6.7Field Installation of Liebert XD Flex Pipe Kit on Liebert XDR

If you are not performing a service installation or a field-retrofit, skip this section and proceed with the instructions in 6.7.2 - Connect a Liebert XDR with One-Shot Couplings to Liebert XD Flex Pipe.

Liebert XD Flex Pipe kits are available in lengths of 4, 6, 8 and 10 feet (1.2, 1.8, 2.4 and 3 meters). Connection style to the module end may be straight or 90 degrees with one-shot or removable cou- plings. Connection to the prefab piping assembly is a threaded coupling. For data on acquiring the correct kit for your installation, see Table 8.

The Liebert XD Flex Pipe should be connected to the Liebert XD module then to the header system to ease installation and prevent twisting the flex pipe.
