Owner’s Manual
Model A Electriscreen
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 S tewart Filmscreen product.
About your Model A Electriscreen
This is one of Stewart’s most popular electric roll up unit s because it can
accommodate screen sizes up to 9’ x 12’ / 180” diagonal (2.7 m x 3.6 m /
4.5m diagonal). Typically, the screen housing is hidden above the ceiling,
and the screen descends through a slot in the ceiling.
Note: This manual refers to “AC” to represent electrical power . Your
location may use 120V, 220V or other electrical power. Screen systems are
manufactured using the electrical power type specified for the location. Use
appropriate power sources for your location.
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.
Ensure that the mounting area and electrical connection are
prepared.
Check the size and weight of the screen to be inst alled 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.
