•Symbols which appear frequently in the text have the following meaning:
DANGER
CAUTION
Improper handling could lead to drastic result like death, serious injury, etc.
Might pose a serious problem, depending on the circumstances.
Strictly prohibited Provide proper earthing
Observe instructions with
great care
•The system must be installed by your dealer or a qualified professional.
It is not advisable to install the system by yourself, as faulty handling may cause leakage of water, electric
shock or fire.
•Do not install it where flammable gas may leak.
Gas leaks may cause fire.
•Depending on the place of installation, an
earth leakage breaker may be necessary.
If you do not install an earth leakage breaker,
you may get an electric shock.
•Make sure to install the drain hose properly
so that all the water is drained out.
Improper installation may lead to water drop in
the room resulting in wet furniture.
•Make sure that the system has been properly earthed.
Earth cables should never be connected to a gas pipe, water pipe, lightning conductor or telephone earth
cable. Incorrect installation of the earth cable may produce an electric shock.
•Do not expose yourself to the cooling air for a
long period.
This could affect your physical condition and
cause health problems.
•Do not insert anything into the air inlet.
This may cause injury, as the internal fan rotates
at high speed.
•Store the remote control out of reach of infants.
Failure to observe this may result in the batteries being swallowed or other accidents.
•Only use approved fuses.
Use of steel or copper wire instead of an approved
fuse is strictly prohibited, as it may cause a break-
down or fire.
•Do not handle the switches with wet hands.
This may cause an electric shock.
•Do not swing from the indoor unit.
If the indoor unit falls down,you may get injured.
•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.
•You should not expose any combustion
appliance directly to the air stream of the air-
conditioner.
The appliance may then work inadequately.

❚Safety precautions
❚PRECAUTIONS FOR RELOCATION OR REPAIRS
DANGER
CAUTION
•Do not wash the air-conditioner with water.
This could cause an electric shock.
•The system should only be used for its original
purpose and not for anything else like, for in-
stance, preservation of food, plants or animals,
precision devices or works of art.
The system is only intended for use in ordinary
domestic rooms. Any other use of the system
may damage the quality of food, etc.
•Do not place anything containing water, like
vases, on top of the unit.
Water entering the unit could damage the
insulation and therefore cause an electric shock.
•Do not install the system where the airflow di-
rection is aimed directly at plants or animals.
This will damage their health.
•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.
•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 touch the aluminum fins on the air heat
exchanger.
It may result in injury.
•Do not place household electrical appliances
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 operate the system without the air
filter.
It can cause malfunction of the system due to
clogging of the heat exchanger.
•Do not shut off the power supply immediately
after stopping the operation.
Wait at least 5 minutes, otherwise there is a risk of
water leakage or breakdown.
•Do not control the system with main power
switch.
It can cause fire or water leakage. In addition,
the fan can start unexpectedly, which can cause
personal injury.
•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.
•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 toppling over.
•When you clean the system, stop the unit
and turn off the power supply.
Never open the panel while the internal fan is
rotating.
•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
electrical parts and may cause a break-down,
smoke or fire.
•Contact your dealer to clean inside the
indoor unit, do not attempt to do by yourself.
The use of a non-approved detergent or im-
proper washing method may damage the unit’s
plastic components and cause leaks. Damage,
smoke, or fire may also happen if the detergent
comes in contact with electrical parts or the
unit’s motor.
•Stop the unit and turn off the power if you
hear thunder or there is a danger of lightning.
It may damage the unit.
•Do not perform any repairs or modifications by yourself. Consult the dealer if the unit requires

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.

Installing, inspecting, and replacing the air-cleaning filter
1. Open the air inlet panel and remove the air filters. Page 16
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 photo-
catalytic washable deodorizing filter. If the photocatalytic washable deodorizing fil-
ter 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. Placing the filter in sunlight revitalizes the deo-
dorizing 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 16
NOTE
•The allergen clear filter and the photocatalytic washable deodorizing filter
may be installed on either the right or left side of the air-conditioner.
•Install the allergen clear filter with the light orange side front.
At the end of the season
CAUTION
•The heat exchanger may injure your fingers.
Item Feature Color
For replacement the air-cleaning filter, contact your dealer.

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.
Has the timer been set in the
“ON” position?
Has the power switch been
turned off? Is there a power failure or a blown fuse?
Troubleshooting

Poor cooling
Poor cooling or heating
Did you leave any doors or
windows open?
Have you set the thermostat
at a suitable temperature?
Is there a heat source in the
room? Are there too many people in the room?
Is the air filter clean? (Not
clogged?)
suitable
tempera-
ture
Is there any direct sunlight
entering the room?
If the air-conditioner does not op-
erate properly after you have
checked the left points, or if any
doubt still exists after you have
consulted page 19, or if things
happen as shown on page 20,
switch off the power and contact
your dealer.
