a line lengthwise from the coupling union nut to the bulkhead. 7. Tighten the nuts an additional quarter turn; the misalignment of the lines shows how much the coupling has been tightened. This final quarter turn is necessary to ensure that the joint will not leak. Refer to Table 10 for torque requirements. 8. Add liquid refrigerant charge for any field-fabricated piping (refer to Table 11) and the 5-ton Liebert Challenger evaporator if used (refer to Table 12).

Check for proper operation of the system prior to replacing the outdoor unit. If this is not possible, at minimum perform a leak check to ensure that the components that remain (line set, evaporator) are leak tight. 2. Check for acid or contaminants in the mineral oil. 18

24 Installation Remove Existing Condensing Unit 1. Recover refrigerant in system using proper refrigeration practices. 2. Oil removal: The majority of the oil will be in the old condensing unit (compressor, condenser and receiver), which will be replaced with the new unit. 3. Remove high-voltage and low-voltage wiring. NOTE Wiring should be removed by a licensed electrician. Existing low-voltage wiring may have a 3-wire lead. A 4-wire lead is required for hot gas bypass control on the new condensing unit. 4. Cut the line set before the Aeroquip fittings entering the condensing unit. 5. Remove the existing filter drier in evaporator unit and discard. The filter drier may contain contaminants that can be released out of the drier because of the POE oil. Filter Drier Selection and Installation Recommended 1. Install a replaceable-core filter drier approved for POE oil. The existing drier must be removed. The replaceable core drier will not fit in the same location as the existing drier. 2. Ensure there is enough clearance for replacing cores when choosing a location. 3. Replace core a week after startup and inspect the removed replaceable core for contaminants to determine if another replacement is needed. (If the system experienced a burnout, shorter interval replacements will be needed.) Optional Install a new filter drier approved for POE oil in place of the existing one. Install the New Condensing Unit 1. Install a stub tube kit on the existing line set connecting to the new condensing unit. This kit is available from Emerson or your local Emerson representative. 2. Evacuate the evaporator-piping system twice to a minimum 250 microns, breaking the vacuum with dry nitrogen each time. 3. Evacuate a third time to 250 microns and verify the above levels are maintained for at least one minute after the unit is isolated from the vacuum pump by a shutoff valve. 4. Connect the condensing unit with the evaporator and piping (see Installation of Piping to Units). 5. Add enough R-407C refrigerant for the evaporator unit and line set. See Table 11 for line set charges required and Table 12 for standard evaporator units. If a non-standard evaporator was used, refer to evaporator unit serial tag for charge amounts and use 1 oz. (0.0283kg) R-407C for every 1 oz. (0.0283kg) R-22 used in old evaporator and piping. 19

25 2.5.6 General System Charge Requirements Installation Liebert split system units are designed with quick-connect fittings and are factory-charged to proper levels. Due to the wide range of operating ambients and sensitivity of the system components to charge level, the system charge must be maintained at recommended levels. If there is any doubt that the system has the correct refrigerant charge level, the correct procedure is to remove the entire system charge, evacuate the system and weigh in the recommended factory charge total for both units and any line sets or field piping. Tables 7, 8, 11 and 12 are included for field piping allowances, condensing unit charges, line sets and evaporator charges. Total refrigerant charge = evaporator + lines + condensing unit NOTE All condensing units and most evaporator units are fully charged with refrigerant. Some evaporator units are shipped from the factory with a nitrogen holding charge only. (Refer to evaporator serial tags.) If field-supplied refrigerant piping is installed, refrigerant must be added to the system. Refer to Figure 12 for field-supplied piping guidelines.

26 2.6 Electrical Connections Installation Each unit is shipped from the factory with all internal wiring completed. All power, control wiring and ground connections must be made in accordance with the National Electrical Code and local codes. Refer to equipment nameplate regarding wire size and circuit protection requirements. Refer to Figures 5, 7 and 8 and electrical schematic (reference Figures 9 through 11) when making connections. A manual electrical disconnect switch should be installed within 5 feet (1.6m) of the unit in accordance with codes.! WARNING Risk of electric shock. Can cause injury or death. Disconnect all local and remote electric power supplies before working within. Use a voltmeter to be sure power is turned off before making any electrical connections. NOTICE Risk of incorrect phase sequencing. Can cause equipment damage. Three-phase power must be connected to the unit line voltage terminals in proper sequence so that the scroll compressor rotates in the correct direction. The three-phase scroll compressor requires proper phasing to ensure correct motor rotation. The component connections have been phase synchronized at the factory. Power phasing should be changed only at the line voltage supply to the unit. To change phasing, switch any two power leads to the unit. Observe system pressures to determine whether the unit is operating properly. NOTICE Risk of compressor slugging. Can cause equipment damage. Apply power to condenser 8 hours before operating the system. This time is required to allow liquid refrigerant to be driven out of the compressor. This is especially important at low ambient temperatures. The compressor crankcase heater is energized as long as power is supplied to the unit.

Refer to Figures 5, 7 and 8 and to unit electrical schematic and Figures 9 through

27 4.4 Field Charge Verification Maintenance An integral sight glass is provided with the receiver to assist in field charge verification. During charge verification set the control temperature down to keep the system running. If the system is equipped with hot gas bypass, de-energize it by removing power from the hot gas solenoid valve coil. To remove power, disconnect the solenoid leads from the unit contactor in the electric box (refer to specific unit schematic; reference Figures 7 through 10). When charge verification has been completed, replace and secure all wire connections and covers. During operation at design ambients (95 or 105 F; 35 or 41 C) the charge level will be above the sight glass in the receiver. If levels are below the sight glass an undercharge condition is likely. If levels are above the sight glass and higher discharge pressures than normal are observed an overcharge condition may be likely. However, verify that other high discharge pressure causes such as dirty coil and restricted airflow are not responsible before removing charge. At temperatures below design ambient, refrigerant backs into the condenser coil and the level in the receiver will drop below the sightglass. If you are trying to verify charge level at lower ambients, block the condenser coil to maintain 230psig (1585kPa) discharge pressure to ensure the head pressure control valve is closed. At these conditions the charge level should be above the sight glass in the receiver. NOTE The 5-ton high ambient, 5-ton Quiet-Line and 8-ton models consist of two condenser coils and two receivers. When restricting airflow on these units, the coils should be blocked off proportionally. If one coil is restricted significantly more than the other, liquid can remain in the restricted coil causing lower levels in the receivers. The receiver liquid level should be above the sight glasses in both receivers. There may be some variation in charge level between the two receiver sight glasses due to piping and assembly variations. When adding charge, determine which receiver level is lower and use that sight glass to gauge charge level. NOTE If no level is visible in the sight glass, add charge until the level is in the middle of the sightglass. Check the discharge pressure during this procedure and adjust coil restrictions to maintain 230 psig (1585 kpa). Once the charge is in the middle of the sightglass, add additional system charge per Table 22. After charging, unblock the coil and allow the unit to operate normally. After conditions have stabilized, restrict the coil if required to maintain 230psig (1585kPa) discharge pressure and verify that the charge level is above the sight glass.
