Place enclosure assembly (
A
) on wall and
mark center of four mounting holes. Drill
four 3/8" (10 mm) dia. pilot holes to a depth
of 3" (76 mm). Insert anchors (
B
) into holes
fl
ush with wall as shown (right). Insert two
screws (
C
), leaving a 1/2" gap between the
screw head and the wall, as shown in
fi
g.
2.8.

• 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 speci
fi
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 supporting surface will safely support the combined load of the equipment
and all attached hardware and components.
• 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).
