When the power switch is on, if you start the system right after it is stopped, it is normal that
the Outdoor Unit does not operate for about four minutes as frequent compressor start/stop
is not supported.
In heating mode (including heating in automatic mode), when the indoor heat exchanger
does not reach a certain temperature, the indoor fan temporarily shuts off, or runs in Low
mode until the heat exchanger heats up to prevent the blowing of cold air.
When the outdoor temperature is low and the humidity is high, the Outdoor Unit's
heat exchanger may become frosted, which may reduce the heating capacity of the air
conditioner. If this occurs, the air conditioner will stop heating, enter automatic defrosting
mode, and return to heating mode after defrosting has been completed.
During the defrosting, the outdoor fan stops running and the indoor fan runs using the anti-
cold air protection function.
The defrosting operation time varies depending on the outdoor temperature and the degree
of frosting. It generally takes 2 to 10 minutes.
During the defrosting process, the Outdoor Unit may emit steam due to the rapid defrosting,
which is normal.
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.
During self-cleaning, there may be a slight clicking sound for about 10 minutes, indicating
that the Indoor Unit is freezing, which is normal.
