• This is the case immediately after the main
power supply switch is turned on.
This means that the remote controller is in
normal condition. This continues for one min-
ute.
12.The compressor or fan in the outdoor unit
does not stop.
• This is to prevent oil and refrigerant from
remaining in the compressor. The unit will
stop after 5 to 10 minutes.
13.Hot air is emitted even though the unit is
stopped.
• Hot air can be felt when the unit is
stopped.
Several different indoor units are being run on
the same system, so if another unit is running,
some refrigerant will still flow through the unit.
14.Does not cool very well.

the room temperature as little as possible.
Refer to page 7.
15.The indoor fan may rotate while the unit
stops.
• The fan rotates even if the operation is
stopped with the remote controller.
As the system operates as an all-in-one air-
conditioner and refrigerator, the fan works to
prevent oil and refrigerant from accumulating
on the air conditioner during operation of the
showcase.
