Installation Instructions
Determine the height of the top of the case from the floor.
This will be the height of the wall mounted "V" bar.
Hold the loose "V" bar to the wall at the height determined above
(MAKE SURE IT IS LEVEL), and mark the location for the screw
holes. To mount the "V" bar on solid concrete or masonry wall,
drill 5/16" holes and insert the lead shields. Fasten the "V" bar to
the wall using the #10 x 2" wood screws. If you are mounting to a
hollow wall, drill 1/2" holes and insert the toggle bolts. Then fasten
the "V" bar to the wall with the toggle bolts. Now set the case in
place on the wall with the "V" bar of the case nestled into the
"V" bar on the wall.
For Ceiling Suspension
Position and properly anchor screw hooks into ceiling, beam
or other solid surface. Then proceed to use the two "D" rings
that are factory mounted to the top of the case to hang the
case securely.
To Lower And Raise Picture Surface
To lower the picture surface, pull the screen down all the way.
Then hesitate and allow the screen to retract very slowly until it
locks in place. To raise the picture surface pull down on the pull
bail, then raise quickly, as a window shade. Keep control of the
picture surface. Do not allow it to roll uncontrolled into the case
or damage to the screen is sure to result.
Maintenance
Projection Screen Maintenance
Protect your screen by keeping it rolled in its case when not
in use. Always examine both front and back of surface before
rerolling into case to make certain screen is free of dust, dirt
or other foreign matter. Use a very soft duster brush to gently
remove foreign particles.
Case Maintenance
The case of the screen has a Resistovar finish. This finish is
resistant against: water, alcohol, marring, scratching, and nail
polish remover. To help maintain the best appearance of the
case it is recommended that the case be polished with any
reputable liquid or paste wax polish. An oil type polish is not
recommended because it allows for the collection of dust and
finger prints. When necessary, this finish may be wiped with
a damp soft cloth using a mild soap solution, rinsed with
clear water and dried with a soft cloth.
