The following events may occur during normal operation.
Compressor protection
This unit comes with a time delay function to help protect the compressor,please
allow 3 minutes for the compressor to restart upon turning on the unit.
Anti-cold air (Only for models with heating function)
The unit is designed not to blow cold air in HEAT mode when the indoor heat
exchanger is in one of the following three situations and the set temperature has
not been reached.
1. When heating has just starting.
2. Defrosting.
3. Low temperature heating.
Defrosting (Only for models with heating function)
Frost may be generated on the outdoor unit during heat cycle when outdoor
temperature is low and humidity is high resulting in lower heating efficiency
of the air conditioner. During this condition, air conditioner will stop heating
operation and start defrosting automatically.
The time of defrosting may vary from 0 to 8 minutes according to the outdoor
temperature and the amount of frost buildup on the outdoor unit.
The indoor or outdoor fan will stop running when defrosting (Only for models
with heating function).
The indoor unit will display "H1" code when defrosting, it's normal.
A white mist may generate due to a large temperature difference between
air inlet and air outlet in COOL mode in an indoor environment that has high
relative humidity.
A white mist may generate due to moisture generated from defrosting process
when the air conditioner restarts in HEAT mode operation after defrosting.
You may hear a low hissing sound when the compressor is running or has just
stopped running. This sound is the sound of the refrigerant flowing or coming to
stop.
You can also hear a craching sound when the compressor is running or has just
stopped running. This is caused by heat expansion and cold contraction of the
plastic parts in the unit when the temperature is changing.
A noise may be heard due to louver returning to its original position when power
is first turned on.
