Troubleshooting

●There might be power outages. → Wait until power is restored.
●Power plug may be loose out from the socket. →The plug in the plug tightly.
●Power switch fuse may blow. → Replace the fuse.
●The time for timing boot is yet to come. →Wait or cancel the timer settings.
The air conditioner does
not work.
The air conditioner can't run
after the immediate start-up
after it is shut down.
●If the air conditioner is turned on immediately after it is turned off, the protective delay
switch will delay the operation for 3 to 5 minutes.
The air conditioner stops
running after it starts up for a
while.
●May have reached the setting temperature. → It is a normal function phenomenon.
●May be at a defrosting state. → It will automatically restore and run again after defrosting.
●Shutdown Timer may be set. → If you continue to use, please turn it on again.
The air blows out of the
indoor unit, but the air is
not being cooled or heated.
●The air conditioner itself does not have undesirable odor.
If there is odor, it may be due to accumulation of the odor in the environment.
→Clean the air filter or activate the cleaning function.
The indoor unit blows out
odor.
There is sound of
running water during
operation of the system.
●When the air conditioner is started up or stopped the system can make a "hissing" sound
that might sound like running water.
→ This is the sound of the flow of the refrigerant and not a malfunction.
●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.
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 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. →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.
There are water drops
over the surface of the
indoor unit.
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 been exposed to excessive amounts of water.
●Circuit breaker continuously trips.
●

●
●Excessive accumulation of dust on filter, blocking the air inlet or outlet.
→Please clean the filter, remove the obstacles at the air inlet
●The louver blades are at an excessively angle limiting airflow.
→Please adjust the louvers to pointing straight.
●Poor cooling and heating effect caused by doors and windows opening, and unclosed
exhaust fan. →Please close the doors, windows, the exhaust fan, etc.
●Auxiliary heating function is not turned on while heating, which may lead to poor
heating effect. →Turn on the auxiliary heating function.
(only for models with auxiliary heating function)
●Mode setting is incorrect, and the temperature and wind speed settings are improper.
→Pleasere-select the mode, and set the appropriate temperature and wind speed.
Immediately stop all operations and cut off the power supply ,contact our Service center locally in following situations.
