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 nor-
mally does not leak. 
However, in the event of a leakage, contact with a naked 
burner, heater or cooker may result in generation of nox-
ious gas. 
Do not longer use the air conditioner until a qualified ser-
vice 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 read-
ing.

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 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.

Be sure to install an earth leakage breaker.

Failure to install an earth leakage breaker may result in 
electric shocks or fire.

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 other-
wise 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. Further-
more, the fan will rotate abruptly if power failure compen-
sation is enabled, which may result in injury.

Do not use the product in the atmosphere contami-
nated 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 prod-
uct 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.

Be sure to use a dedicated power supply for the air 
conditioner.

The use of any other power supply may cause heat gen-
eration, 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. 

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 instru-
ments, food, plants, animals or works of art as this may 
adversely affect the performance, quality and/or longev-
ity 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 con-
tainers 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 with water, as this 
may result in electric shocks or fire.
