Operating Recommendations
Here are a few recommendations that you should follow w hen operating
your air conditioner.
Topic
Recommendation
Heating
The heat pump function of the air conditioner absorbs heat
performances from outside air and brings it indoors. As the temperature of the
outside air drops, the heating performance of air conditioner will
decrease. If you find that the room is not warm enough, using
an additional heating appliance is recommended.
Frost
When outside temperature is low but humidity is high,
frost may form on the outdoor unit at HEAT mode.
If this happens:
◆◆The heating operation stops.
◆◆The defrost mode will be triggered automatically for about ten
minutes.
No intervention is required ; after about ten minutes, the air
conditioner operates again normally.
High indoor
and outdoor
If both indoor and outdoor temperatures are high and the air
conditioner is running at HEAT mode, the outdoor unit’s fan
temperatures 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 while the air conditioner is operating,
the unit will be switched off. When the power returns, the air
conditioner restarts in the previous operation mode.
