INSTALLATION
WIRING
The air conditioner is powered by plugging it into a
compatible wall outlet. The electrical outlet MUST
match the plug on the unit power cord. The unit name-
plate contains unit electrical data, unit ratings, and
identification numbers. Do not use a plug adapter or an
extension cord.
Check available power supply and resolve any wiring
problems before installing and operating the air condi-
tioner. If wiring is required, all wiring must comply
with all local and national electrical codes. All wiring
must be installed by a qualified electrician. If you have
any questions regarding the unit electrical data or wir-
ing, consult a qualified electrician before installation.
For your safety, this air conditioner is grounded
through the power cord plug when plugged into a
matching wall outlet.
WINDOW INSTALLATION
To install the room air conditioner in a window,
perform the following procedure.
1. Check contents of hardware kit. See Table 1. Make
sure all the items are in the plastic bag.
2. Determine which window will be used for installa-
tion. Make sure there is adequate clearance on the
inside and outside of the window. Ensure that the
power cord will reach the available socket without
an extension cord. A double-hung window type
must be used for the installation location.

3. Check that the window opening dimensions are
suitable for installation. The window must be
from 22 to 36-in. wide and the window must open
at least 141/4-in. high. It is recommended that the
window sill be at least 5/8-in. thick to support the
weight of the air conditioner. See Fig. 1.
NOTE: The top rail and the bottom sliding panels
at each side are offset to provide proper pitch
(5/16-in.) to the rear of the unit for condensate
draining. If the side panels are not used, this
pitch must still be maintained or condensate will
not drain properly.
4. For storm windows, remove the outer window
before installing the air conditioner. Remove any
screens that are in the window. If the storm win-
dow cannot be removed, read Storm Window
Applications section before proceeding.
5. Place the air conditioner on floor, table, bench, or
other flat working surface. Locate expanding side
panels. There are left and right panels.
6. Holding the expanding side panel in one hand,
gently pull the accordion center piece back to free
it from the top and bottom guide rails. See Fig. 2.
7. Slide the end of the accordion center of the side
panel into the slots on the unit cabinet. See Fig. 3
and 4. Slide the panel all the way down. Leave
enough space for the top and bottom guide rails to
fit into the unit cabinet.
8. Pull the top and bottom guide rails back around
the accordion center piece so that the accordion
center piece fits into the channel.

9. Slide the top and bottom guide rails into the slots
in the top and the bottom of the cabinet. See
Fig. 5. Slide the panel all the way in, flush to the
unit cabinet.
10. Repeat Steps 6-9 for the remaining side panel.
11. Center the unit in the window. The bottom of the
air conditioner frame should be against the
window sill. See Fig. 6. Lower the window sash
until it rests firmly against the top rail. Make
sure the top and bottom of the cabinet fit snugly
to the window opening.
12. Pull out the expanding side panels from the sides
of the cabinet. The panels should expand to cover
the entire width of the window. See Fig. 7. There
are two holes provided in the ends of each wing
panel which are used to secure the panels to the
window. With the wing panels expanded, mark
the drilling locations on the sides of the window
frame and sill (through the holes in the panels).
See Fig. 7.
13. Drill the holes marked in Step 12 with 1/8-in. drill
bit. With the side panels expanded, secure the
wing panels to sill with two 3/4-in. locking screws
provided (one each side). See Fig. 8. Secure side
panels to sash with two 1/2-in. locking screws (one
each side) provided. See Fig. 9.
Cabinet is not secure and may fall out of window. Be
careful with air conditioner until it is secured to the
window.

14. Install the sash safety bracket with a 3/4-in. screw
provided. Pre-drill the hole with 1/8-in. drill bit.
The sash safety bracket is installed on the upper
sash and is used to keep the window from open-
ing. See Fig. 10.
15. Cut the foam seal (provided) to fit the length of
the window. Insert the foam seal between the top
of the lower window sash and the window panes of
the upper window. See Fig. 11. Make sure there
is a firm fit to prevent air leakage between the
windows. This also prevents insects from entering
through the window.
16. Plug in the unit.
STORM WINDOW APPLICATIONS
If the storm window cannot be removed, a mounting
board (field-provided) may need to be added to the
window sash. The air conditioner needs to be pitched
downward to the back in order for condensate to drain
properly. The frame of the storm window (or any other
obstruction) must be at least 1/2in. lower than the win-
dow sill. If the storm window frame is less than 1/2in.
below the window sill, then a mounting board will
need to be added to raise the height of the window sill.
See Fig. 12. The board will need to be provided and cut
by the installer.
1. The length of wood should be a minimum of
11/2-in. wide and should run the length of the win-
dow. The thickness of the board is dependent on
the height of the storm window frame. The board
should raise the front of the air conditioner high
enough so that the unit will be pitched downward
at least 5/8-in. when the back of the unit is resting
on the storm window frame. See Fig. 12.
2. Cut the piece of wood to fit the window.
3. Install the wood piece on the window using 2 field-
provided nails or screws.
4. Drain holes or slots in storm window frame must
not be caulked or painted shut. Holes are needed
to drain rain water and condensate. Ensure that
trapped water can drain out.

REMOVING UNIT FROM WINDOW
The air conditioning unit may need to be removed for
the end of cooling season of for maintenance. Be sure
to save and store all parts for re-installation. To
remove the air-conditioning unit from the window,
perform the following procedure:
1. Turn the air conditioner off.
2. Unplug the power cord.
3. Remove the foam sash seal from between the
windows.
4. Remove sash safety bracket and screw.
5. Remove side panel screws (2 each side), that are
securing the side panels to the window.
6. Keeping a firm grip on the air conditioner, raise
the sash. Tilt the air conditioner back carefully to
allow any condensate in the air conditioner cabi-
net to drain. Remove the unit from the window.
7. Store all parts with the air conditioner.
After side panel screws are removed, cabinet is not
secure and may fall out of window. Be careful with
air conditioner until it is removed from the window.
