time. You should remove it only after the unit is hung, all electrical
connections have been made, and the screen is in operation.

recessed electrical projection screen permanently. You
must be able to access and remove the unit should future
service 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.
Professional mounting techniques should be adhered to. Stewart
Filmscreen Corporation cannot be liable for substandard or faulty
installations.
Make sure that you mount the screen so that the electrical box is on the left
side (audience left).
Installing the unit
The Model B & Model C Electriscreens are ready to install into the ceiling or
soffit. A false ceiling is not intended to support the weight of a Model B &
Model C Electriscreens.
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.
2. Make sure the unit is level.

Use the 3-button switch or outboard switching network to control the screen.
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.
