Wiring The Pressure Switch
1. Remove the switch Cover that installed the Pressure
Switch. (Fig. 1)
2. Insert an electrical wire strain relief into the opening
in the opposite side of the pressure switch (Fig. 2)
3. Pass the cable from the power supply through the
strain relief and tighten both screws on the strain relief. Do
not crush wire. (Fig .3)
4. Connect the two wires from the power supply to the
two outside terminals on the pressure switch (Fig. 4)
5. Connect the green ground wire from the power supply
to the green ground screw in the pressure switch (Fig. 5).
Risk of electric shock.
Can shock, burn or kill. Connect ground wire before connecting power supply wires. Use the
wire size (including the ground wire) specified in the wiring chart. If possible, connect the pump to a dedicated branch
circuit (one with no other appliances on it).
Risk of explosion.
Do not ground to a gas supply line.
WARNING: Risk of fire.
Incorrect voltage can cause a fire or seriously damage the motor and voids the warranty.
The supply voltage must be within ±10% of the motor nameplate voltage.
NOTE:
Motors voltage were set for 230 V. If necessary, reset the motor to the desired voltage, as shown. Install,
ground, wire, and maintain your pump in compliance with the National Electrical Code (NEC) or the Canadian
Electrical Code (CEC), as applicable, and with all local codes and ordinances that apply. Consult your local building
inspector for code information.
