Installation in a Suspended Ceiling (using threaded rods)
WARNING: Plenum rating requires hardwiring through the
provided strain relief, use of Class II control wiring, and all
open holes in housing (except joist tabs) must be sealed using
foil tape. See wiring instructions in this manual and follow all
local building and electrical codes.
The lift housing can be suspended from three 3/8-in.-dia.
threaded rods (not supplied by Chief Manufacturing) that are
secured to a structural cross brace in the ceiling. Insert the
rods through the three holes on the top side of the lift hous-
ing, and secure them to the housing with two jam nuts (one
inside, one outside). See Fig. 2 and Fig. 3.
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.
NOTE: Installing turnbuckles on the threaded rod will
make it easier to level the unit.
After installing the lift, use the test push button to carefully
operate the lift all the way up and down to be sure the clear-
ances are adequate.
