Safety Precautions 

•  Keep this manual where the user 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

Failure to follow these instructions properly may result in 

personal injury or loss of life. 

,&CAUTION

Failure to follow these instructions properly may result in 

property damage or personal injury, which may be serious 

depending on the circumstances. 

(9 

Never attempt. 

Be sure to follow the instructions. 

•  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 

• To avoid fire, explosion or injury, do not operate the unit 

when harmful gases (e.g. flammable or corrosive) are 

detected near the unit. 

•  Be aware that prolonged, direct exposure to cool air from the air conditioner, 

or to air that is too cool, 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 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 shock or fire hazards. 

•  Do not use flammable spray near the air conditioner, or otherwise 

fire may result. 

•  Do not use a refrigerant other than the one indicated on the outdoor 

unit (R32) when installing, moving or repairing. Using other refrigerants 

may  cause trouble or damage to the unit, and personal injury. 

•  To avoid electric shock, do not operate with wet hands. 

• Beware of fire in case of refrigerant leakage. If the air conditioner is 

not operating correctly, i.e. not generating cool air, refrigerant leakage 

could be the cause. Consult your service centre 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 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 

shock or fire hazards. Please contact your local service centre or 

qualified personnel for installation and maintenance work. 

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

etc.), turn off power to the unit and contact your local service 

centre. Continued operation under such circumstances may 

result in a failure, electric shock or fire hazards. 

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

the earth leakage circuit breaker may result in electric shock or fire. 

•  Be sure to earth the unit. Do not earth the unit to a utility 

A

pipe, lightning conductor or telephone earth lead. 

V

Imperfect earthing may result in electric shock. 

,&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 the 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 the air inlets  or 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. 

•  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 . 

•  After prolonged use, check the unit stand and its mounts for damage. If 

they are left in a damaged condition, the unit may fall and cause injury. 

•  To avoid injury, do not touch the air inlet or aluminium fins of the 

indoor or outdoor units. 

• 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. 

• 

Avoid impacts to the indoor and outdoor units, or otherwise 

product damage may result. 

•  Do not place flammable items, such as spray  cans, within 1 m of 

the air outlet. The spray cans may explode as a result of hot air 

from the indoor or outdoor units. 

• 

Be careful not to let pets urinate on the air conditioner. Urination 

on the air conditioner may result in electric shock or fire. 

•  Do not wash the air conditioner with water, as this may result in 

electric shock or fire. 

•  Do not place water containers (vases,  etc.) above the unit, as this 

may result in electric shock or fire hazards if they should topple over. 

•  Do not insert the batteries  in the wrong po/-) orientation 

as this may result In short circuiting, fire, or battery leakage. 

•  To avoid oxygen depletion, ensure that the room is 

adequately ventilated if equipment such as a burner is 

used together with the air conditioner. 

•  Before cleaning, be sure to stop unit operation and turn off 

the circuit breaker. Otherwise, an electric shock and injury may result. 

•  Only  connect the air conditioner to the specified power supply 

circuit. Power supplies other than the one specified may result in 

electric shock, overheating and fires. 

•  Arrange the drain hose to ensure smooth drainage. Imperfect 

drainage may cause wetting of the building, furniture, etc. 

•  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 inside the unit,  such animals can cause malfunctions, 

smoke or fire if they come into contact with electrical parts. 

•  Do not place objects around the indoor unit. 

Doing so may have an adverse influence on the performance, 

product quality, and life of the air conditioner. 

• This appliance is not intended to be used by persons with reduced 

physical, sensory or mental capabilities, or with lack of operation 

knowledge, unless they have been given supervision or instruction 

concerning the appliance use by person responsible for their safety. 

Keep out of children's reach to ensure that they do not play with the appliance.
