Through-the-Wall Installation Instructions—Optional
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.
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.
Remove the air conditioner from the case.
For specific instruction, refer to the Window
Installation Instructions.
Make certain that a wall receptacle is
available close to the hole location or make
arrangements to install a receptacle.
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.

FINISH THE WALL OPENING
Caulk all four sides on the outdoor side of
the case to prevent moisture from getting
through to the interior wall. Use of flashing
(drip rail) will further prevent water from
dripping inside the wall and down the
outside of the building.
Place the air conditioner into the case.
For specific instruction, refer to the Window
Installation Instructions.

IMPORTANT
(cont.)
Secure with 14 wood screws anchored at
least an inch into the wall support structure.
NOTE:
Drill pilot holes, if necessary, for
proper installation. If the frame is oversized,
use shims to prevent case distortion.
