9-4 FAN OPERATION IS POSSIBLE, BUT 

COOLING AND HEATING DO NOT 
WORK

• Immediately after the power is turned on.

The micro computer is getting ready to operate.
Wait 10 minutes.

9-5 THE FAN STRENGTH DOES NOT COR-

RESPOND TO THE SETTING

• The fan strength does no change even if the 

fan strength adjustment button in pressed.

During heating operation, when the room temper-
ature reaches the set temperature, the outdoor 
unit goes off and the indoor unit changes to whis-
per fan strength.
This is to prevent cold air blowing directly on occu-
pants of the room.
The fan strength will not change even if the button 
is changed, when another indoor unit is in heating 
operation.

9-6 THE FAN DIRECTION DOES NOT COR-

RESPOND TO THE SETTING

• The fan direction does not correspond to the 

remote control display.
The fan direction does not swing.

This is because the unit is being controlled by the 
micro computer. Refer to “Adjusting the air flow 
direction”.

9-7 WHITE MIST COMES OUT OF A UNIT

Indoor unit

• When humidity is high during cooling operation.

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 opera-
tion requires a qualified service person.

• 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, outdoor unit

• When the system is changed over to heating 

operation after defrost operation.

Moisture generated by defrost becomes steam 
and is exhausted.

9-8 NOISE OF AIR CONDITIONERS 

Indoor unit

• A “zeen” sound is heard immediately after the 

power supply is turned on.

The electronic expansion valve inside an indoor 
unit starts working and makes the noise. Its vol-
ume will reduce in about one minute.

• 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 “pishi-pishi” squeaking sound is heard when 

the system stops after heating operation.

Expansion and contraction of plastic parts caused 
by temperature change make this noise.

• 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 refriger-
ant from remaining in the system, a small amount 
of refrigerant is kept flowing.

Outdoor unit

• When the tone of operating noise changes.

This noise is caused by the change of frequency.

Indoor unit, outdoor unit

• A continuous low hissing sound is heard 

when the system is in cooling or defrost oper-
ation.

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.

9-9 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.

9-10 THE UNITS CAN GIVE OFF ODOURS

• During operation.

The unit can absorb the smell of rooms, furniture, 
cigarettes, etc., and then emit it again.

9-11 THE OUTDOOR UNIT FAN DOES NOT 

SPIN

• During operation.

The speed of the fan is controlled in order to opti-
mize product operation.
