Operation Tips
Cooling Operation
16
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,
compressor will stop operation to protect the unit.
*
*
*
*
*
Principle:
Defrosting:
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.
When outdoor temperature is low but humidity is high, frost may form on the outdoor unit
during extended operation, affecting heating efficiency. 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 flashes and the outdoor unit may emit vapor.
This is not malfunction.
After defrosting is finished, 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 finished; 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
2. In HEAT mode, if you turn off the unit, the compressor stops and the indoor fan still run for 10s

Operation Tips
Tips for energy saving:
*Do not overcool or overheat.
Setting temperature at a moderate level helps energy saving.
*Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors is favorable for cooling (heating).
*Clean air filters once per two weeks.
Clogged air filters lead to inefficient operation and energy waste.
Tip for relative humidity:
Condensate water is likely to form at the air outlet if cooling or drying for a long time
when the relative humidity is more than 80% (with doors and windows open).
The climate type of this unit is according to the nameplate.
