• If the operating mode does not match that of
the other indoor units which are already run-
ning, the indoor unit goes into standby mode
(the fan stops and the air flow flaps become
horizontal).
The unit will go into the above mode if either cool-
ing, dry, or fan operation mode are set together
with heating mode.
NOTE
• Normally, the operation mode in the room where
the unit is first run is given priority, but the follow-
ing situations are exceptions, so please keep this
in mind.
a 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 sit-
uation, the air conditioner running in FAN Mode
will go on standby.
b With the Priority Room Setting active
Contact your Daikin dealer for the operation
that corresponds to your system.
• If the total capacity of all the indoor units run-
ning exceeds the limit, the indoor unit will go
into standby mode (fan and air flow direction
remain as set). (Only for cooling-only type.)
• If another indoor unit goes into heating mode
after cooling, the unit may go into dry mode
(fan operates whisper and the air flow flaps
become horizontal).
III.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 tem-
perature in heating mode, the power supply from
the outdoor unit stops and the indoor unit goes
into whisper mode (in a multi system, the fan goes
back and forth between stop and whisper).
This is to prevent the cool air from being blown
directly onto anyone in the room.
IV.AIR BLOW DIRECTION IS NOT AS SPECIFIED.
• Actual air blow direction is not as shown on
the remote controller.
• Automaticswing setting does not work.
Refer to "AIR FLOW DIRECTION ADJUST".
V.WHITE MIST COMES OUT OF A UNIT
• When humidity is high during cooling opera-
tion (In oily or dusty places)
If the inside of an indoor unit is extremely contam-
inated, 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.
Operation Manual
• When the system is changed over to HEATING
OPERATION after DEFROST OPERATION.
Moisture generated by DEFROST becomes
steam and exists.
VI.NOISE OF AIR CONDITIONERS
• A ringing sound after the unit is started.
This sound is generated by the temperature regu-
lator 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.
VII.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.
VIII.THE UNITS GIVE OFF ODORS
The unit absorbs the smell of rooms, furniture,
cigarettes, etc., and then emits them.
IX.THE LIQUID CRYSTAL OF THE REMOTE CON-
TROLLER 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.
X.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 6.
