CAUTION
Long-term air outlet at an angle of 30 degrees may cause condensation on the surface of the louver. It
is recommended to turn on the anti-condensation function through the remote controller to alleviate this
condition.
Operating Range
Use the unit in the following temperature and humidity ranges for safe and effective operation.
Cooling
Indoor
temperature 16~32°C
Indoor
humidity
≤80%
(When the humidity exceeds 80%, long-time operation of the indoor unit may cause dew
condensation on the surface of the indoor unit, generate mist-like cold air from the air
outlet or water dripping out of the unit.)
Heating
Indoor
temperature 15~30°C
NOTE
If it exceeds this operating range, safety devices may be put in action and the unit may not operate.

Symptoms That Are Not Faults
Normal Protection Of The Air Conditioner
During operation, the following phenomena are normal and do not require maintenance.
Protection
When the power switch is on, the air conditioner starts 3-5 minutes after it is turned ON
again in case it was turned off just before.
Anti-cold air
protection
(Heat
pump type)
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.
Defrosting
(Heat
pump type)
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.
