Process B. Correctly Select Your
Pump
IMPORTANT: SELECT CORRECT
VOLTAGE
Disconnect pump from power source before changing the
pump voltage. To change the voltage, the selector switch is
located underneath the plastic access cover on top of the
motor. To access the switch, remove the eight screws holding
the plastic cover. To change the voltage setting, slide the
switch as shown until desired voltage is visible on the switch.
The voltage number that appears is the voltage setting for the
pump. Be sure the switch is completely engaged. Replace the
cover and secure it with the eight screws.
WIRING YOUR PUMP
Disconnect pump from power before servicing or handling
pump. Remove the cover from the pressure switch. Connect
the bare copper ground to the ground screw in the pressure
switch. Connect the power supply to the terminals marked

PIPING
Plastic PVC pipe is shown in the illustrations, but galvanized
steel pipe may be used if desired. All piping must be clean
and free of all foreign matter to prevent clogging. ALL JOINTS
AND CONNECTIONS IN THE WELL ASSEMBLY MUST
BE AIRTIGHT. Even a pinhole leak will prevent the proper
operation of the pump (this is the most common problem).
Use thread compound on all threaded joints unless specified
otherwise.
