Installation To Solid Concrete Or Cinder Block - PEERLESS EWMU Installation And Assembly Manual

Installation to Solid Concrete or Cinder Block

• When installing Peerless wall mounts on cinder block, verify that you have a minimum of 1-3/8" (35 mm) 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" (25 mm) minimum from the side of the block. Cinder block must meet ASTM
C-90 specifi cations. 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 four mounting holes. The top
mounting slots should be located 1.76" (45 mm)
above the desired screen center as shown in
fi gure 1.1 on page 4. Drill four 5/16" (8 mm) dia.
holes to a minimum depth of 2.5" (64 mm). Insert
anchors (E) in holes fl ush with wall as shown
(right). Place wall plate over anchors and secure
with #14 x 2.5" screws (D). Level, then tighten all
fasteners.
WARNING
• Tighten screws so that wall plate is fi rmly 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.).
• Always attach concrete expansion anchors directly
to load-bearing concrete.
• Never attach concrete expansion anchors to
concrete covered with plaster, drywall, or other
fi nishing material. If mounting to concrete surfaces
covered with a fi nishing surface is unavoidable (Not
evaluated by UL), the fi nishing 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" (16 mm), custom fasteners must be supplied
by installer (Not evaluated by UL).
