Safety precaution
To gain full advantage of the air conditioner’s functions and to avoid malfunction due to mishandling, we recommend that
you read this instruction manual carefully before use.
This air conditioner is classified under “appliances not accessible to the general public”.
•
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.
•
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.
Failure to observe these instructions properly may result in
property damage or personal injury, which may be serious
depending on the circumstances.
CAUTION
WARNING
• 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.
• 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.
• Consult your local dealer about installation work.
Doing the work yourself may result in water leakage,
electric shocks or fire hazards.
• Consult your local dealer regarding modification,
repair and maintenance of the air conditioner.
Improper workmanship may result in water leakage,
electric shocks or fire hazards.
• Do not place objects, including rods, your fingers,
etc., in the air inlet or outlet.
Injury may result due to contact with the air
conditioner’s highspeed fan blades.
• Never touch the air outlet or the horizontal blades
while the swing flap is in operation.
Fingers may become caught or the unit may break
down.
• 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.
• Consult your local dealer regarding what to do in
case of refrigerant leakage.
When the air conditioner is to be installed in a small
room, it is necessary to take proper measures so that
the amount of any leaked refrigerant does not exceed
the concentration limit in the event of a leakage.
Otherwise, this may lead to an accident due to oxygen
depletion.
• Contact professional personnel about attachment
of accessories and be sure to use only
accessories specified by the manufacturer.
If a defect results from your own workmanship, it may
result in water leaks, electric shock or fire.
• Consult your local dealer regarding relocation and
reinstallation of the air conditioner.
Improper installation work may result in leakage,
electric shocks or fire hazards.
1
WARNING
• Be sure to use fuses with the correct ampere
reading.
Do not use improper fuses, copper or other wires as a
substitute, as this may result in electric shock, fire, injury
or damage to the unit.
• 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 or fire.
A high surge current from lightning or other sources may
cause damage to the air conditioner.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in
electric shocks or fire.
• Consult the dealer if the air conditioner submerges

generation, fire, or product failures.
• Consult your dealer regarding cleaning the inside of
the air conditioner.
Improper cleaning may cause breakage of plastic parts,
water leakage and other damage as well as 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.
• Do not remove the outdoor unit’s fan guard.
The guard protects against the unit’s high speed fan,
which may cause injury.
• Do not place objects that are susceptible to
moisture directly beneath the indoor or outdoor
units.
Under certain conditions, condensation on the main unit
or refrigerant pipes, air filter dirt or drain blockage may
cause dripping, resulting in fouling or failure of the object
concerned.
• To avoid oxygen depletion, ensure that the room is
adequately ventilated if equipment such as a burner
is used together with the air conditioner.
• After prolonged use, check the unit stand and its
mounts for damage.
If left in a damaged condition, the unit may fall and
cause injury.
• Do not place flammable sprays or operate spray
containers near the unit as this may result in fire.
• 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.
• To avoid electric shocks, do not operate with wet
hands.
• Do not place appliances that produce naked flames
in places exposed to the air flow from the unit as
this may impair combustion of the burner.
• Do not place heaters directly below the unit, as
resulting heat can cause deformation.

leakage.
In the event of a gas leakage, build-up of gas near
the air conditioner may result in fire hazards.
• Do not put flammable containers, such as spray
cans, within 1 m from the blow-off mouth.
The containers may explode because the warm air
output of the indoor or outdoor unit will affect them.
• Arrange the drain to ensure complete drainage.
If proper drainage from the outdoor drain pipe does
not occur during air conditioner operation, there
could be a blockage due to dirt and debris build-up
in the pipe.
This may result in a water leakage from the indoor
unit. Under these circumstances, stop air
conditioner operation and consult your dealer for
assistance.
• The appliance is not intended for use by
unattended young children or infirm persons.
Impairment of bodily functions and harm to health

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
Check if the fuse has blown.
Does not operate at all.
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
power supply is turned on.
The heating operation stops suddenly
and a flowing sound is heard.
A “Zeen” sound is heard immediately
after the power supply is turned on.
A continuos low “Shah” sound is heard
when the system is in COOLING OPERATION or at a stop.
A “Pishi-pishi” squeaking sound is
heard when the system stops after
HEATING OPERATION.
A low “Sah”, “Choro-choro” sound is
heard while an indoor unit has
stopped.
A continuous low “Shuh” sound is
heard when the systems is in COOLING
or DEFROST OPERATION.
A “Shuh” sound which is head at the
start or immediately after the stop of
operation or which is heard at the start
or immediately after the stop of
DEFROST OPERATION.
When the tone of operating noise
changes.
A continuous “shuh” sound generated
during operation or immediately after
the operation is started or stopped.
The outdoor unit emits water or steam.
Mists come out of the indoor unit.
The indoor unit gives out odour.
•
Set power switch to off.
Check if breaker has worked.
•
Turn the power on with the breaker switch in the
off position.
Do not turn the power on with the breaker switch
in the trip position. (Contact your dealer.)
When the power is interrupted.
•
Wait until the power is recovered, then operate the air conditioner again.
The air conditioner automatically resumes operation in about 3 minutes.
You should just wait for a while.
This is to protect the air conditioner.
•
You should wait for about 5 minutes.
The micro computer is preparing for operation.
Wait for about 10 minutes.
The air conditioner is warming up. You should wait for about 1 minute.
•
(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 3 to 8 minutes. (Max. 10 minutes).
This sound indicates that the valve for the refrigerant bypass is in operation.
•
The electronic expansion∗ valve inside an indoor unit starts working and
•
makes the noise. Its volume will reduce in about one minute.
∗ Electronic expansion valve … Controls the flow rate of the gas
(refrigerant) flowing inside the indoor unit.
When the drain pump (optional accessories) is in operation, this noise is
•
heard.
Expansion and contracion of plastic parts caused by temperature change
•
makes this noise.
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.
This is the sound of refrigerant gas flowing through both indoor and out-
•
door units.
This is the noise of refrigerant caused by flow stop and flow change.
•
This noise caused by the change of frequency.
•
This sound indicates that the valve for the refrigerant bypass is in opera-
•
tion.
In HEATING mode
■
• The frost on the outdoor unit melts into water or steam when the air conditioner is in defrost operation.
In COOLING 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 air
•
flow during cooling operation.
If the inside of an indoor unit is extremely contaminated, the temperature
•
distribution inside a room becomes uneven. It is necessary to clean the
inside of the indoor unit. Ask your Daikin dealer for details on cleaning the
indoor unit. This operation requires a qualified service person.
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.)

Trouble Shooting
Case Explanation
After operation is stopped:
The outdoor fan rotates while the air
conditioner is not in operation.
The operation stopped suddenly.
(OPERATION lamp is on)
“ ” is displayed on the remote
controller, and the displayed contents flash
for several seconds when an operation button is pressed.
When three short “beep” sounds are issued
in the case of wireless remote controller.
COOL/HEAT cannot be changed over.
•
When the display shows “ ”
(CHANGEOVER UNDER CONTROL),
it shows that this is a slave remote
controller.
•
When the cool/heat changeover
remote control switch is installed
and the display shows “ ”
(CHANGEOVER UNDER CONTROL).
When a long “beep” sound is issued in
the case of wireless remote controller.
The liquid crystal of the remote controller shows “ ” immediately after the
power supply is turned on.
The compressor in the outdoor unit does
not stop after a short HEATING operation.
The inside of an outdoor unit is warm
when the unit has stopped
When the air conditioner has not been used
(the power has been off) for a long time.
Warm air exits the unit even though it is off.
You can feel hot air coming out of the unit.
■
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 out door 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 air conditioner is controlled by the central equipment.
•
Flashing of the displayed contents indicates that the remote controller is
invalid for control.
Refer to page 13.
•
This is because cool/heat changeover is controlled by the cool/heat
•
changeover remote control switch. Ask your Daikin dealer where the
remote control switch is installed.
This shows that the remote controller is in normal condition.
•
This continuoues for one minute.
This is to prevent oil and refrigerant from remaining in the compressor.
•
The unit will stop after 5 to 10 minutes.
This is because the crankcase heater is warming the compressor even
•
while the outdoor unit is stopped so that the compressor can start smoothly.
For protecting the mechanism, supply the power for 6 hours at first, then
•
operate the air conditioner.
Multiple units are operating on the same system, so if a unit in another
•
room is operating, some refrigerant will flow through the stopped units, too.
Call the service shop immediately.
WARNING
