Installation to Solid Concrete or Cinder Block
• 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.
Make sure that wall plate (A) is level, use it as a
1
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.
WARNING
• 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.).
WARNING
• 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.
