C - HANGING THE PROJECTOR LIFT
The VU-PRO projector lift is designed to mount recess into the ceiling, supported by four 1/2
inch threaded rods (not provided) - see the data sheet at the end of this manual for dimensions.
Dimension “SP” on the data sheet is based upon the 3/4” thick ceiling closure panel shipped with
the unit - if the final thickness of actual panel is 1” or more, the difference between 3/4” and the
actual thickness should be added to dimension “SP”.
Each threaded rod should be secured by a pair of nuts as shown in Figure 2. The nuts should be
adjusted such that all four rods are sharing the load roughly equally, then the pairs tightened
against each other to securely lock the connection.
Determine the desired location for the projector lift, and install per the following guidelines:
1. Unit should be level, with weight
shared roughly equally by the four
threaded rods.
2. It is recommended that the supporting
structure be able to carry at least four
times the total weight of the unit,
including projector weight.
3. Access to control box - refer to figure
4 - should be provided in case service
is required. Optionally, the control
box can be rewired and relocated to a
different location. Refer to the wiring
diagram at the end of this manual.
4. Attach a safety cable to the outer frame of the unit, and secure the other end to any nearby
attachment point that will be strong enough to catch the lift if it should fall.
5. Do not use this unit to support other fixtures, such as lighting, fans, etc.
