6.6.1Refrigerant Charge—Pre-Charged Option

Liebert XDVs with the pre-charged option are equipped with one-shot connections on the supply and return fittings. These contain a charge of R-134a refrigerant under pressure within the unit. This charge must not be vented.

Do not remove the pipe caps or plugs before the unit is ready for connection to Liebert XD Piping. Do not disconnect one-shot connections after they have been connected.

6.7Field Installation of Liebert Flex Pipe Kit on Liebert XDV

If you are not performing a service installation or a field-retrofit, skip this section and proceed with the instructions in 6.8 - Connecting Liebert XD Flex Pipe to Liebert XDV Modules.

Liebert Flex Pipe kits are available in lengths of 4, 6, 8 and 10 feet (1.2, 1.8,2.4 and 3 meters). Connec- tion style to the unit end may be straight or 90 degrees. Connection to the prefab piping assembly is a threaded coupler. For data on acquiring the correct kit for your installation, see Table 7.

6.8Connecting Liebert XD Flex Pipe to Liebert XDV Modules

1.Remove the caps on the supply and return lines on the top of the Liebert XDV.

2.Lubricate the threads, diaphragm and O-ring with one or two drops of mineral oil.

3.Connect the line-set coupling finger-tight.

4.Make sure the Schrader valve is properly oriented; refer to the label on the top of the Liebert XDV.

5.Hold the backup hex nut with a wrench while tightening the swivel nut.

6.Tighten the swivel nut on the female coupling until it is seated or a definite resistance is felt.

7.Once a definite bottoming resistance is felt (as in metal to metal), place a mark lengthwise from the swivel nut to the backup hex and tighten the swivel nut on the female coupling an additional 1/4 turn.

8.Tighten both the supply fittings and the return fittings to 35-45ft/lb (47-61Nm).

9.Mark the female and male coupler with for future reference.
