2. SAFETY CONSIDERATIONS
We recommend that you read this instruction manual carefully before use to gain full advantage of the
function of the air conditioner, and to avoid malfunction due to erroneous handling.
This air conditioner comes under the term
“appliances not accesible to the general public”.
• The precautions described below are WARNING and CAUTION. These are very important
precautions concerning safety. Be sure to
observe all of them without fail.
WARNING .. These are the matters with possi-
bilities leading to serious consequences such as death or serious
injury due to erroneous handling.
CAUTION ... These are the matters with possi-
bilities leading to injury or material
damage due to erroneous handling including probabilities leading to serious consequences in
some cases.
• After reading, keep this manual at a place
where any user can read at any time. Furthermore, make certain that this operation manual
is handed to a new user when he takes over
the operation.
WARNING
Avoid exposure of your body directly to the
cold air for a long time, or avoid excessive
exposure of your body to the cold air.
Otherwise, your physical condition may be deteriorated and/or your health may be ruined.
When the air conditioner is in abnormal conditions (smell of something burning, etc),
unplug the power cord from the outlet, and
contact the dealer where you purchased the
air conditioner.
Continued operation under such circumstances
may result in a failure, electric shock, and fire.
Ask your dealer for installation of the air conditioner.
Incomplete installation performed by yourself
may result in a failure, a water leakage, electric
shock, and fire.
Ask your dealer for improvement, repair, and
maintenance.
Incomplete improvement, repair, and maintenance may result in a failure, a water leakage,
electric shock, and fire.
Do not insert your finger, a stick, etc., into the
air inlet, outlet, and fan blades.
A fan in high-speed running may result in injury.
For refrigerant leakage, consult your dealer.
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 limiting concentration
even when it leaks. If the refrigerant leaks
exceeding the level of limiting concentration, an
oxygen deficiency accident may happen.
For installation of separately sold component parts, ask a specialist.
Be sure to use the separately sold component
parts designated by our company.

may result in a failure, a water leakage, electric
shock, and fire.
Ask your dealer to move and reinstall the air
conditioner.
Incomplete installation may result in a failure, a
water leakage, electric shock, and fire.
The refrigerant in the air conditioner is safe
and normally does not leak. If the refrigerant
leaks inside the room, the contact with a fire of
a burner, a heater or a cooker may result in a
harmful gas.
Do not use the air conditioner until when a service person confirms to finish repairing the portion where the refrigerant leaks.
CAUTION

9. NOT MALFUNCTION OF THE AIR CONDITIONER
The following symptoms do not indicate air conditioner malfunction
I. THE SYSTEM DOES NOT OPERATE
• The system does not restart immediately
after the ON/OFF button is pressed.
If the OPERATION lamp lights, the system is in
normal condition.
It does not restart immediately because a safety
device operates to prevent overload of the system. After 3 minutes, the system will turn on
again automatically.
• The system does not restart immediately
when TEMPERATURE SETTING button is
returned to the former position after pushing
the button.
If the OPERATION lamp lights, the system is in
normal condition.
It does not restart immediately because a safety
device operates to prevent overload of the system. After 3 minutes, the system will turn on
again automatically.
• The system does not start when the display
shows “” (UNDER CENTRALIZED
CONTROL) and it flashes for few seconds
after pressing an operation button.
This is because the system is under centralized
control. Flashes on the display indicates that the
system cannot be controlled by the remote controller.

II. The fan speed is different from the setting.
• Pressing the fan speed control button does
not change the fan speed.
When the room temperature reaches the set
temperature in heating mode, the outdoor unit
stops and the indoor unit switches to whisper
mode. This is to prevent the cool air from being
blown directly onto anyone in the room.
VI. DUST FROM THE UNITS
• Dust may blow out from the unit after starting
operation from long resting time.
Dust absorbed by the unit blows out.
VII.THE UNITS GIVE OFF ODORS
The unit absorbs the smell of rooms, furniture,
cigarettes, etc., and then emits them.
AIR BLOW DIRECTION IS NOT AS SPECIFIED.
III.
• Actual air blow direction is not as shown on
the remote controller.
• Automatic swing setting does not work.
Refer to “AIR FLOW DIRECTION ADJUST.”
IV. WHITE MIST COMES OUT OF A UNIT
• When humidity is high during cooling operation (In oily or dusty places)
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 unit. This operation requires a qualified service person.
• When the system is changed over to HEATING OPERATION after DEFROST OPERATION.
Moisture generated by DEFROST becomes
steam and exists.
V. NOISE OF AIR CONDITIONERS
• A ringing sound after the unit is started.
This sound is generated by the temperature regulator working.
It will quiet down after about a minute.
• A continuous flow “Shuh” sound is heard
when the systems is in COOLING or
DEFROST OPERATION.
This is the sound of refrigerant gas flowing
through both indoor and outdoor units.
• A “Shuh” sound which is heard 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.
This is the noise of refrigerant caused by flow
stop and flow change.
• A continuous flow “Shah” sound is heard
when the system is in COOLING OPERATION
or at a stop.
The noise is heard when the drain pump is in
operation.
• A “Pishi-pishi” squeaking sound is heard
when the system is in operation or after the
stop of operation.
Expansion and contraction of plastic parts
caused by temperature change makes this
noise.
VIII.THE LIQUID CRYSTAL OF THE REMOTE
CONTROLLER SHOW “”
• It happens immediately after the main power
supply switch is turned on.
This shows that the remote controller is in normal condition.
This continues temporary.
