Safety precautions
•Before starting to use the system, please read these “Safety precautions” carefully to ensure proper operation of the system.
•The safety precautions are classified as “ DANGER” and “ CAUTION”. Precautions as shown in the column “ DANGER” indicate
that improper handling could lead to drastic result like death, serious injury, etc. Even precautions as shown in the column “ CAUTION”
might pose a serious problem, depending on the circumstances. 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:
•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.
Strictly prohibited Provide proper earthing
Observe instructions with
great care
❚INSTALLATION PRECAUTIONS
Make sure that the system has been
properly earthed.
Depending on the place of installa-
tion, an earth leakage breaker may
be necessary.
Do not install it where flammable gas
may leak.
Make sure to install the drain hose
properly so that all the water is
drained out.
The system is for domestic, residential
etc. use.
The system must be installed by your
dealer or a qualified professional.
If used in severer environments,
such as an engineering workplace,
the equipment may function poorly.
It is not advisable to install the sys-
tem by yourself, as faulty handling
may cause leakage of water, electric
shock or fire.
Gas leaks may cause fire. If you do not install an earth leak-
age breaker, you may get an elec-
tric shock.
Improper installation may lead to
water drop in the room resulting
in wet furniture.
Earth cables should never be
connected to a gas pipe, water
pipe, lightning conductor or tel-
ephone earth cable. Incorrect in-
stallation of the earth cable may
produce an electric shock.
CAUTIONDANGER
❚OPERATION PRECAUTIONS
Do not expose yourself to the cooling
air for a long period.
Do not insert anything into the air inlet.
DANGER
The appliance is not intended for use by
persons (including children) with reduced
physical,sensory or mental capabilities,
or lack of experience and knowledge, un-
less they have been given supervision or
instruction concerning use of the appli-
ance by a person responsible for their
safety.
Store the remote control out of reach of
infants.
This could affect your physical
condition and cause health prob-
lems.
Do not place a flammable insecticide
or paint spray near the blower, nor
spray it directly on the system.
Do not handle the switches with wet
hands.
Only use approved fuses.
Do not swing from the indoor unit.
This may cause injury, as the in-
ternal fan rotates at high speed.
Use of steel or copper wire in-
stead of an approved fuse is
strictly prohibited, as it may
cause a breakdown or fire.
This may cause an electric
shock.
If the indoor unit falls down,
you may get injured.
This may result in a fire.
CAUTION
Do not wash the air-conditioner with
water.
You should not expose any combus-
tion appliance directly to the air
stream of the air-conditioner.
Children should be supervised to
ensure that they do not play with
the appliance.
The appliance may then work
inadequately.
This could cause an electric
shock.
Do not place anything containing wa-
ter, like vases, on top of the unit.
The system should only be used for its origi-
nal purpose and not for anything else like,
for instance, preservation of food, plants or
animals, precision devices or works of art.
Failure to observe this may re-
sult in the batteries being swal-
lowed or other accidents.
The system is only intended
for use in ordinary domestic
rooms. Any other use of the
system may damage the qual-
ity of food, etc.
Water entering the unit could
damage the insulation and there-
fore cause an electric shock.

❚Safety precautions
CAUTION
❚PRECAUTIONS FOR RELOCATION OR REPAIRS
DANGER
Do not operate the system without
the air filter.
When you clean the system, stop the
unit and turn off the power supply.
Do not install the system where the air-
flow direction is aimed directly at
plants or animals.
Do not sit on the outdoor unit nor put
anything on it.
After a long period of use, check the
unit's support structure from time to
time.
Do not place household electrical ap-
pliances or household items under
neath the indoor or outdoor units.
Stand firmly on a stepladder or other
stable object when removing the inlet
panel and filters.
Do not touch the aluminum fins on the
air heat exchanger.
Do not place objects near the out-
door unit or allow leaves to gather
around the unit.
Contact your dealer to clean inside the
indoor unit, do not attempt to do by
yourself.
This will damage their health. If the unit falls down or things
drop off it, people could get hurt.
If you do not repair any damage
right away, the unit may fall
down and cause personal injury.
It may result in injury. Condensation falling from the
unit may stain objects and cause
accidents or electrical shock.
It can cause malfunction of the
system due to clogging of the
heat exchanger.
Failure to observe this may result
in injury through insecure objects
toppling over.
Never open the panel while the
internal fan is rotating.
If there are objects or leaves
around the outdoor unit, small
animals may enter unit and con-
tact electrical parts and may
cause a break-down, smoke or
fire.
The use of a non-approved deter-
gent or improper washing method
may damage the unit’s plastic com-
ponents and cause leaks. Damage,
smoke, or fire may also happen if
the detergent comes in contact with
electrical parts or the unit’s motor.
Consult your dealer for repairs.
If you notice anything abnormal (smell of
burning, etc.), stop the system, turn off
the power supply and consult your
dealer.
In case the air-conditioner is relo-
cated elsewhere, contact your dealer
or a professional fitter.
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 instruc-
tions.
Wrong repairs could cause an
electric shock, fire, etc.
Faulty installation may cause wa-
ter leakage, electric shock, fire,
etc.
Continued use of the system in ab-
normal circumstances may result
in malfunctioning, electric shock,
fire, etc.
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.
If you operate the system together
with a combustion appliance, you
must regularly ventilate the indoor air.
Do not control the system with main
power switch.
It can cause fire or water leakage.
In addition, the fan can start un-
expectedly, which can cause per-
sonal injury.
Insufficient ventilation may
cause accidents due to oxygen
deficiency.
Do not shut off the power supply imme-
diately after stopping the operation.
Wait at least 5 minutes, otherwise
there is a risk of water leakage or
breakdown.
Do not perform any repairs or modifica-
tions 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.
Stop the unit and turn off the power
if you hear thunder or there is a
danger of lightning.
It may damage the unit.
