In case of problems, first turn off the air conditioner and disconnect from the source of electricity.
Symptom Solutions
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 controller is
not responding
• Is the remote controller out of effective distance to the indoor unit?
• Are there any obstructions between the controller and the signal
receptor?
• Is the battery exhausted?
Cooling/Heating
efficiency 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 filter 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 an unusual
smell blowing from the
outlet after operation
is started
• 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.
Please clean the air filter 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 flow 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
NOTE: Do not attempt to repair the unit by yourself. For repairs, contact the company that installed the
unit.
