OWNER’S MANUAL

Congratulations on your purchase of the finest optical viewing screen
available anywhere in the world!

Please take a moment to review this manual—it will help ensure you many
years of trouble-free service from your new Stewart Filmscreen product.

About your 4-Way ScreenWall ElectriMask

Your 4-Way ScreenWall ElectriMask is a fixed frame with both vertical and
horizontal masking panels, enabling the viewer to obtain any aspect ratio.
The term aspect ratio refers to the format (width to height) in which your
video sources are produced. The masking panels are controlled by three
separate motors, allowing maximum control and adjustability.

The sizes and weights of the various 4-Way ScreenWall ElectriMask models
are listed in the charts in Figure 2.

Preparation

Specifications regarding the individual screen dimensions, weight, mounting
type, and controls are provided by the factory when the unit is ordered.
Before beginning the installation:

 Check the specifications for the type of mounting and switch

control to be used.

 Prepare the wall for electrical access to the motor(s) (audience

left).

 Make sure there is a clean surface on which to unroll the screen.
 Check the size and weight of the screen to be installed so that

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:

 Enough ladders for the personnel supporting the screen during

the mounting process

 A level
 Fasteners appropriate for the surface on which the screen is

being mounted (See instructions for the type of mount for
recommendations.)

 Phillips screwdriver
 5/8” (1.6 cm) hex head screwdriver or Allen wrench

Unpacking

Remove the outer plastic covering and white wrapping paper surrounding
the frame unit, if any. Do not remove the screen from the cardboard
shipping tube until instructed to do so.

PREPARING THE INST ALLATION

 Before proceeding with the installation of this screen,

take time to thoroughly read and understand these
installation and operation instructions.

 All electrical wiring installations must conform to local

and national codes and should be performed by
qualified service personnel.

 There 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.

Corporation cannot be liable for substandard or faulty installations.

Assembling the frame

Work in a clean area, making certain installers have clean hands and
clothes. Assemble the frame on the floor.

1. Connect the four pieces by matching the colored numbered dots
on the ends of the frame pieces. See Figure 3.

2. Secure with the supplied 1/2” (1.3 cm) Phillips pan head bolts.

Figure 4: Positioning the frame

Positioning the frame on the wall

1. Without the screen fabric attached, position the frame on the wall.

2. Make sure the unit is level and plumb. (You may need to use
shims between the brackets and the wall to achieve vertical
plumb).

3. Mark the position of the bracket holes on the wall. See Figure 4.

Note: Later, when the screen fabric is attached to the frame (next section),
you will hang the frame on the wall.

Caution

If the unit is not mounted so that it is level and plumb,
horizontal masking panels may jam on retraction.
