Troubleshooting
The indoor unit makes
abnormal sound.
•
The sound of fan or compressor relay switched on or off.
•
When the defrosting is started or stop running, it will sound.
→
That is due to the refrigerant flowed to reverse direction.
They are not malfunctions.
•
Too much dust accumulation in the air filter of the indoor
unit may result in fluctuation of the sound.
→
Clean the air
filters in time.
•
Too much air noise when "Strong wind" is turned on.
→
This
is normal, if feeling uncomfortable, please deactivate the
"Strong wind" function.
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.
