PUMP TO HOUSE CONNECTION (DISCHARGE PIPE) PUMP ELECTRICAL CONNECTIONS
WARNING:
• Always disconnect pump from electricity before performing any work on the motor.
• Under-sized wiring can cause motor failure and even fire. Use proper wire size specified in the
Wire Size Chart.
• Replace damaged or worn wiring cord
immediately.
• Do not kink power cable and never allow the
cable to come in contact with oil, grease, hot
surfaces, or chemicals.
• The pump must be properly grounded using
the proper wire cable with ground.
CAUTION:
• Protect the power cable from coming in
contact with sharp objects.
• All wiring should be performed by a qualified
electrician in accordance with the National
Electric Code and local electric codes.
• Connect the pump to a separate electrical
circuit with a dedicated circuit breaker. Refer
to the Wire Size Chart for proper fuse size.

5. IMPORTANT: Air pressure in the tank
must be 2 PSI lower than the “cut-in” of the
pressure switch. Pump/tank has a 20/40
PSI pressure switch, so tank pressure must
be set at 18 PSI. Locate the air valve/stem
on the tank and check pressure with a tire
gauge (not included). If air needs to be
removed, press down on valve to bleed air
off. Use a tire pump or air compressor to
add air if needed.

CAUTION: Make certain that the power source
matches the pump requirements. This pump has
a dual voltage motor and can run on 115 V or
230 V.
Pump/tank is pre-set at the factory to run on
230 V.
1. To change pump voltage, remove the square
voltage switch cover at the top of pump/tank
and move the voltage switch as shown.
