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.

Freeze Protection:

If the unit is operating in COOL mode and in low ambient temperature, frost may form

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

indoor fan still run for 60s.

Operation Tips

2. In HEAT mode, if you turn off the unit, the compressor stops and the indoor fan still run for

10s.

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 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).
