Description of “AUTO RESTART FUNCTION” RESET CLOCK

• 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 was in the emergency operation before the shutoff of the main power, it will start operation, when main power comes on, in the same mode as the one set with the remote controller before the emergency operation.

• If the unit is operated in “I FEEL...” 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.

Description of “I FEEL...” mode

Details of operation

According to the room temperature when the operation starts, the operation mode is automatically set to COOL, DRY or

HEAT. However, when operation is started again within 2 hours after it is stopped, the same operation mode before the operation is stopped is selected. The operation mode selected first is not changed even if the room temperature changes.

• If the air conditioner absorbs too much heat from the air, it may be overloaded. Following a judgement made by the microprocessor, the fan in the outdoor unit is automatically stopped to protect the air conditioner.

When the outdoor unit’s fan is stopped, frost may form on the outdoor unit, but this is not a problem.

In DRY operation

• The temperature control (temperature setting) cannot be done.

• The room temperature is slightly lowered in this operation mode.

■

The details of the display on the indoor unit are explained on page 6.

NOTE:

When the ambient temperature is too high, the room temperature may not reach the set temperature since the unit operates to cool the room under a high load.

Information for multi system air conditioner (Outdoor unit: MXZ series)

Multi system air conditioner (Outdoor unit: MXZ series) 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 on page 6.)

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 9)

• 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 9)

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 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 stops during the

DRY operation.

• In DRY operation, the unit operates using the same refrigerant circuit as in COOL operation.

DRY operation time has to be reduced in order to lower humidity without much room temperature decreasing. So the compressor sometimes stops, and at the same time the indoor fan stops.

This prevents water condensed on the heat exchanger from evaporating again.

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.

Question Answer (not a malfunction)

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.

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, 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.

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.

INSTALLATION, RELOCATION AND INSPECTION

Installation place

Avoid installing the air conditioner in the following places.

• Where flammable gas could leak.

To prevent the effects of a fluorescent lamp, keep as far apart as possible.

Inverter-type fluorescent lamp

The installation location of the outdoor unit should be at least 3 m away from the antennas for TV sets, radios, etc. In areas where the reception is weak, provide greater space between the outdoor unit and the antenna of the affected device if operation of the air conditioner interferes with radio or TV reception.

wall, etc.

CAUTION:

Do not install the unit where flammable gas could leak.

If gas leaks and collects around the unit, it may cause an explosion.

• Where there is much machine oil.

Keep a space to prevent the picture distortion or the noise.

Wellventilated dry place

• Salty places such as the seaside.

• Where sulfide gas is generated such as a hot spring.

• Where oil is splashed or where the area is filled with oily smoke.

1 m or more

Cordless phone or

Portable phone Radio

1 m or more

TV

100 mm or more

500 mm or more

• Where there is high-frequency or wireless equipment.

• Where the unit will be buried in snow.

• Inside the mobile vehicles such as a crane truck, ship, etc.

• Drain the water from the unit to the soil which has good drainage.

3 m or more

• Cooling and heating capacity may get lowered 10% in the places where poor ventilation and shortcycle of air exchange is likely to occur.

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.

SPECIFICATIONS

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. This may cause water leakage from the unit.

• 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.

• Choose the place which endures the unit weight enought and does not amplify the unit vibration.

• Choose the place in which the operation sound and air blow from the unit don’t bother the house next door.

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.

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