The following symptoms do not indicate air condi-
tioner 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 sys-
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.
9. NOT MALFUNCTION OF THE AIR
CONDITIONER
• 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 con-
trol. Flashes on the display indicates that the system
cannot be controlled by the remote controller.
• 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.
II. 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.
• When the system is changed over to HEATING
OPERATION after DEFROST OPERATION.
Moisture generated by DEFROST becomes
steam and exists.
III.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 low “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.
IV.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.
