1 Read instructions through completely before proceeding.

2 Follow instructions carefully. Installation contrary to instructions invalidates

warranty.

3 Do not lift case in center. Lift the ends simultaneously to avoid damage

to case and surface.

4 Entire bottom of screen case should be unobstructed to permit proper

operation of automatic trap door, and access to bottom panel for making

electrical connections or servicing.

5 Screen should be installed level (using a carpenter's level).

6 Nothing should be fastened to screen dowel, viewing surface or auto matic

trap door.

7 Operating switch (es) packed separately in screen carton. Do not discard

with packing material.

8 Screen operates on 220V AC, 50 Hz., 1 ph. current.

NOTE: Screen has been thoroughly inspected and tested at factory and found

to be operating properly prior to shipment.

These instructions are meant as a guide only. They do not imply any responsibility

on the part of the manufacturer for improper installation or faulty workmanship at

the jobsite.

Hanging Screen

Planning Installation:

1 When locating viewing surface and checking clearance for screen's operation,

remember surface is not centered in case, but rather is offset to audience's

right (see drawing on reverse). Normally viewing surface, not case, should be

centered in room or viewing area.

2 Entire bottom of case must be readily accessible after installation is complete.

3 Hinge on automatic trap door must be permitted to operate freely. Front and

back of case must be straight—not forced to warp or bow. Hinges must be free

from mastic or paint build-up, and doors must be unob structed by ceiling tiles.

4 Do not use screen case to support adjacent sections of ceiling.

Hoisting Screen into Position:

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 must be installed level for satisfactory operation. Use a carpenter's

level.

3 Installer must insure that fasteners used are of adequate strength and suitable

for the mounting surface chosen.

4 Bottom of case should be flush with finished ceiling.

5 After case is mounted, remove two plates securing operating door to bottom

panel. Test door's freedom to operate by pushing up gently with fingers.

6 Do not seal unit in ceiling until electrical connections have been made and

screen has been operated successfully.

Finishing Case:

1 If case is painted, slots around doors should be shielded to protect viewing

surface from paint splatters or overspray.

2 If trim pieces must be attached to case, do not permit screws to pro trude

through ¾" wall of case. Do not attach trim with nails.

Electrical Connections

Screen operates on 220V AC, 50 Hz., 1 ph. current.

Junction box is located at left end of screen case and may be exposed by opening

access door and removing junction box cover. Automatic trap door is held shut

by viewing surface and must not be forced open. Junction box contains brown,

black and blue pigtail leads and green internal ground wire, per wiring diagram on

reverse.

Installation/Operating Instructions

Caution

Printed in U.S.A.

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 wiring

diagram, and wiring should comply with National and local electrical codes.

All operating switches should be "off" before power is connected.

When screen is first operated, be cautious! If automatic trap door does not drop

open immediately when switch is flipped "down", return switch to "off" and free trap

door and/or recheck electrical connections before proceeding. Cycle unit down

and up several times to confirm satisfactory operation.

220V Single Station Control—3-position up-off-down switch permits operation to

be stopped at any point. Factory adjusted limit switches automatically stop screen

when fully down or fully up.

220V Multiple Station Control (Not CE approved)—Switches are similar in ap-

pearance to 220V Single Station Control. Screen stops when switch is released

and may be restarted in either direction. Factory adjusted limit switches stop

screen automatically when fully down or fully up.

24V Control (CE approved)—Three-button up-stop-down switches stop at any

point desired, operate in any sequence. Factory adjusted limit switches automati-

cally stop screen when fully down or fully up.

Key Operated Switching (Not CE approved)— Two kinds of key-operated

switches are optionally available with this unit. 1 The key-operated power supply

switch controls power to the screen and switches. When it is "off", the switches

will not operate screen. Key may be removed from the switch in either "on" or "off"

position. 2 A three-position key switch permits the screen to be operated directly

by key. In this case, the screen's operator must always have a key.

RS232/Ethernet—Serial communication and network communication optionally

available with wall switches, RF or IR remote.

Please Note: Screen limits are factory set for optimum performance of

the screen. A procedure is outlined below for minor tweaks, but any

adjustment of these limits may negatively affect the flatness of the

screen surface and could also void the warranty. Please check with

Draper prior to resetting screen limits.

CAUTION: Always be prepared to shut screen off manually when new

adjustment is being tested. Screen may be severely damaged if viewing

surface is allowed to run too far up or too far down

CAUTION: Be sure all switches are in "off" position before adjusting

limit switches.

Adjusting "fully up" position — "Up" limit switch, located immediately 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 machine screws

which hold limit switch bracket in place. Turning these screws clockwise will raise

limit switch; turning them counterclockwise will lower it.

Raise switch only in quarter-turn increments. When operating properly 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" limit switch is located on left side of

limit switch assembly immediately behind access door on left end of case. Left

hand, hex head machine screw contacts limit switch button to shut screen off in

"down" position. Turning this machine screw clockwise will allow viewing surface

to run farther down before stopping. Turning it counterclockwise will cause sur-

face to stop in a less extended position. At no time should viewing surface be

unrolled enough to expose any part of screen roller. Be sure nut on machine

screw is tight against steel plate before closing access door.
