All evaporator units and condensing units are fully factory-charged with refrigerant. If field-supplied refrigerant piping is

installed, refrigerant must be added; refer to Table 12 to determine the additional charge.

Quick Connect Fittings

NOTE

When hard piping is used, complete all piping and evacuate lines before connecting quick connects.

Be especially careful 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 refrigerant oil.

4. Thread the coupling halves together by hand to insure that the threads mate properly.

5. Tighten the coupling body hex nut and union nut with the proper size wrench until the coupling bodies “bottom out” or until a definite resistance is felt.

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 insure that the joint will not

leak. Refer to Table 13 for torque requirements.

5.4.4 Electrical Connections

Each unit is shipped from the factory with internal wiring completed. Refer to electrical schematic when making connections. Electrical connections to be made at the installation site are:

• Power supply to each ceiling unit.

!

WARNING

Arc flash and electric shock hazard. Disconnect all electric power supplies and wear protective equipment per NFPA 70E before working within electric control enclosure. Failure to comply can cause serious injury or death.

The Liebert microprocessor control does not isolate power from the unit in the Unit Off mode.

Some internal components require and receive power even during the Unit Off mode. The line side of the disconnect switch on the front of the unit contains live high voltage. The only way to ensure that there is NO voltage inside the unit is to install and open a remote disconnect switch and check the internal power supply wires with a voltmeter.

• Control wiring between the evaporator unit and the condensing unit, if applicable.

• Control wiring between the control panel (wallbox) and the evaporator unit control board.
