Case Description / what to check
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.
Air does not come out.
„ In HEAT operation
• The air conditioner is warming up. Wait for about 1 to 4 minutes.
• During defrosting operation, hot air does not flow out of the indoor unit.
„ When the air conditioner operates immediately after the circuit breaker is turned on
• The air conditioner is preparing to operate. Wait for about 3 to 20 minutes.
The heating operation stops suddenly
and a flowing sound is heard.
• The system is taking away the frost on the outdoor unit.
You should wait for about 4 to 12 minutes.
The outdoor unit emits water or
steam.
„
In HEAT mode
• The frost on the outdoor unit melts into water or steam when the air conditioner is in
defrost operation.
„
In COOL or DRY mode
• Moisture in the air condenses into water on the cool surface of outdoor unit piping and drips.
Mist comes 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 30 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 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.
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 (Heating) effect is poor.
• Are the air filters clean?
• Is there anything blocking the air inlet or the outlet of the indoor and the outdoor units?

Operation stops suddenly.
(OPERATION lamp flashes.)
• Are the air filters clean?
• Is there anything blocking 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.
• Are operation modes all the same for indoor units connected to outdoor units in the
multi system?
If not, set all indoor units to the same operation mode and confirm that the lamps blink.
Moreover, when the operation mode is in “AUTO”, set all indoor unit operation modes to
“COOL” or “HEAT” for a moment and check again that the lamps are normal.
If the lamps stop blinking after the above steps, there is no malfunction.
