Do not turn OFF power immediately after the unit

Explanation of HEATING operation
DEFROST operation
As the frost on the coil of an outdoor unit increase, heating
effect decreases and the system goes into DEFROST
operation.
The FAN operation stops and the DEFROST lamp of the
indoor unit goes on.
After about 4 to 12 minutes of DEFROST operation, the
system returns to HEATING operation.
Heating capacity and outdoor air temperature
Heating capacity drops as outdoor air temperature lowers.
If feeling cold, use another heater at the same time with
this air conditioner.
Hot air is circulated to warm the room. It will take some
time from when the air conditioner is rst started until the
entire room becomes warm. The internal fan automatically
turns at low speed until the air conditioner reaches a
certain temperature on the inside.
If hot air accumulates on the ceiling and feet are left feeling
cold, it is recommended to use a circulator. For details,
contact the place of purchase.
