Suction Line
Suction Lift Applications
NOTE: The total suction lift should not exceed 25 feet.
1. Install a new, clean pipe or hose.
• Make sure piping rises vertically or is sloped continually upward from the water source to the
pump inlet connection.
• Check that there are no high spots that cannot be evacuated of air during the priming process.
2. Install a strainer at the end of the suction line.
• Ensure the strainer remains well submerged at all times.
Discharge Line
1. Tighten the discharge pipe, using an opposing pipe wrench on the pump discharge.
2. Install a check valve.
• All discharge piping must have a pressure rating capable of withstanding the incoming inlet
pressure plus the pump’s maximum shut-off head pressure.
IMPORTANT: Do not operate the pump under a no-flow/shut-off head condition.
Electrical Connections
Changing the Voltage
1 and 1.5 HP pumps come with dual voltage motors (115 V/230 V) and are 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 motor is grounded and motor terminal cover is in place.
1. Disconnect power to the pump.
2. Remove the cover from the motor terminal box.
1 HP Models
1. Insert a flat screwdriver into the black voltage change indicator.
2. Rotate the voltage change indicator so the desired voltage is
displayed.
• Twist the indicator counterclockwise to move from 230V to
115V.
• Twist clockwise to move from 115V to 230V.
3. Reassemble the terminal box cover.
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.
