you can plan for the number of people required for the mounting
procedure. You need at least two people to mount the smaller
screens; more are needed for larger, heavier screens.
You will need:
KEnough ladders for the personnel supporting the screen during
the mounting process
KA level
KFasteners appropriate for the surface on which the screen is
being mounted (See instructions for the type of mount for
recommendations.)
AB Electriscreen: Owner s Manual 3
PREPARING THE INSTALLATION
KBefore proceeding with the installation of this screen,
be sure to read and understand all the installation and
operating instructions thoroughly.
KAll electrical wiring installations must conform to local
and national codes and should be performed by
qualified service personnel.
KThere are no user-serviceable parts contained within
the unit.
Caution
During installation, do not place the unit on an unstable
cart, stand, table, or ladder. The unit may fall, causing injury
to a child or adult and damage to the unit.

Unpacking
1. Do not remove the wrapping paper rolled with the screen. You
should remove it only after the unit is hung and all electrical
connections have been made.
2. Remove the batten lock-down screws located on the back side of

future service to the internal roller tube/screen assembly
system be necessary.
Suggested solutions for removing the unit include:
KA removable ceiling cover plate under the mounting
location.
KAccess to the unit through an attic or overhead space.

rofessional mounting techniques should be adhered to. Stewart
Filmscreen Corporation cannot be liable for substandard or faulty
installations.

side (audience left).
Installing the unit
The AB Electriscreen is ready to install into the ceiling or soffit. A false
ceiling is not intended to support the weight of an AB Electriscreen.
The screen can be bolted directly to the support structure or suspended. If
the unit is to be mounted to plaster, drywall, masonry, or other type of
surface, use an appropriate fastener. (These might include toggle or molly
bolts or similar fasteners.)
1. Install the unit onto the support structure making sure that the
bottom of the case is flush with the finished ceiling, if any. Refer
to Figure 1.
2. Make sure the unit is level.

The method you use to raise and lower the screen depends on the type of
switch control device you have selected.
When you lower or retract the screen, it will stop at its preset limit. If an
obstacle (such as a person or furniture) gets in the path of the screen as it
is lowered, you should use the switch control to stop the screen's motion; it
will not automatically stop if it hits an obstacle.
In general, when the screen is not in use, you should store it in the fully
retracted position.
AB Electriscreen: Owner s Manual 11
OPERATING THE SCREEN
Caution

irreparable damage to the screen itself, resulting in voiding
the factory warranty.
Warning!
The screen is fully retracted when the batten is flush with
the bottom of the case. Do not attempt adjustments with
the yellow retraction UP) limit switch that will further retract
the screen. Incorrect adjustment of the switch will cause
severe screen damage. Please consult the factory if you

ADJUSTING THE SCREEN EXTENSION
Figure 6: Underside view
Limit Switches

AB Electriscreen: Owner s Manual 13
Modifying the extension of the screen
You can increase the extension of the screen up to 3" past the factory
preset stop, or you can decrease the extension by approximately 4-6" from
the factory preset stop. Do not attempt to modify the screen extension
beyond these recommended amounts.
The limit switches are located on the left side of the screen roller tube inside
the case, as shown in Figure 6.
To increase the screen's fully extended (screen down) stop position:
1. Lower the screen to its current stop position.
2. Locate the white extension (down) limit switch located on the left
side of the screen tube. Use a screwdriver to turn the switch in a
counterclockwise direction. If the power is on, the screen will
drop incrementally as the switch is turned.
Note: One complete turn of the switch will make approximately a
3/4" change in the screen's stop position.
To decrease the screen extension:
1. Lower the screen until it is extended about halfway down.
2. Locate the white extension (down) limit switch located on the left
side of the screen tube. Use a screwdriver to turn the switch in a
clockwise direction.
Note: One complete turn of the switch will make approximately a
3/4" change in the screen's stop position.
3. Activate the screen in the down direction until it reaches the
newly reduced stop position. Repeat this procedure until the
desired stop position is reached.
Once you have made the adjustment, whenever you lower the screen, it will
automatically stop at the new position.
Note: It is recommended that you make a note of any changes made to the
factory preset.

With reasonable care, you may expect many years of trouble-free use of
your Stewart projection screen.
We encourage you to keep your screen clean. To protect your screen when
it is not in use, store it in the fully retracted position.
Avoid getting any foreign material on the screen, as cleaning may prove
very difficult. It may not be possible to remove scratches, paint, ink, etc.
General maintenance
The screen surface on your AB Electriscreen is delicate. Special attention to
these instructions should be followed when cleaning.
KA draftsman-style brush may be used to lightly whisk away any
loose dirt or dust particles. (This type of brush is usually available
at office supply stores.)
KFor tougher spots, use a mild solution detergent, water, and a
sponge. Rub lightly. Blot with a damp sponge to absorb excess
water.
Do not use any other cleaning materials on the screen.
Replacement parts and service
No user-serviceable parts are contained within the unit. Contact your dealer
or the factory if you require part replacement or service.
