connections are tight.
(3) The protective spacers for the compressor used for
transportation have been removed. If not, remove them
now.
(4) The transportation pads for the indoor fan have been
removed. If not, remove them now.
(5) The power has been supplied to the unit for at least 5
hours before starting the compressor. The bottom of
the compressor should be warm to the touch and the

10-2. Caution

●
This unit may be used in a single-type refrigerant
system where 1 outdoor unit is connected to 1 indoor
unit, and also in a system where 1 outdoor unit is
connected to multiple indoor units (maximum 4).
* If multiple indoor units are used, also refer to "10-8. System
Control".
