❚INSTALLATION PRECAUTIONS
❚OPERATION PRECAUTIONS
DANGER
Make sure that the system has been
properly earthed.
Depending on the place of installation,
an earth leakage breaker may be neces-
sary.
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 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 con-
ductor or telephone earth cable. Incor-
rect installation 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 prohib-
ited, as it may cause a breakdown or
fire.
This may cause an electric shock. If the indoor unit falls down,
you may get injured.
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
CAUTIONDANGER
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.
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.

❚Safety precautions
CAUTION
❚PRECAUTIONS FOR RELOCATION OR REPAIRS
DANGER
Do not shut off the power supply im-
mediately after stopping the opera-
tion.
Do not place objects near the outdoor
unit or allow leaves to gather around
the unit.
Do not sit on the outdoor unit nor put
anything on it.
After a long period of use, check the unit's

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 21 °C 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.
