Safety precautions
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.
Do not place household electrical appli-
ances 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 control the system with main
power switch.
It can cause fire or water leakage. In
addition, the fan can start unexpect-
edly, which can cause personal injury.
When you clean the system, stop the
unit and turn off the power supply.
Never open the panel while the
internal fan is rotating.
Stop the unit and turn off the power if
you hear thunder or there is a danger of
lightning.
It may damage the unit.
PRECAUTIONS FOR RELOCATION OR REPAIRS
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.
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 ab-
normal circumstances may result in
malfunctioning, electric shock, fire,
etc.
CAUTION
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 operate the system without the
air filter.
It can cause malfunction of the sys-
tem due to clogging of the heat ex-
changer.
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.
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 electri-
cal parts and may cause a break-
down, smoke or fire.
DANGER
Consult your dealer for repairs.
Wrong repairs could cause an 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.
The refrigerant used in your air-conditioner is safe. However, if refrigerant unexpectedly
leaks from the unit onto a fan heater, stove, hotplate or other heat source, harmful gases could
be generated.
– 3 –
Do not touch the aluminum fins on the
air heat exchanger.
It may result in injury.
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.
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 top-
pling over.
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 compo-
nents and cause leaks. Damage,
smoke, or fire may also happen if the
detergent comes in contact with
electrical parts or the unit's motor.
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.
