Peerless Industries SUF640P 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" 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 specifica- tions. 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 at- tached hardware and components.

Make sure that wall plate (A) is level, use it as

1 a template to mark two mounting holes. The top mounting slots should be located 7" (177 mm) above the desired screen center as shown in figure 1.1 on page 4. Drill four 5/16" (8 mm) dia. holes to a minimum depth of 2.5" (64 mm). Insert anchors (D) in holes flush with wall as shown (right). Place wall plate over anchors and secure with two wood screws (C). 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.).

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

•Never attach concrete 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", custom fasteners must be supplied by installer (not evaluated by UL).
