Phenomenon
Not operate immediately when the air conditioner is restarted.
There's unusual smell blowing from the outlet after operation is started.
Sound of water flow can be heard during the operation.
In COOL mode, sometimes the mist emitted from the air outlet vent.
Waiting
Troubleshooting
●
Once the air conditioner is stopped, it will not operate in approximately 3 minutes to protect itself.
●
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. (Please contact with the authorized maintenance center.)
●
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.
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 awa y.
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.

4. The calculation method of additional refrigerant oil and refrigerant charging
amount after prolonging connection pipe
After the length of connection pipe is prolonged for 10m at the basis of
standard length, you should add 5ml
of refrigerant oil for each additional
5m of connection pipe.
The calculation method of additional refrigerant charging amount (on the
basis of liquid pipe):
(1) Additional refrigerant charging amount= prolonged length of liquid pipe × additional
refrigerant charging amount per meter
(2) When the length of connection pipe is above 5m, add refrigerant according
to the prolonged length of liquid pipe. The additional refrigerant charging
amount per meter is different according to the diameter of liquid pipe. See Sheet 2.
