A slight "click" sound
is heard at the of
start-up or shut-down
•
Due to temperature changes, panel and other parts will swell, causing the sound
of friction. →
This is normal, not a fault.
The indoor unit
makes abnormal
sound
•
The sound of fan or compressor relay switched on or off. When the defrosting is
star
ted or stop running, it will create sound.→
That is due to the refrigerant
flows to reverse direction. They are not malfunctions
.

There are water
drops over the
surface of the
indoor unit
•
When ambient humidity is high, water drops will be accumulated around the air
outlet or the panel, etc. →
This is a normal physics phenomenon.
•
Prolonged cooling run in open space produces water drops. →
Close the
doors and windows.
•
Too small opening angle of the louver blades may also result in water drops at
the air inlet. →
Increase the angle of the louver blades.
During the cooling
operation, the indoor
unit outlet sometimes
will blow out mist
•
When the indoor temperature and humidity are high, it happens sometimes. →
This is because the indoor air is cooled rapidly. After it runs for some time,
the indoor temperature and humidity will be reduced and the mist will
disappear.
•
Hear any harsh sound or smell any awful odor during running.
•
Abnormal heating of power cable and plug occurs.
•
The unit or remote controller has any impurity or water.
•
