■ Freeze prevention
During COOL or DRY operation, freezing is detected and
operation is stopped when the temperature of the indoor heat
exchanger matches the conditions below.
1
Freeze-prevention operation is engaged when the
temperature of the indoor heat exchanger is below 6°C.
2
Restart after freeze-prevention operation occurs when the
temperature of the indoor heat exchanger reaches 8°C or
above.
a
area: Automatic capacity control
b
When the temperature drops below Point A, the operation
frequency is reduced by a certain proportion.
c
area: Frequency increase is prohibited.
d
When the temperature reaches Point C or above, freezing
prevention is ended and control is the same as in the
a
area.
* When the temperature drops to below 2°C (continuously for 2
minutes or longer), the compressor stops.
Once the freeze condition is detected, the air conditioner will
work less than the maximum frequency until it is turned off.

marked “A” on the remote controller.
2
Insert dry-cell batteries into the remote controller and press
the ACL button. Then attach the cover.
3
Open the air intake grille on the indoor unit, and move the
operation switch to the DEMO position.
4
Press the ON/OFF operation button on the remote
controller. Check that the “beep” signal-received sound is
heard from the indoor unit.
