Troubleshooting
CAUTION
Don't attempt to repair the air conditioner by yourself.It may cause the electric shock or
fire. Please check the following items before asking for repair.It can save your time and
money.
Phenomenon
Troubleshooting
Once the air conditioner is stopped, it will not
operate in approximately 3 minutes to protect
itself.
Not operate immediately when
the air conditioner is restarted.
There's unusual smell blowing
from the outlet after operation
is started.
The unit has no peculiar smell by itself. If has,
that is due to the smell accumulated in the
ambient.
Solution method: Cleaning the filter.
If problem still has, so need to clean air conditioner.
Sound of water flow can be heard
during the operation.
The air conditioner is started, when it is running the
compressor started or stopped running, or the unit
is stopped, sometimes there is swoosh or gurgle,
the sound is due to refrigerant flowing they are not
malfunctions.
In COOL mode, sometimes the mist emitted
from the air outlet vent.
When the indoor
temperature and humidity are
very high, this phenomenon would happen. This
is caused by the room air is swiftly cooled down.
After running for a while, indoor temperature and
humidity will fall down, the mist will die away.
Creaking noise can be heard when start or stop
the unit.
This is caused by the deformation of plastic due to
the changes of temperature.

Troubleshooting
The unit can not run
Has the power been shut down?
Is the circuit protection device tripped off or
not?
Breaking off
Is voltage higher or lower?
(Tested by professionals)
Is the Timer correctly used?
Cooling (Heating) efficiency is not good.
Is Temp. setting suitable?
Were inlet and outlet vents obstructed?
Is filter dirty?
Are the windows and doors clothed?
Did Fan speed set at low speed?
Is there any heat sources in the room?
Wireless remote control is not available
The unit is interfered by abnormal or frequent
functions switchover occasionally the controller cannot operate. At this time, you need to
pull out of the plug, and reinsert it.
If water leakage in the room
The air humidity is on the high side.
Condensing water over flowed.
The connection position of indoor unit drainage
pipe is loosed.
If water leakage in outdoor unit
Noise from indoor unit emitted
The sound of fan or compressor relay is
switching on or off.
When the defrosting is started or stop running,
it will sound. That is due to the refrigerant flowed
to the reversed direction.

When the unit is running in COOL mode, the
pipe and connection of pipe would be
condensed due to the water cooled down.
During heating or defrosting operation, the
melted water will blow out.
● In heating procedure, when the heat exchanger
temperature of indoor unit is low, it stops blowing
in order to avoid blowing cool air (within 90 s).
