THRU-THE-WALL INSTALLATION INSTRUCTIONS
STEP 1:
SELECT WALL LOCATION
The air conditioner has a slide-out chassis so that it can be
installed through an outside wall as specified below:
Max. Wall Thickness: 12″ or 10″
IMPORTANT: Side louvers must never be blocked.
NOTE: All parts needed for Thru-The-Wall Installation are
provided except a wood frame, shims, and 10 wood screws
(#10-1 long minimum).
Select a wall surface that:
• Does not support major structural loads such as the frame
construction at ends of windows, under truss-bearing
points, etc.
• Does not have plumbing or wiring inside.
• Is near existing electrical outlets, or where another outlet
can be installed.
• Faces (and is not blocked) the area to be cooled.
• Allows unblocked airflow from rear sides and end (outside)
of installed air conditioner.
STEP 2:
PREPARE WALL
1. Prepare wall in frame construction (including brick and
stucco veneer). Working from inside the room, find wall
stud nearest the center of area where air conditioner will be
installed (by sounding wall, or by magnetically finding nails.)
2. Cut or knock out a hole on each side of center stud.
3. Measure between inside edges of every other stud as
shown in Fig. 1.
NOTE: Carefully measure and cut an opening with the
following dimensions, depending on your model. (See Fig. 1
and 2.)
WIDTH “X” = inside model width plus twice the thickness of
framing material used.
HEIGHT “Y” = inside model height plus twice the thickness of
framing material used.
Inside Frame Height 18 7/8″ (47.9 cm) or 18″ (45.7 cm)
Inside Frame Width: 26 3/4″ (67.9 cm) or 23 7/8″ (60.6 cm)
4. Build wooden frame with the INSIDE dimensions of
your model listed above. (Be sure to measure twice for
accuracy.) Frame depth should be the same as wall
thickness. Fill in the space from the opening to the studs
with wood spacers. (See Fig. 3.)
5. Nail frame spacers, with front flush with drywall.
