WHEN YOU THINK THAT TROUBLE HAS OCCURRED

Indoor Unit
The unit cannot be operated.| •  Is the breaker turned on?

•  Is the power supply plug connected?

•  Is the ON timer set? Page 7

The horizontal vane does not move.| •  Are the horizontal vane and the vertical vane installed correctly?

•  Is the fan guard deformed?

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 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.
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 blow- ing 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 tem- perature 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 control- ler just before the shutoff of the main power. Refer to “Auto restart function”. Page 7

In COOL/DRY mode, when the room temperature reaches near the set temperature, the outdoor unit stops, then the indoor unit operates at low speed.| •  When the room temperature deviates from the set temperature, the indoor fan starts running according to the settings on the remote control- ler.
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 operat- ing.
When heating operation is selected, operation does not start right away.| • When operation is started during defrosting of 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 com- pressor 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

defrosting operation looks like white smoke.

Remote controller
The display on the remote controller does not appear or it is dim. The indoor unit does not respond to the remote control signal.| •  Are the batteries exhausted? Page 4

•  Is the polarity (+, -) of the batteries correct?

Page 4

•  Are any buttons on the remote controller of other electric appliances being pressed?

Does not cool or heat
The room cannot be cooled or heated sufficiently.| •  Is the temperature setting appropriate?

Page 5

•  Is the fan setting appropriate? Please change fan speed to High or Super High. Page 6

•  Are the filters clean? Page 8

•  Is the fan or heat exchanger of the indoor unit clean? Page 8

•  Are there any obstacles blocking the air inlet or outlet of the indoor or outdoor unit?

•  Is a window or door open?

•  It may take a certain time to reach the setting temperature or may not reach that depending on the size of the room, the ambient temperature, and the like.

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 8

•  Is the fan or heat exchanger of the indoor unit clean? Page 8

•  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/con- traction 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.| •  This is the switching sound in turning on/off the fan or the compressor.
The sound of water flowing is heard.| •   This is the sound of refrigerant or condensed

water flowing in the unit.

Hissing sound is sometimes

heard.

| •  This is the sound when the flow of refrigerant inside the unit is changed.

In the following cases, stop using the air conditioner and consult your dealer.

• When water leaks or drips from the indoor unit.
• When the operation indicator lamp blinks.
• When the breaker trips frequently.
• The remote control signal is not received in a room where an electronic ON/ OFF type fl uorescent lamp (inverter-type fl uorescent lamp, etc.) is used.
• Operation of the air conditioner interferes with radio or TV reception. An ampli-fi er may be required for the affected device.
• When an abnormal sound is heard.
• When any refrigerant leakage is found.

WHEN THE AIR CONDITIONER IS NOT GOING TO BE USED FOR A LONG TIME

1. Operate by COOL mode with the highest temperatureset or FAN mode for 3 to 4 hours. Page 5
2. This dries the inside of the unit.
3. Moisture in the air conditioner contributes to favorable conditions for growth of fungi, such as mold.
4. Press to stop the operation.
5. Turn off the breaker and/or disconnect the power supply plug.
6. Remove all batteries from the remote controller.
