Operating Recommendations  
Here are a few recommendations that you should follow when 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:  
N The heating operation stops.  
N The defrost mode will be triggered automatically for 3 to  
14 minutes.  
No intervention is required ; after about 7 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 starts up again automatically.  
Cooling  
operation  
The indoor unit may not get the selected fan speed such as  
Medium and Low under cooling operation at very low outdoor  
temperatures for protecting the indoor unit from ice or frost.  
During Low fan speed operation, cooling performance will be  
reduced.  
If the room does not cool down when using Low fan speed  
operation, please adjust the indoor unit’s fan speed.  
E-9  
 
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 temperature  
The automatic protection feature may be  
triggered and the air conditioner stopped.  
Low temperature  
A water leakage or some other  
malfunction may happen if the heat  
exchanger freezes.

the surface of the indoor unit if it is used  
for a long periods.
