Operating Recommendations  
Here are a few recommendations that you should follow when using your air conditioner.  
Topic  
Recommendation  
Heating performances The heat pump function of the air conditioner absorbs heat 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.  
Warm air circulation  
The air conditioner circulates warm air to heat your room. It will take some time to warm the  
air in your room entirely after the air conditioner turns on. Therefore, turn the air conditioner on  
in advance.  
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 10 minutes.  
  
The steam produced on the outdoor unit in the defrost mode is safe.  
No intervention is required ; after about ten minutes,the air conditioner operates again normally.  
If both indoor and outdoor temperatures are high and the air conditioner is running at HEAT  
High indoor and  
outdoor temperatures 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 while the air conditioner is operating, the unit will be switched off.  
When the power returns, the air conditioner starts up again automatically.  
Protection mechanism When the air conditioner is started immediately after being plugged in or stopped, the normal  
operation starts up after 3 minutes for the reason of protection.  
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 the protection of the indoor unit from ice  
or frost.  
During Low fan speed operation, cooling performance will be reduced. If the room does not be  
cooled down when using Low fan speed operation, please adjust the indoor unit’s fan speed.  
E-24
