Changing the Voltage
This pump comes with a dual voltage motor (115 V/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:
Motor must be grounded and motor ter
-
minal cover must be in place.
1. Disconnect the power supply to the pump.
2. Remove the cover from the motor terminal box.
3. Place the end of a flat screwdriver in the opening pro
-
vided and slide the voltage indicator to the right or left.
• To change from 115 V to 230 V, slide the indicator to
the right.
• To change from 230 V to 115 V, slide the indicator to
the left.
4. Reattach the motor terminal cover to the motor.
Wiring the Pump
1. Employ an electrician to do the wiring.
2. Use a properly protected circuit that is separate from
the distribution panel to the pump unit.
3. Install a properly fused disconnect switch in the line.
• Use the correct gauge of cable to carry the load.
IMPORTANT:
Undersized wire between the motor
and the power source will adversely limit the start
-
ing and load-carrying abilities of the motor.
4. Wire the connections.
• Connect the power lines to the pressure switch terminals marked L1 and L2.
• Very long leads will require a larger cable.
• For added safety, the pump and motor should be grounded to the well casing, if metal, or the
ground in the distribution panel.
5. For driven wells, water levels may be too low to pump at times. Have an electrician replace the pres
-
sure switch with a low pressure cut-off switch to prevent pump damage.
Risk of severe injury or death by electrical shock, or damage to system.
•
Always disconnect the electrical power before touching the pump.
•
A ground fault circuit interrupter (GFCI) is required.
•
If the power cord is damaged, it must only be replaced by qualified personnel.
