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.

Finish the Wall Opening
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.
