Do not longer use the air conditioner until a qual-
ified service 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 mea-
sures so that the amount of any leaked refriger-
ant 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 manu-
facturer.

If a defect results from your own workmanship, it 
may result in water leaks, electric shock or fire.

Consult your local dealer regarding reloca-
tion 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 
reading.

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 condi-
tioner.

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 sub-
merges owing to a natural disaster, such as a 
flood or typhoon.

Do not operate the air conditioner in that case, or 
otherwise a malfunction, electric shock, or fire 
may result.

Do not start or stop operating the air condi-
tioner with the power supply breaker turned 
ON or OFF.

Otherwise, fire or water leakage may result. Fur-
thermore, the fan will rotate abruptly if power fail-
ure compensation is enabled, which may result 
in inlury.

Do not use the product in the atmosphere con-
taminated 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 exces-
sive 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 product 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 generation, fire, or product failures.

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 preci-
sion instruments, food, plants, animals or works 
of art as this may adversely affect the perfor-
mance, quality and/or longevity 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 out-
door 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 containers near the unit as this may 
result in fire.
Before cleaning, be sure to stop unit opera-
tion, 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 place the controller exposed to direct 
sunlight.

The LCD display may get discolored, failing to 
display the data.
