13. Slide the empty cabinet into the wall opening and into
wooden frame. Approximately 21/2 in. of the cabinet
should be in the room. The rest of the cabinet should be
positioned through and outside the wall. See Fig. 25.
Maintain proper slope for condensate drain operation.
Bottom rail should be resting firmly on bottom board of
wooden frame.
14. Secure bottom rail to wood frame with two large wood
screws (1--in. long) using the two holes in the bottom of
the channel. See Fig. 26.
15. There are screw holes in the cabinet (4 each side, 4 top)
which are used to secure the cabinet to the wooden frame.
With the cabinet in its final position, drill holes in the
wooden frame using the screw holes in the cabinet as a
guide. After the holes have been drilled, secure the cabinet
to the wooden frame using field--supplied screws. See Fig.
27.
16. Caulk around wood frame and wall opening on outside
wall for a water--tight seal.

frame may be done on inside wall. Caulking provides an
air seal around the cabinet. Decorative wood trim may be
added to provide a more pleasing appearance.

Securing Cabinet to Frame
MASONRY CONSTRUCTION
The air conditioner is installed the same way as the Wall
Installation section with a few exceptions. Follow all local and
national building codes.
The cabinet can be secured to the masonry by using masonry nail
or masonry anchor screws.
Another installation technique would be to construct a frame of
2 x 4s and install the frame between the wall opening and the
cabinet. The frame must be securely anchored to the masonry
wall opening.
Use a lintel to support masonry above wall opening. Install
exterior cabinet support brackets.
