Installation to Concrete Ceilings

WARNING

•Concrete must be 2000 psi density minimum. Lighter density concrete may not hold concrete anchor.

•Make sure that the supporting surface will safely support the combined load of the equipment and all attached hard- ware and components.

1 Place projector mount assembly (A) on ceiling as a template and mark the center of the two mounting holes. Drill two 1/4" (6 mm) dia. holes to a minimum depth of 2.5" (64 mm). Attach projector mount assembly (A) using two Alligator® concrete anchors (M), two flat washers (K), and two #14 x 2.5" wood screws (L) as shown in Illustration A and 1, 2 and 3).

NOTE: Mounting slots on projector mount assembly allow for 30° (±15°) of swivel adjustment before fully securing wood screws.

Tighten wood screws (L) using 3/8" (10 mm) socket or open end wrench or phillips screwdriver until projector mount assembly (A) is firmly attached.

WARNING

•Tighten wood screws firmly, but do not overtighten. Overtightening can damage the screws, greatly reducing their holding power.

•Never tighten in excess of 80 in • lb (9 N.M.).

WARNING

•Always attach concrete anchors directly to load-bearing concrete.

•Never attach concrete anchors to concrete covered with plaster, drywall, or other finishing material. If mounting to concrete surfaces covered with a finishing surface is unavoidable, the finishing surface must be counterbored as shown below. Be sure concrete anchors do not pull away from concrete when tightening screws. If plaster/drywall is thicker than 5/8", custom fasteners must be supplied by installer (not UL approved).
