Installation To Concrete Ceilings - PEERLESS Paramount PC930A Installation Et Montage

Installation to Concrete Ceilings

• 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.
Place ceiling plate (A) on ceiling as a template and
2
mark the center of the two mounting holes.
Note: Opening in outer channel indicates the front of
the mount.
Drill two 1/4" (6 mm) dia. holes to a minimum depth
of 2.5" (64 mm). Attach ceiling plate (A) using two
concrete anchors (I) and two #14 x 2.5" wood
screws (H) as shown in figure 1.3 and figure 1.4.
Tighten wood screws (H) until ceiling plate (A) is
firmly attached.
WARNING
• Tighten wood screws firmly, 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.).
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" (16 mm), custom fasteners must be sup-
plied by installer (not UL approved).
