Liebert XD Cooling Modules—Liebert XDO, Liebert XDV, Liebert XDH and Liebert XDCF

4.7.2Piping Connections to Liebert XDP or Liebert XDC Piping Installation for Hard Piped System

The assembly and connection means for piping in the Liebert XD system are similar to those used for conventional refrigeration systems. All piping should be installed with high-temperature brazed joints. Soft solder is not recommended. During brazing, the lines must be filled with flowing dry nitro- gen to prevent excessive oxidation and scale formation inside the piping. Prevailing good refrigeration practices must be employed for piping supports, leak testing, dehydration and charging. Failure to use good system practices may result in damage to the system. Refer to the ASHRAE refrigeration handbook for general good-practice refrigeration piping.

Follow all guidelines in 3.13 - Liebert XD Piping System Design and 3.14 - Liebert XD Piping Slope during installation.
