Safety Precautions

• Keep this manual where the operator can easily find it.

• Read the precautions in this manual carefully before operating the unit.

• 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

 CAUTION

Failure to follow these instructions properly may result in 

personal injury or loss of life.

Failure to observe these instructions properly may result in 

property damage or personal injury, which may be serious 

depending on the circumstances.

Never attempt.

Never wet the air conditioner nor the remote controller with 

water.

Be sure to follow the instructions.

Never touch the air conditioner nor the remote controller with 

wet hands.

Be sure to establish an earth connection.

• 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

•  In order to avoid fire, explosion or injury, do not operate the unit when harmful, among which flammable or corrosive 

gases, are detected near the unit.

•  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.

•  Do not place objects, including rods, your fingers, etc., in the air inlet or outlet. Product malfunctioning, product or 

injury damage may result due to contact with the air conditioner’s high-speed fan blades.

•  Do not attempt to repair, dismantle, reinstall or modify the air conditioner yourself as this may result in water leakage, 

electric shocks or fire hazards.

•  Do not use flammable spray near the air conditioner, or otherwise fire may result.
•  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.

•  Do not attempt to install or repair the air conditioner yourself. Improper workmanship may result in water leakage, 

electric shocks or fire hazards. Please contact your local dealer or qualified personnel for installation and 

maintenance work.

•  When the air conditioner is malfunctioning (giving off a burning odour, 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.

•  Be sure to install an earth leakage breaker. Failure to install the 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.

   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 expose plants or animals directly to airflow from the unit as this may cause adverse effects.

•  Do not place appliances that produce naked flames in places exposed to the airflow from the unit as this may impair 

combustion of the burner.

•  Do not block air inlets nor outlets. Impaired airflow may result in insufficient performance or trouble.

•  Do not sit on the outdoor unit, put things on the unit, or pull the unit. Doing so may cause accidents, such as falling or 

toppling down, thus resulting in injury, product malfunctioning, or product damage.
