Pump Installation and Wiring Diagram
1. Submersible ef flu ent turbine pumps may be installed in any
ap pli ca tion where relatively clear effl uent, such as from a dos ing
tank or high head STEP system etc., is being pumped.
2. Pumps should always be installed vertically. Pumps should
never be installed horizontally.
3. Because of their low temperature rise, pumps under 2 HP do
not require a fl ow inducer sleeve.
4. Mount the junction box in its permanent position.
5. Run prewired conduit, or equivalent submersible cable from
the junc tion box to a fused disconnect or, if applicable, the control
panel.
6. Feed the pump power cord and float switch cords into the
junc tion box.
7. Make the connections in the junction box using the wiring
di a grams below. If you are using a con trol panel or a fi ltered STEP
system, follow the wiring di a grams and in struc tions included with
them.
8. An alarm should be used with any system using a pump.
Follow the wiring diagram with the alarm for installation and check
your local codes.
9. Run the appropriate power to the control panel from a fused
(cir cuit breaker) disconnect. The appropriate power supply in for -
ma tion may be found on the pump nameplate.
10. To provide a suitable ground, a separate ground wire (green or
bare) at least as large as the line conductors is required. It is con-
nected from the electrical disconnect box to the con trol panel, to
the junction box and to the green ground wire of the submersible
motor lead.
11. Always disconnect all power when installing or ser vic ing the
pump.
