Placement of Outer Case in Opening
Place outer case in opening, flush against one side of
opening. Use carpenter’s level and ensure case is level
from side to side and has a
3
/8-inch slope from front to back
(back of case must be
3
/8-inch lower than front to ensure
proper condensate drainage). If needed, use shims to level
case (from side to side) and to obtain proper back slope.
Front of case must project ¾-inch (minimum) beyond
inside wall in order to attach air conditioner front frame. If
framing indoor side of opening with wood molding (or other
decorative material), extend outer case ¾-inch beyond
molding.
When case is properly positioned in opening, use wood
shims to fill any gaps between case and finished opening,
especially in area where case will be secured to opening.
Take care not to warp or distort case when installing
shims. For condensate drainage, install drainage cup in
drain hole on baseplate of case.

Installation in Wall Thicker Than 9-inches
The side louvers in outer case provide ventilation to air
conditioner compressor and fan motor and must not be
blocked. When installing unit in a wall over 9-inches
thick, provisions must be made in wall opening to ensure
free air flow to the side louvers. This can be accomplished
by chamfering the vertical portions of the outside opening
as shown.
Ventilation louvers on top of case must not be obstructed.
Do not attempt to install unit in walls thicker than
11
2
/5-inches.
