READ BEFORE OPERATION
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.
• After reading, keep this manual in a convenient place so that you can refer to it whenever neces-
sary. 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.

NOTE
■
Tips for saving energy
• Be careful not to cool (heat) the room too much.
Keeping the temperature setting at a moderate level helps save energy.
• Cover windows with a blind or a curtain.
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 two weeks.
■
Please note
• The air conditioner always consumes a small amount of electricity even while it is not operating.
•
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.
• Operation outside this humidity or temperature range may cause a safety device to disable the system.

NOTE
DRY operation AUTO or COOL or HEAT or FAN operation
The airflow rate setting is not variable.
Five levels of airflow rate setting from “ ” to “ ”
plus “ ” “ ” are available.
■
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 heating operation, it takes some time before the room gets warmer.
• In heating 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.
■
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 late, 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.
• If you do not like AUTO operation, manually change the set temperature.
■
Note on airflow rate setting
• At smaller airflow rates, the cooling (heating) effect is also smaller.

Note for Multi System
This system has one outdoor unit connected to multiple
indoor units.
■ Selecting the operation mode
1. With the priority room setting present
but inactive or not present.
When more than 1 indoor unit is operating, priority is
given to the first unit that was turned on.
In this case, set the units that are turned on later to
the same operation mode as the first unit.
Otherwise, they will enter the standby state, and the
OPERATION lamp will flash: this does not indicate
malfunction.
NOTE
CAUTION
1. With the priority room setting
active.
See “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 night time hours to
prevent annoyance to neighbors.
• The NIGHT QUIET mode is activated when the temperature drops 6°C or more below the
highest temperature recorded that day. Therefore, when the temperature difference is less than
4°C, this function will not be activated.
• NIGHT QUIET mode reduces slightly the cooling efficiency of the unit.
■
Notes on operation mode for multi system
• COOL, DRY and FAN operation may be used at the same time.
• AUTO operation automatically selects COOL operation or HEAT operation based on the
room temperature.
Therefore, AUTO operation is available when selecting the same operation mode as that
of the room with the first unit to be turned on.
• 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 operation, then using HEAT operation in any
room after this will give priority to HEAT operation. In this situation, the air conditioner
running in FAN operation will go on standby, and the OPERATION lamp will flash.

TROUBLESHOOTING
Troubleshooting
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
These cases are not troubles.
Case Explanation
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.
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.)
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
and 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.
■ Ticking sound
• This sound is generated when the size of the air conditioner
slightly expands or shrinks as a result of temperature changes.
■ 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.
The outdoor unit emits water or
steam.
■ 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.
Mist comes out of the indoor
unit.
■ This happens when the air in the room is cooled into mist by
the cold airflow during cooling operation.
■ This is because the air in the room is cooled by the heat
exchanger and becomes mist during defrost operation.
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.)

Case Explanation
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.
The 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.
No remote controller signals are
displayed.
The remote controller sensitivity is low.
The display is low in contrast or
blacked out.
The display runs out of control.

Change or disable the settings in the WEEKLY TIMER. (page 20.)
Check again.
Case Check
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?
Cooling (Heating) effect is poor. • Are the air filters clean?
• 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 air direction set appropriately?
Operation stops 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 bleaker 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.
• 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.
Moreover, 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 24.)
An abnormal functioning
