6.2.1 Piping Connections to Liebert XDP or Liebert XDC

Refer to site specific drawings for general locations of the piping connections. For Liebert XDV con-
nection locations, refer to Figures 1 and 24.
6.3 Connection Methods and Points
The assembly and connection means used for piping in the Liebert XD system are the same as those
used in conventional refrigeration systems. Observe all standard practices during installation and
startup to prevent damage and contamination. All piping must be ASTM Type "L" copper pipe.
For hard-piped Liebert XDVs, the supply piping connection is 1/2" OD copper pipe, and the return
piping connection is 5/8" OD copper. For Liebert XDVs with the pre-charged option, both supply and
return fittings are one-shot connections. These fittings contain pressurized R-134a refrigerant inside
the Liebert XDV.
