Installing Optional Ceiling Closure
If your LCD Lift is equipped with an optional ceiling closure system, it can be
used as is, or in conjunction with a piece of existing ceiling tile.
➀ If installing with ceiling tile, you may need to cut tile so that its overall
dimensions are the same as (or slightly less than) the closure panel. Place
tile into trim frame. Lay closure panel on top (back side) of ceiling tile, and
tighten screws to hold in place.
➁ If installing large closure, attach brackets to bottom of projector plate
(see drawing at right).
➂ Attach
5
/

" threaded rods to slots in projector plate or brackets.
➃ Run unit “up” until bottom pan stops at highest position. Mark po si tion on
5
/
16
" rods even with ceiling level and cut rods to length (removing from
pan if convenient).
➄ Run unit “down” until bottom pan stops at “show” position.
➅ Attach closure to lower end of
5
/
16
" rods by slipping into four corner slots
and secure with nuts above and below slots.
➆ Run unit “up” again to highest position. Measure distance by which panel
fails to reach required “closed” height for sur round ing ceil ing.
➇ Run unit “down” then re-adjust mounting of
5
/
16
" rods in traveling grid to
raise panel required distance.
Caution: Make sure nuts are completely tightened.
➈ Test unit operation to confi rm that panel will stop in closed position just
before touching ceiling.
Caution: DO NOT hang from, "ride" or pull down on the unit. This
could create a failure and cause damage and/or injury.
NOTE: Immediately upon completion of the surrounding ceiling, unit should
be operated to confi rm that optional ceiling closure panel stops just short of
touching ceiling in closed position.
