1.1 Floor box must already be set in concrete
according to instructions furnished with oor box.

1.2

Remove temporary cover from 68-HP or 68-HP­CI oor box. Use a saw to cut top of box ush to
concrete oor surface (see Figure 2).

CAUTION

box opening to 7” diameter (see Figure 3).

1.4 Measure depth of oor box from nished oor to
bottom of the box. Use a saw to cut the voltage
divider so that when it is inserted in the oor box,
the top of the divider is 2-1/2” ±1/8” below the
nished oor surface (see Figures 4 and 5).

1.5
