Since this air conditioner utilizes outside air for heating,
its heating performance deteriorates as outside tempera-
ture decreases.
(Due to heat pump system)
In that case, use another heating appliance.

Defrosting

This appliance may start defrosting operation to melt
frost formed in the outdoor unit.

‘‘DRY’’ operation

Once the room temperature reaches the level that was
set, the outdoor unit repeats the cycle of turning on and
off automatically.

When the outdoor unit is turned off, the indoor unit fan
will stop, too.
(To prevent the humidity in the room from rising again)

When the room temperature is more likely to reach the
level that was set, the fan speed is set to ‘‘breeze’’ (light
wind) automatically.

‘‘DRY’’ operation is not possible if the outdoor tempera-
ture is 15 °C or less.

Should the power failure occurs while the
unit is running
When the unit automatically resumes operation after
temporary power failure, it uses the same settings before
the power was cut off.
