Peerless Industries PP740-S instruction

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 supporting surface will safely support the combined load of the equipment and all attached hardware and components.

2	Level and use wall plate as template to mark center
	of holes. Drill two 5/16" (8 mm) dia. holes to a

minimum depth of 2.5" (64 mm). Insert anchors (B) in holes ﬂush with wall. Place wall mount (A) over anchors and secure with wood screws (H). Make sure wall mount 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.).
•	Always attach concrete expansion anchors directly to
