tem. 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 sys-
tem. After 3 minutes, the system will turn on
again automatically.
• The system does not start when the display
shows "
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 con-
troller.
• The system does not start immediately after
the power supply is turned on.
Wait one minute until the micro computer is pre-
pared for operation.
• The outdoor unit is stopped
This is because the room temprerature has
reached the set temprerature. The indoor unit
switches to fan operation.
II. The display shows "
TRALIZED CONTROL) and the unit operates
in a mode different to what is shown on the
remote controller display.
When using a unit in a multi system, the opera-
tion condition of that unit is controlled by a micro
computer as described below, according to the
operation condition of other indoor units con-
nected to the system.
• If the operation mode does not match other
indoor units that are already running, the indoor
unit will assume the STANDBY state (the fan is
stopped and the air flow flap is positioned hori-
zontally).
If HEATING mode is set together with COOL-
ING, DRY or FAN mode, the above mentioned
condition will occur.
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 operating indoor units
exceeds the limit, the indoor unit will assume the
STANDBY state (FAN and AIR FLOW DIREC-
Operation Manual
" (UNDER CENTRALIZED
" (UNDER CEN-
TION will be left as set). (This only applies to
cooling only type.)
• If another indoor unit commences a HEATING
operation after this indoor unit is running in
COOLING mode, this indoor unit may switch to
DRY operation (fan on low, air flow flap set at hor-
izontal).
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
temperature in heating mode, the power supply
from the outdoor unit is stopped and the indoor
unit will operate on the low fan setting. (If using
the multi system, the fan will alternate between
off and low.)
This is to prevent the cool air from being blown
directly onto anyone in the room.
IV. AIR BLOW DIRECTION IS NOT AS SPECI-
FIED.
• Actual air blow direction is not as shown on
the remote contoller.
• Automatic swing 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 con-
taminated, 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 oper-
ation requires a qualified service person.
• When the system is changed over to HEAT-
ING OPERATION after DEFROST OPERA-
TION.
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 reg-
ulator 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 flowing sound "Shah"or a trick-
ling sound "Jyuru Jyuru"are heard when the
system is in COOLING OPERATION or at a
stop.
The noise is heard when the drain pump is in
operation.
