b)The accumulated operation time of the compressor is over than 50 minutes, the interval
time between defrosting process is 50 minutes(the accumulated time shall be recalculated if
power off or remote control off ), the continuous working time of the compressor is over 5
minutes.
Once the defrosting process starts, the compressor, the indoor fan and outdoor fan turn off,
and the four-way valve turns off after 30 seconds, and after another 15 seconds the
compressor turns on and starts the defrosting process.

The defrosting process ending condition
：（
The defrosting process will quit if one of the
below conditions to be satisfied
）
a) Outdoor coil ≥ 12
℃；
b) Defrosting process last for 12minutes
；
c) The defrosting process quits once change modes or air-conditioner turns off by remote
control.
After the defrosting process, the compressor turns off and the outdoor fan turns on; After 55
seconds, the four-way valve turns on; after another 5 seconds, the compressor turns on; the
air-conditioner resume the normal heating process, the indoor fan runs in the mode of
anti-cold wind.

When heating mode working normally, e.g. the compressor starts and the outdoor fan runs
and the four-way valve is electrified and the indoor fan starts, the electric heating starts if
satisfying the below conditions:
A
