2. Insert an electrical wire strain relief into the opening in the side of the pressure switch closest to the motor (Fig. 2).
3. Thread the cable from the pump motor through the strain relief into the pressure switch cavity and tighten both screws on the strain relief. Do not
crush wire (Fig. 3).
4. Connect the two motor wires of the motor cable to the two inside terminals on the pressure switch (Fig. 4).
5. Connect the green ground wire from the motor cable to one of the green ground screws at the bottom of the pressure switch (Fig. 5).

6. Insert an electrical wire strain relief into the opening in the opposite side of the pressure switch (Fig. 6).
7. Thread the cable from the power supply through the strain relief and tighten both screws on the strain relief. Do not crush wire (Fig. 7).
8. Connect the two wires from the power supply to the two outside terminals on the pressure switch (Fig. 8).
9. Connect the green ground wire from the power supply to the remaining green ground screw in the pressure switch and re-attach the
pressure switch cover (Fig. 9).

To change from 115V to 230V
10. The motor of this pump is dual voltage and can run on either 115V or 230V. In general, 230V is more economical to run, and requires a smaller
wire size. The 1/2 HP model is factory preset to run at 115V (Fig. 10).
NOTE: 1 HP models are factory preset to operate at 230V.
11. For 230V service, change the following wires on the terminal board:
a. Using a pair of needle nose pliers, pull the gray wire with the female flag connector from the “A” terminal spade post. Place it to the right
on the “B” terminal space post (Fig. 11a).
b. Pull the red wire with the female flag connector from the “L2” terminal. Place it to the left on the “B” terminal space post (Fig. 11b).
c. Reinstall the rear motor cover (Fig. 11c).
NOTE: To change 1 HP models to 115V, simply reverse instructions above.
