Installation To Solid Concrete And Cinder Block - PEERLESS SA740P Installation And Assembly Manual

Installation to Solid Concrete and Cinder Block

• 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.
• Make sure that the supporting surface will safely support the combined load of the equipment and all attached hard-
ware and components.
Remove cord covers from wall arm assembly (A) as
1
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.

WARNING
• Tighten screws so that wall plate is firmly attached,
but do not overtighten. Overtightening can damage the
screws, 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 as shown below. If mounting
to concrete wall covered with plaster/drywall is
unavoidable, plaster/drywall (up to 5/8" thick) must be
counterbored as shown below. Be sure concrete
anchors do not pull away from concrete when tighten-
ing screws. If plaster/drywall is thicker than
5/8", custom fasteners must be supplied by installer.
