INSTALL CASE LEVEL IN ALL DIRECTIONS
Note:
• Handle the case carefully.
• The cardboard stiffener inside the case, and the rear
protective panel must remain in place until the chassis
is installed to assure case rigidity and squareness.
• If a sub-base is to be used, it may be desirable to
assemble it to the case before securing the case in
the wall.
Case location
As a general rule the air conditioner should be
located in an outside wall to assure proper
distribution of conditioned air. It should be located
in a portion of the wall where there is no electrical
wiring or plumbing, and where there are no
obstructions immediately inside or outside.
STEP 1
Preparation of the wall
The wall case should be installed during construction
and lintels should be used to support the block above
the wall case. The case will not support the concrete
block or brick. The case is modular in height and
width:
Height — Fits 2 courses concrete block
— Fits 6 courses standard brick
— Fits 5 courses jumbo brick
Width — Fits approximately 3 stud spaces.
For existing construction, wall openings must be
made. Wall openings of the proper dimensions are
essential to avoid the necessity of fillers or additional
framing.
Note:
Use lintel to support brick, block, etc. above the air
conditioner case. (If directly under a window sill the
use of a lintel may not be necessary.)

STEP 2
Preparation of the case
Do not remove the cardboard stiffener inside the
case until the chassis is installed.
If field supplied case angles are to be used and must
be installed, proceed as follows:
1. Position the case angles around top and sides of
the case at the desired location (front to rear) with
angles facing toward rear (outside). Position the
case angles vertically on each side of the case to
provide a level installation.
2. Mark the case through the holes in the case angles.
3. Drill 5/32″diameter holes at marked locations
on the case and assemble the angles using only
10×1/2″ screws. Install the screws from the
outside of the case.
4. Do not drill any holes in bottom of the case.
