  6 Installation and use notice 
6.1 The inside should be higher than outside, to 
make sure that the water from evaporator will 
be easy to flow to the outside. and the water 
will be helpful to get more capacity and more 
EER. 
 
NOTE: Check that air conditioner is tilted back about 
H(tiled about 3°to 4°downward to the outside). After 
proper installation, condensate should not drain from 
the overflow drain hole during normal use, correct the 
slope otherwise. 
6.2 Cleaning filter 
The air filter should be checked at least once a month 
to see if cleaning is necessary.  Trapped particles in 
the filter can build up and cause an accumulation of 
frost on the cooling coils. 
•  Push the vent handle to  the Vent Closed position 
(where applicable). Open the front panel. 
•  Take the filter by the center and pull up and out. 
•  Wash the filter using liquid dishwashing detergent 
and warm water. Rinse filter thoroughly. Gently shake 
excess  water  from  the  filter.  Be  sure  the  filter  is 
thoroughly dry before replacing. Instead  of washing, 
you may vacuum the filter clean.
