Because of the wide variety of possible mounting situations, Chief Manufacturing can only provide general guidelines for preparing the location where the
WARNING: Be especially 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 situa- tions:
•Suspend the lift from threaded rods that secure to the structural cross brace.
•
General Guidelines
•Carefully determine the position 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 total weight of the equipment you intend to support overhead. If they cannot, the ceiling must be reinforced before you install the lift.
WARNING: Improper installation can result in serious injury! Plenum rated installations require electri- cally 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.
