Using the air conditioner in such places may cause a fire or
air conditioner failures.

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 normally 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.

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 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.

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.

Consult your local dealer about installation work.

Doing the work yourself may result in water leakage, elec­tric shocks or a fire.

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 earth the air conditioner.

Do not earth the air conditioner 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.

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

The use of any other power supply may cause heat gener­ation, a fire, or air conditioner failures.

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.

The appliance shall be stored so as to prevent mechan­ical damage and in a well-ventilated room without con­tinuously operating ignition sources (example: open
flames, an operating gas appliance or an operating
electric heater) and have a room size as specified in
installation manual (only for R32 refrigerant).

Children should be watched so that they do not play
with the indoor unit or its remote controller.

Accidental operation by a child may result in injury or elec­tric shocks.

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 indoor unit, as
adverse effects may ensue.

Do not place flammable sprays or operate spray con­tainers near the air conditioner as this may result in a
fire.

Do not wash the air conditioner or the remote control­ler with water, as this may result in electric shocks or
fire.

Do not place water containers (flower vases, etc.) on
the indoor unit, as this may result in electric shocks or
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.

Turn off the power when the air conditioner is not used
for long periods of time (only for R410A refrigerant).

Otherwise, the air conditioner may get hot or catch on a fire
due to dust accumulation.

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 a fire when making contact with electrical
parts.

To avoid electric shocks, do not operate with wet
hands.

Never touch the internal parts of the remote controller.

Touching certain internal parts will cause electric shocks
and damage to the remote controller. Consult your local
dealer about checking and adjustment of internal parts.

To avoid oxygen deficiency, ensure that the room is

CAUTION

WARNING

adequately ventilated if equipment such as a burner is
used together with the air conditioner.

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.

Do not remove the outdoor unit’s outlet side grille.

The grille protects against the unit’s high speed fan, which
may cause injury.

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.

To avoid injury, do not touch the air inlet or aluminum
fins of the air conditioner.

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 block air inlets nor outlets.

Impaired airflow may result in insufficient performance or
trouble.

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 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 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.

Do not turn off the breaker unless you smell something
burning, or when doing repairs, inspection or cleaning
of the unit.

Refrigerant leakage cannot be detected otherwise. (Only
for R32 refrigerant)

Do not install in sealed, highly airtight spaces such as
soundproof chambers and room which was sealed up
the door (only for R32 refrigerant).

Do not use flammable substances (such as hairsprays
or insecticides etc.) near the unit.

It could cause electric shock, fire, or a misdetection of the
refrigerant sensor (only for R32 refrigerant).

Do not install in places filled with smoke, gas, chemi­cals etc.

There is a possibility that the sensors inside the indoor unit
could detect these, and display a refrigerant leak abnormal­ity (only for R32 refrigerant).

This unit is equipped with electrically powered safety
measures. To be effective, the unit must be electrically
powered at all times after installation, other than short
service intervals (only for R32 refrigerant).

Before cleaning, be sure to stop the operation, turn the
breaker off or pull out the power supply cord.

After cleaning, quickly turn the power supply breaker
back on.
