Installation to Solid Concrete or Cinder Block WARNING • When installing Westinghouse 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. • 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 1/4" (6 mm) dia. holes to a minimum depth of 2.5" (64 mm). Insert anchors (H) in holes flush with wall as shown (right). Place wall plate over anchors and secure with two #14 x 2.5" screws (G). 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.). WARNING • 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", custom fasteners must be supplied by installer.
