assembly are secure and according to specifications.

___ 4. For Liebert XDH units with coupler option: Check for holding charge of R-134a.

___ 5. Low voltage wiring to optional condensate detection on the Liebert XDH.

___ 6. Piping from Liebert XDP to Liebert XDH, with isolation valves piped to each Liebert XDH.

___ 7. Piping insulated.

___ 8. Start the Liebert XDH to ensure proper operation (see 8.1 - Start the Liebert XDH).

___ 9. Shut down the Liebert XDH.

7.2 Charging with Refrigerant and Starting the Liebert XD System
