Split system air conditioners

13.1.7
Symptom: 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 one minute.
▪ A continuous low "shah" sound is heard when the system is in
cooling operation or at a stop. When the drain pump 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.
13.1.8
Symptom: Noise of air conditioners
(Indoor unit, outdoor 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.
13.1.9
Symptom: Noise of air conditioners
(Outdoor unit)
When the tone of operating noise changes. This noise is caused by
the change of frequency.
13.1.10 Symptom: Dust comes out of the unit
When the unit is used for the first time in a long time. This is
because dust has gotten into the unit.
13.1.11 Symptom: The units can give off odours
The unit can absorb the smell of rooms, furniture, cigarettes, etc.,
and then emit it again.
13.1.12 Symptom: The outdoor unit fan does not
spin
During operation. The speed of the fan is controlled in order to
optimise product operation.
13.1.13 Symptom: The display shows "88"
This is the case immediately after the main power supply switch is
turned on and means that the user interface is in normal condition.
This continues for 1 minute.
13.1.14 Symptom: The compressor in the outdoor
unit does not stop after a short heating
operation
This is to prevent refrigerant from remaining in the compressor. The
unit will stop after 5 to 10 minutes.
