6.7.7Disconnecting the Liebert XD Flex Pipe from the Liebert XDR

NOTICE

Risk of improper reuse of Liebert XD Flex Pipes with one-shot connections. Can cause refrigerant leaks.

Liebert XD Flex Pipes with one-shot connections must not be removed from the Liebert XDR unless they are being replaced with Liebert XD Flex Pipes with one-shot couplings. Do not reuse Liebert XD Flex Pipes with one-shot connections. Reuse may result in refrigerant leaks.

Tools Required

Two adjustable wrenches with a maximum adjustment size of 2 inches

1.Reclaim the refrigerant in the Liebert XD Flex Pipe and in the module by attaching a refrigerant reclaim device to the Schrader valve. For help finding the Schrader valve, see Figures 14, 17 and 21.

2.Hold the Liebert XD Flex Pipe so it does not rotate.

For the Liebert XD Flex Pipe with one-shot couplings, additionally, hold the brass body of the cou- pling so it does not rotate while loosening the couplings. Failing to do so may cause damage.

3.Loosen the Liebert XD Flex Pipe coupling from the module with a wrench.

4.Replace the dust plug on the Liebert XD Flex Pipe.

5.Replace the dust cap on the Liebert XD module.

6.Lay the Liebert XD Flex Pipe with removable couplings aside where it will not be damaged. Discard or recycle the one-shot Liebert XD Flex Pipes.

NOTICE

Risk of permanent damage to the Liebert XD Flex Pipes. Do not fold or bend pipe tightly.

6.7.8Removing the Liebert XDR from a Cabinet

! WARNING

Risk of 130-pound (59 kg) module falling. Can cause equipment damage, personal injury or death.

Removing a Liebert XDR from above a cabinet will require two properly trained and qualified people. Read all instructions before beginning.

1.Reinstall the four removable installation handles.

2.Loosen the bolts holding the Liebert XDR on the cabinet.

3.With the help of another person, lift the Liebert XDR from the cabinet or hanging bracket onto a stable surface.
