Pump Installation and Wiring Diagram
1. Submersible turbine effluent pumps may be installed in any
application where relatively clear effluent, such as from a dosing
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 flow inducer sleeve.
4. Mount the junction box, if applicable, in its permanent position and
run prewired conduit, or equivalent submersible cable from the junction
box to a fused disconnect or, if applicable, the control panel.
5. Feed the pump power cord and float switch cords into the junction
box, or alternately to the panel if longer cords are used.
6. If a junction box is used, make the connections in the junction
box using the wiring diagrams below. If you are using a control
panel or a filtered STEP system, follow the wiring diagrams and
instructions included with them.
7. 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.
8. Run the appropriate power to the control panel from a fused (circuit
breaker) disconnect. The appropriate power supply information
may be found on the pump nameplate.
9. 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 control
panel, to the junction box and to the green ground wire of the
submersible motor lead.
10. Always disconnect all power when installing or servicing the pump.

Splicing Underground Wires
Splicing of wires to be buried must be done according to the National Electrical Code. Wire connectors or splicing
agents installed on conductors for direct burial shall be listed for such use.
