Operation Tips

Cooling Operation
Principle:
Air conditioners absorb heat in the room and transmit it to the outdoor unit, so that the room
temperature is decreased. The cooling capacity will increase or decrease according to outdoor
ambient temperature.
Antifreezing Function:
If the unit is operating in COOL mode and in low ambient temperature, frost may be formed on
the heat exchanger. When indoor heat exchanger temperature decreases below zero, compres-
sor will stop operation to protect the unit.
Heating Operation
Principle:
Air conditioners absorb heat from outdoors and transmit it to the indoor unit, increasing room
temperature. The heating capacity will decrease at low ambient temperature.
Defrosting:
When outdoor temperature is low but humidity is high, frost may form on the outdoor unit dur-
ing extended operation, aff ecting heating effi ciency. The air conditioner may stop operation
during auto defrosting operation.
During auto defrosting, the fan motors of indoor unit and outdoor unit will stop.
During defrosting, the indoor indicator fl ashes and the outdoor unit may emit vapor.
This is not malfunction.
After defrosting is fi nished, the heating operation will recover automatically.
Anti-cold Air Function:
In HEAT mode, the indoor fan will not operate in order to prevent cold air blowing out
(within 2 minutes) if indoor heat exchanger doesn't reach a certain temperature under the
following three states:
1. Heating operation starts; 2. After Auto Defrosting is fi nished; 3.Heating at low temperature.
Rest Heat Blow
In the following situations, the indoor unit may still run for some time,
to blow out the rest heat of the indoor unit.
1. In HEAT mode, the temperature reaches the setting value, the compressor stops and the in-
door fan still run for 60s.
2. In HEAT mode, if you turn off the unit, the compressor stops and the indoor fan still run for 10s.
