Watertight Junction Box Wiring
The preferred location of the junction box is inside the riser. Some
codes require the junction box to be outside the riser. Check with your
local health department and electrical inspector before deciding upon
the location.
• Junction boxes must be watertight. All wiring that passes through
the wall of the box must use watertight connectors and be sealed
properly.
• NOTE: See CL0625B for a list of suggested junction boxes and
CL0620B for prewired conduit assemblies. Junction boxes for the
high head filter system are fully assembled and are provided with a
3/4” PVC conduit attachment and the appropriate number of cord
seals for the pump and floats.
• For junction boxes that are not fully assembled or predrilled, drill
a 1-1/8” hole in the box for the 3/4” PVC conduit fitting. Install with
washer on the outside of box. Silicone is recommended around the
opening for the best seal. Drill a 7/8” hole in the box for each cord
seal. Install with washer on the outside of box. Silicone is recom-
mended around each opening for the best seal.
Startup
Before placing the equipment into operation the following must be
checked:
• Septic tank or pump chamber should be pumped and cleaned prior
to installation in existing system.
• Septic tank or pump chamber must be watertight.
• Installation needs to be according to instructions.
• Installation should include an easy access riser and tamper
resistant lid.
• Filter assembly needs to be in place and secure.
• Float tree needs to be in place, secure and adjusted for
proper cycling.
• Make sure float switches are free to move within the basin.
• Be sure electrical connections are watertight and
conform to the Uniform Building Code and the National Electrical
Code (NEC).
• Fill the septic tank with water and check the system for operation.
After installing the pump into the containment area with adequate
submergence, open the discharge valve fully. Start the unit using manual
controls. If flow is appreciably less than rated performance, pump may
be air locked. To expel trapped air, jog the unit several times, using
the manual controls. If your system has a check valve, make sure the
weep hole is clear.
Check float levels during operation and adjust accordingly as
needed.
Have a qualified electrician take voltage and current measurements
on the black wire of single phase. Record these readings in the space
provided in the “Owner’s Information” section on the front this manual
for future reference.
Be sure to complete all items such as installing the lid on the riser,
securely closing the control panel, and checking the system operation
have been completed before placing the system into service.
