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 odour, etc.) turn off power to the unit
and contact your local dealer.
Continued operation under such circumstances may
result in a failure, electric shocks or fire hazards.
Consult your local dealer about installation work.
Doing the work yourself may result in water leakage, electric shocks or fire hazards.
Consult your local dealer regarding modification,
repair and maintenance of the air conditioner.
Improper workmanship may result in water leakage, electric shocks or fire hazards.
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
highspeed fan blades.
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.

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 normally does not
leak. However, in the event of a leakage, contact with a
naked burner, heater or cooker may result in generation of
noxious gas. Do not longer use the air conditioner until a
qualified service person confirms that the leakage has
been repaired.
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.
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 otherwise
a malfunction, electric shoch, 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. Furthermore,
the fan will rotate abruptly if power failure compensation is
enabled, which may result in inlury.
Do not use the product in the atmosphere contaminated 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 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 precision instruments, food, plants, animals or works of art as this may
adversely affect the performance, 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.
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 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 indoor or outdoor unit will affect them.
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 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.
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 let children play on or around the outdoor unit.
If they touch the unit carelessly, injury may be caused.
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.
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 hose to ensure smooth drainage.
Imperfect drainage may cause wetting.
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.
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.
To avoid injury, do not touch the air inlet or aluminium fins of the unit.
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.
Do not block air inlets nor outlets.
Impaired air flow may result in insufficient performance or
trouble.
