Installation to Concrete Ceilings
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.).
2 | 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 concrete anchors (G), two flat washers (E), and two #14 x 2.5" wood screws (F) as shown in fig. 2.6 and 1, 2 and 3 (right). Tighten wood screws (F) using 3/8" (10 mm) socket wrench, phillips screwdriver or 10mm open end wrench until projector mount assembly (A) is firmly attached.
NOTE: It is the responsibility of the installer to verify that the ceiling will safely support the combined load of all attached hardware and components.
Skip to step 3.
WARNING
•Concrete anchors are not intended for attachment to concrete ceiling covered with a layer of plaster, drywall, or other finishing material. If mounting to concrete ceiling covered with plaster/drywall is un- avoidable, plaster/drywall (up to 5/8" thick) must be counterbored as shown below. If plaster/drywall is thicker than 5/8", custom fasteners must be supplied by installer.
