Perform the following procedures to collect the refrigerant when
moving the indoor unit or the outdoor unit.

When the switch is pressed while the compressor is in opera-
tion, PUMP DOWN operation starts automatically.
When the switch is pressed while the compressor is in stop,
the compressor starts to operate automatically, and then move
