ATTACHING THE PROJECTOR TO THE CEILING MOUNT

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 the heads of each of the 7/8” socket head screws rest within the matching final location of the RPA mount head. At this point the silver 3/8” spacers should be between the Attachment Plate and 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.
