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.
• It is not good for health to expose your body to the air flow for a long time.
• Do not put a finger, a rod or other objects into the air outlet or inlet. As the fan is rotating at a high speed, it will
cause injury.
• Do not attempt to repair, relocate, modify or reinstall the air conditioner by yourself. Incorrect work will cause electric
shocks, fire etc.
For repairs and reinstallation, consult your Daikin dealer for advice and information.
• The refrigerant used in the air conditioner is safe. Although leaks should not occur, if for
some reason any refrigerant happens to leak into the room, make sure it does not come in
contact with any flame as of gas heaters, kerosene heaters or gas range.
• If the air conditioner is not cooling (heating) properly, the refrigerant may be leaking, so call your dealer.
When carrying out repairs accompanying adding refrigerant, check the content of the repairs with our service staff.
• Do not attempt to install the air conditioner by your self. Incorrect work will result in water leakage, electric shocks or
fire. For installation, consult the dealer or a qualified technician.
• In order to avoid electric shock, fire or injury, if you detect any abnormally such as smell of fire, stop the operation and
turn off the breaker. And call your dealer for instructions.
• Depending on the environment, an earth leakage breaker must be installed. Lack of an earth leakage breaker may
result in electric shocks or fire.

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.
Recommended temperature setting
For cooling:26°C – 28°C
For heating:20°C – 24°C
■ Please note
• The air conditioner always consumes 15-35 watts 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.

• Indoor unit quiet operation
When the air flow is set to “
”, the noise from the indoor unit will become quieter.
Use this when making the noise quieter.
The unit might lose capacity when the air flow rate is set to a weak level.
NOTE
■ Note 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 blowing the hot air in the room outside, so if the
outside temperature is high, performance drops.
■ 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 fan strength, so manual
adjustment of these functions is unavailable.
■ Note on AUTO operation
• In AUTO operation, the system selects an appropriate operation mode (COOL or HEAT) based on
the room temperature at the start of the operation.
• The system automatically reselects setting at a regular interval to bring the room temperature to usersetting level.
• If you do not like AUTO operation, you can manually select the operation mode and setting
you like.
■ Note on air flow rate setting
• At smaller air flow rates, the cooling (heating) effect is also smaller.

■ To adjust the vertical blades
(louvres)
Hold the knob and move the louvres.
(You will find a knob on the left-side and the right-side blades.)
• When the unit is installed in the corner of a room,
the direction of the louvers should be facing away
from the wall.
If they face the wall, the wall will block off the wind,
causing the cooling (or heating) efficiency to drop.
Notes on flaps and louvres angles
• When “ SWING button ” is selected, the flaps
swinging range depends on the operation mode.
(See the figure.)
• If the unit is operated after being stopped with
the flaps pointed down in cooling or dry operation, the flaps will automatically move to a horizontal position after about one hour to prevent
condensation from forming on them.
■ ATTENTION
• Always use a remote controller to adjust the flaps
angle. If you attempt to move it forcibly with hand
when it is swinging, the mechanism may be broken.
• Be careful when adjusting the louvres. Inside the
air outlet, a fan is rotating at a high speed.

Note for Multi System
〈〈 What is a “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.
A
room
Outdoor
unit
Living
room
B
room
When more than one indoor unit is operating, priority is
given to the first unit that was turned on.
C
room
In this case, set the units that are turned on later to the
same operation mode (*1) as the first unit.
Otherwise, they will enter the Standby Mode, and the operation lamp will flash; this does not indicate malfunction.
(*1)
• 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 Heating Mode in any room after this will give priority to
heating. In this situation, the air conditioner running in FAN Mode will go on standby, and the operation lamp will flash.
2. With the Priority Room Setting active.
See “Priority Room Setting” on the next page.
■ NIGHT QUIET Mode (Available only for cooling 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 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.
■ OUTDOOR UNIT QUIET Operation (page 15.)
1. With the Priority Room Setting present but inactive or not present.
When using the OUTDOOR UNIT QUIET operation feature with the Multi system, set all indoor units to
OUTDOOR UNIT QUIET operation using their remote controllers.
When clearing OUTDOOR UNIT QUIET operation, clear one of the operating indoor units using their remote controller.
However OUTDOOR UNIT QUIET operation display remains on the remote controller for other rooms.
We recommend you release all rooms using their remote controllers.
2. With the Priority Room Setting active.
See “Priority Room Setting” on the next page.
■ Cooling / Heating Mode Lock (Available only for heat pump models)
The Cooling / Heating Mode Lock requires initial programming during installation.Please consult your retailer or dealer
for assistance. The Cooling / Heating Mode Lock sets the unit forcibly to either Cooling or Heating Mode. This function
is convenient when you wish to set all indoor units connected to the Multi system to the same operation mode.

■ Priority Room Setting
The Priority Room Setting requires initial programming during installation. Please consult your
retailer or dealer for assistance.
The room designated as the Priority Room takes priority in the following situations;
1. 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 set to
HEAT mode, it enters Standby Mode. Operation resumes when
the Room A unit stops operating.
2. 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 cooling (heating)
efficiency of the units in Rooms B,C and D may be slightly reduced.
3. 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.

TROUBLE SHOOTING
Trouble Shooting
These cases are not troubles.
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
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 heating
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 heating operation stops
suddenly and a flowing sound
is heard.
• The system is taking away the frost on the outdoor unit.
You should wait for about 3 to 8 minutes.
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.
Mist comes out of the indoor
unit.
■ This happens when the air in the room is cooled into mist by
the cold air flow during cooling 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
air flow.
(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.)
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.

Check again.
Please check again before calling a repair person.
Case
The air conditioner does not
operate.
(OPERATION lamp is off.)
Check
• 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 air flow rate and the air direction set appropriately?
• Is the unit set to the INTELLIGENT EYE mode?
(page 18.)
Operation stops suddenly.
(OPERATION lamp flashes.)
• Are the air filters clean?
• Is there anything to block the air inlet or the outlet of the
indoor and the outdoor units?
Clean the air filters or take all obstacles away and turn the
breaker OFF. 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 22.)
An abnormal functioning
happens during operation.
