The unit cannot be operated.

· Is the breaker turned on? · Is the power supply plug connected?
· Is the ON timer set? Page 9

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 completed, the normal horizontal vanes’ operation resumes. The same is true in the emergency cooling operation.

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 upward position to prevent water from condensing and dripping. · In the heating operation, if the airflow temperature is too low or when defrosting is being done, the horizontal vane is automatically set to 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 operation by
itself when the main power is turned on, but hasn’t received 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 controller just before the shutoff of the main power.
Refer to “Auto restart function”. Page 11

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 off 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”.

In COOL/DRY mode, when the · When the room temperature deviates from the
room temperature reaches near set temperature, the indoor fan starts running

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.

The operation indicator lamp is dim. The unit does not beep.
Multi system

· Is the NIGHT MODE operation set? Page 9

The indoor unit which is not operating becomes warm and a sound, similar to water flowing, is heard from the unit.
When heating operation is selected, operation does not start right away.
Outdoor Unit

· A small amount of refrigerant continues to flow into the indoor unit even though it is not operating.
· When operation is started during defrosting of outdoor unit is done, it takes a few minutes (max. 10 minutes) to blow out warm air.

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. Water leaks from the outdoor unit.
White smoke is discharged from the outdoor unit.

· When the outside temperature is low during cooling operation, the fan operates intermittently to maintain sufficient cooling capacity.
· 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.
· In the heating operation, vapor generated by the defrosting operation looks like white smoke.

and the like.

· Is the NIGHT MODE operation set? Page 9

The room cannot be cooled sufficiently.

· When a ventilation fan or a gas cooker is used in a room, the cooling load increases, resulting in an insufficient cooling effect.
· When the outside temperature is high, the cooling effect may not be sufficient.

The room cannot be heated sufficiently.

· When the outside temperature is low, the heating effect may not be sufficient.

Air does not blow out soon in the heating operation.

· Please wait as the unit is preparing to blow out warm air.

Airflow

The air from the indoor unit smells strange.

· Are the filters clean? Page 12 · Is the fan or heat exchanger of the indoor unit
clean? Page 12 · The unit may suck in an odor adhering to the
wall, carpet, furniture, cloth, etc. and blow it out with the air.

Sound

Cracking sound is heard.

· This sound is generated by the expansion/contraction of the front panel, etc. due to change in temperature.

“Burbling” sound is heard.

· This sound is heard when the outside air is
absorbed from the drain hose by turning on the
range hood or the ventilation fan, making water flowing in the drain hose to spout out. This sound is also heard when the outside air blows into the drain hose in case the outside wind is strong.

Mechanical sound is heard from the indoor unit.
