6.7.5Connect a Liebert XDR with Liebert XD Flex Pipe to a Liebert XD System

NOTE

Check the entire system for leaks before connecting the Liebert XDR with Liebert XD Flex Pipe to the prefabricated piping mains.

Read all instructions before beginning installation.

NOTICE

Risk of refrigerant loss. Can cause environmental pollution and equipment malfunction.

Before connecting the Liebert XDR with Liebert XD Flex Pipe to the prefabricated piping mains, check the whole system for leaks.

Check the Liebert XDR to ensure that the module has no refrigerant leaks. Read all instructions before beginning installation.

Tools Required

•One adjustable wrench with a maximum adjustment size of 2 inches

•One torque wrench, half-inch drive

•Crowsfoot (supplied with Liebert XDP and Liebert XDC)

•Liebert XDP or Liebert XDC user manual

NOTE

This operation requires two or more people.

1.Determine the port location of the supply and return piping overhead.

2.Make sure the service valve for each port is closed

3.Remove caps from only the required ports. Do not remove caps from the unused ports.

4.Remove the pipe plugs that are supplied on the Liebert XD Flex Pipe.

5.Inspect both halves of the coupling and remove any foreign contamination from the sealing surfaces and threads before connecting the fittings.

6.Determine the coupling size by locating the number scribed on the Liebert XD Flex Pipe coupling. See Figure 23.
