Defrosting & Anti-Freezing Instructions
Frost or even ice formed on part of or the entire evaporator
coil is not unusual under certain conditions or below combined
conditions:
1. The air conditioner is operating with very cold temperature
setting;
2. The air conditioner is operating at very 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. ≤78°F
(25.5°C).
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.
