pulling out the top of the inlet grille.
2. Using the tab, pull up slightly on the filter to release it and pull it down or up.
3. Clean the filter with warm, soapy water under 40°C (104°F).
4. Rinse and gently shake the water from the filter and let it dry before replacing it.
CAUTION: DO NOT operate the air conditioner without a filter because dirt and lint will
clog it and reduce performance.

Installation
1. To prevent vibration and noise, make sure
the unit is installed securely and firmly
2. Install the unit where the sunlight does not
shine directly on the unit.
3. The outside of the cabinet must extend
outward for at least 12" and there should
be no obstacles, such as a fence or wall,
within 20" from the back of the cabinet
because it will prevent heat radiation of the
condenser.
Restriction of outside air will greatly reduce
the cooling efficiency of the air conditioner.
CAUTION: All side louvers of the cabinet must remain exposed to the outside of the
structure.
4. Install the unit a little slanted so the back is slightly lower than the front(about 1/2").
This will force condensed water to flow to the outside.
5. Install the unit with the bottom about 30"~60" above the floor level.
Window Requirements
NOTE: All supporting parts should be secured to firm wood, masonry, or metal.
This unit is designed for installation in
standard double hung windows with actual
opening widths from 27" to 39".
The top and bottom window sash must open
sufficiently to allow a clear vertical opening of
16" from the bottom of the upper sash to the
window stool.
