❚Safety precautions
❚INSTALLATION PRECAUTIONS
WARNING
• The system is for domestic and residential use.
If used in severe environments, such as an engineering workplace, the equipment may
function poorly.
• The system must be installed by your dealer or a qualified professional.
It is not advisable to install the system by yourself, as faulty handling may cause
leakage of water, electric shock or fire.
CAUTION
• Do not install it where flammable gas may leak.
Gas leaks may cause fire.
• Depending on the place of installation,
an earth leakage breaker may be
necessary.
If you do not install an earth leakage
breaker, you may get an electric shock.
• Make sure to install the drain hose
properly so that all the water is drained
out.
Improper installation may lead to water
drop in the room resulting in wet furniture.
• Make sure that the system has been properly earthed.
Earth cables should never be connected to a gas pipe, water pipe, lightning conductor
or telephone earth cable. Improper installation of the earth cable may produce an
electric shock.

❚Safety precautions
❚OPERATION PRECAUTIONS
WARNING
• Children shall not play with the
appliance.
• Do not expose yourself to the cooling
air for a long period.
This could affect your physical condition
and cause health problems.
• Cleaning and user maintenance shall
not be made by children without
supervision.
• Do not insert anything into the air
outlet.
This may cause injury, as the internal fan
rotates at high speed.
• This appliance can be used by children aged from 8 years and above and people
with reduced physical, sensory or mental capabilities or lack of experience and
knowledge, if they have been given supervision or instruction concerning use of
the appliance in a safe way and understand the hazards involved.
• Store the remote control out of reach of infants.
Failure to observe this may result in the batteries being swallowed or other accidents.
CAUTION
• Only use approved fuses.
Use of steel or copper wire instead of an
approved fuse is strictly prohibited, as it
may cause a breakdown or fire.
• Do not handle the switches with wet
hands.
This may cause an electric shock.
• Do not swing from the indoor unit.
If the indoor unit falls down,you may get
injured.
• Do not place a flammable insecticide
or paint spray near the blower, nor
spray it directly on the system.
This may result in a fire.
• You should not expose any
combustion appliance directly to the
air stream of the air-conditioner.
The appliance may then work
inadequately.
• Do not wash the air-conditioner with
water.
This could cause an electric shock.
Using a high pressure washer may cause
damage to the aluminum fins, resulting in
performance decrement.
• Do not use for preservation of food,
plants or animals, precision devices or
works of art.
The system is only intended for use in
ordinary domestic rooms. Any other use
of the system may damage the quality of
food, etc.
• Do not place anything containing
water, like vases, on top of the unit.
Water entering the unit could damage the
insulation and therefore cause an electric
shock.
• Do not install the system where the
airflow direction is aimed directly at
plants or animals.
This will damage their health.
• Do not sit on the outdoor unit nor put
anything on it.
If the unit falls down or things drop off it,
people could get hurt.
• After a long period of use, check the
unit’s support structure from time to
time.
If you do not repair any damage right
away, the unit may fall down and cause
personal injury.

❚Safety precautions
CAUTION
• Do not touch the aluminum fins on the
air heat exchanger.
It may result in injury.
• Do not place household electrical
appliances or household items under
neath the indoor or outdoor units.
Condensation falling from the unit may
stain objects and cause accidents or
electrical shock.
• Do not operate the system without the
air filter.
It can cause malfunction of the system
due to clogging of the heat exchanger.
• Do not shut off the power source
immediately after stopping the
operation.
Wait at least 5 minutes, otherwise there is
a risk of water leakage or breakdown.
• Do not control the system with main
power switch.
It can cause fire or water leakage. In
addition, the fan can start unexpectedly,
which can cause personal injury.
• Do not pour liquid into this unit and do
not put water container on this unit.
Water entering the unit could damage the
insulation and therefore cause an electric
shock.
• If you operate the system together with
a combustion appliance, you must
regularly ventilate the indoor air.
Insufficient ventilation may cause
accidents due to oxygen deficiency.
• Stand firmly on a stepladder or other
stable object when removing the inlet
panel and filters.
Failure to observe this may result in injury
through insecure objects toppling over.
• When you clean the system, stop the
unit and turn off the power source.
Never open the panel while the internal
fan is rotating.
• Do not place objects near the outdoor
unit or allow leaves to gather around
the unit.
If there are objects or leaves around the
outdoor unit, small animals may enter
unit and contact electrical parts and may
cause a break-down, smoke or fire.
• Contact your dealer to clean inside the
indoor unit, do not attempt to do by
yourself.
The use of a non-approved detergent or
improper washing method may damage
the unit’s plastic components and cause
leaks. Damage, smoke, or fire may also
happen if the detergent comes in contact
with electrical parts or the unit’s motor.
• Stop the unit and turn off the power if
you hear thunder or there is a danger
of lightning.
It may damage the unit.
• If the power cord becomes damaged,
contact your dealer or a qualified
engineer.
If it is not replaced, it may cause a
breakdown or fire.

❚Safety precautions
❚PRECAUTIONS FOR RELOCATION OR REPAIRS
WARNING
• Do not perform any repairs or modifications by yourself. Consult the dealer if the
unit requires repair.
If you repair or modify the unit, it can cause water leaks, electric shocks or fire.
• Consult your dealer for repairs.
Wrong repairs could cause an electric
shock, fire, etc.
• In case the air-conditioner is relocated
elsewhere, contact your dealer or a
professional fitter.
Faulty installation may cause water
leakage, electric shock, fire, etc.
• If you notice anything abnormal (smell
of burning, etc.), stop the system, turn
off the power source and consult your
dealer.
Continued use of the system in
abnormal circumstances may result in
malfunctioning, electric shock, fire, etc.
• If the air-conditioner fails to cool
or warm the room, it may have a
refrigerant leakage. Contact your
dealer.
If refrigerant needs to be added,
check with your dealer for proper
instructions.
If the refrigerant comes in contact with the
bare skin, it may cause cold injury.
If the refrigerant gas is inhaled
excessively, it may cause deterioration
of nerve function like dizziness and
headache, or deterioration of heart
function like irregular heartbeat and heart
palpitation temporarily. If refrigerant
unexpectedly leaks from the unit onto
a fan heater, stove, hotplate or other
heat source, harmful gases could be
generated.
