General Warnings

• 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.

General Cautions

• 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.
• 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.
• 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.
• Do not place flammable sprays or operate spray containers near the unit as this may result in fire.
• Before cleaning, be sure to stop unit operation, turn the breaker off or remove the power cord. Otherwise, an electric shock and injury may result.
• To avoid electric shocks, do not operate with wet hands.
• Do not place appliances that produce naked flames in places exposed to the air flow from the unit as this may impair combustion of the burner.
• Do not place heaters directly below the unit, as resulting heat can cause deformation.
• Do not allow a child to mount on the outdoor unit or avoid placing any object on it. Falling or tumbling may result in injury.
• Do not block air inlets nor outlets. Impaired air flow may result in insufficient performance or trouble.
• Be sure that children, plants or animals are not exposed directly to airflow from the unit, as adverse effects may ensue.
• Do not wash the air conditioner or the remote controller with water, as this may result in electric shocks or fire.
• Do not place water containers (flower vases, etc.) on the unit, as this may result in electric shocks or fire.
• Do not install the air conditioner at any place where there is a danger of flammable gas leakage. In the event of a gas leakage, build-up of gas near the air conditioner may result in fire hazards.

Explanation of Heating Operation

Defrost Operation

• As the frost on the coil of an outdoor unit increases, heating effect decreases and the system goes into DEFROST OPERATION.
• The fan operation stops and the DEFROST lamp (??) of the indoor unit goes on.
• After 6 to 8 minutes (maximum 10 minutes) of DEFROST OPERATION, the system returns to HEATING OPERATION.

Heating Capacity & Outdoor Air Temperature

• Heating capacity drops as outdoor air temperature lowers. If feeling cold, use another heater at the same time as this air conditioner.
• Hot air is circulated to warm the room. It will take some time from when the air conditioner is first started until the entire room becomes warm. The internal fan automatically turns at low speed until the air conditioner reaches a certain temperature on the inside. In this situation, all you can do is wait.
• If hot air accumulates on the ceiling and feet are left feeling cold, it is recommended to use a circulator. For details, contact the place of purchase.
