Cleaning the Air Filter 

 The air filter is removable for easy cleaning. A clean 
filter helps remove dust, lint, and other particles from 
the air and is important for best cooling and 
operating efficiency. Check the filter every 2 weeks 
to see whether it needs cleaning. 

NOTE:

 Do not operate the air conditioner without the 

filter in place. 
1.  Turn off the air conditioner. 
2.  Remove air filter by sliding filter out from either 

side of unit.
