1. Orient the preset insert so the prepunched rivet hole in
the cellular raceway aligns with the rivet hole cast
into preset.
2. Hook the preset insert into the end of the prepunched
data access openings in the cellular raceway utilizing its
two offset flanges.
3. Slide the preset into position toward the hooked end
until the preset insert rivet hole is aligned with the rivet
hole in the cellular raceway and install a 16" [4.8 mm]
diameter steel pop-rivet with a 1/8" [3.2 mm] grip
range (by others).
4. Caulk around preset if necessary and install mudcap
if shipped separately.
5. Final Inspection: A final inspection of all inserts must
be made by the electrical contractor just prior to
concrete placement. Any damaged preset inserts
must be replaced.
CAUTION: The concrete shall be thoroughly worked by the
most practical means, such as tamping or vibrating adjacent
to the sides of the preset insert. The electrical contractor
should assure that this is done during the pour and finishing
of the concrete floor.
6. Fire Classification – Walkerdeck Only: Refer to the
Underwriters’ Laboratories, Inc., Fire Resistance
Directory for information on fireproofing requirements
for the particular Fire Resistance Design Classification
that is required. The Fire Resistance Directory also
specifies the maximum number of presets, spacing
and locations.
