Trouble Shooting

• These cases are not troubles.
  The following cases are not air conditioner troubles but have some reasons. You may just continue using it.

Case	Explanation
Operation does not start soon. ●  When ON/OFF button was pressed soon after operation was stopped. ●  When the mode was reselected.	●  This is to protect the air conditioner. You should wait for about 3 minutes.
The outdoor unit emits water or steam.	■  In COOL or DRY mode ·    Moisture in the air condenses into water on the cool surface of outdoor unit piping and drips.
Mists come out of the indoor unit.	■  This happens when the air in the room is cooled into mist by the cold air flow during cooling operation.
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 flow. (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.)
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 out door fan starts rotating for system protection.
The operation stopped suddenly. (OPERATION lamp is on)	■  For system protection, the air conditioner may stop operating on a sudden large voltage fluctuation. It automatically resumes operation in about 3 minutes.

• Check again
  Please check again before calling a repair person.

Case	Check
The air conditioner does not operate. (OPERATION lamp is off)	●  Hasn’t a breaker turned OFF or a fuse blown? ●  Isn’t it a power failure? ●  Are batteries set in the remote controller? ●  Is the timer setting correct?
Cooling effect is poor.	●  Are the air filters clean? ●  Is there anything to block the air inlet or the outlet of the indoor and the outdoor units? ●  Is the temperature setting appropriate? ●  Are the windows and doors closed? ●  Are the air flow rate and the air direction set appropriately?
Operation stops suddenly. (OPERATION lamp blinks.)	●  Are the air filters clean? ●  Is there anything to block the air inlet or the outlet of the indoor and the outdoor units? Clean the air filters or take all obstacles away and turn the breaker OFF. Then turn it ON again and try operating the air conditioner with the remote controller. If the lamp still blinks, call the service shop where you bought the air conditioner.
An abnormal functioning happens during operation.	●  The air conditioner may malfunction with lightening or radio waves. Turn the breaker OFF, turn it ON again and try operating the air conditioner with the remote controller.

• Call the service shop immediately.
