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 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 units 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,
