The case may be installed through-the-wall in
both existing and new construction.
Read completely, then follow step-by-step.
NOTE: Obtain all materials locally for mounting
the air conditioner through-the-wall.
1.
IMPORTANT
Through-the-wall installation is not appropriate
if any of the side or top louvers in the case will
be obstructed by the wall.
All side and top louvers in the case must
project on the outdoor side of the wall.
The room side of the case must project
into the room far enough to maximize the
balance of the unit.
The case must be installed level from side-to-
side and with a slight tilt from front to rear. Use
a level; no more than a 1/2 bubble will be the
correct case slant to the outside.
Lintel angle is required to support bricks or
blocks above opening.
Flashing is required and should extend the
length of the opening to ensure no inside
cavity leakage occurs.
A. Remove the air conditioner from the case. For
specific instruction, refer to the Window Installation
Instructions.
B. Make certain that a wall receptacle is available
close to the hole location or make arrangements to
install a receptacle.
C. Place the case in the wall opening and
place wood support strips between the case
bottom and the flashing on both sides of the
bottom rail. They should be the same height as
the bottom rail and the same length as the wall
opening.

to prevent moisture from getting through to the

down the outside of the building.
B. Place the air conditioner into the case.
For specific instruction, refer to the Window
Installation Instructions.
