6.Next you must customize the Plastic Extender Panels so that

the Window Sealing Frame will fit securely in your window. Each
Plastic Extender Panel is divided into segments stamped with
measurements between 26 to 38 inches. These measurements
represent the total inside measurement, in inches, of various
sized windows. See Figure 7.
CAUTION: Once you have removed segments from the Plastic
Extender Panels, the frame will only fit in windows equal to or
less than the width you have selected.

7.Use the black marker to mark the number on each Plastic

Extender Panel that is closest to (but not greater than), the
measurement you recorded in Step 1. For example, if your win-
dow is 33 inches wide, mark the number 32. See Figure 8.

8.Snap off each segment of the front of the Plastic Extender Panel

with a higher number than you
marked. If you marked 32 in
step 8, you only will remove the
segments for 38, 36 and 34 and
three segments from the back of
the Plastic Extender Panel. Use
a forward and backward motion
to remove the excess sections
along the scored indications.
See Figure 9. Remove the same
number of segments from the
back of the Plastic Extender
Panel.

9.Repeat this process on the other

Plastic Extender Panel.

10.Install the Foam Insulation

Blocks into the Plastic Extender
Panels. Note that the Foam
Insulation Blocks are divided into
vertical segments of various
widths. The foam is installed
with these segments oriented
vertically. See Figure 10A. Insert
a Foam Insulation Block into the
right Plastic Extender Panel. For
proper fit, the foam should be
only slightly wider than the
Plastic Extender Panel. If the
foam is the exact size, rotate the
foam block to utilize the half-size
foam block on the opposite
side. Reinstall the foam into the
Plastic Extender Panel. See
Figure 10B.

When using electrical appliances, basic safety precautions should
always be followed to reduce the risk of fire, electric shock, and
injury to persons, including the following:
•  Read all instructions before using the appliance.
•  To avoid fire or shock hazard, plug the product directly into a

120V AC electrical outlet.

•  Remove any plastic bags before use.
•  Keep the cord out of heavy traffic areas. To avoid fire hazard,

NEVER put the cord under rugs, near heat registers, radiators,
stoves, or heaters.

•  To protect against electrical hazards, DO NOT immerse in

water or other liquids. Do not use near water.

•  Close supervision is necessary when any appliance is used by

or near children, or disabled persons.

•  Avoid contact with moving parts.
•  Always unplug the product before moving it, opening the grill,

changing the filters, cleaning, or whenever the product is not in
use. Be sure to pull by the plug and not the cord.

•  NEVER drop or insert any object into any openings other than

instructed in this manual.

•  DO NOT operate any appliance with a damaged cord or plug,

if motor fan fails to rotate, after the appliance malfunctions, or
if it has been dropped or damaged in any manner. Return
appliance to manufacturer for examination, electrical or
mechanical adjustment, or repair.

•  Use appliance only for intended household use as described in

this manual. Any other use not recommended by the manufacturer
may cause fire, electric shock, or injury to persons. The use of
attachments not recommended or sold by JCS/THG,LLC may
cause hazards.

•  NEVER block the air openings, grills/outlets or place objects

that would cause blockage of the air intake/exhaust openings.

•  Keep unit away from heated surfaces and open flames.
•  DO NOT attempt to repair or adjust any electrical or mechani-

cal functions on this unit. Doing so will void the warranty on
serviceable parts. All servicing should be performed by 
qualified personnel only.

•  WARNING: To reduce the risk of fire or electric shock, DO NOT

use this product with any solid-state speed control device.

•  Install horizontally only in a double hung window as described

in this manual.

Outside filters should be serviced by first sliding the unit out of
the Window Sealing Frame and into the room.

•  DO NOT use unit as a shelf or place anything on top of unit.

THIS PRODUCT IS EQUIPPED WITH A 3-PRONG PLUG. 
This product is for use on 120 volts.
The cord has a plug (A) as shown. Use an adapter (C) (not included)
for connecting three-blade grounding -type plugs to two-slot recep-
tacles (B). The green grounding lug extending from the adapter must
be connected to a permanent ground
such as a properly grounded outlet
box. The adapter should not be used 
if a three-slot grounded receptacle is
available.
DO NOT DEFEAT THE SAFETY
PURPOSE OF THIS PLUG IN ANY
WAY.

The length of cord used on this appliance was selected to reduce
the hazards of becoming tangled in, or tripping over a longer cord. If
a longer cord is necessary, an approved extension cord may be
used. The electrical rating of the extension cord must be equal to or
greater than the rating of the product. Care must be taken to
arrange the extension cord so that it will not drape on obstacles
where it can be pulled on by children or accidentally tripped over.

INSTALLATION
You must install the Window Sealing

lower window sash, at its widest
point. See Figure 3.
Write your measurement
here:____________ 
You may close the window
temporarily.

2.If your window has a screen or

storm window, measure the dis-
tance between the front of the
window (the side facing inside) to
the screen or storm window. If
that measurement is less than
five (5) inches, you will need to
remove the screen or storm win-
dow before you can install the
Window Sealing Frame.

3.Place the Window Sealing Frame

on a flat surface, rim-side up,
with the locking clamp away from
you. See Figure 4.
