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" 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" 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.

•Installer must verify that the supporting surface will safely support the combined load of the equipment and all attached hardware and components.

3	Make sure that wall plate (F) is level, use it as a					solid
	template to mark the two center mounting holes. Drill				K		concrete
	two 1/4" (6 mm) dia. holes to a minimum depth of 2.5"							cinder
	(64 mm). Insert anchors (K) in holes flush with wall as				F				block
	shown. Place wall plate over anchors and secure with
	#14 x 2.5" screws (J). Level, then tighten all fasteners.
	WARNING				J
•	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.).
	WARNING				1				concrete
									surface
•	Always attach concrete anchors directly to load-								K
	bearing concrete.
• Never attach concrete anchors to concrete covered
	with plaster, drywall, or other finishing material. If				Drill holes and insert anchors (K).
	mounting to concrete surfaces covered with a finishing				2		F
	surface is unavoidable, the finishing surface must be
	counterbored as shown below. Be sure concrete
	anchors do not pull away from concrete when tighten-
	ing screws. If plaster/drywall is thicker than 5/8",						J		K
	custom fasteners must be supplied by installer.
	INCORRECT		CORRECT		Place plate (F) over anchors (K) and secure with screws (J).
