Scissor Lift by Draper, Inc.
Operation
When unit is first operated, be cautious! If unit fails to operate when the
toggle switch is flipped "down", return switch to "off" and recheck electrical
connections before proceeding. Cycle unit down and up several times to
confirm satisfactory operation.
Standard Single Station Control—One, 12 volt toggle switch: moving 3-
position toggle switch to "down" position will start lift down. Moving toggle
switch to "up" will start lift up. When lift is in "show" position, travel will
automatically be stopped by factory set limit switches. Whenever switch is
placed in center "off" position, operation will stop. One, 12 volt key switch will
lower lift from "show" to "service" position.
Video Interface Control—This optional 12 volt control device allows the
Scissor Lift switch to control the operation of a Draper motorized projection
screen via a relay.
Multiple Station Control—Optional, moves lift from "stored" to "show"
positions only. Each switching station has a three-button switch with "up",
"down", and "off" buttons. Lift starts up or down when appropriate button is
pressed, and may be stopped by pressing "off" button. Factory set limit
switches stop lift automatically when projector is in "show" position.
Key Operated Switch—If ordered, a single station, key-operated three
position (up/off/down) switch is available. Multiple Station Control required for
this option. Moves lift from "stored" to "show" positions only.
Infrared or Radio Frequency Remote Control—If ordered, a three-button
transmitter is provided, with "up", "down", and "stop" buttons. Unit starts up or
down when appropriate button is pressed, and may be stopped by pressing
"off" button. Factory set limit switches stop unit automatically when projector
is in "show" position. Multiple Station Control required for this option.
Installing Optional Ceiling Closure
Your Scissor Lift can be equipped with an optional ceiling closure system. To
install it:
À Remove closure and all mounting hardware from carton.
Á The optional ceiling closure can be mounted in either of the following
styles:
A. If ceiling tile is to be inserted in the closure, this may be done now, or
later when the rest of the ceiling is installed (permitting a better match). Cut
tile so that its overall dimensions are the same as (or slightly less than) the
closure panel. Attach to the closure panel with mastic.
B. Position one pre-cut aluminum tee along outside edge of panel so arm
extends under and rests on the panel (or tile if tile is being used). Be
careful not to compress the tile. Drill three holes through rib of tee into
edge of panel and pop rivet into place.
C. Follow same procedure with remaining 3 tees.
NOTE: Since tees comprise part of exposed trim, care should be taken
to ensure accurate fit.
 Attach (2) labeled mounting angles to the corresponding holes in the
bottom pan with the supplied hardware.
à Attach other (2) labeled mounting angles at 90° to previous angles (right to
left) in the corresponding holes with the supplied hardware.
Ä Attach one of four
3
/
" threaded rods by passing the rod through one of the
8
four corner holes, in the angles and secure with nuts top and bottom.
Approximately ½" of rod should extend above grid.
Å Run unit "up" until bottom pan stops at highest position. Mark position on
3
/
" rod that is even with ceiling level and cut rod to length (removing it from
8
pan if convenient). Cut remaining three rods to same length.
Æ Run unit "down" until bottom pan stops at "show" position. Secure all four
3
/
" rods to traveling pan in same fashion as first one.
8
Ç Attach closure to lower end of each
each rod to firmly clamp fixtures on top of panel.
È Run unit "up" again to highest position. Measure distance by which panel
fails to reach required "closed" height for surrounding ceiling.
É Run unit "down" then readjust mounting of
panel required distance.
NOTE: Rods should not extend more than 1" above the angles attached
to the pan. Cut extra rod off if necessary.
Test unit operation to confirm that panel will stop in closed position just
11
before touching ceiling.

Installing Projector
Depending on job conditions and projector, it may be easier to remove
optional ceiling closure panel before installing projector.
Generally, the video projector should be suspended from the bottom pan
according to projector manufacturer's instructions and using recommended
standard ceiling mounting hardware (supplied by others).
The Scissor Lift has a grounded 110v AC, 60Hz power cord for projector
power supply. The power cord is laced down the back scissor and is "hot" at
all times.
Control cables should be laced through our Cable Management System. This
will ensure that cords do not become tangled and damaged during Scissor Lift
operation.
Unit and projection system should be operated, checked and adjusted as
necessary at this time.
After testing operations, the optional closure panel should be reattached. Be
sure to use Loc Tite, or other thread locking compound on the nuts.
NOTE: Immediately upon completion of the surrounding ceiling, units should
be operated to confirm that optional ceiling closure panel stops just short of
touching ceiling in closed position.
Warning: Keep fingers and other objects away from automatic ceiling closure
and scissor mechanisms when unit is operating. Serious injury or damage
could result.
