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 in-
side 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.
