Operating Recommendations
Here are a few recommendations that you should follow when 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 on 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 is selected.
If this happens:
◆ The heating operation is stopped.
◆ The Deice mode is triggered automatically
for about seven minutes.
No intervention is required from you; after
about seven minutes, the air conditioner starts
operating again normally.
High indoor and outdoor
temperatures
If both the indoor and outdoor 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, the air conditioner
starts up again automatically.
E-21
Temperature and Humidity Ranges
The following table indicates the temperature and humidity ranges within which the air conditioner can be used.
If the air conditioner is used at...
Then...
High temperatures
The automatic protection feature may be triggered and the air conditioner stopped.
Low temperatures
A water leak or some other malfunction may occur if the heat exchanger freezes.
High humidity levels
Water may condense on and drip from the surface of the indoor unit if it is used for long periods.
