Peerless Industries SA771PU manual Installation to Solid Concrete or Cinder Block

Installation to Solid Concrete or 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 supporting surface will safely support the combined load of the equipment and all attached hard- ware and components.

2	Determine and mark the desired display center on the
	wall. Place wall plate template (wall arm) on wall with

top mounting slots 9" (229 mm) above desired display center as shown in figure 2.1 on page 6. Level wall plate template (wall arm) on wall and mark center of four mounting holes making sure that the mounting holes. Drill four 3/8" (10 mm) dia. pilot holes to a depth of 3" (76 mm). Insert anchors (D) into holes flush with wall as shown (right). Place wall arm over anchors and secure with 5/16 x 3" screws (C). Level, then tighten all fasteners.

Place plate (A) over anchors (D) and secure with screws (C).

•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.).

•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).
