Pressure Switch Assembly Instructions
WARNING: It is recommended all electrical work be
performed by a licensed electrician.
WARNING: When wiring from the power source to the
pressure switch, it is recommended that you use either a
14-gauge or 12-gauge cord.
WARNING: Before wiring the pressure switch, turn off
the power source to which you are connecting to avoid
potentially life threatening electrical shock.
To complete the installation, you must connect the power source to the pressure switch. A 30/50 Psi pressure switch has been installed on
the pump. The pressure switch allows for automatic operation; the pump starts when pressure drops to the "cut-in" setting (30 Psi pre-set).
To wire the pressure switch:
□ Remove the pressure switch cover on the pump to expose the wiring terminals.
□ Connect the green ground wire of the power supply to the switch ground terminal.
□ Connect the power supply wires to the two outside terminals marked "LINE" and replace the switch cover.
CAUTION: Do NOT use a pressure switch set at a pressure greater than 50 Psi. The pump will not create pressures greater than 50 Psi, if so
the pump will never shut off, resulting in damage to the pump and voiding the warranty.
