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 IDU emits white mist
1. In an environment where the indoor relative humidity is too high, when the IDU 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 IDU discharges the moisture
generated from defrosting as steam.
The IDU blows dust
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 IDU will be blown out.
The IDU emits odor
The IDU 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.
Water drips on the air conditioner surface
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.
"Self-cleaning" sound of icing
During self-cleaning, there may be a slight clicking sound for about 10 minutes, indicating that the IDU is
freezing, which is normal.
The air conditioner makes low noise
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 IDU and the ODU.
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.
Switching from cooling/heating (not available for cooling only units) mode to fan only mode
When the IDU reaches the set temperature, the air conditioner compressor automatically stops 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.
In winter, the outdoor temperature is low, and heating effects may be decreased
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 ODU 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.
No heating or cooling options
All IDUs in the same air conditioning system can only operate in the same mode, for example, cooling, heating, or
others. Conflict may occur if IDUs are set to different modes. Only the IDU that is first started up can determine the
operating mode, and those started after it can only follow the operating mode of the first IDU. To change the
operating mode, you need to turn off all the IDUs. The operating mode of all IDUs must be the same.
