24 S&C Instruction Sheet 695-505
Installation
RTV silicone-rubber caulk
Bottom of
enclosure
Completing the Installation
STEP 1. A resilient closed-cell gasket on the bottom
ange of the enclosure protects the nish from
being scratched during installation and isolates
it from the alkalinity of a concrete foundation.
This gasket also helps to seal the enclosure; to
guard against entry of rodents, insects, and
weeds; and to discourage tampering.
In the event the gasket cannot compen-
sate for an uneven foundation, grout the
bottom of the enclosure as necessary. Any grout
applied should be recessed enough to permit
caulking. To complete the installation, caulk
around the bottom of the enclosure; a weather-
proof room-temperature vulcanizing (RTV)
silicone-rubber compound is recommended.
See Figure 25.
Apply a suitable compound to fill the spaces
between the cable and the conduit, and cap all
empty conduits to prevent the entry of moisture
and rodents.
STEP 2. Wipe down the exterior of the enclosure with a
clean, damp cloth. Re nish any scratches or
abrasions with S&C touch-up nish and red-
oxide primer, which are available in aerosol
spray cans. Order catalog number 999-080 for
light gray nish, 999-058 for olive green nish,
9991363-493 for seafoam green, 9991363-488 for
equipment green, and 9999-061 for red-oxide
primer. See Figure 26.
No other finish or primer is approved. The
area to be touched up should be cleaned to
remove all oil and grease. Sand the area to
remove any traces of rust that may be present,
and make sure all edges are feathered before
applying primer.
Figure 25. To complete the installation, caulk around the
bottom of the enclosure using a weather-proof, room-
temperature vulcanizing (RTV) silicone-rubber compound.
