WARNING
• In order to avoid fire, explosion or injury, do not operate the unit when harmful, among which
flammable or corrosive gases, are detected near the unit.
• Be aware that prolonged, direct exposure to cool or warm air from the air conditioner, or to air
that is too cool or too warm can be harmful to your physical condition and health.
• Do not place objects, including rods, your fingers, etc., in the air inlet or outlet. Product malfunctioning,
product or injury damage may result due to contact with the air conditioner’s high-speed fan blades.
• Do not attempt to repair, dismantle, reinstall or modify the air conditioner yourself as this may result
in water leakage, electric shocks or fire hazards.
• Do not use flammable spray near the air conditioner, or otherwise fire may result.
• Beware of fire in case of refrigerant leakage. If the air conditioner is not operating correctly, i.e. not generating
cool or warm air, refrigerant leakage could be the cause. Consult your dealer for assistance. The refrigerant
within the air conditioner is safe and normally does not leak.
However, in the event of a leakage, contact with a naked burner, heater or cooker may result in generation of noxious
gas. Do not longer use the air conditioner until a qualified service person confirms that the leakage has been repaired.

Preparation before Operation
„ Turn the breaker on
• After the power is turned on, the flap of the indoor unit opens and closes once to set the
reference position.
NOTE
„ Tips for saving energy
• Be careful not to cool (heat) the room too much.
Recommended temperature setting
Keeping the temperature setting at a moderate
level helps save energy.
For cooling: 26-28°C
• Cover windows with a blind or a curtain.
For heating: 20-24°C
Blocking sunlight and air from outdoors
increases the cooling (heating) effect.
• Clogged air filters cause inefficient operation and waste energy. Clean them once in about
every 2 weeks.
„ Please note
• The air conditioner always consumes 15-35W of electricity even while it is not operating.
The outdoor unit consumes 1-10W to have its electric components work even while it is not
operating.
During standby electricity saving mode : about 1W
The outdoor unit consumes about 35W of power at the time of compressor preheating.
• If you are not going to use the air conditioner for a long period, for example in spring or
autumn, turn the breaker off.
• Use the air conditioner in the following conditions.

NOTE
„ Notes on HEAT operation
• Since this air conditioner heats the room by taking heat from outdoor air to indoors, the
heating capacity becomes smaller in lower outdoor temperatures. If the heating effect is
insufficient, it is recommended to use another heating appliance in combination with the air
conditioner.
• The heat pump system heats the room by circulating hot air around all parts of the room.
After the start of HEAT operation, it takes some time before the room gets warmer.
• In HEAT operation, frost may occur on the outdoor unit and lower the heating capacity. In
that case, the system switches into defrosting operation to take away the frost.
• During defrosting operation, hot air does not flow out of indoor unit.
• A pinging sound may be heard during defrosting operation, which, however does not mean
that the air conditioner has failures.
„ Note on COOL operation
• This air conditioner cools the room by releasing the heat in the room outside.
Therefore, the cooling performance of the air conditioner may be degraded if the outdoor
temperature is high.
„ Note on DRY operation
• The computer chip works to rid the room of humidity while maintaining the temperature as
much as possible. It automatically controls temperature and airflow rate, so manual
adjustment of these functions is unavailable.
„ Notes on AUTO operation
• In AUTO operation, the system selects an appropriate operation mode (COOL or HEAT)
based on the room and outside temperatures and starts the operation.
• The system automatically reselects setting at a regular interval to bring the room
temperature to user-setting level.
„ Note on FAN operation
• This mode is valid for fan only.
„ Note on airflow rate setting
• At smaller airflow rates, the cooling (heating) effect is also smaller.

Troubleshooting
Troubleshooting measures are classified into the following two types on a remedial basis.
Take an appropriate measure according to the symptom.
Not trouble
• These cases are not troubles.
You may just continue using it.
Check
• Please check again before calling a repair person.
The flap does not start swing
immediately.
• The air conditioner is adjusting the flap
position. The flap will start moving soon.
The HEAT operation stops suddenly
and a flowing sound is heard.
• The outdoor unit is taking away the frost.
The HEAT operation starts after the frost on
the outdoor unit is removed. You should wait
for about 4 to 12 minutes.
A sound is heard.
„ A sound like a flow of water
• This sound is generated because the
refrigerant in the air conditioner is flowing.
• This is a pumping sound of the water in the
air conditioner it is heard when the water is
pumped out from the air conditioner in
cooling or drying operation.
• The refrigerant flows in the air conditioner
even if the air conditioner is not working
when the indoor units in other rooms are in
operation.
„ Blowing sound
• This sound is generated when the flow of the
refrigerant in the air conditioner is switched
over.
„ Pinging sound
• This sound is generated when the size of the
air conditioner slightly expands or shrinks as
a result of temperature changes.
Operation does not start soon.
„ When “ON/OFF” button was pressed
soon after operation was stopped.
„ When the mode was reselected.
• This is to protect the air conditioner.
You should wait for about 3 minutes.
„ Clicking sound during operation or idle
time
• This sound is generated when the refrigerant
control valves or the electrical parts operate.
„ Clopping sound
• This sound is heard from the inside of the air
conditioner when the exhaust fan is
activated while the room doors are closed.
Open the window or turn off the exhaust fan.

„ In HEAT operation
• The frost on the outdoor unit melts into water
or steam when the air conditioner is in
defrost operation.
„ In COOL or DRY operation
• Moisture in the air condenses into water on
the cool surface of outdoor unit piping and
drips.
The air conditioner does not
operate.
(OPERATION lamp is off.)
•
•
•
•
Hasn’t a breaker turned off or a fuse blown?
Isn’t it a power failure?
Are batteries set in the remote controller?
Is the timer setting correct?
Hot air does not flow out soon
after the start of HEAT operation.
• The air conditioner is warming up.
You should wait for 1 to 4 minutes.
(The system is designed to start discharging
air only after it has reached a certain
temperature.)
English
The outdoor unit emits water or
steam.
Operation stopped suddenly.
(OPERATION lamp flashes.)
• Are the air filters clean?
Clean the air filters.
• Is there anything to block the air inlet or the
outlet of the indoor and the outdoor units?
• Turn the breaker off and take all obstacles
away. Then turn it on again and try operating
the air conditioner with the remote controller.
If the lamp still flashes, call the service shop
where you bought the air conditioner.
Operation stopped suddenly.
(OPERATION lamp is on.)
• For system protection, the air conditioner
may stop operating on a sudden large
voltage fluctuation. It automatically resumes
operation in about 3 minutes.
Mist comes out of the indoor unit.
• This happens when the air in the room is
cooled into mist by the cold airflow during
COOL operation.
• This is because the air in the room is cooled
by the heat exchanger and becomes mist
during defrosting operation.

• Is there anything to block the air inlet or the
outlet of the indoor and the outdoor units?
• Is the temperature setting appropriate?
• Are the windows and doors closed?
• Are the airflow rate and the airflow direction
set appropriately?
Remote controller does not work
properly.
„ No remote controller signals are
displayed.
„ The remote controller sensitivity is low.
„ The display is low in contrast or blacked
out.

manual. (page 7)
The outdoor fan rotates while the
air conditioner is not in operation.
„ After operation is stopped
• The outdoor fan continues rotating for
another 60 seconds for system protection.
„ While the air conditioner is not in
operation
• When the outdoor temperature is very high,
the outdoor fan starts rotating for system
protection.
An abnormal functioning happens
during operation.
• The air conditioner may malfunction with
lightning or radio waves. Turn the breaker
off, turn it on again and try operating the air
conditioner with the remote controller.
The indoor unit gives out odour.
• This happens when smells of the room,
furniture, or cigarettes are absorbed into the
unit and discharged with the airflow.
(If this happens, we recommend you to have
the indoor unit washed by a technician.
Consult the service shop where you bought
the air conditioner.)
