Problem
Possible Cause
Solution
The wind blows out, but
the cooling/heating
effect is not good.
1.) Excessive
accumulation of dust
on filter, blocking at air
inlet and outlet, and the
excessively small angle
of the louver blades all
will affect the cooling and
heating effect.
1.) Please clean the filter,
remove the obstacles at
the air inlet and outlet
and regulate the angle of
the louver blades.
2.) Poor cooling and
heating effect caused
by doors and windows
opening, and unclosed
exhaust fan.
2.) Please close the
doors, windows, the
exhaust fan, etc.
3.) Auxiliary heating
function is not turned
on while heating, which
may lead to poor heating
effect.
3.) Turn on the auxiliary
heating function (only
for models with auxiliary
heating function).
4.) Mode setting is
incorrect, and the
temperature and wind
speed settings are not
appropriate.
4.) Please re-select
the mode, and set the
appropriate temperature
and wind speed.
The indoor unit blows out
odour.
The air conditioner
itself does not have
undesirable odour. If
there is odour, it may
be due to accumulation
of the odour in the
environment.
Clean the air filter or
activate the cleaning
function.
There is sound of running
water during the running
of air conditioner.
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.
A slight “click“ sound
is heard when the air
conditioner is switched on
or off.
Due to temperature
changes, panel and other
parts will swell, causing
the sound of friction.
This is normal, not a fault.
