Installation to Solid Concrete and Cinder Block
1
• When installing Westinghouse wall mounts on cinder block, verify that you have a minimum of 1-3/8" of actual con-
crete 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 specifica-
tions. 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.
WARNING
Remove cord 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.

• 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.

• 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.).
