low Fan speed;
3. The air outlet of the air conditioner is
obstructed, for example, the shutter of
the cool air outlet or the ducts vents are
closed, or the filters are obstructed;
4. The ambient temperature is relatively low,
e.g. ≤78ºF (25.5ºC).
If the frosting or icing should occur, please
follow below instructions to clean up the frost
or ice.
How to clean up the frost or
ice?
Rotate the operating mode control knob to
the “HIGH FAN” mode position (as shown
above), and keep the air conditioner running
for half an hour. Then the frost and ice will be
melted and drop down of the evaporator coil,
and the air conditioner will be resumed.
WARING: During the defrosting or anti-
freezing process, the frost or ice will be
melted into water and might drop down from
the trim kit to the floor or furnitures. Make
sure you have prepared protections for your
floor or furnitures in advance, or you can use a
bucket to collect water.

How to prevent frosting or icing
in the air conditioner?
● Do not rotate the temperature control
knob to the “MAX COOL” position (as
shown above) at night to prevent being
frozen up.
● When the operating control mode knob is
in “COOL” mode position, always keep at
least 2 duct vents open to prevent being
frozen up.

frozen up when the ambient temperature is
relatively low, e.g. ≤78ºF (25.5ºC).
