White mist comes out of the unit

 

„

Indoor unit

When humidity is high during cooling operation.

 

If the interior of indoor unit is extremely contaminated, 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 quali

fi

 ed service person.

Immediately after the cooling operation stops and if the room temperature and humidity are low.

 

This is because warm refrigerant gas 

fl

 ows back into the indoor unit and generates steam.

When the system is changed over to heating operation after defrost operation.

 

Moisture generated by defrost becomes steam and is exhausted.

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 volume will reduce in about 1 minute.

A continuous low “shah” sound is heard when the system is in cooling operation or at a stop.

 

When the drain pump (an optional accessory) 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 refrigerant from remaining in the system, a small amount of 
refrigerant is kept 

fl

 owing.

Outside unit

When the tone of operating noise changes.

 

This noise is caused by the change of frequency.

Indoor unit, outside unit

This is the sound of refrigerant gas 

fl

 owing through both indoor and outside 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 

fl

 ow stop or 

fl

 ow change.

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.

The units can give off odours

 

„

During operation.

 

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

The outside unit fan does not rotate

 

„

During operation.

 

The speed of the fan is controlled in order to optimize product operation.

The compressor or fan in the outside 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.

 

The inside of outside unit is warm even when the unit has stopped

 

„

This is because the crankcase heater is warming the compressor so that the compressor can start smoothly.
