NOTE .............. Indicates a situation that may
result in the unit or propertydamage-only accidents.
Keep these warning sheets handy so that you
can refer to them if needed.
Also, if this unit is transferred to a new user, make sure
to hand over this operation manual to the new user.
DANGER
• Refrigerant gas may produce a toxic gas if it
comes in contact with fire such as from a fan,
heater, stove or cooking device. Exposure to
this gas could cause severe injury or death.
• For refrigerant leakage, consult your dealer.
Refrigerant gas is heavier than air and replaces oxygen. A massive leak could lead to oxygen depletion,
especially in basements, and an asphyxiation hazard could occur leading to serious injury or death.
• Any abnormalities in the operation of the air
conditioner such as smoke or fire could result
in severe injury or death.
Turn off the power and contact your dealer immediately for instructions.
• Do not install the unit in an area where flammable materials are present due to risk of
explosion resulting in serious injury or death.
• If equipment utilizing a burner is used in the
same room as the air conditioner, there is the
danger of oxygen deficiency which could lead
to an asphyxiation hazard resulting in serious
injury or death.
Be sure to ventilate the room sufficiently to avoid
this hazard.
• Safely dispose of the packing materials.
Packing materials, such as nails and other metal or
wooden parts, may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags
so that children will not play with them. Children
playing with plastic bags face the danger of death
by suffocation.
WARNING
• Be sure to install a ground fault circuit breaker.
Failure to install a ground fault circuit interrupter
may result in electric shocks or fire.
• It is not good for your health to expose your
body to the air flow for a long time.

stops operation.
NOTE
• The fan may keep on running for about
1 minute after the heating operation stops
for removing the heat in the indoor unit.
• Do not turn off the power immediately after
the unit stops.
The system need at least 5 minutes for
residual operation of drain pump device.
Turning off the power immediately will cause
water leak or trouble.
EXPLANATION OF HEATING OPERATION
• For general heating operation, it may take longer to
reach the set temperature than in cooling operation.
We recommend starting the operation which was
used before using timer operation.
• The following operation is performed in order to
prevent the heating capacity from dropping or
cold air from blowing.
Defrost operation
• In heating operation, freezing of the outside
unit coil increases. Heating capability
decreases and the system goes into defrost
operation.
• The airflow will be set to breeze or stop.
• If stopped, the display of the remote controller shows “
”.
• Once the airflow is set to breeze or stop, the
air conditioner will return to the previous
state in approximately 5 to 15 minutes.
English
Hot start
• In order to prevent cold air from blowing out
of an indoor unit at the start of heating operation, the indoor fan is automatically
stopped. The display of the remote controller
shows “
”.
• The heating capacity drops as the outside temperature falls. If this happens, use another heating device together with the unit. (When using the
appliances which produce open fire together, ventilate a room constantly.)
Do not place appliances which produce open fire
in places exposed to the air flow from the unit or
under the unit.
• It takes some time for the room to warm up from
the time the unit is started since the unit is a hotair circulatory system to warm the entire room.
• If the hot air rises to the ceiling, leaving the area
above the floor cold, we recommend using the circulator (the indoor fan for circulating air). Contact
your dealer for details.
6-2 PROGRAM DRY OPERATION
• The program dry function deprives the room
of moisture while the air conditioner is in intermittent weak cooling operation so that the
room temperature will not become too low.
• The microcomputer automatically controls
the temperature and fan speed, so these
cannot be set using the remote controller.
• This function is not available if the room temperature is 68°F or lower.
• This function does not controls the humidity.
• FXL and FXN type indoor unit can not operate program dry operation.
FOR SYSTEMS WITHOUT COOL/HEAT SELECTOR (Refer to figure 5)

This system provides two other control systems
beside individual control (one remote controller controls one indoor unit) system. Confirm which type of
your unit is the following system.
• Group control system
One remote controller controls up to 16 indoor
units. All indoor units are equally set.
• Two remote controller control system
Two remote controllers control one indoor unit (in
case of group control system, one group of indoor
units). The unit is individually operated.
NOTE
• Contact your Daikin dealer in case of changing the combination or setting of group control
and two remote controller control systems.
11
7. OPTIMUM OPERATION
Observe the following precautions to ensure the
system operates properly.
• Prevent direct sunlight from entering a room during cooling operation by using curtains or blinds.
• Do not leave doors and windows open. If the
doors and windows remain open, air will flow out
of your room causing a decrease in the cooling or
heating effect.
• Do not use other heating devices directly beneath
the indoor unit.
If you do, they might get deformed by the heat.
• Never place objects near the air inlet or the air
outlet of the unit. It may cause deterioration in the
effect or stop the operation.
• Adjust the room temperature properly for a comfortable environment. Avoid excessive heating or
cooling.
• Ventilate often.
Extended use requires special attention to ventilation.
• When the display shows “
” (time to clean the
air filter), ask a qualified service person to clean
the filters. (Refer to the chapter “Maintenance” in
the indoor unit manual.)
• Keep the indoor unit and remote controller at least
3.5ft. away from televisions, radios, stereos, and
other similar equipment.
Failing to do so may cause static or distorted pictures.
• Turn off the main power supply switch to the unit
when the unit is not used for longer periods of
time. If the switch is on, it uses electricity. Before
restarting the unit, turn on the main power supply
switch 6 hours before operation to ensure smooth
running. (Refer to the chapter “Maintenance” in
the indoor unit manual.)
• Fully use the function of air flow direction adjust.
Cold air gathers on the floor, and warm air gathers
in the ceiling.
Set the air flow direction parallel during cooling or
dry operation, and set it downwards during heating operation.
Do not let the air blow directly to a person.
• It takes time for the room temperature to reach the
set temperature.
We recommend starting the operation in advance
using timer operation.

8. SEASONAL MAINTENANCE
•
•
•
•
•
CAUTION
Do not touch the air inlets or aluminum fins of
the outside or indoor units.
Touching them may result in injury.
Do not wash the outside or indoor units with
water.
An electric shock or fire may result.
Watch your steps at the time of air filter cleaning etc.
If the scaffold is unstable, you may fall or topple
down, thus causing injury.
Be sure to stop the operation, and turn the
breaker off before cleaning.
This may cause electric shock and injury.
Consult with the dealer for cleaning the interior of the indoor units.
Incorrect cleaning may damage the plastic parts
and cause failures, such as water leakage, and an
electric shock may result.
8-1 AT THE BEGINNING OF THE SEASON
Check
• Are the indoor and outside unit intake and outlet
vents blocked?
Remove anything that might be blocking them.
Clean the exterior.
• See the operation manual included with the
indoor unit for details on how to clean it.
Turn the power on.
• When the power comes on, the characters in the
remote controller display appear.
(To protect the unit, turn the power on at least 6
hours before operating it. This makes operation
smoother.)
8-2 AT THE END OF THE SEASON
On a clear day, use fan operation for around half a
day to thoroughly dry out the interior of the unit.
• Refer to chapter 6 for details on fan operation.
Turn off the power.
• When the power is shut off, the characters in the
remote controller display disappear.
• When the power is on, the unit consumes up to
several dozen Watts of power.
Turn off the power to conserve energy.
Clean the exterior.
• See the operation manual included with the
indoor unit for details on how to clean it.
English
9. FOLLOWING SYMPTOMS ARE NOT
AIR CONDITIONER TROUBLES
9-1 THE SYSTEM DOES NOT OPERATE
• The air conditioner does not start immediately
when restarting or changing the operation
mode.
If the operation lamp lights, the system is in normal condition.
To prevent overloading of the compressor motor,
the air conditioner starts 5 minutes after it is turned
ON again in case it was turned OFF just before.
• If “Centralized Control” is displayed on the
remote controller and pressing the operation
button causes the display to blink for a few
seconds.
This indicates that the central device is controlling
the unit.
The blinking display indicates that the remote
control cannot be used.
• The system does not start immediately after
the power supply is turned on.
Wait 1 minute until the micro computer is prepared for operation.
9-2 IT STOPS SOMETIMES
• The remote controller display reads “U4” or
“U5” and stops but then restarts after a few
minutes.
This is because the remote control is intercepting
noise from electrical appliances other than the air
conditioner, and this prevents communication
between the units, causing them to stop.
Operation automatically restarts when the noise
goes away.
9-3 COOL/HEAT CANNOT BE CHANGED
OVER
• When the display shows “
”
(changeover under control).
It shows that this is a slave remote controller.
Refer to “Setting the master remote controller”.
• When the cool/heat selector switch is
installed and the display shows “
”
(changeover under control).
This is because cool/heat changeover is controlled by the cool/heat selector. Ask your Daikin
dealer where the remote control switch is installed.
12
01_EN_3P215731-1D.fm Page 13 Tuesday, February 5, 2008 6:35 PM
9-4 FAN OPERATION IS POSSIBLE, BUT
COOLING AND HEATING DO NOT WORK
9-8 NOISE OF AIR CONDITIONERS
• Immediately after the power is turned on.
The micro computer is getting ready to operate.
Wait 10 minutes.
• A “zeen” sound is heard immediately after the
power supply is turned on.
The electronic expansion valve inside an indoor
unit starts working and makes the noise. Its volume will reduce in about 1 minute.
9-5 THE FAN STRENGTH DOES NOT CORRESPOND TO THE SETTING
• The fan speed does not change even if the fan
speed control button is pressed.
During heating operation, when the room temperature reaches the set temperature, the outside
unit goes off and the indoor unit changes to whisper the fan speed.
This is to prevent cold air blowing directly on occupants of the room.
The fan speed will not change even if the button is
pressed, when another indoor unit is in heating
operation.
9-6 THE FAN DIRECTION DOES NOT CORRESPOND TO THE SETTING
• The fan direction does not correspond to the
remote control display.
The fan direction does not swing.
This is because the unit is being controlled by the
micro computer. Refer to “Adjusting the air flow
direction”.
9-7 WHITE MIST COMES OUT OF THE UNIT
Indoor unit
• When humidity is high during cooling operation.
If the interior of indoor unit is extremely contaminated, the temperature distribution inside a room
becomes uneven. It is necessary to clean the interior of the indoor unit. Ask your Daikin dealer for
details on cleaning the unit. This operation
requires a qualified service person.
• Immediately after the cooling operation stops
and if the room temperature and humidity are
low.
This is because warm refrigerant gas flows back
into the indoor unit and generates steam.
Outside unit
• When the system is changed over to heating
operation after defrost operation.
Moisture generated by defrost becomes steam
and is exhausted.
Indoor unit
• A continuous low “shah” sound is heard when
the system is in cooling operation or at a stop.
When the drain pump (an optional accessory) is
in operation, this noise is heard.
• A “pishi-pishi” squeaking sound is heard when
the system stops after heating operation.
Expansion and contraction of plastic parts caused
by temperature change make this noise.
• A low “sah”, “choro-choro” sound is heard
while the indoor unit is stopped.
When the other indoor unit is in operation, this
noise is heard. In order to prevent oil and refrigerant from remaining in the system, a small amount
of refrigerant is kept flowing.
Outside unit
• When the tone of operating noise changes.
This noise is caused by the change of frequency.
Indoor unit, outside unit
• A continuous low hissing sound is heard when
the system is in cooling or defrost operation.
This is the sound of refrigerant gas flowing
through both indoor and outside units.
• A hissing sound which is heard at the start or
immediately after stopping operation or
defrost operation.
This is the noise of refrigerant caused by flow stop
or flow change.
9-9 DUST COMES OUT OF THE UNIT
• When the unit is used after stopping for a long
time.
This is because dust has gotten into the unit.
9-10 THE UNITS CAN GIVE OFF ODOURS
• During operation.
The unit can absorb the smell of rooms, furniture,
cigarettes, etc., and then emit it again.
9-11 THE OUTSIDE UNIT FAN DOES NOT
ROTATE
• During operation.
The speed of the fan is controlled in order to optimize product operation.

9-12 THE DISPLAY SHOWS “
”
• This is the case immediately after the main
power supply switch is turned on and means
that the remote controller is in normal condition. This continues for 1 minute.
9-13 THE COMPRESSOR OR FAN IN THE
OUTSIDE UNIT DOES NOT STOP
• This is to prevent oil and refrigerant from
remaining in the compressor. The unit will
stop after 5 to 10 minutes.
9-14 THE INSIDE OF OUTSIDE UNIT IS
WARM EVEN WHEN THE UNIT HAS
STOPPED
• This is because the crankcase heater is warming the compressor so that the compressor
can start smoothly.
9-15 HOT AIR IS EMITTED EVEN THOUGH
THE UNIT IS STOPPED
• Hot air can be felt when the unit is stopped.
Several different indoor units are being run on the
same system, so if another unit is running, some
refrigerant will still flow through the unit.
9-16 DOES NOT COOL VERY WELL
• Program dry operation.
Program dry operation is designed to lower the
room temperature as little as possible.
Refer to page 8.
