Water leakage in the room.
The unit cannot deliver air.
Troubleshooting
Once the air conditioner is stopped, it will not operate for
approximately 3 minutes to protect itself
The unit has no peculiar smell by itself. If it has, that is due to
the smell accumulated in the ambient environment.
Solution: Clean the filter. If problem persists, professional
cleaning may be required. (Please contact an authorized
service centre).
The air conditioner is started, when it is running, or the unit is
stopped, sometimes there is swoosh or gurgle, the sound is
due to fluid flow. This is not a malfunction.
When the indoor temperature and humidity are very high, this
phenomenon would happen. This is caused by the room air
that is swiftly cooled down. After running for a while, indoor
temperature and humidity will fall down, the mist will desist.
This is caused by the deformation of plastic due to the
changes of temperature.
Is Temp. setting suitable?
Are inlet and outlet vents obstructed?
Is filter dirty?
Are the windows and doors closed? Fan speed set at low
speed?
Is there any heat sources in the room?
