be used as is, or in conjunction with a square of existing ceiling tile. See
installation instructions included with ceiling closure.

Installing Optional Ceiling Trim Kit
The Scissor Lift SL is available with a ceiling trim kit, which consists of
the lower section of the Environmental Air Space Housing and the optional
closure panel. See installation instructions included with Ceiling Trim Kit.
Installing Projector Using Universal Projector Mount
The Universal Projector Mount includes:
-2 x long arms
-4 x short arms
-4 x M3, 4 x M4, 4 x M5 and 4 x M6 mounting bolts (30mm in length)
-4 spacers (½" [13 mm],
5
/8" [16 mm], ¾" [19 mm],
7
/8" [22 mm])
 Determine which size mounting bolts suit your projector, and set others
aside. They are no longer required. If your projector has only three
mounting holes, set aside one of the mounting arms (see Fig. 3).
 Attach the appropriate mounting arms to the rectangular plate via center
bolt. Spread out the arms so each end is over one of the mounting holes.
 Connect projector mounting arms.
 Tighten the mounting bolts.
 Use the ¼" (6.35 mm)-20 bolts and springs which hold the rectangular
plate to the bottom pan to adjust roll and tilt (the springs will ensure that the
projector is held still during motion). The center
5
/16" (8 mm) bolt provides
Yaw adjustment (see Fig. 4).

Installing Optional Environmental Air Space Housing
The Environmental Air Space Housing is shipped in pieces, and must be
assembled by the installer. The height of the Environmental Air Space Hous
-
ing is set by drilling out the knockouts at the desired locations then using
screws to connect side panels. It is recommended that an access panel be
installed in the ceiling to allow future access. The optional environmental air
space housing must be installed to isolate the lift from the “other space used
for environmental air.”
Includes trim ring for ceiling opening.
See installation instructions included with Environmental Air Space Housing.
Please Note: When using the Environmental Air Space House "SL" size,
the mounting brackets attached to the top four corners of the Scissor
Lift SL must be removed, and replaced with brackets which are shipped
with the Environmental Air Space Housing (see Fig. 5).
Please Note: The factory wiring of 'UP' Limit Switch MUST ALWAYS
be used when SL is installed in Environmental Air Space Housing and
optional ceiling closure.

Scissor Lift SL Inspection and Maintenance
Draper recommends inspecting the Scissor Lift SL at least annually or
every 300 cycles—whichever comes first.
A recommended maintenance schedule includes:
-Cables: Check for fraying
-Fasteners along scissor arm assemblies: Make sure they are not loose. If
any are loose, hand tighten the nuts. (Please Note: there is no need to
tighten nut in the top scissor which slides back and forth in the side slot in
the lift. Tightening this fasteners assembly will cause the unit to lock up
and lead to damage to the unit.)
-Closure: Make sure threaded rod remains seated firmly in the closure
panel corners, and that the nuts remain tight. If they are loose, tighten
them.
