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.

Remove the 2 screws which fix the indoor heat exchanger to the installation plate.

Disconnect the pipings. Place a plastic sheet under the drain pan to prevent from wetting the floor with remaining drain. If the drain hose is embedded in the wall, disconnect the drain hose beforehand. Carry out the removal work with 2 wrenches. When the pipings are disconnected, protect both the openings of pipe and unit from entering of moisture. Inserting a wooden base beneath the unit facilitates the removing work.

Remove the indoor unit from the installation plate.

Unfasten the hook of the piping fixture at the back of the indoor unit and pull out the piping.
