SAFETY PRECAUTIONS

Thisapplianceisnotintendedforusebypersons(includingchildren) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Children should be supervised to ensure that they do not play with the appliance.

Do not insert your fi nger, a stick, or other objects into the air inlet or outlet.

•This may cause injury, since the fan inside rotates at high speeds during operation.

In case of an abnormal condition (such as a burning smell), stop the air conditioner and disconnect the power plug or turn the breaker OFF.

•A continued operation in the abnormal state may cause a malfunction,

fi re, or electric shock. In this case, consult your dealer.

When the air conditioner does not cool or heat, there is a possibility of refrigerant leakage. If any refrigerant leakage is found, stop operations and ventilate the room well and consult your dealer immediately. If a repair involves recharging the unit with refrigerant, ask the service technician for details.

•The refrigerant used in the air conditioner is not harmful. Normally, it does not leak. However, if refrigerant leaks and comes in contact with fi re or heating part of such a fan heater, kerosene heater, or cooking stove, it will create harmful gas and there is risk of fi re.

The user should never attempt to wash the inside of the indoor unit. Should the inside of the unit require cleaning, contact your dealer.

•Unsuitable detergent may cause damage to plastic material inside the unit, which may result in water leakage. Should detergent come in contact with electrical parts or the motor, it will result in a malfunction, smoke, or fi re.

•The appliance shall be stored in a room without continuously operating ignitionsources(forexample:openfl ames,anoperatinggasappliance or an operating electric heater).

•Be aware that refrigerants may not contain an odour.

•Do not use means to accelerate the defrosting process or to clean the appliance, other than those recommended by the manufacturer.

•Do not pierce or burn.

This appliance is intended to be used by expert or trained users in shops, in light industry and on farms, or for commercial use by lay persons.

CAUTION

Do not touch the air inlet or the aluminum fi ns of the indoor/outdoor unit.

•This may cause injury.

Do not use insecticides or fl ammable sprays on the unit.

•This may cause a fi re or deformation of the unit.

Do not expose pets or houseplants to direct airfl ow.

•This may cause injury to the pets or plants.

Do not place other electric appliances or furniture under the indoor/ outdoor unit.

•Water may drip down from the unit, which may cause damage or malfunction.

Do not leave the unit on a damaged installation stand.

•The unit may fall and cause injury.

Do not step on an unstable bench to operate or clean the unit.

•This may cause injury if you fall down.

Do not pull the power cord.

•This may cause a portion of the core wire to break, which may cause overheating or fi re.

Do not charge or disassemble the batteries, and do not throw them into a fi re.

•This may cause the batteries to leak, or cause a fi re or explosion.

Do not operate the unit for more than 4 hours at high humidity (80% RH or more) and/or with windows or outside door left open.

•This may cause the water condensation in the air conditioner, which may drip down, wetting or damaging the furniture.

•The water condensation in the air conditioner may contribute to growth of fungi, such as mold.

Do not use the unit for special purposes, such as storing food, raising animals, growing plants, or preserving precision devices or art objects.

•This may cause deterioration of quality, or harm to animals and plants.

Do not expose combustion appliances to direct airfl ow.

•This may cause incomplete combustion.

Never put batteries in your mouth for any reason to avoid accidental ingestion.

•Battery ingestion may cause choking and/or poisoning.

Before cleaning the unit, switch it OFF and disconnect the power plug or turn the breaker OFF.

•This may cause injury, since the fan inside rotates at high speeds during operation.

When the unit will be unused for a long time, disconnect the power plug or turn the breaker OFF.

•The unit may accumulate dirt, which may cause overheating or fi re.

Replace all batteries of the remote controller with new ones of the same type.

•Using an old battery together with a new one may cause overheating, leakage, or explosion.

If the battery fl uid comes in contact with your skin or clothes, wash them thoroughly with clean water.

•Ifthebatteryfl uidcomesincontactwithyoureyes,washthemthoroughly with clean water and immediately seek medical attention.

Ensure that the area is well-ventilated when the unit is operated together with a combustion appliance.

•Inadequate ventilation may cause oxygen starvation.

Turn the breaker OFF when you hear thunder and there is a possibility of a lightning strike.

•The unit may be damaged if lightning strikes.

After the air conditioner is used for several seasons, perform inspection and maintenance in addition to normal cleaning.

•Dirt or dust in the unit may create an unpleasant odor, contribute to growth of fungi, such as mold, or clog the drain passage, and cause water to leak from the indoor unit. Consult your dealer for inspection and maintenance, which require specialized knowledge and skills.

Do not operate switches with wet hands.

•This may cause electric shock.

Do not clean the air conditioner with water or place an object that contains water, such as a fl ower vase, on it.

•This may cause fi re or electric shock.

Do not step on or place any object on the outdoor unit.

• This may cause injury if you or the object falls down.

IMPORTANT

Dirty fi lters cause condensation in the air conditioner which will contribute to the growth of fungi such as mold. It is therefore recommended to clean air fi lters every

2 weeks.

Before starting the operation, ensure that the horizontal vanes are in the closed position. If operation starts when the horizontal vanes are in the open position, they may not return to the correct position.

How to set remote controller exclusively for a particular indoor unit

A maximum of 4 indoor units with wireless remote controllers can be used in a room.

To operate the indoor units individually with each remote controller, assign a number to each remote controller according to the number of the indoor unit.

This setting can be set only when all the following conditions are met:

• The remote controller is powered OFF.

(1)Hold down button on the remote controller for 2 seconds to enter the pairing mode.

(2)Press button again and assign a number to each remote controller.

Each press of button advances the number in the following order: 1 → 2 → 3 → 4.

(3)Press button to complete the pairing setting.

After you turn the breaker ON, the remote controller that fi rst sends a signal to an indoor unit will be regarded as the remote controller for the indoor unit. Once they are set, the indoor unit will only receive the signal from the assigned remote controller afterwards.
