13.1 Symptoms that are NOT system
malfunctions
The following symptoms are NOT system malfunctions:
13.1.1 Symptom: The system does not operate
▪ The system does not start immediately after it is turned ON again.
If the operation lamp lights, the system is in normal condition. To
prevent overloading of the compressor motor, the system starts 5
minutes after it is turned ON again in case it was turned OFF just
before.
▪ The system does not start immediately after the power supply is
turned on. Wait one minute until the micro computer is prepared
for operation.
13.1.2 Symptom: The unit does not stop
immediately when operation is stopped
This is to prevent components from being damaged. The unit will
stop in a little while.
13.1.3 Symptom: Noise (Outdoor unit)
▪ A continuous low hissing sound is heard when the system is in
cooling 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. This is the noise of refrigerant caused by flow
stop or flow change.
▪ When the tone of operating noise changes. This noise is caused
by the change of frequency.
13.1.4 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.
13.1.5 Symptom: The outdoor unit fan does not
spin
During operation. The speed of the fan is controlled in order to
optimise product operation.
