Caution
➀ Read instructions through completely before proceeding; keep them
for future reference. Follow instructions carefully. Installation contrary to
instructions invalidates warranty. Care in mounting and correct operation
will mean long and satisfactory service from your Draper screen.
➁ Allow enough access to remove front cover should fabric become
damaged or should other service be required.
➂ Screen should be installed level (using a carpenter’s level).
➃ Nothing should be fastened to screen dowel or viewing surface
➄ Operating switch (es) is packed separately in screen carton. Do not
discard with packing material.
➅ 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 clearance for screen operation,
remember surface is centered in the length of the case. Regardless of
mounting method used, the following points apply:
➀ Mounting brackets are shipped attached to the case. 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. Brackets can be
removed and case mounted with lag screws through top of case (holes
drilled on site).
➁ Screen should be positively and securely supported so that vibration or
even abusive pulling on viewing surface will not weaken installation.
➂ 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.
➃ Entire bottom of case must be readily accessible after installation is
complete.

Typical
Installation
➄ Front, back and top of case must be straight—not forced to warp or bow.
➅ 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 shielded to protect viewing surface from paint splatters or
overspray.
➆ Do not seal unit in ceiling until electrical connections have been made and
screen has been operated successfully.
Electrical Connections
Screen operates on 220V AC, 50 Hz., 1 ph current.
Junction box is located just above the bottom access panel at left end of
screen (standard, right end may be specified).
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 terminal strip
per wiring diagram on page 3.
If optional low voltage control or video interface control is specified and factory
installed, please refer to wiring diagram on page 4.
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. 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 connected.
Bottom Access Panel Installation/Removal
Bottom access panel hooks over the lower inside edge of the screen housing
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 adjacent
to slot in bottom of the housing.
With bottom access panel angled up approximately at 20° it can be lifted off of
the lip of the housing and then lowered out of the housing completely.

Motorized Roller/Fabric Installation
Tab-Tension Adjustment Procedure for Access/Series V
The bottom access panel must be removed first.
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 flush with top
side of bracket.
To engage the motor end bracket flange above the two
channels in the top of the screen housing, rotate the
bracket approximately 45° counterclockwise to allow
Retaining
the top surface of the motor bracket to rest flat against
clip
the top inside of the housing. Rotating the bracket
Motor roller
Washer
clockwise until it is engaged with the channels, slide it assembly
along the length of the housing against the electrical
Idler end roller
mounting bracket
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 until the
roller/fabric assembly is installed, 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 engage the head of the motor
completely into the motor mounting bracket, making
sure the snap ring engages with the motor and that the
limit switch adjusting knobs are visible from the bottom
of the screen housing.
While supporting the idler end of the roller, slide the
idler end mounting bracket toward the roller. Insert the
roller pin into the nylon bushing on the idler end mounting bracket.
The roller idler pin needs to go through the idler bracket far enough to allow the
washer and retaining clip to be reinstalled on the pin.
Failure to replace the washer and retaining clip could result in the separation 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 mounting brackets.
Connect the electrical plug from the motor to the mating socket on the junction
box.
Reinstall the bottom access panel as previously described.
Draper’s Tab-Tensioning System is factory-set; under normal circumstances field
adjustment is not required. If you notice wrinkles, waves or other indications that
tensioning cables need adjusting, follow these steps:
➀ Determine which side requires adjustment.
Tensioning
➁ Secure dowel with one hand.

Adjustment
Screw
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.
➃ If problem is not corrected, leave screen in position for 24 hours to allow
surface material to stretch into position.
➄ If problem still is not corrected, repeat steps 2 and 3.
Motorized Roller/Fabric Removal
Reverse the instructions above “Motorized Roller/Fabric Installation” for removal of
the unit.
Operation
When screen is first operated, be cautious! 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 appearance 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 up or fully down.
24V CONTROL—Three-button UP-STOP-DOWN switches stop at any point
desired, operate in any sequence. Factory adjusted limit switches automatically
stop screen when fully up or fully down. Installer should incorporate an all-pole
disconnect in the fixed wiring.
220V & 12V VIDEO INTERFACE CONTROL—(Not CE Approved) Allows screen
to be controlled by a trigger signal—when the signal comes on, the screen
descends automatically. Two versions: Model VIC220 integrates 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), permitting independent operation. VIC–OS not available
with factory installed VIC220 & VIC12.
KEY OPERATED SWITCHING—(Not CE Approved) Two kinds of key-operated
switches are optionally available with this unit.
➀ 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.
➁ 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.

Limit Adjustments (Standard/Quiet Motors)
Tools needed: Flashlight, small flathead screwdriver/Allen wrench (4mm or 5/32").
Screen settings have been factory set as ordered and should not normally
require further adjustment. However, if you find it necessary to adjust for more or
less viewing area, proceed as follows.
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. When running up, the
dowel should never wrap over the roller. When run to the down limit, a
minimum of 1¼ wraps of fabric must remain on the roller.
The motor limit screws are normally located on the audience left of screen roller.
**Please Note: If the Access E/V is “Right Hand Motor” or “Waterfall”, the WHITE/
DOWN and YELLOW/UP limit screws are reversed. See graphic below.
"Down" Limit Adjustment
To Reduce Screen Drop
➀ Raise screen surface about 1' above desired setting and turn off.
➁ Turn the WHITE/DOWN limit screw clockwise (three screw turns = ½ roller
revolution).
➂ Test by running screen down and repeat steps 1 and 2 until desired position is
reached.
To Increase Screen Drop
➀ Run screen to the down limit.
➁ With the down switch on, turn the WHITE/DOWN limit screw counterclockwise
(3 turns of screw equals ½ roller revolution) to increase drop.
➂ Test by running screen up about 1' and back down to new down limit.
➃ Repeat steps 2 and 3 until desired position is reached.
CAUTION: At least 1¼ wraps of fabric must remain on the roller when
screen is at the down limit!
"Up" Limit Adjustment
Screen is Running Too Far Up
➀ Lower screen surface about 1' below desired setting and turn off.
➁ Turn the YELLOW/UP limit screw clockwise (3 screw turns = ½ roller revolution).
➂ Test by running screen up.
➃ Repeat steps 1 through 3 until desired position is reached.
Screen Needs to Run Up More
➀ Run screen down about 1' and turn off.
➁ With the up switch on, turn the YELLOW/UP limit screw counterclockwise (3
turns of screw equals ½ roller revolution).
➂ Repeat steps 1 and 2 until desired position is reached.
CAUTION: Do NOT allow the dowel to wrap up over the roller when the
screen is running up! This could damage the screen.
