TROUBLE SHOOTING
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.
Hot air does not flow out soon after the
start of heating operation.
•
The air conditioner is warming up.
You should wait for 1 to 4 minutes.
Makes a noise.
■
Clicking sound can be heard either when the unit is running or stopped
•
This is either the sound of the valves regulating the refrigerant or the electrical parts working.
■
Sound of running water
•
Refrigerant is flowing through the air conditioner.
■
Blowing sound
•
The flow of refrigerant through the air conditioner is switching.
■
Creaking sound
•
The air conditioner itself is expanding or shrinking due to a change in the humidity.
■
Clopping sound
•
Can be heard coming from inside the air conditioner when the ventilator is on and the room
is shut. Open a window or turn off the ventilator.
■
Clicking sound can be heard either when the unit is running or stopped
•
This is the sound of the electrical parts working when the front panel opens or closes.
■
Blowing, cracky or burning sound
•
This is the sound of streamer discharging.
Fizzes during HUMIDIFYING or
VENTILATING operation.
•
This is the sound of humidified or ventilated air being discharged.
•
The operation noise may change depending on the outdoor temperature and humidity.
Makes a sound during HUMIDIFYING
operation.
■
Operation noise changes
•
This is because the fan for humidification moves or stops.
The indoor unit makes a noise even after
HUMIDIFYING operation is stopped.
•
The fan for humidification rotates for about 3 minutes after the operation stops for product pro-
tection.
Units stops during HEATING and the
sound of running water can be heard.
•
The frost on the outdoor unit is being removed. You should wait for about 3 to 10 minutes.
The outdoor unit emits water or steam.
■
In HEATING operation
•
The frost on the outdoor unit melts into water or steam when the air conditioner is in defrost operation.
■
In COOLING operation
•
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.
•
This is because moisture on the heat exchanger evaporates when “SARARA” DRYING opera-
tion is run after COOLING or DRY COOLING operation.
The indoor unit gives out odor.
•
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 odor may be captured. Stop the “URURU” HUMIDIFYING operation to eliminate
the cause of odor.
Cold air blows at the start of “SARARA”
DRYING operation.
•
This is because the air conditioner is not warmed up.
The outdoor fan rotates while the air con-
ditioner 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 operation stopped suddenly.
(Multi-colored indicator lamp is on.)
•
For system protection, the air conditioner may stop operating on a sudden large voltage fluctu-
ation. It automatically resumes operation in about 3 minutes.
Unit stops suddenly (when in ON TIMER
mode).
•
Reserving the on timer will cause the unit to start running up 1 hour before, in order to make
sure the temperature reaches the temperature set on the remote controller by the set time.
Using the remote controller during this time (other than the operation/stop button) will stop the
unit. Restart the unit with the remote controller.
Unit operates even though the multi-
colored indicator lamp is off.
•
The multi-colored indicator lamp will go off if “Monitor OFF” is set using the remote controller.
Unit continues to operate even after
“SARARA” DRYING, DRY COOLING or
COOLING operation is stopped.
•
The MOLD PROOF operation will start. (If you don’t want it, set to “MOLD PROOF OFF” using
the remote controller. (page 15.))
Room lamp flickers during HUMIDIFYING
operation.
•
It might happen the flickers of lighting in the case of insufficient power supply.
