Safety precautions
•Before starting to use the system, please read these “Safety precautions” carefully to ensure proper operation of the
system.
•When you have read this instruction manual, please keep it without missing. If someone else takes over as operator,
make certain that the manual is also passed on to the new operator.
❚INSTALLATION PRECAUTIONS
❚OPERATION PRECAUTIONS
WARNING
•The system is for domestic, residential etc. use.
If used in severer environments, such as an engineering workplace, the equipment may function poorly.
CAUTION
WARNING
Please observe these precautions with great care, since they are essential to your safety.
•Symbols which appear frequently in the text have the following meaning:
WARNING
CAUTION
Improper handling could lead to drastic result like death, serious injury, etc.
Might pose a serious problem, depending on the circumstances.
Strictly prohibited Provide proper earthing
Observe instructions with
great care
•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.
•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. Incorrect installation of the earth cable may produce an electric shock.
•Do not expose yourself to the cooling air for a
long period.
This could affect your physical condition and
cause health problems.
•Do not insert anything into the air inlet.
This may cause injury, as the internal fan rotates
at high speed.
•Store the remote control out of reach of infants.
Failure to observe this may result in the batteries being swallowed or other accidents.
•Only use approved fuses.
Use of steel or copper wire instead of an approved
fuse is strictly prohibited, as it may cause a break-
down 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.
CAUTION
• The appliance is not intended for use by persons
(including children) with reduced physical,sensory
or mental capabilities, or lack of experience and
knowledge, unless they have been given supervi-
sion or instruction concerning use of the appliance
by a person responsible for their safety.
Children should be supervised to ensure that they
do not play with the appliance.

❚Safety precautions
❚PRECAUTIONS FOR RELOCATION OR REPAIRS
WARNING
CAUTION
•Do not wash the air-conditioner with water.
This could cause an electric shock.
•The system should only be used for its original
purpose and not for anything else like, for in-
stance, 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 di-
rection 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.
•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 supply 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.
•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 supply.
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 im-
proper 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.
•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 profes-
sional 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 supply 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 dizzi-
ness and headache, or deterioration of heart func-
tion 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 gener-
ated.
