into space between upper and lower sashes
(Fig.18).
2. Attach right angle safety lock (Fig. 19).
4. Attach the top angle to window frame: Use a
3/32" drill bit to drill one hole through the hole
in the middle of top angle into the window frame,
and drive one 3/ 4 " (or 1/ 2 '' ) HEX-HEAD locking
screw through hole in the middle of top angle

1. Lift air conditioner and carefully slide into
cabinet leaving 6 inches protruding.
2. DO NOT push on controls or nned coils.
3. Be sure chassis is rmly seated towards rear of
cabinet.
4. Installation of front is the reverse of removal
outlined in Section 1.
In order to minimize air leaks and ensure optimal
insulation, it is necessary to install the included R1
hardware to the side curtain. Follow the
instructions below.
Step 1. After the unit is installed to the window,
measure the inner width of the side curtain as
shown (Fig.20).
Step 2. Remark a line on the provided R1
insulation panel according to a length 1/8 "
(3mm) less than the measured width in step 1,
then cut the R1 insulation panel along the line
(Fig. 12).
Step 3. Slide the R1 insulation panel into the
side curtain, the side with pattern should facing
the indoor(Fig. 22).
In order to minimize air leaks between the room
air conditoner and the window opening, trim the
weather stripping with a proper length, peel o
the protective backing and plug any gaps if
needed (Fig.23).
Step 4. Repeat on the other side.

B. Thru-The-Wall Installation
NOTE: Consult local building codes prior to
installation or a qualied carpenter.
NOTE: If wall thickness is 8-1/2 " or more, add
aluminum ashing over bottom of frame opening
to assure no water can enter area between inner
and outer wall.
The air conditioner has a slide-out chassis, so
that it can be installed through an outside wall
as specied below:
Max. Wall thickness: 12" or 10"
IMPORTANT: Side louvers must never be blocked.
NOTE: All parts needed for Thru-The-Wall
Installation are provided, except a wood frame,
shims, and 10 wood screws(#10-1" long minimum).
Select a wall surface that:
1. does not support major structural loads such
as the frame construction at ends of windows,
and under truss-bearing points, etc.
2. does not have plumbing or wiring inside.
3. is near existing electrical outlets or where
another outlet can be installed.
4.is not blocked to the area to be cooled.
5. allows unblocked airow from rear sides and
end(outside) of installed air conditioner.
1. Prepare wall in frame construction (including
brick and stucco veneer). Working from inside
the room, nd wall stud nearest the center of
area where air conditioner will be installed (by
sounding wall or by magnetically nding nails).
2. Cut or knock out a hole on each side of center
stud.
3. Measure between inside edges of every other
stud as shown in Fig.1.
4. Build a wooden frame with the INSIDE dimensions
of your model listed above. (Remember to measure
twice). Frame depth should be the same as wall
thickness. Fill in the space from the opening to the
studs with wood spacers,as shown.
5. Nail frame to spacers to spacers with front ush
with drywall.
Carefully measure and cut an opening with the
following dimensions depending on your model.
See Fig.1 and Fig.2.
WIDTH " X"= inside model width plus twice the
thickness of framing material used.
HEIGHT '' Y " = inside model height plus twice the
thickness of framing material used.
