In pump-down work, be sure to stop the compressor before disconnecting the refrigerant pipe. If the refrigerant pipe is disconnected with the compressor operating and the stop valve open, air may be sucked in and may generate an over-pressure in refrigeration cycle, thus resulting in pipe rupture or accidental injury.

When removing or reinstalling the indoor heat exchanger, be sure to wear gloves or wrap the indoor heat exchanger with cloths. (You may be injured by the fins.)

Caution: Be sure to conduct pump down operation before disassembling the refrigerant pipe.

If the refrigerant leaks, repair the spot of leaking, then collect all refrigerant from the unit. After conducting vacuum drying, recharge proper amount of refrigerant.

From the viewpoint of global environmental protection, make sure to use a vacuum pump for air purging.

Pull out and disconnect the drain hose.

Wrap the open ends of the drain hose with plastic sheets to prevent water dripping.

Unscrew the flare nuts for gas piping and liquid piping.
