Normal Phenomena that Are Not Air Conditioner Faults
The following phenomena are normal during operation of the air conditioner. They can be solved according to the
instructions below or do not need to be solved.
The Indoor Unit emits
white mist
The Indoor Unit blows
dust
The Indoor Unit emits
odor
Water drips on the air
conditioner surface
The air conditioner makes
low noise
Switching from cooling/
heating (not available for
cooling only units) mode
to fan only mode
In winter, the outdoor
temperature is low, and
heating effects may be
decreased
Mode conflict
No heating or cooling
options
1. In an environment where the indoor relative humidity is too high, when the Indoor Unit
runs in cooling mode, white mist may appear due to the humidity and the temperature
difference between the air inlet and outlet.
2. When the air conditioner is switched to heating mode after defrosting, the Indoor Unit
discharges the moisture generated from defrosting as steam.
When the air conditioner has not been used for a long time or is used for the first time, the
air filter should be cleaned. Otherwise, dust that has entered the Indoor Unit will be blown
out.
The Indoor Unit absorbs the odors of rooms, furniture or cigarettes, etc., and disperses the
odors during operation. It is advised to have the air conditioner cleaned and maintained
regularly by professional technicians.
When the indoor relative humidity is high, it is normal for condensation or slight water
blowing to occur on the surface of the air conditioner.
1. When the air conditioner is in "Auto", "Cool", "Dry", and "Heat" modes, it may emit a
low continuous "hissing" sound, which is caused by the refrigerant flowing between the
Indoor Unit and the Outdoor Unit.
2. A "hissing" sound may be heard for a short time after the air conditioner stops
operation or during "defrosting", which is caused when the refrigerant stops flowing or
changes its flow.
3. When the air conditioner is in Cool mode or Dry mode, a small and continuous rustling
sound can be heard, which is caused by the drain pump.
4. When the air conditioner starts or stops running, you may hear a squeaking sound
which is produced by the expansion or shrinkage of parts or surrounding aesthetic
materials due to temperature change. The sound will disappear when the air
conditioner is running normally.
When the Indoor Unit reaches the set temperature, the air conditioner controller
automatically stops the compressor operation and switches to the fan only mode. When the
room temperature rises (in cooling mode) or falls (in heating mode) to a certain level, the
compressor is restarted and cooling or heating operation is resumed.
1. During the heating operation of the heat pump type air conditioner, the air conditioner
absorbs heat from the outdoor air and releases it to heat the indoor air. This is the heat
pump heating principle of the air conditioner.
2. When the heat pump runs in heating mode, the Outdoor Unit blows out cold air,
causing the outdoor temperature to drop. When the outdoor temperature is extremely
low, the heating capability of the air conditioner drops gradually. You are advised to use
other heating devices for heating.
All Indoor Units in the same air conditioning system can only operate in the same mode, for
example, cooling, heating or others. If Indoor Units are in different modes, a conflict will
occur, making the system unable to start. Make sure that all the Indoor Units operate in the
same mode.
For the same air conditioning system, if Outdoor Unit operates in changeover mode, the
main wired controller allows users to select modes supported by the Indoor Units, while the
wired controller of a non-master Indoor Unit displays the icon of "No heating or cooling
options". In this case, the mode setting is unavailable, and other Indoor Units operate in the
same mode as the master Indoor Unit.
