Hanging Screen
General:
When locating viewing surface and checking clear ance for screen’s op er a tion,
remember surface is centered in case. Screen is normally recessed above
ceil ing and may be installed in a varie ty of ways. See typical in stal la tion
detailed on back of this sheet. Re gard less of mounting method used, the
following points apply:
①
Screen should be lifted into position only by the mounting brackets.
Keep case level by lifting both ends simultaneously to prevent
surface damage. Never attempt to lift screen along its length.
②
Screen should be positively and securely sup port ed so that vibration or
even abusive pulling on viewing surface will not weaken in stal la tion.
③
Installer must insure that fasteners used are of adequate strength and
suitable for the mounting surface chosen.
④
Entire bottom of case must be readily accessible after installation is
complete.
⑤
Hinge on bottom board and particularly hinge on automatic trap door of
screen must be per mit ted to operate freely. Front and back of case must
be straight—not forced to warp or bow. Hinges must be free from mas tic
or paint buildup, and doors must be un ob struct ed by ceiling tiles.
⑥
Do not use screen case to support adjacent sections of ceiling.
⑦
If trim pieces must be attached to case, do not permit screws to pro trude
through 19 mm (¾") wall of case. Do not attach trim with nails.
⑧
If case is painted, slots around doors should be shielded to protect
viewing surface from paint splatters or overspray.
⑨
Do not seal unit in ceiling until electrical connections have been made
and screen has been operated successfully.

Screen is shipped with internal wiring complete and control switch(es) fully
boxed. Wire connecting screen to switch(es) and switch(es) to power supply
should be furnished by installer. Connections should be made in accordance
with attached wiring diagram, and wiring should comply with National and
local electrical codes.
ALL OPERATING SWITCHES SHOULD BE “OFF” BEFORE POWER IS CON NECT ED.
Operation
When screen is fi rst operated, be cautious! If automatic trap door does not
drop open im me di ate ly when switch is fl ipped “down”, re turn switch to “off”
and free trap door and/or recheck elec tri cal con nec tions before proceeding.
Cycle unit down and up several times to confi rm sat is fac to ry operation.

stop screen when fully down or fully up.
220V Multiple Station Control (Not CE approved)—Switches are similar
in ap pear ance to 220V Single Station Control. Screen stops when switch
is re leased and may be re start ed in either direction. Factory adjusted limit
switches stop screen automatically when fully up or fully down.
24V Control—Three-button up-stop-down switch es stop at any point de sired,
operate in any sequence. Factory adjusted limit switches au to mat i cal ly stop
screen when fully up or fully down. Installer should incorporate an all-pole
disconnect in the fi xed wiring.

Adjustments
Screen has been factory set and should not nor mal ly require further ad just ment. However, if you desire to change the “up” and “down” stop ping positions,
proceed as follows:
CAUTION: Be sure all switches are in “off” position before ad just ing limit
switches. Always be pre pared to shut screen off man u al ly when new ad just ment is being tested. Screen may be se vere ly dam aged if viewing surface is
al lowed to run too far up or too far down.
Adjusting “fully up” position — “Up” limit switch, located im me di ate ly
above left end of automatic trap door, is tripped as door closes. If door does
not close fully, limit switch should be raised slightly. If door closes too tightly,
switch should be lowered slightly.
Remove steel plate attached to threaded neck of “up” limit switch by removing
hex nut securing it. Removing plate exposes three Phillips head ma chine
screws which hold limit switch bracket in place. Turn ing these screws clockwise will raise limit switch; turning them coun ter clock wise will lower it.
Raise switch only in quarter-turn increments. When operating prop er ly automatic trap door should close gently and rest against but not press on rubber
bumpers above it. Adjusting automatic door so that it closes too tightly will
damage screen.
Adjusting “fully down” position — “Down” stopping position may be adjusted by turning the white limit switch adjustment socket. The white socket is
located on the left end of screen roller and is accessible to a screw driv er/Allen
wrench (4mm or
when bottom board is also open. (Do not adjust the yellow socket which is
next to and in back of the white socket). Turning the white socket coun ter clock wise will allow the viewing surface to run farther down. Turning it clock wise will shorten the viewing surface, causing it to stop in a less extended
position. At no time should viewing surface be unrolled enough to expose any
part of screen roller.
