TROUBLESHOOTING & WARRANTY
TROUBLE POSSIBLE CAUSE
Air conditioner can not
operate at all.
• Has the power been shut down?
• Is the wiring loose?
• Is voltage too high or too low ?
(measured by professionals)
• Does it reach the set time for start up?
• Does the circuit protection device trip?
Remote control is not
available.
• Is the remote control out of effective dis-
tance to the indoor unit?
• Are there any obstructions between the
controller and the signal receptor?
• Is the battery exhausted?
Cooling (Heating) efciency
is not good.
• Is the setting temperature suitable?
• Is the air inlet or outlet obstructed?
• Is indoor fan speed set at low speed?
• Is there any heat source in your room?
• Is the air lter dirty?
Indoor unit does not operate
Immediately when the air
conditioner is restarted.
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.
There is unusual smell
blowing from the outlet
after operation is started.
The air conditioner itself does not have an
undesirable odor. If there is an odor, it may be
due to accumulation of the odor in the
environment. Please clean the air lter or
activate the cleaning function.
There is sound of running
water during the running
of air conditioner.
Sometimes the “hissing” sound of running
water can be heard. This is the sound of the
ow of the refrigerant, not a malfunction.
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.
During the cooling
operation, the indoor unit
outlet sometimes will blow out
mist.
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.
WARNING - Immediately stop all operations and turn off the power
supply, contact a Service center locally in following
situations.
• Shrill sound is heard or an unpleasant odor is emitted during the
operation.
• There is an abnormal heat in power supply cord and power plug.
• Accidentally pour impurities or water into the machine or the remote
control.
• Air switch or protection switch often breaks.
