Operating Recommendations
Here are a few recom m endations that you should follow w hen using
your air conditioner.
Topic
Recommendation
Heating performances
The heat pump inside the air conditioner
absorbs heat from outside air and brings it
indoors. If the temperature of the outside air
drops, the air conditioner will heat less. If you
find that the room is not warm enough, use an
additional heating appliance.
Warm air circulation
The air conditioner circulates warm air to heat
your room; as a result, some time will be
required after starting the air conditioner to
warm the entire room. If necessary, set the air
conditioner going a short time before you wish
to use the room.
Frost
When outside temperatures are low and
humidity is high, frost may form in the outdoor
unit when heating with your air conditioner.
If this happens:
◆ The heating operation is stopped.
◆ The Deice mode is triggered automatically
for about seven minutes
◆ The OPERATION indicator on the
indoor unit lights up red
No intervention is required from you; after
about seven minutes, the air conditioner starts
operating again normally.
High indoor and outdoor If both the indoor and outdoor temperatures
temperatures
are high and you select the Heat mode, the
outdoor unit’s fan and compressor may stop at
times. This is normal; simply wait until the air
conditioner switches on again.
Power failure
If a power failure occurs when the air
conditioner is operating, the unit is switched off.
When the power returns, you must press
(On/Off) to restart it.

High humidity levels
The automatic protection feature may

A water leakage or some other

is used for long periods.
