Strictly prohibited Provide proper earthing
Observe instructions with
great care
❚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
support structure from time to time.
Do not touch the aluminum fins on the
air heat exchanger.
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 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.
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 sys-
tem due to clogging of the heat ex-
changer.
Wait at least 5 minutes, otherwise
there is a risk of water leakage or
breakdown.
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,

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.

DANGER
•Do not expose directory to airflow from the air-conditioner for a long time.
CAUTION
•When in COOL or DRY operation, do not operate for a long period with the
airflow blowing straight down. Otherwise, condensation may appear on the outlet
grill and drip down.
•Do not try to adjust the flaps and louvers by hand, as the control angle may
change or the flap or louver may not be closed completely.

Installing, inspecting, and replacing the air-cleaning filter
1. Open the air inlet panel and remove the air filters. Page 17
2. Remove the filter holders, with the air-cleaning filter installed in the folders, from the air-
conditioner.
3. Remove the allergen clear filter (Light orange) from filter holder and inspect the filter. Use
a vacuum cleaner to remove any dust or dirt from the allergen clear filter. Replace the
allergen clear filter if it cannot be cleaned or if it has been for about 1 year.
(The allergen clear filter should be replaced after about 1 year of use. However, the actual
replacement period may vary depending on the conditions in which the filter is used.)
Remove the photocatalytic washable deodorizing filter (orange) from the filter holder and
inspect the filter. Periodically, remove any dust or dirt from the photocatalytic washable
deodorizing filter. If the photocatalytic washable deodorizing filter is particularly dirt, it
may be washed with water. However, the filter is fragile so be sure to wash it installed in the
filter holder to avoid damaging it. After washing the filter, place it in sunlight to dry. Plac-
ing the filter in sunlight revitalizes the deodorizing effect.
(Do not dispose of the filter holders. They are reusable. )
4. Install the air-cleaning filter in the filter holders, and then install the filter
holders in the air-conditioner.
5. Install the air filters and closed the air inlet panel. Page 17

Proper installation
Pay attention to operating noises!
•When you install the unit, take care to choose a place that can comfortably stand the weight of the unit and does not increase the operating noise
or vibration. If vibration is transmitted through the house, fix the unit with the aid of vibration-proof pads between the unit and the fittings.
•Select a place where cold or hot air, operation noises from the indoor and outdoor units do not cause any inconvenience to your neighbours.
•Do not leave any obstacles near the outlet and inlet of the outdoor unit. This may cause malfunctioning and increased operating noise.
•If you hear an irregular noise during operation, contact your dealer.
Inspection and maintenance
Depending on operating environment, the inside of the air-conditioner may become dirty after a few year operations. This will reduce
performance. In addition to normal cleaning, we would recommend inspection and maintenance. (This may lead the air-conditioner to having a
longer life without any trouble.)
•Contact your dealer, or any distributor, for inspection and maintenance. (There will be a charge for this service).
•We would recommend inspection and maintenance to be carried out during the off-season.
•If the supply cord of this appliance is damaged, it must only be replaced by a repair shop appointed by the manufacturer, because special
purpose tools are required.
Suitable installation position
•Do not put any obstruction in front of the indoor unit, preventing proper ventilation and functioning.
•Do not install the unit in any of the following places:
•Where there is a danger of leaking flammable gases.
•Where there is substantial splashing of oil.
•Malfunctioning due to corrosion may occur if the unit is installed in a spa where sulfide gases are generated, or in a seaside resort exposed to
sea breezes. Contact your dealer.
•The air-conditioner and remote control must be at least 1 metre away from a TV set or radio.
•Drain the dehumidified liquid from the indoor unit into a spot that drains well.
The air-conditioner does not work at all.
