SMART-LIFTTM 236 Electric Ceilin g 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. Th e lift is suitable for finis hed 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 “Important 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.

PRETEST THE LIFT BEFORE INSTALLING
IMPORTANT: Before mounting the lift in the ceiling, perform
the following test to be sure that it operates properly and has
not been damaged during shipping.
1. Attach supports (not supplied) to the top of the lift (see
Figure 1).
2. S us pend the lif t at leas t 3 1/2 f eet hi g h from a su it ab le st ruc tur e
[i.e. s aw hor ses, ladd e rs , o r tab le s (s ee Figure 2)] .
NOTE: The supplied momentary push button and power cord can
be used to pre-test the lift (see and “OUTSIDE TERMINAL
WIRING EXAMPLES” on page 13).
3. Cycle the lift through the “show” and “service” positions, making sure the unit operat es smoothly.

PREPARE THE CEILING OPENING AND INSTALL THE LIFT
Because of the wide variety of possible mounting situations, Chief Manufacturing can only provide general guidelines
for preparing the location where the Smart-Lift wil l be i nst al led. Study the following information carefully, and adapt i t as
necessary to fit your specific installation.
WARNING: Be esp ecia lly aware of the weight of the lift, and the potential for personal injury or of damage to
the lift if it is not adequately mounted. The lift (without a projector) weighs approximately 85 lbs (38.5 kg).
The “General Guidelines” below, and the information on the following pages, covers the most common mounting situations:
• Suspend the lift from threaded rods that secure to the structural cross brace.
• Side-mount the lift to the ceiling joists or secure the lift to a wood framework mounting to the joists.
General Guidelines
• Carefully determin e the posit ion of the ceiling opening and its distance from, and orientation toward, the screen.
• If possible, prepare an area above the ceiling that is sufficiently larger than the lift, Leaving at least an 8” access to
all sides and above the top of the lift for any future maintenance or repair.
WARNING: Improper installation can result in serious personal injury! To avoid such injury, make sure
that the ceiling structural members can support a redundant weight factor five times the tota l w eight of the
equipment you intend to support overhead. If they cannot, the ceiling must be reinforced before you
install the lift.
WARNING: Improper inst allation can result in serious injury! Plenum rated installations require electrically hard wiring the unit through the provided strain relief, the use of Class 2 control wiring, and all open
holes in the housing (except joist tabs) must be sealed using foil tape. You must adhere to all local codes.
CAUTION: For smooth and reliable operation, the lift must be installed square and parallel in all dimensions.
Avoid stressing the lift at any time during installation.
