Caution
Read instructions through completely before proceeding; keep them for future reference. Follow instructions carefully. Installation con trary to instructions in val i dates warranty. Care in mounting and correct operation will mean long and satisfactory service from your Draper screen. Allow enough access to remove front cover should fabric be come damaged or should other service be required.
Screen should be installed level (using a carpenter’s level). Nothing should be fastened to screen dowel or viewing surface Operating switch(es) is packed separately in screen carton. Do not
discard with packing material. Screen operates on 220V AC, 50 Hz., 1ph. current.
NOTE: Screen has been thoroughly inspected and tested at factory and found to be operating properly prior to shipment.
Hanging Screen
When locating viewing surface and checking clear ance for screen operation, remember surface is centered in the length of the case. Regardless of mounting method used, the following points apply: Mounting brackets are packed separately in carton. Engage each bracket with top of housing as shown below and tighten set screws. A bracket should be within 46 cm of each end of screen case. Brack ets can be removed and case mounted with lag screws through top of case (holes drilled on site). Screen should be positively and securely supported so that vibration or even abusive pulling on viewing surface will not weaken in stal la tion. Installer must insure that fasteners used are of adequate strength and suitable for the mounting surface chosen. Supporting hardware (chains, cables, rods, etc.) must be essentially vertical. Entire bottom of case must be readily accessible after in stal la tion is complete.
Typical Installation
Case dimensions on page 3.
Front, back and top of case must be straight—not forced to warp or bow. If case is painted on location, removal of roller/fabric assembly is
recommended prior to painting. If not removed, slot on bottom of case should be shield ed to protect view ing surface from paint splatters or overspray. Do not seal unit in ceiling until elec tri cal con nec tions have been made and screen has been op er at ed successfully.
Electrical Con nec tions
Screen operates on 220V AC, 50 Hz., 1 ph cur rent. Junction box is lo cat ed just above the bottom access panel at left end of screen (stan dard, right end may be specifi ed). Remove the bottom access panel for access to the junction box cover. (See Bottom Access Panel Removal instructions below). Remove four (4) hex head screws that secure the cover to the junction box to expose the ter mi nal strip per wiring diagram on page 4. If optional low voltage control or video interface control is specifi ed and factory installed, please refer to wiring diagram on page 3. Screen is shipped with internal wiring complete and control switch(es) fully boxed. Wire to connect screen to switch(es) and switch(es) to power supply should be furnished by installer. Con nec tions should be made in ac cor dance with attached wiring diagram, and wiring should comply with national and local electrical codes.
All operating switches should be “off” before power is connected.
Bottom Access Panel Installation/Removal
Bottom access panel hooks over the lower in side edge of the screen hous ing and then is pivoted downward until the engagement brackets on each end of the bottom panel click into place with the ball detents on each endcap. Make sure bottom access panel clicks in place at each end of its length. Remove bottom access panel by pushing up at each corner of panel ad ja cent to slot in bot tom of the hous ing. With bot tom ac cess panel an gled up ap prox i mate ly at 20° it can be lift ed off of the lip of the housing and then lowered out of the housing completely.
With bottom access panel angled up approx. 20 degrees, engage hook on the panel with lip of the housing
Using the hook and lip as a pivot, pull the panel downward until the engagement brackets click into place with the ball detent on each endcap

Motorized Roller/Fabric Installation
The bottom access panel must be removed fi rst. The motor end mounting bracket has a metal bracket with snap ring for
accepting motor head. Back out the four set screws in bracket until they are fl ush with top side of bracket.
To engage the motor end bracket fl ange above the two channels in the top of the screen housing, rotate the bracket approximately 45° coun ter clock wise to allow the top surface of the motor bracket to rest fl at against the top inside of the housing. Rotating the bracket clockwise until it is engaged with the chan nels, slide it along the length of the housing against the electrical junction box.
Engage the idler end bracket (rectangular mounting pad) in the same manner as the motor end bracket and slide it toward the opposite end of the screen housing. Do not tighten the set screws on this bracket

and centered in case. Locate the black washer and retaining clip
attached to the instruction sheet.
Note: This step requires two people to perform safely. Raise the roller/fabric
assembly up into the screen housing and en gage the head of the motor completely into the motor mount ing bracket, making sure the snap ring engages with the motor and that the limit switch ad just ing knobs are visible from the bottom of the screen housing.
While supporting the idler end of the roller, slide the idler end mount ing bracket toward the roller. In sert the roller pin into the nylon bush ing on the idler end mount ing brack et.
The roller idler pin needs to go through the idler brack et far enough to al low the washer and re tain ing clip to be re in stalled on the pin.
Failure to replace the wash er and re tain ing clip could re sult in the sep a ra tion of the roller from the brackets.
The roller/fabric assembly and roller brackets may need to be slid left or right in the mounting channel of case to center fabric within screen case.
Securely tighten the set screws on roller mount ing brackets. Con nect the elec tri cal plug from the mo tor to the mat ing sock et on the
junc tion box. Re in stall the bot tom access panel as pre vi ous ly de scribed.

Operation
When screen is fi rst op er at ed, be cau tious! Cy cle unit down and up sev er al times to con fi rm sat is fac to ry operation. 220V SINGLE STATION CON TROL—3-position UP-OFF-DOWN switch permits operation to be stopped at any point. Fac to ry ad just ed limit switches au to mat i cal ly 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 au to mat i cal ly when fully up or fully down.
24V CONTROL—Three-button UP-STOP-DOWN switches stop at any point desired, operate in any se quence. Factory adjusted limit switches automatically stop screen when fully up or fully down. Installer should incorporate an all-pole disconnect in the fi xed wiring.
220V & 12V VIDEO INTERFACE CONTROL—(Not CE Approved) Allows screen to be con trolled by a trigger signal—when the signal comes on, the screen de scends automatically. Two versions: Model VIC220 in te grates screen operation with a DRAPER video projector lift or a video projector or tuner with a 220V switched outlet. Model VIC12 interfaces with a 12V switched outlet. Both available with an override switch (VIC–OS), per mit ting in de pen dent operation. VIC–OS not avail able with factory installed VIC220 & VIC12.
KEY OPERATED SWITCHING—(Not CE Approved) Two kinds of key­op er at ed switch es are optionally available with this unit.
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.
A three-position key switch permits the screen to be op er at ed 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.
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” stopping po si tions, refer to drawing below and determine whether you need to adjust the white socket or the yellow socket, and proceed as fol lows: CAUTION: Be sure all switches are in “off” position before adjusting 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 damaged if viewing surface is al lowed to run too far up or too far down.

ADJUSTING WHITE SOCKET—White socket is located on the motor end of screen roller and is accessible to a small fl at screwdriver. Turning the socket counterclockwise will allow the roller to run farther up or down (as appropriate). Turning it clockwise will shorten op er a tion, caus ing it to stop sooner. One full revolution of the socket will alter the stopping position of the viewing surface by ap prox i mate ly 32 mm. ADJUSTING YELLOW SOCKET—Yellow socket is located on the motor end of screen roller and is accessible to a small fl at screwdriver. Turning the socket counterclockwise will allow the roller to run farther up or down (as appropriate). Turn ing it clockwise will cause the roller to stop sooner. One full revolution of the socket will alter the stopping position of the viewing surface by ap prox i mate ly 32 mm. AT NO TIME SHOULD VIEWING SURFACE BE UNROLLED ENOUGH TO EX POSE ANY PART OF SCREEN ROLLER.
Tab-Tension Adjustment Procedure for Access/Series V
Draper’s Tab-Tensioning System is factory­set, and under normal circumstances will not require fi eld adjustment. If, however, you notice wrinkles, waves, or other indications that the tensioning cables need to be adjusted, follow the procedure below.
Determine which side requires
Dowel
adjustment. Secure dowel with one hand.
Caution: Do not touch or bend surface.
Using Philips-head screwdriver, depress spring-loaded adjustment screw (see diagram at right) and slowly turn clockwise to tighten tension, or counterclockwise to loosen tension. The screw adjusts in ¼ turn increments. Adjust only one increment (¼ turn) at a time. If problem is not corrected, leave screen in position for 24 hours to allow surface material to stretch into position. If problem still is not corrected, repeat steps 2 and 3.
