Installation to Concrete Ceilings or Concrete/Cinder Block Walls
• Always attach concrete expansion anchors directly
to load-bearing concrete.
• Never attach concrete expansion anchors to con-
crete covered with plaster, drywall, or other fi nishing
material. If mounting to concrete surfaces covered
with a fi nishing surface is unavoidable, the fi nishing
surface must be counterbored as shown below. Be
sure concrete anchors do not pull away from con-
crete when tightening screws. If plaster/drywall is
thicker than 5/8" (16 mm), custom fasteners must be
supplied by installer (not UL approved).
WARNING
NOTE: Wall installation with models EXC, EXC-S
and EXC-W is not available.
Place ceiling/wall plate (A) on ceiling or wall as a
template. Note: Place ceiling/wall plate according
to position of opening in outer channel (B) as shown
in fi gure 2.4. or fi gure 2.5. Drill two 1/4" (6 mm) dia.
holes to a minimum depth of 2.5" (64 mm). Attach
ceiling/wall plate (A) using two concrete anchors (J),
two #14 x 2.5" wood screws (H) and two washers (O)
as shown in fi gure 2.6. Tighten wood screws (H) until
ceiling/wall plate (A) is fi rmly attached.

• Tighten wood screws fi rmly, but do not overtighten.
Overtightening can damage the screws, greatly
reducing their holding power.
• Never tighten in excess of 80 in • lb (9 N.M.).

• When installing Peerless 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 specifi ca-
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.
• Installer must verify that the supporting surface will safely support the combined load of the equipment and all at-
tached hardware and components.
