Installation to Concrete Ceilings or Concrete/Cinder Block Walls

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.
