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
•
The system is for domestic, residential etc. use.
If used in severer environments, such as an engineering workplace, the equipment
may function poorly.
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, se-
rious injury, etc.
Might pose a serious problem, depending on the circum-
stances.
Strictly prohibited Provide proper earth-
ing
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 leak-
age 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 installa-
tion, 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 furni-
ture.
• 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 elec-
tric shock.
CAUTION

❚OPERATION PRECAUTIONS
WARNING
CAUTION
• Cleaning and user maintenance shall
not be made by children without su-
pervision.
• Do not insert anything into the air in-
let.
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 persons
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.
• 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 combus-
tion appliance directly to the air
stream of the air-conditioner.
The appliance may then work inad-
equately.
• Do not wash the air-conditioner with
water.
This could cause an electric shock.
• Children shall not play with the appli-
ance.
• Do not expose yourself to the cooling
air for a long period.
This could affect your physical condition
and cause health problems.
❚Safety precautions
• The system should only be used for
its original purpose and not for any-
thing else like, for instance, preserva-
tion of food, plants or animals, preci-
sion 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 wa-
ter, 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 supply im-
mediately after stopping the opera-
tion.
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 acci-
dents 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 out-
door 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 con-
tact 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 let the foreign matters enter
the indoor unit through the air out-
lets.
This may cause the dumper inoperable.
• If the power cord becomes damaged,
contact your dealer or a qualified en-
gineer.
If it is not replaced, it may cause a
breakdown or fire.

❚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 relo-
cated 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 supply
and consult your dealer.
Continued use of the system in abnor-
mal circumstances may result in mal-
functioning, electric shock, fire, etc.
• If the air-conditioner fails to cool or
warm the room, it may have a refrig-
erant 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 exces-
sively, it may cause deterioration of nerve
function like dizziness and headache, or
deterioration of heart function like irregu-
lar heartbeat and heart palpitation tempo-
rarily. If refrigerant unexpectedly leaks
from the unit onto a fan heater, stove,
hotplate or other heat source, harmful
gases could be generated.

battery is used, liquid may leak from the battery, causing the remote control to
malfunction.
•The recommended effective period is printed on the battery. This may be
shorter due to manufacturering time to the unit. However, the battery may
still be in working order after expiry of its nominal life.
