Safety Precautions
• Keep this manual where the operator can easily find it.
• Read the precautions in this manual carefully before operating the unit.
• The precautions described herein are classified as WARNING and CAUTION. They both contain important information
regarding safety. Be sure to observe all precautions without fail.
WARNING
Failure to follow these instructions properly may result in
personal injury or loss of life.
Never attempt.
CAUTION
Failure to observe these instructions properly may result in
property damage or personal injury, which may be serious
depending on the circumstances.
Never wet the air conditioner nor the remote controller with
water.
Be sure to follow the instructions.
Be sure to establish an earth connection.
Never touch the air conditioner nor the remote controller with
wet hands.
• After reading, keep this manual in a convenient place so that you can refer to it whenever necessary. If the equipment is
transferred to a new user, be sure also to hand over the manual.
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.
• Do not attempt to install or repair the air conditioner yourself. Improper workmanship may result in water leakage,
electric shocks or fire hazards. Please contact your local dealer or qualified personnel for installation and
maintenance work.
• When the air conditioner is malfunctioning (giving off a burning odour, etc.) turn off power to the unit and contact your
local dealer. Continued operation under such circumstances may result in a failure, electric shocks or fire hazards.
• Be sure to install an earth leakage breaker. Failure to install the earth leakage breaker may result in electric shocks or fire.
• Be sure to earth the unit. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect
earthing may result in electric shocks.
CAUTION
• Do not use the air conditioner for purposes other than those for which it is intended. Do not use the air conditioner for
cooling precision instruments, food, plants, animals or works of art as this may adversely affect the performance,
quality and/or longevity of the object concerned.

operation by a child may result in impairment of bodily functions and harm health.
• Do not give impact to the indoor and outdoor units, or otherwise product damage may result.
• Do not place flammable items, such as spray cans, within 1 meter of the air outlet.
The spray cans may explode as a result of hot air from the indoor or outdoor units.
• Be careful not to let pets urinate on the air conditioner. Urination on the air conditioner may result in electric shocks or fire.
• To avoid oxygen depletion, ensure that the room is adequately ventilated if equipment such as a burner is used
together with the air conditioner.
• Before cleaning, be sure to stop unit operation, turn the breaker off or remove the power cord. Otherwise, an electric
shock and injury may result.
• Only connect the air conditioner to the specified power supply circuit. Power supplies other than the one specified
may result in electric shocks, overheating and fires.
• Arrange the drain hose to ensure smooth drainage. Imperfect drainage may cause wetting of the building, furniture etc.
• Do not place objects in direct proximity of the outdoor unit and do not let leaves and other debris accumulate around
the unit. Leaves are a hotbed for small animals which can enter the unit. Once in the unit, such animals can cause
malfunctions, smoke or fire when making contact with electrical parts.
• Do not place objects around the indoor unit.
Doing so may have an adverse influence on the performance, product quality, and life of the air conditioner.
• To avoid electric shocks, do not operate with wet hands.
• Do not wash the air conditioner with water, as this may result in electric shocks or fire.
• Do not place water containers (vases etc.) above the unit, as this may result in electric shocks or fire hazards.

Notes on each operation mode
• 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 heating
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.
• 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.
• 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.
• 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.
• This mode is valid for fan only.

• In case the air conditioner and other
appliances which require high power
consumption are used at same time, a circuit
breaker may trip if the air conditioner operate

NOTE
„ Notes on operation mode for multi system
• COOL, DRY and FAN mode may be used at the same time.
• AUTO mode automatically selects COOL mode or HEAT mode based on the room temperature.
Therefore, AUTO mode is available when selecting the same operation mode as that of the room with the first unit to be turned on.
CAUTION
• Normally, the operation mode in the room where the unit is first run is given priority, but the following situations are exceptions, so please keep
this in mind.
If the operation mode of the first room is FAN mode, then using HEAT mode in any room after this will give priority to HEAT. In this situation,
the air conditioner running in FAN mode will go on standby, and the operation lamp will flash.
With the priority room setting active.
Refer to “Priority room setting” on the next page.
„ NIGHT QUIET mode (Available only for COOL operation)
NIGHT QUIET mode requires initial programming during installation. Please consult your retailer or dealer for assistance.
NIGHT QUIET mode reduces the operation noise of the outdoor unit during the nighttime hours to prevent annoyance to
neighbors.
• The NIGHT QUIET mode is activated when the temperature drops 5°C or more below the highest temperature recorded that day.
Therefore, when the temperature difference is less than 5°C, this function will not be activated.
• NIGHT QUIET mode reduces slightly the cooling efficiency of the unit.

The priority room setting requires initial programming during installation. Please consult your authorized dealer for assistance.
The room designated as the priority room takes priority in the following situations.
Operation mode priority
• As the operation mode of the priority room takes precedence, the user can select a different operation mode from other
rooms.
[Example]
• Room A is the priority room in the examples.
When COOL mode is selected in room A while operating the following modes in room B, C and D :
Operation mode in room B, C and D
COOL or DRY or FAN
Status of room B, C and D when the unit in room A is in COOL mode
Current operation mode maintained
HEAT
The unit enters standby mode. Operation resumes when the room A unit stops operating.
AUTO
If the unit is set to COOL mode, operation continues. If the unit is set to HEAT mode, it enters
standby mode. Operation resumes when the room A unit stops operating.
Priority when POWERFUL operation is used
[Example]
• Room A is the priority room in the examples.
The indoor units in rooms A, B, C and D are all operating. If the unit in room A enters POWERFUL operation, operation
capacity will be concentrated in room A. In such a case, the COOL (HEAT) efficiency of the units in room B, C and D may
be slightly reduced.
Priority when using OUTDOOR UNIT QUIET operation
[Example]
• Room A is the priority room in the examples.
Just by setting the unit in room A to QUIET operation, the air conditioner starts OUTDOOR UNIT QUIET operation.
You don’t have to set all the operated indoor units to QUIET operation.

Troubleshooting
„ These cases are not troubles.
• The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
Indoor unit
The flaps do 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.
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.
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.
„ Whistling sound
• This sound is generated when refrigerant flows during
defrosting operation.
Outdoor unit
The outdoor unit emits water or steam.
„ In HEAT mode
• The frost on the outdoor unit melts into water or steam when the air
conditioner is in defrost operation.
„ In COOL or DRY mode
• Moisture in the air condenses into water on the cool surface of outdoor
unit piping and drips.

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.
• Are operation modes all the same for indoor units
connected to outdoor units in the multi system?
If not, set all indoor units to the same operation mode
and confirm that the lamps flash.
When the operation mode is in “AUTO”, set all indoor
unit operation modes to “COOL” or “HEAT” for a
moment and check again that the lamps are normal. If
the lamps stop flashing after the above steps, there is
no malfunction. Page 28

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.
