Permanently close all unused openings in this and
Disconnect power to control box before working
on or around control box, pipes, cable, pump,
or motor.
To be sure that starting relay will function and that
overload will not "nuisance trip", install control
box vertically with top side up.
Wire control box as shown in Diagrams.
Submersible pump will not operate without a
a jumper lead between 'SW' and 'L2' terminals.
Operation without control box will burn out the
pump motor.

do not remove or short circuit overload protection.
C hecking Procedure (All
Control Boxes):
Hazardous voltage. Can shock, burn,
or cause death. Disconnect power to control box
before doing these check procedures.

connections, etc.
3. Check for misconnections against diagram
in control box.
procedures that follow.
B. Ground (Insulation Resistance) Test. (Power to
control box disconnected)
2. Terminal Connections: One ohmmeter lead
touch other lead to each of the terminals
on terminal board.
3. Ohmmeter Reading: Pointer should remain
at infinity (∞) and not deflect.
C. Capacitor Tests. (Power to control
box disconnected)
Risk of electric shock. Short
capacitor across terminals before testing.
2. Terminal Connections: Connect ohmmeter
leads to black and orange wires out of
capacitor case.
3. Ohmmeter Reading: Pointer should swing
toward "zero" and "float" back to (∞).
Capacitor is shorted if pointer does not
move back to (∞), open if it does not move
from (∞).
4. To reset capacitor, reverse ohmmeter
connection to capacitor terminals.
D. Triac Test. (Solid state switch only)
2. Connect the leads to "R" (start) terminal
and to orange lead terminal on
start switch.
E. Coil Test. (Solid state switch only)
2. Connect leads to "Y" (common) and L2
terminal and to orange lead terminal on
start switch.
