•  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.

•  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.

•  Be sure the air conditioner is electrically 

earthed.

In order to avoid electric shock, make sure that 
the unit is grounded and that the earth wire is 
not connected to gas or water pipe, lightning 
conductor or telephone earth wire.

•  Do not place a flower vase or anything 

containing water on the unit. Water may enter 

the unit, causing an electric shock or fire.

•  Avoid placing the controller in a spot which 

can be splashed with water. Water entering 

the machine may cause an electric leak or 

may damage the internal electronic parts.

•  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.

 CAUTION

•  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.

•  Do not place flammable sprays near the unit 

as this can cause explosions.

•  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 burners or heaters in places 

exposed to the air flow from the unit as this 

may impair combustion of the burner or 

heater.

•  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 or outlets.

Impaired air flow may result in insufficient 
performance or trouble.

•  Arrange the drain hose to ensure smooth 

drainage.

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

•  Arrange the drain hose to ensure smooth 

drainage.

Imperfect drainage may cause wetting.

•  Be sure that children, plants or animals are 

not exposed directly to airflow from the unit, 

as adverse effects may ensue.

•  Do not wash air conditioner or user 

interface, causing an electric shock or fire.

•  Do not put flammable containers, such as 

spray cans, within 1 m from the blow-off 

mouth.

The containers may explode because the warm 
air output of the outdoor unit will affect them.

•  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 user 

interface.

Accidental operation by a child may result in 
impairment of bodily functions and harm health.

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

aluminium fins of the unit.

These fins are sharp and could result in cutting 
injuries.
