Installation to Solid Concrete and Cinder Block
1
• 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 meetASTM 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
breakingoutthe back of the hole when entering avoidor cavity.
• Concrete must be 2000 psi density minimum. Lighter density concrete may not hold concrete anchor.
• Makesure that the supporting surface will safely support thecombined load of the equipment and all attached hard-
wareand components.
WARNING
Removecord covers from wall arm assembly (A)as
shown in figure 1.1. Level and use wall plate as
template to mark center of holes. Drill two 1/4" (6
mm) dia. hole to a minimum depth of 2" (51 mm).
Insert anchors (B) in holes flush with wall as shown
in fig 1.3. Place wall mount (A) over anchor and
secure with wood screw (H) as shown in figures 1.4
and 1.6. Make sure wall mount is level, and tighten
all fasteners. See figure 1.5.
