Installation to Solid Concrete and Cinder Block WARNING • When installing Westinghouse 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 hardware and components. 1 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. Skip to step 2 on next page.

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.
