The ST-3050D submersible pump is factory set at 230 VAC. To change the voltage from 230 VAC to 460 VAC, perform the following:
1.Remove the four retaining screws that secure the power cord gland assembly to the pump casing, and pull the 230 VAC female plug (Figure 4) from the pump's cavity.
2.Un-plug the 230 VAC female plug from the male motor windings plug and insert the 460 VAC female plug into male motor windings plug.
3.Re-install the power cord gland assembly back into the pump's cavity. Make sure that the gland is seated correctly. This will prevent any connector pins from bending or breaking.
4.Insert the four retaining screws and tighten securely
