1.Position the projector bottom-up. Consult the Attachment Plate Diagram for plate orientation, hole positions and required screws and spacers for your projector model. Insert and tighten each screw through an appropriate silver washer and lock washer, the designated holes in the Attachment Plate, then through any required spacers and finally into the projector ceiling mount holes.

2.Using the included gold hex key, install the six 7/8” socket head screws each through a 3/8” aluminum spacer and into the six threaded holes from the ceiling side of the attachment plate. Thread only enough to extend the screw to the bottom of the plate.

3.Insure that the RPA mount head is secure (see instructions included with the RPA mount) and oriented properly relative to the 7/8” socket head screw heads so that the mounted projector will face the screen. Use two people to lift and position the projection assembly so that

heads of each of the 7/8” socket head screws rest within the matching final location of the mount head. At this point the silver 3/8” spacers should be between the Attachment Plate the RPA mount head. The projection assembly may be lowered to allow the 7/8” screw

heads to rest on the RPA mount. However, a first person should continue to guide the projection assembly while and a second person uses the gold assembly wrench to tighten the 7/8” screws. When tightening these screws, do so in a pattern of incrementally driving each screw a little more into the attachment plate so that at any time the projection assembly is resting on as many screw heads as possible until all are tightened.

If the lens must be removed for any length of time it is recommended that a similar weight be suspended from the front of the attachment kit to balance the weight of the projector. This will minimize unusual stresses on the ceiling mount system.
