Description of “AUTO RESTART FUNCTION”

• These units are equipped with an auto restart function. When the main power is turned on, the air conditioner will start operation automatically in the same mode as the one set with the remote controller before the shutoff of the main power.

• If the unit was set to off with the remote controller before the shutoff of the main power, it will remain stopped even after the main power is turned on.

• If the unit is operated in “ AUTO” mode before power failure, the operation mode (COOL, DRY or HEAT) is not stored in the memory. When the main power is turned on, the unit decides the operation mode by the initial room temperature at restart and starts operation again.

Information for multi system air conditioner

Multi system air conditioner can connect two or more indoor units with one outdoor unit. According to the capacity, two or more units can operate simultaneously.

• When you try to operate two or more indoor units with one outdoor unit simultaneously, one for the cooling and the other for heating, the operation mode of the indoor unit that operates earlier is selected. The other indoor units that will start the operation later cannot operate, indicating an operation state. (Refer to the table of Operation Indicator lamp below.)

In this case, please set all the indoor units to the same operation mode.

• When indoor unit starts the operation while the defrosting of outdoor unit is being done, it takes a few minutes (max.

10 minutes) to blow out the warm air.

• In the heating operation, the indoor unit that does not operate may get warm or the sound of refrigerant flowing may be heard. This is not a malfunction since the refrigerant continuously flows into the indoor unit that does not operate.

BEFORE CONTACTING THE SERVICE REPRE-

SENTATIVE, CHECK THE FOLLOWING AGAIN

Question Check points or Remedy

The air conditioner cannot be operated.

• Is the breaker turned on?

• Is the fuse blown?

• Is the ON timer set? (Page 8)

The room cannot be cooled or heated sufficiently.

• Is the temperature setting correct? (Page 7)

• Is the filter clean? (Page 10)

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

• Is a window or door open?

The air from the indoor unit smells strange.

• Is the filter clean? (Page 10)

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 5)

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

(Page 5)

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

When a power failure occurs.

• Does the air conditioner start operating again?

If the air conditioner had operated before the power failure, as these models are equipped with an auto restart function, the air conditioner should start operating again. (Refer to Description of “AUTO RESTART FUNCTION” on page

6.)

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

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

• When water leaks or drops from the indoor unit.

• When the left operation indicator lamp blinks.

• When the breaker trips frequently.

• The remote control signal may not be received in a room where an electronic

ON/OFF type fluorescent lamp (inverter-type fluorescent lamp, etc.) is used.

• Operation of the air conditioner may interfere with radio or TV reception in areas where the reception is weak. An amplifier may be required for the affected device.

• When thunder is heard, stop operation and disconnect the power supply plug or turn off the breaker. Otherwise, the electrical parts may be damaged.

WHEN YOU THINK THAT TROUBLE HAS OCCURRED

Question Answer (not a malfunction)

The air conditioner cannot be operated for about 3 minutes when restarted.

• This protects the air conditioner according to instructions from the microprocessor. Please wait.

Cracking sound is heard.

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

The air from the indoor unit smells strange.

• The air conditioner may suck in an odor adhering to the wall, carpet, furniture, cloth, etc. and blow it out with the 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.

• When the outside temperature is low, the fan may not operate to maintain sufficient cooling capacity.

The sound of water flowing is heard.

• This is the sound of refrigerant flowing inside the air conditioner.

• This is the sound of condensed water flowing in the heat exchanger.

• This is the sound of the heat exchanger defrosting.

The sound as burbling is heard.

• This sound is heard when the outside air is absorbed from the drain hose in turning on the range hood or the ventilation fan and that makes water flowing in the drain hose sucked up.

This sound is also heard when the outside air blows into the drain hose in case the outside wind is strong.

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 air temperature is high, the cooling effect may not be sufficient.

Mist is discharged from the air outlet of the indoor unit.

• The cool air from the air conditioner rapidly cools moisture in the air inside the room, and it turns into mist.

The air flow direction changes during operation.

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

• 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 flow is automatically set to horizontal to prevent condensed water from dropping.

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

Question

Water leaks from the outdoor unit.

Answer (not a malfunction)

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

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

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

White smoke is discharged from the outdoor unit.

• In the heating operation, vapor generated by the defrosting operation looks like white smoke.

Air does not blow out soon in the heating operation.

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

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

• Defrosting of the outdoor unit is being done (Defrosting operation).

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

Hissing sound is sometimes heard.

• This is the sound when the flow of refrigerant inside the air conditioner is switched.

The room cannot be heated sufficiently.

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

The swing operation of the

VERTICAL VANE is suspended for about 15 seconds, then restarted.

• This is for the swing operation of the VERTICAL

VANE to be performed normally.

In a multi-unit 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.

The air conditioner starts the operation only with the main power turned on, though you do not operate the unit with the remote controller.

• These models are equipped with an auto restart function. When the main power is turned off without stopping the air conditioner with the remote controller and is turned on again, the air conditioner will start operation automatically in the same mode as the one set with the remote controller just before the shutoff of the main power.

* The required space depends on the type of outdoor unit.

WARNING :

If the air conditioner operates but does not cool or heat (depending on model) the room, consult your dealer since there may be a refrigerant leak. Be sure to ask the service representative whether there is refrigerant leakage or not when repairs are carried out.

The refrigerant charged in the air conditioner is safe. Refrigerant normally does not leak, however, if refrigerant gas leaks indoors, and comes into contact with the fire of a fan heater, space heater, stove, etc., harmful substances will be generated.

Electrical work

• Provide an exclusive circuit for the power supply of the air conditioner.

• Be sure to observe the breaker capacity.

WARNING :

• The customer should not install this unit.

If installation is done incorrectly, it may cause a fire, an electric shock, or injury from the unit falling, water leaking, etc.

• Do not use intermediate connection of the power supply cord or the extension cord and do not connect many devices to one AC outlet.

A fire or an electric shock may result from poor contact, poor insulation, exceeding the permissible current, etc.

Consult your dealer.

CAUTION:

• Earth the unit.

Do not connect the earth to a gas pipe, water pipe, lightning rod or the earth of a telephone. If the earthing is incorrect, it may cause an electric shock.

• Install an earth leakage breaker depending on the place where the air conditioner is to be installed (humid places, etc.).

If the earth leakage breaker is not installed, it may cause an electric shock.

Inspection and maintenance

• When the air conditioner is used for several seasons, the capacity may be lowered due to dirt inside the unit.

• Depending on the condition, an odor may be generated or dehumidified water may not drain out smoothly due to dirt, dust, etc.

• It is recommended that the unit be inspected and maintained (charged) by specialist in addition to normal maintenance.

Consult your dealer.

Operating sound considerations

• Do not put an object around the air outlet of the outdoor unit. This may lower the capacity or increase the volume of the operating sound.

• If an abnormal sound is heard during operation, consult your dealer.

Relocation

• When the air conditioner is to be removed or re-installed because of rebuilding, moving, etc., special techniques and work are required.

WARNING :

Repairs or relocation should not be done by the customer.
