6.10Disconnecting a Liebert XDV With Liebert Flex Pipe From a Liebert XD System

! CAUTION

Risk of sudden discharge of pressurized refrigerant. Can cause equipment damage or injury.

Do not disconnect threaded refrigerant couplers at the unit cabinet end without relieving system pressure. Reclaim any refrigerant during removal of unit from system.

NOTICE

Before uninstalling a Liebert XDV with Liebert Flex Pipe from the prefabricated piping mains: With the fans running, close the supply service valve, wait approximately

two minutes, then close the return service valve.

Removing a Liebert XDV from above a cabinet will require two people. Read all instructions before beginning.

Tools Required

•Two adjustable wrenches, maximum adjustment size of 2-1/2 inches

•Two ladders

•Phillips head #2 screwdriver

•Lift mechanism, if the Liebert XDV is suspended above cabinet

1.Ensure the Liebert XDV fan switches are both On and the fans are operational.

2.Close the service valve in the supply line to the Liebert XDV (smaller coupler).

3.With the Liebert XDV fans running, wait two minutes.

4.Close the service valve in the return line to the Liebert XDV (larger coupler).

5.Turn the fan power switches to the Off position. Once the fan switches are turned Off, unplug the power cords from their power source.

6.Locate and have at the ready the caps and plugs for both ends of the supply and return couplers.

7.Loosen the female supply coupler from the male supply coupler (smaller coupler). This requires two adjustable wrenches. Refer to Figure 29.

8.The Liebert XDV side of the female coupler must be held stationary while the collar on the coupler is being loosened. Refer to Figure 29.

9.Disconnect the coupler.
