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.
IMPORTANT
Through-the-wall installation is not
appropriate if any of the side louvers in the
case will be obstructed by the wall.
All side louvers in the case must project on
the outdoor side of the wall.
The room side of the case must project into
the room at least 1
3
⁄4″ from the finished wall.
The case must be installed level from side-
to-side and with a slight tilt from front to
rear. Use a level; about a 1/2 bubble will be
the correct case slant to the outside.
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
secure with 12 1″ long #10 wood screws.
NOTE: Drill pilot holes, if necessary, for
proper installation. If the frame is oversized,
use shims to prevent case distortion.
