Step 6If the top of the floor box cover is to be flush with
the finished concrete floor, install the
concrete/terrazzo ring before the concrete pour.
(See installation instructions included with
concrete terrazzo ring kit.) If the finished floor
surface is to be terrazzo, install the trim ring after
the concrete pour.
Step 5Level box as required and anchor box to decking. To
level use 3/8-16 threaded rod cut to length as needed
and secure with hex nuts . (Threaded rod & nuts not
included). Holes for threaded rod are provided in
each end of the leveling legs attached to the bottom
of box. Be sure to set height of the top of the box to
be flush with the finished level of the concrete pour.
NOTE: There is no provision for post
pour box height adjustment.
Step 7Pour concrete flush with the top of floor box
protective cover.
WARNING: Pour concrete to within no more than 1/16"
[1.6mm] above box protective cover. Pours
of 1/4" [6.4mm] or more over box cover will
make it difficult to break out the cover and
cause excessive concrete spalling around
the edges of the box.

Step 9If the finished floor is to be terrazzo, remove the
rotective cover from the box, and install the
p
concrete/terrazzo trim ring kit. See instruction
sheet included with trim ring kit.
Step 10 Pull wires as specified, and terminate to
appropriate devices (not included).
NOTE: Make sure that each device is properly
grounded in accordance with the National
Electrical Code and any local code that
may apply.
