Installation to Solid Concrete or Cinder Block
1
Make sure that wall plate (
A
) is level, use it as a
template to mark two mounting holes. Drill two 1/4"
(6 mm) dia. holes to a minimum depth of 2.5" (64
mm). Insert anchors (
H
) in holes flush with wall as
shown (right). Place wall plate over anchors and
secure with two #14 x 2.5" screws (
G
). Level, then
tighten all fasteners.
• 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 wall will safely support four times the combined load of the equipment and all attached hardware
and components.

• Always attach concrete expansion anchors directly to
load-bearing concrete.
• Never attach concrete expansion anchors to concrete
covered with plaster, drywall, or other finishing mate-
rial. If mounting to concrete surfaces covered with a
finishing surface is unavoidable, the finishing surface
must be counterbored as shown below. Be sure
concrete anchors do not pull away from concrete
when tightening screws. If plaster/drywall is thicker
than 5/8", custom fasteners must be supplied by
installer.
WARNING
A
• Tighten screws so that wall plate is firmly attached,
but do not overtighten. Overtightening can damage
screws, greatly reducing their holding power.
• Never tighten in excess of 80 in. • lb (9 N.M.).
