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.

Unscrew the flare nut for gas piping and liquid piping and disconnect both pipes.

Hold the indoor unit up with a piece of wood.
