rising and the indoor fan is fi xed at low speed.
When heating, the setting temperature decreases 1.8°F (1°C) (be higher
than 62.6°F (17°C)) every one hour, 2 hours later the setting temperature
stops rising and indoor fan is fi xed at low speed. (Anti-cold wind function

after power returns.
If there is a power failure while the unit is running, the compressor starts 3 minutes
after the unit restarts. If the unit was already off before the power failure, the unit
stands by.

In heating mode, the temperature can be set to as low as 8°C, preventing the indoor
area from freezing if unoccupied during severe cold weather.
6.4.14 Active Clean function
The Active Clean Technology washes away dust, mold, and grease that may cause
odors when it adheres to the heat exchanger by automatically freezing and then
rapidly thawing the frost. The internal wind wheel then keeps operating to blow-dry
the evaporator, thus preventing the growth of mold and keeping the inside clean.
When this function is turned on, the indoor unit display window appears "CL",
after 20 to 45 minutes, the unit will turn off automatically and cancel Active Clean
function.
