Peerless Industries PF630 manual Installation to Solid Concrete or Cinder Block, Evaluated by UL

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

1	Make sure that wall plate (A) is level, use it as a
	template to mark two mounting holes. Drill two 5/16"

(8 mm) dia. holes to a minimum depth of 2.5"

(64 mm). Insert anchors (E) in holes flush with wall as shown. Place wall plate over anchors and secure with two #14 x 2.5" screws (D). Level, then 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.).

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

•	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,
	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).
