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,

■ To fix the remote controller holder
on the wall
1. Choose a place from where the signals
reach the unit.
2. Fix the holder to a wall, a pillar, etc. with the
screws supplied with the holder.
3. Place the remote controller in the remote
controller holder.
ATTENTION
■
About batteries
• When replacing the batteries, use batteries of the same type, and replace the two old batteries together.
• When the system is not used for a long time, take the batteries out.
• We recommend replacing once a year, although if the remote controller display begins to fade or if reception
deteriorates, please replace with new alkaline batteries. Using manganese batteries reduces the lifespan.
• The attached batteries are provided for the initial use of the system.
The usable period of the batteries may be short depending on the manufactured date of the air conditioner.
■
About remote controller
• Never expose the remote controller to direct sunlight.
• Dust on the signal transmitter or receiver will reduce the sensitivity. Wipe off dust with soft cloth.
• Signal communication may be disabled if an electronic-starter-type fluorescent lamp (such
as inverter-type lamps) is in the room. Consult the shop if that is the case.
• If the remote controller signals happen to operate another appliance, move that appliance
to somewhere else, or consult the shop.

• If the indoor unit’s internal clock is not set to the correct time, the WEEKLY TIMER will not
operate punctually.
■ Turn the breaker ON
• Turning ON the breaker closes the flap. (This is a normal procedure.)
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 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.

When the airflow 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 airflow 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, the performance of the air conditioner 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 airflow late, so manual
adjustment of these functions is unavailable.
■
Note on AUTO operation
• In AUTO operation, the system selects a temperature setting and 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 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
〈〈
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.
When more than one 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 (*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.

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 (heating) 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.
24
■ 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 Current operation mode maintained
HEAT
AUTO
Status of Room B, C and D when the unit in Room
A is in COOL mode
The unit enters Standby Mode. Operation resumes when
the Room A unit stops operating.
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.

28
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.
Hot air does not flow out soon
after the start of heating
operation.
The heating operation stops suddenly
and a flowing sound is heard.
The outdoor unit emits water or
steam.
Mist comes out of the indoor
unit.
The indoor unit gives out odour. ■
• This is to protect the air conditioner.
You should wait for about 3 minutes.
•
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 system is taking away the frost on the outdoor unit.
You should wait for about 4 to 12 minutes.
■ 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.
■ 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.
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.)
The outdoor fan rotates while
the air conditioner is not in
operation.
The operation stopped
suddenly.
(OPERATION lamp is on.)
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.
The ON/OFF TIMER does not
operate according to the
settings.
■ 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.
■ For system protection, the air conditioner may stop operating
on a sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.
• The batteries are dying and the remote controller is malfunctioning. Replace all the batteries with new size AAA alkaline
batteries. For details, refer to “To set the batteries” of this
manual. (page 7.)
* If the reset button is provided, press the reset button after the
batteries are replaced.
• Check if the ON/OFF TIMER and the WEEKLY TIMER are
set to the same time.
Change or disable the settings in the WEEKLY TIMER.
(page 20.)
29
Check again.
Please check again before calling a repair person.
Case Check
The air conditioner does not
operate.
(OPERATION lamp is off.)
Cooling (Heating) effect is poor. • Are the air filters clean?
Operation stops suddenly.
(OPERATION lamp flashes.)
• 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?
• 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?
• 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 24.)
An abnormal functioning
happens during operation.
30
• 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.
Call the service shop immediately.
WARNING
■ When an abnormality (such as a burning smell) occurs, stop operation and turn the breaker OFF.
Continued operation in an abnormal condition may result in troubles, electric shocks or fire.
Consult the service shop where you bought the air conditioner.
■ Do not attempt to repair or modify the air conditioner by yourself.
Incorrect work may result in electric shocks or fire.
Consult the service shop where you bought the air conditioner.
If one of the following symptoms takes place, call the service shop immediately.
■ The power cord is abnormally hot or damaged.
■ An abnormal sound is heard during operation.
■ The safety breaker, a fuse, or the earth leakage breaker
cuts off the operation frequently.
■ A switch or a button often fails to work properly.
■ There is a burning smell.
■ Water leaks from the indoor unit.
Turn the breaker
OFF and call the

■ After a power failure
The air conditioner automatically resumes
operation in about 3 minutes. You should just
wait for a while.
■ Lightning
If lightning may strike the neighbouring area,
stop operation and turn the breaker OFF for
system protection.
We recommend periodical maintenance.
In certain operating conditions, the inside of the air conditioner may get foul after several seasons of
use, resulting in poor performance. It is recommended to have periodical maintenance by a specialist
aside from regular cleaning by the user. For specialist maintenance, contact the service shop where
you bought the air conditioner.
The maintenance cost must be born by the user.
