MAINTENANCE OF THE UNIT

• Clean the unit by wiping with a piece of soft and dry cloth.

If the unit is very dirty, wipe it with a piece of cloth wet with neutral detergent dissolved in lukewarm water and wipe it off with clean water.

AT THE END OF THE SEASON (after a long period of use)

• Clean the air filter and mount it.

• Clean the indoor/outdoor units.

AT THE BEGINNING OF THE SEASON (after a long unused period)

• Inspect the air filter. If it is dirty, clean and mount it.

• Turn on the power supply button for 6 hours before starting the operation.

TROUBLE SHOOTING

Check the following items before requiring service.

THE UNIT DOES NOT WORK AT ALL

Is the power supply switch turned off?

POOR COOLING OR HEATING POOR COOLING

Is the air filter clogged?

If, after checking the items above, the air conditioner still does not operate normally or in the next cases, stop operating and contact your dealer.

• If the fuse and breaker blow frequently. • If water drips at cooling/dehumidifying operation. • If the operation or operation noise is abnormal.

• If the check indicator light flashes.

The phenomena mentioned below is not malfunction.

The air conditioning system sounds as if water is draining from it.

Sounds of rustling or gurgling may be heard from a stopped indoor unit.

Is there a blackout or is the fuse blown?

Is the leakage breaker activated?

Dangerous. Immediately turn off the power supply switch, and contact your dealer.

Is sunlight or other strong illumination striking the receive unit? (wireless unit)

NO AIRFLOW AT HEATING

Is the swing louver horizontal (during heating)?

If the swing louver is horizontal, the airflow may not reach down to the floor.

Sounds of rustling or gurgling may be heard when the operation is started, when the compressor is activated/ deactivated during operation, or when the operation is stopped. These are the sounds of the refrigerant flowing through the system.

These sounds can be heard when the air conditioning system is performing automatic control.

Are there any obstacles blocking the air inlet and outlet grill?

• Is the direct daylight coming into the room?

• Are there any unexpected heat sources in the room?

• Are there too many people in the room?

Is the unit in the heating preparation mode?

See page 18

TROUBLE SHOOTING

The phenomena mentioned below is not malfunction.

The supply air from the indoor unit smells bad.

White vapor is generated from the indoor unit during operation.

The operation switched to fan operation during cooling operation.

The operation switched to fan operation during cooling operation.(in case of FDFW type)

The indoor fan does not stop even when the operation is stopped in heating mode.

The air conditioning system cannot start operating again immediately after stopping.

No air comes out during dehumidifying operation. The airflow volume cannot be changed.

The swing louver moves without any operation.

The outdoor unit discharges water or steam during heating operation.

The operation mode cannot be selected (in case of the heat recovery system KXR).

The outdoor unit fan is not running even when the system is in operation.

Slapping sounds are heard. These sounds are generated when plastic components are expanded or shrunk by the heat and rubbed with

Hissing sounds are heard when the operation is stopped or during defrost operation.

The air conditioner starts operation automatically as soon as the power supply is turned on.

The setting temperature cannot be changed (the setting temperature display flashes).

The airflow becomes weak if the operation mode is changed during operation (in case of the heat recovery system KXR).

In case of wirless remote control, the unit does not operate with the inspection display light on the indoor unit flashing even though any button on the remote control is pressed.

The supply air from the indoor unit may smell bad if the smell of cigarettes, cosmetics and/or furniture has saturated the air conditioning system.

White vapor may be generated during operation if the system is used in environment where oils and fats are frequently used, such as in restaurants. In this case, consult the dealer and clean the heat exchanger.

The operation may switch to fan operation automatically in order to avald frost being built up on the surface of the heat exchanger. The operation will soon return to cooling operation.

In case the relative humidity is 73% or higher, the operation may alternate between fan operation and cooling operation even though the thermostat has not been activated. The objective of this operation mode is to prevent condensate dew formation and dew dropping from indoor unit air supply port.

The indoor unit fan may continue operating for 40 seconds in order to remove remaining heat in the indoor unit.

REQUESTS

Do not turn off the power supply until the fan stops.

During the first 3 minutes after stopping operation, it is not possible to perform cooling, dehumidifying or heating operation even if the ON/OFF button is pressed to indicate “operation.” This is because a circuit for protecting the compressor is activated (the fan is operating during this period).

During dehumidifying operation, the fan speed is automatically controlled in low speed/stop cycle in order to avoid both drastic temperature drop and humidity rise.

The swing louver automatically swings twice when the power supply switch is turned on. This is not a trouble. The louver also moves automatically to the horizontal position when “PREPARATION OF HEATING” is displayed.

Water or steam is discharge during defrosting operation which removes frost built up on the surface of the heat exchanger in the outdoor unit in heating mode.

When operation mode is set to the main and sub indoor unit during the heat recovery system KXR, operation mode of the sub unit cannot be selected.(In this case, the system conforms to operation mode of the main unit.)

The fan speed is automatically controlled according to the ambient temperature. It may be stopped in high ambient temperature in case of heating, and in low ambient temperature in case of coding. Also, the fan is stopped during defrosting operation.

REQUESTS

The fan will suddenly begin to operate even if it is stopped. Do not insert finger and/or stick.

each other. These sounds are generated when the refrigerant valve inside the air conditioning system is activated.

In case the automatic restart function is enabled, and when the power supply recovers, the system restarts the operation automatically as same condition as before power supply is cut.

If changing the set temperature is prohibited on the remote control, it is not possible to change the temperature setting even T or S is pressed.

When you switch the operation mode from Cool to Heat or from Heat to Cool during operation, the airflow becomes weak for 3 minutes.

In case the system is controlled by the other centralized remote control and it forbids operating the system from the remote control, it is not possible to operate by the remote control.

See below

See right

PREPARATION OF HEATING

CASES WHEN “ (PREPARATION OF HEATING)” IS DISPLAYED

“ (PREPARATION OF HEATING)” is displayed in the remote control display area in the following cases.

For wireless devices, the run/check display lamp on the main body display unit will flash green. Setting temperature and preparation of heating are displayed on the wired remote control.

• At Starting Heating Operation

In order to prevent cool air from blowing out, the airflow into the room may be stopped depending on the room temperature at the start of heating operation. please wait for a while and the operation automatically switches to the normal heating operation.

• At defrost operation (during heating operation)

When frost may easily formed on the outdoor unit, the heating operation automatically is stopped (both indoor/outdoor unit stop fan operation) for approximately 5 to 10 minutes per hour and defrosting is operated. After the defrosting is complete, the operation automatically switches back to the normal operation.

HEATING OPERATION

• Heat pump type

Heat pump type heating is the heating mechanism in which the refrigerant takes in outer temperature to supply heat into the room.

• Defrost operation

During heating with a heat pump type air conditioner, frost will be formed on the outdoor unit if the temperature outside the room drops. If left alone, the heating efficiency decreases. In order to deal with this, the operation is automatically switched to defrost operation to remove the frost. During the period, the airflow of indoor/outdoor unit is stopped and “heating defrost” is displayed.

• Outer air temperature and heating capacity

The heating efficiency of heat pump type air conditioner decreases as the outside temperature becomes lower. If the capacity of air conditioner for heating is not sufficient, please use other heating device.

• Time required until the room temperature increases

A heat type air conditioner circulates warm air to warm the entire room, so it takes a while to rise up the room temperature. It is recommended to start operation earlier on a very cold day.

• When room temperature adjusting device operates during heating

INSTALLATION, RELOCATION, AND INSPECTION MAINTENANCE

Please observe the following points in order to use the air conditioner in a safe and comfortable manner. Make sure to request your dealer for installation, never try to do so by yourself.

INSTALLATION LOCATION

Is the system installed in a well-ventilated place?

Are there any obstacles? If so, it leads to the decrease of the efficiency and the increase of operation noise.

Avoid the place where cool/warm air and operation noise cause problems to your neighbors.

ELECTRICAL WORK

Caution : Make sure to perform grounding work

Do not connect the ground wire to any gas pipe, water pipe, or wires of lightning conductors and telephones. If the ground work is not good, it may lead to electric shock.

Caution : Make sure to mount a leakage breaker

Electrical installation work must be performed by an electrical installation service provider qualified by a power provider of the country. Electrical installation work must be executed according to the technical standards and other regulations applicable to electrical installations in the country.

 Is the wiring designated for the air conditioner?  Is the remote control mounted correctly?

Normally the efficiency of the air conditioning system will become lower after a while, because dirt accumulates inside the system. This occurs gradually in around 3 years of use , depending on the condition of use and surrounding enviroment. It is thus necessary to conduct inspection maintenance in addition to regular maintenance. We recommend you to consult the dealer from whom you purchased the system and make a contract for periodical inspection. (charged).

If it is not mounted there, it may lead to electric shock.

• In the case of exposed wiring, is the wiring fixed with the attached screw?

• Is the attached remote control clamps used for fixing the remote control cord?

• Is the remote control mounted at a height where children cannot reach?

RELOCATION
