HEN YOU THINK THAT TROUBLE HAS OCCURRED

Even if these items are checked, when the unit does not recover from the trouble, stop using the air conditioner and consult your dealer.

Symptom Explanation & Check points

Indoor Unit

The unit cannot be operated.

• Is the breaker turned on?

• Is the power supply plug connected?

• Is the ON timer set?

• Is there anything that block the normal operation of the damper? Page 5

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

HORIZONTAL VANE is suspended for a while, then restarted.

The air fl ow direction changes during operation.

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

The operation is stopped for about 10 minutes in the heating operation.

The unit starts operation by itself when the main power is turned on, though it isn’t operated with the remote controller.

The damper opens and closes automatically.

• This is for the swing operation of the HORI-

ZONTAL VANE to be performed normally.

• In the heating operation, if the air fl ow temperature is too low or when defrosting is being done, the horizontal vane is automatically set to vertical position.

• When the air conditioner is operated in

COOL or DRY mode, if the operation continues with air blowing down for 1 hour, the direction of the air fl ow is automatically set to position (1) to prevent condensed water from dropping.

• The horizontal vane automatically moves in certain intervals to determine its position, and then it returns to the set position.

• Defrosting of the outdoor unit is being done.

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.)

• 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 4

.

• The damper is automatically controlled by a microcomputer according to the air fl ow temperature and operation time of the air conditioner.

Multi system

The indoor unit which is not operating becomes warm and a sound, similar to water fl owing, is heard from the unit.

When heating operation is selected, operation does not start right away.

• A small amount of refrigerant continues to fl ow 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.

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.

Water leaks from the outdoor unit.

• When the outside temperature is low during cooling operation, the fan operates intermittently to maintain suffi cient 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 water frozen on the outdoor unit melt and drip down.

Symptom

White smoke is discharged from the outdoor unit.

Explanation & Check points

• 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 3

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

Page 3

• 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 suffi ciently.

The room cannot be cooled suffi ciently.

The room cannot be heated suffi ciently.

Air does not blow out soon in the heating operation.

Airfl ow

The air from the indoor unit smells strange.

• Is the temperature setting appropriate?

Page 4

•

Is the fan setting appropriate? Please change fan speed to higher setting. Page 5

•

Is the air outlet selection switch set to upper air outlet only? Change to upper and lower air outlets. Page 5

•

Is the fi lter clean? Page 7

•

Is the fan or heat exchanger of the indoor unit clean? Page 7

•

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

•

Is a window or door open?

•

When a ventilation fan or a gas cooker is used in a room, the cooling load increases, resulting in an insuffi cient cooling effect.

• When the outside temperature is high, the cooling effect may not be suffi cient.

•

When the outside temperature is low, the heating effect may not be suffi cient.

•

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

•

•

Is the fi lter clean? Page 7

Is the fan or heat exchanger of the indoor unit clean? Page 7

•

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.

The sound as burbling is heard.

Mechanical sound is heard from the indoor unit.

The sound of water fl owing is heard.

Hissing sound is sometimes heard.

• This sound is generated by the expansion/ contraction of the intake grille, etc. due to change in temperature.

• 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 fl owing 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.

• This is the switching sound in turning on/off the fan or the compressor.

• This is the sound of refrigerant or condensed water fl owing in the unit.

• This is the sound when the fl ow of refrigerant inside the unit is switched.

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

• When water leaks or drips from the indoor unit.

• When the upper 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 amplifi er may be required for the affected device.

• When an abnormal sound is heard.
