CAUTION

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.

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 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.

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. 

Do not place water containers (flower vases, 

etc.) on the unit, as this may result in electric 
shocks or fire. 

To avoid injury, do not touch the air inlet or 

aluminium fins of the unit.  

Never press the button of the remote controller 

with a hard, pointed object.

The remote controller may be damaged.

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. 

Do not leave the remote controller wherever 

there is a risk of wetting.

If water gets into the remote controller there is a 

risk of electrical leakage and damage to electronic 
components.

Watch your steps at the time of air filter 

cleaning or inspection. 

High-place work is required, to which utmost 

attention must be paid.

If the scaffold is unstable, you may fall or topple 

down, thus causing injury.

Do not sit or place objects on the outdoor unit.

Falling yourself or falling objects could cause injury.

Ensure that the remote controller is not exposed 
to direct sunlight. 

This will cause discoloration of the LCD display with 
resulting loss of readability.

Do not wipe the controller panel with benzene or 
other organic solvent.

This will cause discoloration and/or peeling. If the panel 
needs cleaning, use a damp cloth with some 
water-diluted neutral detergent. Wipe with a dry cloth 
afterwards.

Do not pull or twist the remote controller cord.

This may cause malfunctioning.

Do not operate with the control panel lid open.

If water gets inside the panel,it may result in
equipment failure or electric shock.

Do not place flammable sprays near the unit as 
this can cause explosions.

Arrange the drain hose to ensure smooth 
drainage. 

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

Do not operate the air conditioner when using a 
room fumigation type insecticide.

Fumigation chemicals deposited in the unit could
endanger the health of those who are hypersensitive 
to such chemicals.

Turn off the main power switch when the air condi-
tioner is not to be used for prolonged periods.

When the main power switch is left on, some electric 
power (watts) is still consumed even if the air condi-
tioner is not operating. Therefore, switch off the main 
power switch to save energy. When resuming 
operation, to ensure smooth running, turn on the 
main power switch 6 hours before operating the air 
conditioner again.

Take care of scaffolding and exercise caution 
when working high above ground level.

Arrange the drain hose to ensure smooth drainage.

Imperfect drainage may cause wetting.
