1. Determine where the junction box will
be mounted on the riser. Mount the
junction box so the base of the en-
closure will be at grade once back-
filled as shown in Figure A.
NOTE: Bottom mounting to the 3/4”
terminal adapter may be preferred
in some instances as shown in
Figure B.
2. Access the riser by providing a 2 3/8”
access hole through the riser.
3. Place the 6” threaded conduit into the
terminal adapter that is already
installed in the junction box. Slip one
PVC washer over the conduit and
slide the conduit through the riser
wall as shown in Figure C.
4. After installation through the riser, slip
the 1/2” gasket and the second PVC
washer over the conduit. Determine if
the threads provided will be adequate
to tighten the assembly to the riser. If
threading is not adequate, remove the
assembly and shorten the conduit
until threading is adequate as shown
in Figure C. NOTE: The 1/2” gasket
should compress approximately
1/4” when lock nut is tightened.
5. Repeat steps 3 and 4 until desired
length is achieved. With PVC solvent,
weld the conduit into the terminal
adapter.
6. Mount the 3/4” terminal adapter to the
bottom of the junction box with the O-
ring and lock nut provided. A 1 1/16”
hole should be provided for the
adapter.
7. Mount the assembly through the riser
as described in steps 3 and 4. Using
the 2” lock nut, compress the gasket
and riser to secure the junction box.
8. Remove the backplate assembly from
the enclosure. Bring the wiring for the
pump power and alarm junction through
the 3/4” terminal adapter. Connect the
conductors for the pump to the terminal
block; connect N (neutral) to position 1,
and L1 (line) to position 2. Connect L2
to position 1 for 230 VAC installations.
NOTE: Overload protection, branch
circuit protection and main
disconnect provided by others.
Connect the conductors for the alarm
circuit to positions 3 and 4 as shown in
Figures C and D. Place the backplate
assembly back into the enclosure.
NOTE: If an alarm system is not
used, plug the third open position
in the cord seal with the PVC plug
provided.
9. Pass the piggy-back plug, pump plug
and alarm float cables through the 2”
conduit.
10. With the three position cord seal, route
the three cables through the seal,
leaving approximately 8” of cable to
work with. Insert the cord seal into the
panel terminal adapter and tighten the
hex nut until adequate strain relief is
achieved.
11. Gather all ground wires, including
grounding conductor on the cord seal,
and washer. Route and secure to
ground terminal as shown in Figures C
and D.
