3. Install the finished frame in the wall
opening square and level, nail or
screw it securely to the wall and
place the cabinet into the framed
wall opening.
4. Make sure cabinet projects into the
roomside of the wall 1 1/4” at the
top and 1 1/2” at the bottom to
ensure proper tilt and access to the
anti-theft screw, then fasten cabinet
to the frame by drilling twelve (12) 1”
wood screws (not supplied) through
the cabinet and into the frame. (Fig.
1 &2)
If installation is made in a building
with brick veneer construction, a
steel angle lintel must be used to
support the bricks above the
cabinet.(Fig.3)
5. Install a 3/4” X 1 1/2” wood filler
strip between the bottom bar and
the interior, caulk both top and
bottom of this strip. After cabinet is
installed caulk all openings, inside
and outside between finish frame
and cabinet to prevent moisture
from getting to the interior of the
wall. Use of flashing (driprail) will
further prevent water from dripping
inside the wall.
6. Install chassis into cabinet.
Through-the-wall Installation
This air conditioner is designed as a
slide-out type chassis, making it possible
to install it through-the-wall in both
existing and new construction. We
recommend that this type of installation
be performed with professional
assistance.
• IMPORTANT: This appliance must be
installed according to all applicable
electrical and building codes and
ordinances.
• It is recommended that you have help
to install your unit and that you use
proper lifting technique to avoid
personal injury.
• It is important that you inspect the
condition of the wall where the air
conditioner will be installed.
• Be sure the wall can support the
weight of the unit.
• All cabinet louvers MUST BE on the
outdoor side of the wall. DO NOT
BLOCK SIDE LOUVERS.
• The cabinet must be installed level
from side-to-side and with a downward
tilt from inside to outside.
1. First remove the Decorative front
panel and chassis from the cabinet,
then remove top bar from the
cabinet.
2. Determine the size of the opening
for a wood frame by adding 1/8” to
the width and height of the cabinet.
Measure height from top of cabinet
to bottom of bar. Add this
measurement to the thickness of
wood used to build the frame. This
will determine the size of wall
opening needed. Minimum 1” thick
lumber is recommended when
building the frame. When
determining finish frame thickness,
be sure not to cover side louvers on
the cabinet.
Do not obstruct the air intake area
of your air conditioner, as this could
cause overheating, thus activating
the units security switch and
shutting off the unit. Do not block
aiflow inside with blinds, curtains,
or furniture. Do not block airflow
outside with shrubs, enclosures, or
other buildings.
Do not drill a hole in the bottom
pan. Unit is designed to operate
with approximately 1/2” of water
in bottom pan.
Installing the Chassis into the
Cabinet

cabinet.
2. Replace the two antitheft screws
at the bottom front sides of

both sides of the decorative
front. Make sure the power cord
aligns with the power cord slot
on the bottom of the decorative
front. Make sure the decorative
front is secure before
reconnecting the plug and
operating the unit.
4. Cut plastic foam seal to width of
window and install between
upper and lower window sash.
5. Use latex or silicone sealant (not
