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.

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.

9-12 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 normal 
condition. This continues for one minute.

9-13 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.

9-14 THE INSIDE OF AN OUTDOOR UNIT IS 

WARM EVEN WHEN THE UNIT HAS 
STOPPED

This is because the crankcase heater is warm-
ing the compressor so that the compressor 
can start smoothly.

9-15 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.

9-16 DOES NOT COOL VERY WELL

Program dry operation.

Program dry operation is designed to lower the 
room temperature as little as possible.
