Changing the Voltage
This pump comes with a dual voltage motor (115/230 V)
and is factory set for 230 V. Ensure the voltage indicator
matches the voltage at the power source. Do not connect
to voltage other than that shown.
IMPORTANT: Ensure the motor is grounded and the
motor terminal cover is in place.
1.
Disconnect the power supply to the pump.
2. Remove the cover from the motor terminal box.
3. To change the voltage to 115V, pull and rotate the dual voltage switch and set to
"Low V" from the "High V" factory setting.
4. To change the voltage on other models, press the black
voltage change device onto both terminals with the
white arrow directly aligned with the correct voltage on
the terminal board.
IMPORTANT: Do not move the white lead wires on L1
and L2.
5. Reassemble the terminal box cover.
Wiring the Pump
IMPORTANT: Employ an electrician to do the wiring.
1. Disconnect power at electrical panel before making any electrical connections.
IMPORTANT: Supply voltage must be +/- 10% of motor nameplate voltage. Low or high voltage
can damage the motor and will void the warranty.
2. Provide a separate circuit from the distribution panel to the pump unit.
3. Install a proper fused disconnect switch in the line, making sure the cable is the correct gauge to
carry the load.
• Very long runs will require a larger cable size to minimize voltage drop.
• A fuse or circuit breaker is for short-circuit protection only and does not serve as overload pro-
tection for the motor.
4. Remove the cover from the pressure switch.
5. Connect the incoming power wires to the LINE terminals and the insulated green or bare wire
securely to the ground screw.
IMPORTANT: The ground wire must be connected to the electrical system ground (provided by
the power company) or another adequate ground. Do not operate pump unless it is grounded.
