PRIOR TO USE This operation manual is exclusively for instructions on how to use the wireless remote controller. Read also the operation manual attached to the indoor unit for safe usage of the system and maintenance.
1. Safety precautions
To gain full advantage of the air conditioner’s functions and to avoid malfunction due to mishandling, we recommend that you read this instruction manual carefully before use. This air conditioner is classified under “appliances not accessible to the general public”.
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 to hand over the manual as well.
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 use the air conditioner any longer until a qualified service person confirms that the leakage has been repaired.

English

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 re-installation 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, 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.
2

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 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.
To avoid oxygen depletion, ensure that the room is adequately ventilated if equipment such as a burner is used together with the air conditioner.
After prolonged use, check the unit stand and its mounts for damage. If left in a damaged condition, the unit may fall and cause injury.
English

Do not place flammable sprays or operate spray containers near the unit as this may result in fire.

The batteries must be removed from the appliance before it is scrapped and they are disposed of safely.

Arrange the drain to ensure complete drainage. If proper drainage from the outdoor drain pipe does not occur during air conditioner operation, there could be a blockage due to dirt and debris build-up in the pipe. This may result in a water leakage from the indoor unit. Under these circumstances, stop air conditioner operation and consult your dealer for assistance.
The appliance is not intended for use by unattended young children or infirm persons. Impairment of bodily functions and harm to health may result.
Children should be supervised to ensure that they do not play with the unit or its remote controller. Accidental operation by a child may result in impairment of bodily functions and harm health.
Do not let children play on or around the outdoor unit. If they touch the unit carelessly, injury may be caused.
Consult your dealer regarding cleaning the inside of the air conditioner. Improper cleaning may cause breakage of plastic parts, water leakage and other damage as well as electric shocks.
To avoid injury, do not touch the air inlet or aluminum fins of the unit.
Do not place objects in direct proximity of the outdoor unit and do not let leaves and other debris accumulate around the unit. Leaves are a hotbed for small animals which can enter the unit. Once in the unit, such animals can cause malfunctions, smoke or fire when making contact with electrical parts.
Never touch the internal parts of the controller. Do not remove the front panel. Touching certain internal parts will cause electric shocks and damage to the unit. Please consult your dealer about checking and adjustment of internal parts.
