Pump Installation and Wiring Diagram
1. Submersible
ef
fl u 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 fl oat 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
connected 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.
