Installation to Solid Concrete and Cinder Block

WARNING

•When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" (35 mm) of actual concrete thickness in the hole to be used for the concrete anchors. Do not drill into mortar joints! Be sure to mount in a solid part of the block, generally 1" (25 mm) minimum from the side of the block. Cinder block must meet ASTM C-90 specifications. It is suggested that a standard electric drill on slow setting is used to drill the hole instead of a hammer drill to avoid breaking out the back of the hole when entering a void or cavity.

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

•Make sure that the wall will safely support four times the combined load of the equipment and all attached hardware and components.

Level and use wall plate as template to mark center

1 of holes. Drill two 5/16" (8 mm) dia. holes to a minimum depth of 2.5" (64 mm). Insert anchors (F) in holes flush with wall. Place wall arm assembly (AA) over anchor and secure with wood screws (D). Make sure wall arm is level, and tighten all fasteners.

WARNING

•Tighten screws so that wall plate is firmly attached, but do not overtighten. Overtightening can damage screws, greatly reducing their holding power.

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

CUTAWAY VIEW

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

•Never attach concrete expansion anchors to concrete covered with plaster, drywall, or other finishing material. If mounting to concrete surfaces covered with a finishing surface is unavoidable (not evaluated by UL), 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" (16 mm), custom fasteners must be supplied by installer (not evaluated by UL).
