WARNING • When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" of actual concrete surface 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. For Concrete Walls drill one 1/4" (6 mm) dia. hole to a minimum depth of 2" (51 mm). Insert anchor (E) in hole flush with wall as shown (right). Place wall bracket, with slot on tube facing down, over anchor (E) and secure with #14 x 2" wood screw (D). Make sure wall bracket is level, mark other hole and repeat steps with other fasteners. Tighten all fasteners. IMPORTANT: Make sure wall bracket is level on wall. WARNING • Tighten concrete anchor bolts firmly, but do not overtighten. Overtightening can damage the bolts, greatly reducing their holding power. • Never tighten in excess of 80 in • lb (9 N.M.). WARNING • Concrete anchors are not intended for attachment to concrete wall covered with a layer of plaster, drywall, or other finishing material. If mounting to concrete wall covered with plaster/drywall is unavoidable, plaster/ drywall (up to 5/8" thick) must be counterbored as shown below. If plaster/drywall is thicker than 5/8", custom fasteners must be supplied by installer.
