WALL INSTALLATION
To install the room air conditioner in the wall, perform
the following procedure:
1. Remove air conditioner from shipping box. Do not
install window installation parts.
2. Determine the location for air conditioner. Make
sure there is adequate clearance on the inside and
outside of the wall. Ensure that the power cord
will reach the available socket without an exten-
sion cord. Air conditioner can be installed in walls
up to 7 in. thick. Side louvers must never be
blocked. Select a wall surface that:
•does not support major structural loads such as
the frame construction at ends of windows and
under truss-bearing points
•does not have plumbing or wiring routed inside
•is near existing electric al outlets or near where
a new outlet can be installed
•faces the area to be cooled and is not blocked by
obstructions
•allows unblocked airflow from rear (outside) of
installed air conditioner
3. The following parts will need to be provided by the
installer:
•wood frame
•wood shims
•wood screws (no. 10, 1-in. long)
4. Working from the inside of the room, find a wall
stud nearest the center of the area where the air
conditioner will be installed. This can be deter-
mined by sounding walls or using a stud finder.
5. Cut or knock out a hole on each side of the center
stud. See Fig. 19.
6. Measure between the inside edges of every other
stud as shown in Fig. 19.
7. Follow all local building codes when building and
installing frame. Build a wooden frame that will
be placed around the unit in the wall. The frame
will reinforce the hole in the wall where the air
conditioner is installed and is used to secure the
air conditioner to the wall. The frame should have
an inner dimension of 20.5-in. width by 14.8-in.
height for CA1016KR air conditioners or 22.8-in.
width by 15.7-in. height for CA1216KR air condi-
tioners to ensure that the air conditioner will fit
inside the frame. See Fig. 20. The depth of the
frame should approximately match the depth of
the wall. The thickness of the frame will need to
be added to the dimensions to determine the size
of the hole in the wall.
For example, if using
3
/
4
-in. thick wood for the
frame, the hole would need to be:
20
1
/
2
+
3
/
4
+
3
/
4
= 22-in. wide.
8. After the frame has been constructed, check to
make sure that the air conditioner fits correctly
inside it. If the frame is too tight or too loose,
adjust the size or re-construct.
9. Measure the outer dimensions of the frame and
use those dimensions to cut the hole in the wall.
Make sure the hole is level or condensate will not
drain properly.
10. Install wooden frame into hole in wall. Make sure
frame is properly secured. Fill in the space
between the frame and the studs with wood shims
(spacers). Nails spacers to studs. If required, pro-
vide studs around entire frame to reinforce stabil-
ity of wall. See Fig. 21.
IMPORTANT: Read entire instructions before cut-
ting hole in wall.
IMPORTANT: Be sure to measure air conditioner
to check size before constructing frame.
IMPORTANT: If thickness of the wall covers top
and side vents of the air conditioner when it is
installed, the outer portion of the wall opening
must be widened. The top and side vents must be
clear and uncovered.
