6. White mist comes out of a unit.
<Indoor unit for air conditioning>
• When humidity is high during cooling oper-
ation.
If the interior of an indoor unit is extremely con-
taminated, the temperature distribution inside
a room becomes uneven. It is necessary to
clean the interior of the indoor unit. Ask your
Daikin dealer for details on cleaning the unit.
This operation requires a qualified service per-
son.
• Immediately after the cooling operation
stops and if the room temperature and
humidity are low.
This is because warm refrigerant gas flows
back into the indoor unit and generates steam.
<Indoor unit for air-conditioning, outdoor
unit>
• When the system is changed over to heat-
ing operation after defrost operation.
Moisture generated by defrost becomes steam
and is exhausted.
7. Noise of air-conditioners.
<Indoor unit for air-conditioning>
• A continuous low "shah" sound is heard
when the system is in cooling operation or
at a stop.
When the drain pump (optional accessories) is
in operation, this noise is heard.
• A low "sah", "choro-choro" sound is heard
while the indoor unit is stopped.
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.
<Outdoor unit, booster unit>
• When the tone of operating noise changes.
This noise is caused by the change of fre-
quency.
<Indoor unit for air-conditioning, outdoor
unit, booster unit>
• A continuous low hissing sound is heard
when the system is in cooling or defrost
operation.
This is the sound of refrigerant gas flowing
through both indoor and outdoor units.
• A hissing sound which is heard at the start
or immediately after stopping operation or
defrost operation.
This is the noise of refrigerant caused by flow
stop or flow change.
8. Dust comes out of the unit.
• When the unit is used after stopping for a
long time.
This is because dust has gotten into the unit.

9. The units can give off odours.
• During operation.
The unit can absorb the smell of rooms, furni-
ture, cigarettes, etc., and then emit it again.
10.The outdoor unit fan does not spin.
• During operation.
The speed of the fan is controlled in order to
optimize product operation.
11.The display shows "
• This is the case immediately after the main
power supply switch is turned on.
This means that the remote controller is in nor-
mal condition. This continues for one minute.
12.The compressor or fan in the outdoor unit
does not stop.
• This is to prevent oil and refrigerant from
remaining in the compressor. The unit will
stop after 5 to 10 minutes.
13.Hot air is emitted even though the unit is
stopped.
• Hot air can be felt when the unit is stopped.
Several different indoor units are being run on
the same system, so if another unit is running,
some refrigerant will still flow through the unit.
14.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 7.
15.The indoor fan may rotate while the unit
stops.
• The fan rotates even if the operation is
stopped with the remote controller.
As the system operates as an all-in-one air-
conditioner and refrigerator, the fan works to
prevent oil and refrigerant from accumulating
on the air conditioner during operation of the
showcase.
8-2 Check before Requesting Servicing.
