WARNING
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.
When the air conditioner is malfunctioning (giving
off a burning odor, etc.), turn off the power to the air
conditioner and contact your local dealer.
Continued operation under such circumstances may
result in a failure, electric shocks or a fire.
Consult your local dealer about installation work.
Doing the work yourself may result in water leakage,
electric shocks or a fire.
Consult your local dealer regarding modification,
repair and maintenance of the air conditioner.
Improper workmanship may result in water leakage,
electric shocks or a fire.
Do not place objects, including rods, your fingers,
etc., in the air inlet or outlet.
Injury may result due to contact with the air conditioner’s
high-speed fan blades.
Beware of a 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 local dealer for assistance. The
refrigerant used for the air conditioner is safe and nor-
mally does not leak. However, if the refrigerant leaks and
gets in contact with a naked burner, heater or cooker,
it may generate hazardous compounds. Turn off the air
conditioner and call your local dealer. Turn on the air
conditioner after the qualified service person makes sure
to confirm that the leakage is repaired.
Consult your local dealer regarding what to do in
case of refrigerant leakage.
When the air conditioner is 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 leakage, electric shocks or a fire.
Consult your local dealer regarding relocation and
reinstallation of the air conditioner.
Improper installation work may result in leakage, electric
shocks or a fire.
Be sure to use fuses with the correct ampere reading.
Do not use improper fuses, copper or other wiring as
a substitute, as this may result in electric shocks, a fire
injury or damage to the air conditioner.
Be sure to earth the air conditioner.
Do not earth the unit to a utility piping, lightning conductor or telephone earth lead.
Imperfect earthing may result in electric shocks or a 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 a fire.
Consult your local 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 malfunction, electric shocks, or a fire may result.
Start or stop the air conditioner with the remote controller. Never use the power circuit breaker for this
purpose.
Otherwise, it may cause a fire or water leakage. Further
more, if an automatic restart control is provided against
power failure and the power is recovered, the fan will
rotate suddenly and may cause injury.
Do not use the air conditioner in the atmosphere
contaminated with oil vapor, such as cooking oil or
machine oil vapor.
Oil vapor may cause crack damage to the air conditioner,
electric shocks, or a fire.
Do not use the air conditioner in places with excessive oily smoke, such as cooking rooms, or in places
with flammable gas, corrosive gas, or metal dust.
Using the air conditioner in such places may cause a fire
or air conditioner failures.

Do not use flammable materials (e.g., hairspray or
insecticide) near the air conditioner.
Do not clean the air conditioner with organic solvents such as paint thinner.
The use of organic solvents may cause crack damage to
the air conditioner, electric shocks, or a 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, a fire, or air conditioner failures.
Consult your local 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 outlet side grille.
The guard protects against the unit’s high-speed fan,
which may cause injury.
To avoid oxygen deficiency, 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 or operate spray containers near the air conditioner as this may result in
a fire.
Do not put flammable containers, such as spray
cans, within 1 m from the air outlet.
The containers may explode because the warm air from
the indoor or outdoor unit will affect them.
Before cleaning, be sure to stop the air conditioner
operation, turn the power circuit breaker off.
Otherwise, an electric shocks and injury may result.
To avoid electric shocks, do not operate with wet
hands.
Do not place objects that are susceptible to moisture
directly beneath the indoor or outdoor units.
Under certain conditions, condensation on the unit or
refrigerant piping, air filter dirt or drain blockage may
cause dripping, resulting in fouling or failure of the object
concerned.
Do not place appliances that produce naked flames
in places exposed to the airflow from the air conditioner as this may impair combustion of the burner.
Do not place heaters directly below the indoor 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.
Be sure that children, plants or animals are not

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 a fire.
Carry out drain piping properly to ensure complete
drainage.
If drain piping is not carried out properly, drain will not
flow out. Then, dirt and debris may be accumulated in the
drain piping and may cause water leakage. If it occurs,
stop the air conditioner and call your local dealer for
assistance.
