Refer to site specific drawings for general locations of the piping connections. These drawings should
specify where the piping connects to the XDO (top, front and side).
7.1 Connection Methods and Points
The assembly and connection means used for piping in the 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. Pipe used should be copper type ACR or clean Type L.
Supply piping connection is 1/2" OD copper pipe, and return piping connection is 7/8" OD copper.
For ease of connection, the XDO offers supply and return piping access on the top or through the front
or either side (see Figure 22 ). Piping connections extend through the XDO’s top, the most frequently
used access point. Should access from another direction be required, the factory-installed pipes can be
shortened and elbows installed inside the unit to accommodate the alternate entrances. To locate the
side and front entrances, see Figures 23 and 24 .
