SITE PREPARATION
Site Preparation
Because of the wide variety of possible mounting situations,
Chief Manufacturing can only provide general guidelines for
preparing the location where the SLEU will be installed. Study
the following information carefully, and adapt it as necessary to
fit your specific installation.
The installation instructions that follow cover the three most
common mounting scenarios:
• Suspended from a 1 1/2" NPT pipe that is secured to a
structural cross brace in the ceiling.
• Suspended from three 1/4" threaded rods that are
secured to the structural cross brace.
• Side-mounted to the ceiling joists, or secured to a wood
framework that is mounted to the ceiling joists.
IMPORTANT ! :
If the lift is to be installed in a suspended
ceiling, a CMA-240 Suspended Ceiling Installation Kit is
available as an accessory to fill gap(s) in the ceiling.

and verified.
2. Connect control wires to switch and route power, lift control,
projector power and signal wires to opening in ceiling.
(See figure 3) and (See figure 4)

Allow enough excess wiring and cable at the
opening in ceiling to allow wires and cables to be routed into lift
box prior to the lift box being placed into the ceiling.
