Through the Wall Installation Instructions—Optional.
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 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.

The case may be installed through the wall in both existing and new construction.
Read completely, then follow step-by-step.
Caulk all four sides on the outdoor side of the case to prevent moisture from getting through to the
interior wall. Use of flashing (drip rail) will further prevent water from dripping inside the wall and
down the outside of the building.
