Heating operation
Since the heating operation is performed by
taking the heat from outdoor into the room,
the heating capacity decreases as the outdoor
temperature lowers. If the room is not heated
sufficiently, it is recommended to use other
heating appliance at the same time.
Since the air conditioner heats the whole room
by circulating hot air, it takes some time to
heat the entire room completely.
If the outdoor unit gets frosted during heating
operation, the heating capacity is decreased.
In this case, the unit starts defrosting
operation.
No hot air comes out of the indoor unit during
defrosting operation.

Recommended temperature
Cooling : 26˚C-28˚C (79˚F~82˚F)
Five levels of airflow rate setting
from " " to " " plus " " are available.
Heating : 20˚C-22˚C (68˚F~72˚F)
When the unit runs in the cooling or heating mode at a low airflow rate, the cooling or heating effect
may be insufficient.
