Safety precautions

• Before starting to use the system, please read these “Safety precautions” carefully to ensure proper operation of the

system.

• 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.

DANGER

CAUTION

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:

Strictly prohibited Provide proper earthing

Improper handling could lead to drastic result like death, serious injury, etc.
Might pose a serious problem, depending on the circumstances.

Observe instructions with
great care

❚ INSTALLATION PRECAUTIONS

DANGER

• The system is for domestic, residential etc. use.

If used in severer environments, such as an engineering workplace, the equipment may function poorly.

• 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.

CAUTION

• 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.

❚ OPERATION PRECAUTIONS

• Do not expose yourself to the cooling air for a

long period.

This could affect your physical condition and
cause health problems.

• 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 break­down 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.

DANGER

• Do not insert anything into the air inlet.

This may cause injury, as the internal fan rotates
at high speed.

CAUTION

• 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 air­conditioner.

The appliance may then work inadequately.

–2–

❚ Safety precautions

• 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 in­stance, 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.

CAUTION

• 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.

❚ PRECAUTIONS FOR RELOCATION OR REPAIRS

• 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.

Outside temperature

Inside temperature

Inside humidity

Approximately -15 to 46 °C Approximately -15 to 21 °C

Approximately 18 to 32 °C Approximately 15 to 30 °C

Below approximately 80%
The long-term use of the unit with a humidity level
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.

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 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. Placing the filter in sunlight revitalizes the deo­dorizing effect.

Proper installation

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.

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.

Troubleshooting

Please carry out the following checks before making a service call.

The air-conditioner does not work at all.

Has the power switch been
turned off?

Have you set the thermostat
at a suitable temperature?

suitable

tempera-

ture

Is there any direct sunlight
entering the room?

Has the timer been set in the
“ON” position?

Poor cooling or heating

Is the air filter clean? (Not
clogged?)

Poor cooling

Is there a heat source in the
room?

Is there a power failure or a
blown fuse?

Did you leave any doors or
windows open?

Are there too many people
in the room?

If the air-conditioner does not op­erate 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.

An alternative refrigerant (R410A) is used in this air-conditioner. When asking your
dealer for service or inspection and maintenance, explain the dealer about it.

stopped it.

(RUN light is on)

Not

operating?

Airflow is not blown out when starting the HEATING opera­tion.

RUN light blinks slowly

(1.5 sec ON, 0.5 sec OFF)

Airflow is not blown out for 5 to 10 min. or blown out not
warm wind for a moment at HEATING operation.

RUN light blinks slowly

(1.5 sec ON, 0.5 sec OFF)

Airflow is not blown out when starting the DRY operation.

(RUN light is on)

Some steam escapes during COOL operation.

There is a slight smell.

Restart is blocked for 3 minutes after you have stopped the op­eration to protect the unit.

Please wait for
three minutes.

The three-minute protection timer in the microcomputer auto­matically starts it up again.

Airflow has stopped to prevent blowing out of cold air until the
indoor heat exchanger has warmed up. (2 to 5 min.) (HOT
KEEP program)

When outdoor temperature is low and humidity is high, the unit
sometimes performs defrosting automatically. Please wait. Dur­ing defrosting, water or steam may escape from the outdoor
unit.

The indoor fan may stop to prevent re-evaporation of
dehumified moisture and to save energy.

This may occur if the room's temperature and humidity are very
high. It disappears as soon as the temperature and humidity
decrease.

Air blown out during operation may smell. This is caused by
tobacco or cosmetics adhering to the unit.

You hear a slight gurgling sound.

You hear a slight cracking sound.

You hear a hissing or clicking sound.

After a power cut, the unit does not restart even if power
has been restored.

Remote control signals are not received.

Moisture may form on the air outlet grills.

Whistling noise is heard from the outdoor unit.

Fan will not stop immediately after unit operation was
stopped.

RUN light stays on even though operation was stopped.

This is caused by refrigerating liquid moving within the unit.

This is caused by heat expansion or contraction.

This is caused by the operation of the refrigerant control valves
or electric components.

If the auto restart function is not set, the unit will not restart
automatically. Use the remote control to start the operation
again.

Remote control signals may not be received if the signal
receiver on the air-conditioner is exposed to direct sunlight or
other bright light.
If so, cut out the sunlight or reduce the other light.

If the unit is operated for a long time in high humidity, moisture
may form on the air outlet grills and start dripping.

The noise means that the revolution speed of the compressor is
increasing or decreasing.

Indoor fan : Fan will not stop after 2 hours if set to CLEAN

operation.

Outdoor fan : Fan will not stop about a 1 minute period in

order to protect the unit.

The RUN light illuminates during CLEAN operation.
Run light turns off when CLEAN operation ends.

Sometimes a “Shooooo” sound might come for a short time
from the unit that is turned off.

This is the sound when operation of another indoor unit is
stopped.

–19–

Contact your dealer

■ Turn off the power switch immediately and inform your dealer in any of the following situations:

The fuse or switch blows continu­ously.

Fuse often blows.

The TV, radio or other equipment
starts to malfunction.

When abnormalities occur, turn off the power supply
immediately and turn it on after 3 minutes. Restart the
operation with ON/OFF button of the remote control and the
abnormalities still continue.

The cable becomes extremely hot.
The covering of the cable is cracked.

CAUTION

If the power cord becomes damaged, ask your dealer or a qualified engineer to
install the replacement to avoid accidents.

A switch does not activate properly. You hear a strange noise during

operation.

The RUN and TIMER lights on the unit display section blink
quickly (0.5 sec. ON; 0.5 sec. OFF) and do not work.

About the Multiple Air-conditioner

Simultaneous Operation

• The air-conditioners cannot be in different operating modes at the same time, such as one unit being in the “Cool” mode and one
unit being in the “Heat” mode.

• When conducting different operations, the air-conditioner that was operated first will be given priority, so the air-conditioner that is
operated after that will conduct air blowing operation.

• When you want to give priority to the air-conditioner that was started later, either stop the air-conditioner that has priority or cause
the operation type of the unit operated first to match that of the unit operated second.

Automatic Operation

• When the remote control operation switch is in the “Auto” mode the air-conditioner automatically selects either “Cool,” “Dry,” or
“Heat” when operation is started depending on the room temperature.

• During simultaneous operation of air-conditioner units, operation modes may be automatically changed in response to the tem­peratures of the individual rooms; this will result in the operation of the outdoor unit being stopped. In such a case, COOL or HEAT
mode should be used instead of AUTO. (This is only relevant when more than one air-conditioner unit is being used.)

Refrigerant (oil) recovery operation

• If the all of the indoor units are not operated at the same time for an extended period, the cooling or heating performance may
temporarily decrease. This is in order to control the recovery of the refrigerant (oil) in the stopped indoor unit(s). At this time, the
sound of refrigerant flowing may be heard from the stopped indoor unit(s).

d’une méthode de nettoyage inappropriée peut
endommager les composants plastiques de
l’appareil et entraîner des fuites. Tout contact
du détergent avec des composants électriques
ou le moteur de l'appareil peut générer une
panne, de la fumée ou un incendie.

• Arrêtez l’appareil et mettez-le hors tension si

vous entendez le tonnerre ou en cas de risque
de foudre.

Risque d’endommager l’appareil.

PRÉCAUTIONS POUR LE DÉPLACEMENT OU LES RÉPARATIONS DE L’APPAREIL

• Ne réparez ou ne modifiez jamais l'appareil par vous-même. Consultez votre distributeur si

l'appareil a besoin d'être réparé.

Si vous réparez ou modifiez l'appareil, ceci peut causer des fuites d'eau, électrocutions ou incendies.

• Contactez votre revendeur pour toute répara-

tion de l’appareil.

Des réparations inadéquates peuvent provo­quer des décharges électriques, incendies, etc.

• Si le climatiseur doit être déplacé, contactez

votre revendeur ou un installateur profes­sionnel.

Une installation inadéquate peut entraîner des
fuites d’eau, des décharges électriques, des
incendies, etc.

• Si vous remarquez la moindre anomalie

(odeur de brûlé, etc.), arrêtez l’appareil,
mettez-le hors tension et contactez votre
revendeur.

Le fonctionnement continu en cas de condi­tions anormales peut provoquer le dysfonc­tionnement, des décharges électriques, des
incendies, etc.

DANGER

• Le fait que le climatiseur ne refroidisse/ré-

chauffe plus la pièce peut indiquer une fuite
de réfrigérant. Contactez votre revendeur.
S’il faut ajouter du réfrigérant, vérifiez avec
votre revendeur la procédure correcte à sui­vre.

Si le réfrigérant entre en contact avec la peau
nue, il peut provoquer une blessure due au froid.
Si le gaz réfrigérant est inhalé avec excès, il
peut provoquer une détérioration de la fonction
nerveuse se traduisant par des vertiges et des
maux de tête, ou une détérioration de la fonc­tion cardiaque se traduisant par des battements
de cœur irréguliers et des palpitations cardia­ques, d'une durée temporaire. Une fuite acci­dentelle de réfrigérant sur un appareil de chauf­fage, un réchaud, une plaque chauffante ou
toute autre source de chaleur, peut générer des
substances nocives.
