When the unit is conducting cooling under low temperature, the surface of
indoor heat exchanger will be frosted; when the temperature of indoor heat
exchanger is decreased to below 0°C for a period of time, the outdoor unit will
stop operation.
When outdoor temperature is low and humidity is high, after operating for a period
of time, the heat exchanger of outdoor unit will be defrosted, which will lower
heating effect. At this time, the unit will start defrosting mode automatically.
1. During defrosting, there might be steam in outdoor unit. It is caused by quick
defrosting and is normal.
2. After defrosting, heating mode will be resumed.

ture in the following 3 kinds of status, the indoor fan will not be started to
prevent cold air from blowing (about 2 minutes):

When operating under heating mode or auto heating mode, shut down the unit
if compressor and indoor fan is working, the compressor and outdoor fan will
stop, air guide louver will be rotated to the horizontal location and indoor fan will
be off after operating for a period of time in low speed.
