SMART-LIFT
The Model SL-236 Electric Ceiling Lift is a reliable,
heavy-duty video lift mechanism for LCD /DLP projectors
requiring an extended drop from their hidden location.
The ceiling lift is designed for home-theater, conference
room, or school applications.
The SL-236 provides an attractive solution to recess a
projector in the ceiling. The lift is suitable for finished or
suspended ceiling with a finish kit. The concealed bottom
can be finished to match existing ceiling design and color
to conform to room decor.
Plenum Rating requires use of Class II control wiring,
electrically hard wiring the unit, and all open holes in the
housing (except joist tabs) must be sealed using foil tape.

BEFORE YOU BEGIN

• CAUTION: To prevent damage to the ceiling lift, which could affect or void the factory warranty, thoroughly study
all instructions and illustrations before you begin to install or operate the lift. Pay particular attention to the "Impor-
tant Precautions" on Page 1.
• CAUTION: For smooth and reliable operation, the lift must be installed square and parallel in all dimensions. Avoid
stressing or twisting the lift at any time during installation.
• Because of the size and weight of the lift, Chief Manufacturing recommends that at least two people be available
when installing the lift.
• If you have any questions concerning this installation, contact Chief Manufacturing at 1-800-582-6480.
