The precautions described herein are classified as WARNING and CAUTION. They both contain important information regarding safety. Be sure to observe all precautions without fail.

[!] WARNING: Failure to follow these instructions properly may result in personal injury or loss of life.

[!] CAUTION: Failure to observe these instructions properly may result in property damage or personal injury, which may be serious depending on the circumstances.

After reading, keep this manual in a convenient place so that you can refer to it whenever necessary. If the equipment is transferred to a new user, be sure also to hand over the manual.

WARNING

Be aware that prolonged, direct exposure to cool or warm air from the air conditioner, or to air that is too cool or too warm can be harmful to your physical condition and health.

When the air conditioner is malfunctioning (giving off a burning odor, etc.) turn off power to the unit and contact your local dealer. Continued operation under such circumstances may result in a failure, electric shocks or fire hazards.

Consult your local dealer to install your equipment. Doing the work yourself may result in water leakage, electric shocks or fire hazards.

Consult your local dealer regarding modification, repair and maintenance of the air conditioner or the remote controller. Improper workmanship may result in water leakage, electric shocks or fire hazards.

Do not place objects, including rods, your fingers, etc., in the air inlet or outlet. Injury may result due to contact with the air conditioner's high-speed fan blades.

Beware of fire in case of refrigerant leakage. If the air conditioner is not operating correctly, i.e. not generating cool or warm air, refrigerant leakage could be the cause. Consult your dealer for assistance. The refrigerant within the air conditioner is safe and normally does not leak. However, in the event of a leakage, contact with a naked burner, heater or cooker may result in generation of noxious gas. Do not longer use the air conditioner until a qualified service person confirms that the leakage has been repaired.

Consult your local dealer regarding what to do in case of refrigerant leakage. When the air conditioner is to be installed in a small room, it is necessary to take proper measures so that the amount of any leaked refrigerant does not exceed the concentration limit in the event of a leakage. Otherwise, this may lead to an accident due to oxygen depletion.

Contact professional personnel about attachment of accessories and be sure to use only accessories specified by the manufacturer. If a defect results from your own workmanship, it may result in water leaks, electric shock or fire.

Consult your local dealer regarding relocation and reinstallation of the air conditioner. Improper installation work may result in leakage, electric shocks or fire hazards.

Be sure to use fuses with the correct ampere reading. Do not use improper fuses, copper or other wires as a substitute, as this may result in electric shock, fire, injury or damage to the unit.

Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in electric shocks or fire.

Be sure to earth the unit. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks or fire.

A high surge current from lightning or other sources may cause damage to the air conditioner.

Consult the dealer if the air conditioner submerges owing to a natural disaster, such as a flood or typhoon. Do not operate the air conditioner in that case, or otherwise a malfunction, electric shock, or fire may result.

Do not start or stop operating the air conditioner with the power supply breaker turned ON or OFF. Otherwise, fire or water leakage may result. Furthermore, the fan will rotate abruptly if power failure compensation is enabled, which may result in injury.

Do not use the product in the atmosphere contaminated with oil vapor, such as cooking oil or machine oil vapor. Oil vapor may cause crack damage, electric shocks, or fire.

Do not use the product in places with excessive oily smoke, such as cooking rooms, or in places with flammable gas, corrosive gas, or metal dust. Using the product in such places may cause fire or product failures.

Do not use flammable materials (e.g., hairspray or insecticide) near the product.

Do not clean the product with organic solvents such as paint thinner. The use of organic solvents may cause crack damage to the product, electric shocks, or fire.

Be sure to use a dedicated power supply for the air conditioner. The use of any other power supply may cause heat generation, fire, or product failures.

CAUTION

Do not use the air conditioner for purposes other than those for which it is intended. Do not use the air conditioner for cooling precision instruments, food, plants, animals or works of art as this may adversely affect the performance, quality and/or longevity of the object concerned.

Do not remove the outdoor unit's fan guard. The guard protects against the unit's high speed fan, which may cause injury.

Do not place objects that are susceptible to moisture directly beneath the indoor or outdoor units. Under certain conditions, condensation on the main unit or refrigerant pipes, air filter dirt or drain blockage may cause dripping, resulting in fouling or failure of the object concerned.

1 OPERATION MODE SELECTOR

Press OPERATION MODE SELECTOR button several times and select the OPERATION MODE of your choice as follows.

• COOLING OPERATION: The recommended set temperature is 26 to 28°C.
• HEATING OPERATION: The recommended set temperature is 18 to 23°C.
• AUTOMATIC OPERATION: In this operation mode, COOL/HEAT changeover is automatically conducted. AUTOMATIC OPERATION controls the temperature based on the set temperature, so it maintains a comfortable temperature throughout the year.

<Example> When the indoor temperature decreases to 23°C or less when the set temperature is at 25°C in the AUTOMATIC COOLING OPERATION, the operation is changed over to the AUTOMATIC HEATING OPERATION. When the indoor temperature reaches 27°C or more, the operation is changed over to the AUTOMATIC COOLING OPERATION.

FAN OPERATION

Air in the room is circulated.

PROGRAM DRY OPERATION

• The function of this program is to decrease the humidity in your room with the minimum temperature decrease.

NOTE: Do not turn OFF power immediately after the unit stops. Then, wait no less than 5 minutes. Water is leaking or there is something else wrong with the unit.

CHARACTERISTICS OF THE COOLING OPERATION (COOLING OPERATION AND AUTOMATIC COOLING OPERATION)

• After continuous operation with the airflow horizontally or downward, the air conditioner operates with different airflow direction for a certain period of time to prevent condensation build-up on the airflow direction blades. (The remote controller displays the airflow direction that is set.)
• If the COOLING OPERATION is used when the indoor temperature is low, frost adheres to the heat exchanger of the indoor unit. This can decrease the cooling capacity. In this case, the system automatically switches to DEFROST OPERATION for a while.

During DEFROST OPERATION, the low fan speed is used to prevent the discharge of melt water. (The remote controller displays the fan speed that is set.)

• When the outside temperature is high, it takes some time until the indoor temperature reaches the set temperature.

CHARACTERISTICS OF THE HEATING OPERATION (HEATING OPERATION AND AUTOMATIC HEATING OPERATION)

START OF OPERATION

• It generally takes a longer time for indoor temperature of the HEATING OPERATION to reach the set temperature compared to the COOLING OPERATION. It is advisable to start operation in advance using the TIMER OPERATION.

After operation is stopped

• The fan operates for about 1 minute to dispel heat inside the indoor unit.

Perform the following operation to prevent heating capacity decrease and discharge of cool air.

AT THE START OF OPERATION AND AFTER DEFROST OPERATION

• A warm air circulating system is employed, and therefore it takes some time until the entire room is warmed up after the start of operation.
• The indoor fan runs to discharge a gentle wind automatically until the temperature inside the air conditioner reaches a certain level. At this time, the DEFROST OPERATION LAMP on the light receiving unit indicator lights. Leave it as it stands and wait for a while. (The remote controller displays the fan speed that is set.)
• The air discharge direction becomes horizontal to prevent a draft of cool air to the inhabitants. (The remote controller will display the set airflow direction.)

DEFROST OPERATION (Frost removal operation for the outdoor unit)

• As the frost on the coil of an outdoor unit increase, heating effect decreases and the system goes into the DEFROST OPERATION.
• The warm air stops, and the DEFROST OPERATION LAMP on the light receiving unit turn on. (The remote controller displays the fan speed that is set.)
• After maximum 10 minutes of the DEFROST OPERATION, the air conditioner returns to the HEATING OPERATION.
• The airflow direction becomes horizontal. (The remote controller displays the airflow direction that is set.)
• During or after the DEFROST OPERATION, white mist comes out from the air inlet or outlet of the air conditioner.
• A hissing and “Shuh” sound may be heard during this particular operation.

Regarding outside air temperature and heating capacity

• The heating capacity of the air conditioner declines as the outside air temperature falls. In such a case, use the air conditioner in combination with other heating systems. (When a combustion appliance is used, ventilate the room regularly.) Do not use the combustion appliance where the air from the air conditioner is blown directly toward it.

• When the warm air stays under the ceiling and your feet are cold, we recommend that you use a circulator (a fan to circulate the air inside the room). For details, consult your local dealer.
• When the indoor temperature exceeds the set temperature, the indoor unit discharges a gentle breeze (switches to gentle wind). The airflow direction becomes horizontal. (The remote controller displays the fan speed and airflow direction that are set.)

FAN OPERATION

• Only the fan inside the indoor unit operates, and the air in the room is circulated.

CHARACTERISTICS OF THE PROGRAM DRY OPERATION

• This operation lowers the humidity without lowering the indoor temperature. The indoor temperature when the operation button is pressed will be the set temperature. At this time, the fan speed and temperature are set automatically, so the remote controller does not display the fan speed and set temperature.
• To efficiently lower the indoor temperature and humidity, first use the COOLING OPERATION to lower the indoor temperature, and then use the PROGRAM DRY OPERATION. When the indoor temperature is lowered, airflow from the indoor unit may stop.
• When operating continuously at downward airflow direction, air blows in the automatically set direction for a period of time to prevent condensation on the horizontal blades.
• If the PROGRAM DRY OPERATION is used when the indoor temperature is low, frost forms on the heat exchanger of the indoor unit. In this case, the system automatically switches to the DEFROST OPERATION for a while.

ADJUSTMENT

For programming TEMPERATURE, FAN SPEED and AIRFLOW DIRECTION, follow the procedure shown below.

TEMPERATURE SETTING

Press TEMPERATURE SETTING button and program the set temperature.

Each time this button is pressed, set temperature rises 1°C.

Each time this button is pressed, set temperature lowers 1°C.
