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
repair.
If you repair or modify the unit, it can cause water leaks, electric shocks or fire.
• Consult your dealer for repairs.
Wrong repairs could cause an electric shock,
fire, etc.
• In case the air-conditioner is relocated
elsewhere, contact your dealer or a professional fitter.
Faulty installation may cause water leakage,
electric shock, fire, etc.
•
If you notice anything abnormal (smell of
burning, etc.), stop the system, turn off the
power supply and consult your dealer.
Continued use of the system in abnormal
circumstances may result in malfunctioning,
electric shock, fire, etc.
• 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 improper 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.
WARNING
• 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.
If the refrigerant comes in contact with the bare
skin, it may cause cold injury.
If the refrigerant gas is inhaled excessively, it may
cause deterioration of nerve function like dizziness and headache, or deterioration of heart function like irregular heartbeat and heart palpitation
temporarily. If refrigerant unexpectedly leaks
from the unit onto a fan heater, stove, hotplate or
other heat source, harmful gases could be generated.

■ 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 24 °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.

NOTE
• The actual position of the flap and louver may differ from the display shown.
NOTE FOR HEATING OPERATION
• When operation starts, the flap and louver direction is fixed at the horizontal / center position in order to avoid cold draft, and return
to the set the position that was set after the warm air supply is starting.
• The flap and louver direction will be controlled to the horizontal/center position when the room temperature reaches the set tem-
perature and compressor stops or when defrosting is in operation.
• The airflow direction cannot be set during the period mentioned above. Change the airflow direction settings after the warm air is
supplied and the flap/louver goes to the set position.
(Swing)
MEMORY FLAP (FLAP OR LOUVER STOPPED)
When you press the AIRFLOW (U/D or L/R) button once while the flap or louver is operating, it stops swinging at the position. Since this angle is
memorized in the microcomputer, the flap or louver will automatically be set at this angle when the next operation is started.
WARNING
• 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 24
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 27, or if things
happen as shown on page 28,
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.

Notice
The unit does not restart immediately after you have
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 15 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.

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.
The cable becomes extremely hot.
The covering of the cable is cracked.
CAUTION
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.
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.
• When other indoor units are operating in different modes, the RUN light illuminates.
0.5 sec.
ON
OFF
0.5 sec.
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).
