6. Make sure the pre-charge pressure of the tank is 28 psi, as this pump's pre-charge pressure (or the
pressure at which the pump will start) is 30 psi.
• Unscrew the black valve cover located at the front of the tank.
• Use a tire pump or air compressor to charge the tank to 28 psi.
• Replace and tighten the plastic cap on the air valve.
• If a perma-pressure tank is not used, an air volume control should be used to maintain an air
cushion in the pressure tank. Refer to the pressure tank owner's manual.
7. Add unions and valves to allow system service without disabling the complete water supply.
Electrical Connections
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.
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 system.
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.
