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
DANGER
❚OPERATION PRECAUTIONS
DANGER
Make sure that the system has been properly earthed.
Depending on the place of installation, 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 pro-
fessional.
If used in severer environments, such as an engineering
workplace, the equipment may function poorly.
It is not advisable to install the system 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 leakage breaker, you may get an
electric 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 telephone earth cable. Incorrect installa-
tion of the earth cable may produce an electric shock.
Do not expose yourself to the cooling
air for a long period.
Store the remote control out of reach
of infants.
Do not swing from the indoor unit.
This could affect your physical condi-
tion and cause health problems.
This may cause injury, as the inter-
nal fan rotates at high speed.
Failure to observe this may result in
the batteries being swallowed or
other accidents.
Use of steel or copper wire instead of
an approved fuse is strictly
prohibited, as it may cause a break-
down or fire.
This may cause an electric shock. If the indoor unit falls down,
you may get injured.
CAUTION
Do not wash the air-conditioner with wa-
ter.
You should not expose any combus-
tion appliance directly to the air
stream of the air-conditioner.
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. The appliance may then work inad-
equately.
This could cause an electric shock.
Do not insert anything into the air inlet.
Do not handle the switches with wet
hands.
Only use approved fuses.
CAUTION

Safety precautions
CAUTION
❚PRECAUTIONS FOR RELOCATION OR REPAIRS
DANGER
Stand firmly on a stepladder or other
stable object when removing the inlet
panel and filters.
Do not place objects near the outdoor
unit or allow leaves to gather around
the unit.
Do not place anything containing wa-
ter, like vases, on top of the unit.
The system should only be used for its original purpose
and not for anything else like, for instance, preservation of
food, plants or animals, precision devices or works of art.
Do not install the system where the
airflow 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 touch the aluminum fins on the
air heat exchanger.
If you operate the system together
with a combustion appliance, you
must regularly ventilate the indoor air.
When you clean the system, stop the
unit and turn off the power supply.
Do not place household electrical appli-
ances or household items under neath
the indoor or outdoor units.
Contact your dealer to clean inside
the indoor unit, do not attempt to do
by yourself.
Stop the unit and turn off the power if
you hear thunder or there is a danger of
lightning.
The system is only intended for use in
ordinary domestic rooms. Any other
use of the system may damage the
quality of food, etc.
Water entering the unit could dam-
age the insulation and therefore
cause an electric shock.
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.
Insufficient ventilation may cause
accidents due to oxygen deficiency.
Failure to observe this may result in
injury through insecure objects top-
pling 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 contact electri-
cal parts and may cause a break-
down, smoke or fire.
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.
It may damage the unit.
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
relocated 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 instructions.
Wrong repairs could cause an electric
shock, fire, etc.
Faulty installation may cause water
leakage, electric shock, fire, etc.
Continued use of the system in ab-
normal circumstances may result in
malfunctioning, electric shock, fire,
etc.
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.

Air-conditioner operable temperature setting
■Use within the following operational range. Operating outside of this range may result in the protection devices being activated, preventing the
unit from working.
Cooling operation Heating operation
Outside temperature Approximately -15 to 46 °C Approximately -15 to 21 °C
Inside temperature Approximately 18 to 32 °C Approximately 15 to 30 °C
Below approximately 80%
The long-term use of the unit with a humidity level
Inside humidity exceeding 80% may result in condensation forming on the —
surface of the indoor unit, leading to water drips.
Characteristics of HEAT mode operation
Mechanism and capacity of HEAT mode operation
■Mechanism
•The unit draws heat from the cold outside air, transfers it to indoors and heats the room. As a characteristic of heat pump system, the heating capacity
reduces when the outside air temperature gets colder.
•It may take some time to supply hot air after turning on the air-conditioner.
•If the outside temperature becomes extremely low, it would be better to use an additional source of heating.
Defrosting
If the outside temperature becomes low and humidity is high, the heat exchanger in the outdoor unit may frost over, which prevents efficient heating.
If this happens, the automatic defrost function is activated and during defrosting the heating operation stops for 5 to 15 minutes
during defrosting.
•Both indoor and outdoor fans stop and the RUN light blinks slowly (1.5 sec. ON, 0.5 sec. OFF) during defrosting.
•The outdoor unit may give off some steam during defrosting. This is to help the defrosting process and is not a defect.
•The HEAT operation resumes as soon as defrosting has been completed.
Press the FAN SPEED button
Set the fan speed as preferred.
