WHEN YOU THINK THAT TROUBLE HAS OCCURRED

Symptom Explanation & Checkpoints
Indoor Unit
The unit cannot be operated. •  Is the breaker turned on?

 

 

•  Is the power supply plug connected?

•  Is the ON timer set? Page 8

The horizontal vane does not move. •  Are the horizontal vane and the vertical vane

 

 

installed correctly?

•  Is the fan guard deformed?

•  When the breaker is turned on, the horizontal vanes’ position will be reset in about a minute. After the reset has been completed, the normal horizontal vanes’ operation resumes. The same is true in the emergency cooling operation.

The unit cannot be operated for

 

 

about 3 minutes when restarted.

•  This protects the unit according to instructions

 

 

from the microprocessor. Please wait.

Mist is discharged from the air

 

 

the outlet of the indoor unit.

•  The cool air from the unit rapidly cools moisture in the air inside the room, and it turns into mist.
The swing operation of the HORI- ZONTAL VANE is suspended for a while, then restarted. •   This is for the swing operation of the HORIZON- TAL VANE to be performed normally.
When SWING is selected in COOL/DRY/FAN mode, the lower horizontal vane does not move. •  It is normal that the lower horizontal vane does not move when SWING is selected in COOL/ DRY/FAN mode.
The airflow direction changes

 

 

during operation.

The direction of the horizontal vane cannot be adjusted with the remote controller.

•   When the unit is operated in COOL or DRY mode if the operation continues with air blowing down for 0.5 to 1 hour, the direction of the airflow is automatically set to an upward position to prevent water from condensing and dripping.

 

 

•   In the heating operation, if the airflow tem- temperature is too low or when defrosting is being done, the horizontal vane is automatically set to a horizontal position.

The operation stops for about 10 minutes in the heating operation. •  Outdoor unit is in defrost.

 

 

Since this is completed in max. 10 minutes, please wait. (When the outside temperature is too low and humidity is too high, frost is formed.)

The unit starts operating by itself when the main power is turned on, but hasn’t received a sign from the remote controller. •     These models are equipped with an auto restart function. When the main power is turned off without stopping the unit with the remote controller and is turned on again, the unit starts operation automatically in the same mode as the one set with the remote control- later just before the shutoff of the main power.

 

 

Refer to the “Auto restart function”. Page 10

The two horizontal vanes touch each other. The horizontal vanes are in an abnormal position. The horizontal vanes do not return to the correct “close position”. Perform one of the following:

 

 

•  Turn on and on the breaker. Make sure the hori-

zontal vanes move to the correct “close position”.

•  Start and stop the emergency cooling operation and make sure the horizontal vanes move to the correct “close position”.

The indoor unit discolors over time. •     Although plastic turns yellow due to the influence of some factors such as ultraviolet light and temperature, this has no effect on the product functions.
Multi-system
The indoor unit which is not operating becomes warm and a sound, similar to water flowing, is heard from the unit. •  A small amount of refrigerant continues to flow into the indoor unit even though it is not operating.
When the heating operation is selected, the operation does not start right away. •  When the operation is started during defrosting of the outdoor unit is done, it takes a few minutes (max. 10 minutes) to blow out warm air.
Outdoor Unit
The fan of the outdoor unit does not rotate even though the compressor is running. Even if the fan starts to rotate, it stops soon. •     When the outside temperature is low during cooling operation, the fan operates intermittently to maintain sufficient cooling capacity.
Water leaks from the outdoor

 

 

unit.

•     During COOL and DRY operations, pipe or pipe connecting sections are cooled and this causes water to condense.

 

 

•     In the heating operation, water condensed on the heat exchanger drips down.

•     In the heating operation, the defrosting operation makes ice forming on the outdoor unit melt and drip down.

White smoke is discharged from

 

 

the outdoor unit.

•    In the heating operation, vapor generated by the

 

 

the defrosting operation looks like white smoke.
