Troubleshooting
USER'S MANUAL
•
When the air conditioner is started up or stopped, or the compressor
is started up or stopped during the running, sometimes the "hissing"
sound of running water can be heard. → This is the sound of the
flow of the refrigerant, not a malfunction.
There is sound
of running water
during the running,
of air conditioner.
•
The sound of fan or compressor relay switched on or off.
•
When the defrosting is started or stop running, it will create sound.
→That is due to the refrigerant flows to reverse direction. They are
not malfunctions.
•
Too much dust accumulation on 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
•
When ambient humidity is high, water drops will be accumulated
around the air outlet or the panel, etc. drops over the surface of the
indoor unit. →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.
•
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.
The indoor
unit makes
abnormal sound.
There are water
drops over the
surface of the
indoor unit.
During the cooling
operation, the
indoor unit outlet
sometimes will
blow out mist.
•
Due to temperature changes, panel and other parts will swell,
causing the sound of friction.
- This is normal, not a fault.
A slight "click"
sound is heard
at the of start-up
or shut-down
Immediately stop all operations and cut off the power supply , contact our
Service center locally in following situations.
•
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.
•
Air switch or leakage protection switch is often disconnected.
