Pick the right window. First, decide what
room(s) you want to cool. Then choose a
window that will allow the air-conditioned air
to flow freely and directly into the room(s)
you want cooled. Remember, it’s difficult to
move air around corners. If the inner sliding
window slides to the left, the unit will be
installed on the right. Remove window screen
if there is one. Choose a sliding window
that’s also near an electrical outlet. (Refer
to the ELECTRICAL REQUIREMENT page
for type of receptacle and wiring needed.)
Do not use an extension cord. The sliding
window in which you place your air condi-
tioner should have an opening of at least
15-l/2” wide and 21 -l/4” to 40.7/8” high
(see Figure 4). For installations up to 62.
l/4” high, a special kit (Part No. 977449)
is available. For windows as low as 20.7/16”,
you must install without filler frame and
remove top angle on unit, reinstalling 3 screws
into top of cabinet.
This model may also be installed in steel hinged
casement windows. The steel hinged case-
ment window must have an opening at 15-l/2”
wide and no more than 16-l/2” wide.

ing upon construction and depth of wall and

5/16” bolt, nut and washers (Items 4, 4A, 4B
and 4C).

Reinstall assembled shelf with two brackets
into the window opening. Adjust brackets
until shelf is firmly seated and sloping down
to outside. If you use a level, be sure you have
l/2 bubble of slope. Without a level, place the
translucent panel (Item 5) on shelf. The top
of long side of the panel will be 5/16” back
from the window line (see Figure 7).

If slope back is correct, tighten all nuts se-
curely. Install lower track seal (Item 4)
shown in Figure 8. This track seal has two
holes which line up with matching screw
holes in shelf.
