Hot air does not fl ow out soon after 

 

the start of HEAT operation.

•   The air conditioner is warming up. You should wait for 

1 to 4 minutes. (The system is designed to start 
discharging air only after it has reached a certain 
temperature.)

 

The ON/OFF TIMER does not 

 

operate according to the settings.

•   Check if the ON/OFF TIMER and the WEEKLY TIMER 

are set to the same time.  
Change or deactivate the settings in the WEEKLY 
TIMER.

properly.

 

 No remote controller signals are displayed.

The outdoor fan rotates while the  

 

air conditioner is not in operation.

 

  After operation is stopped

•   The outdoor fan continues rotating for another 

60 seconds for system protection.

 

  While the air conditioner is not in operation

•   When the outdoor temperature is very high, the 

outdoor fan starts rotating for system protection.

 

The indoor unit gives out odour.

•   This happens when smells of the room, furniture, or 

cigarettes are absorbed into the unit and discharged 
with the air

fl

 ow.

  ( If this happens, we recommend you to have the 

indoor unit washed by a technician. Consult the 
service shop where you bought the air conditioner.)

 

HEAT operation cannot be selected, 

even though the unit is heat pump 
model.

• Check that the jumper (J8) has not been cut. If it has 

been cut, contact the service shop.
