Step 1 - Check your single phase input voltage. The phase converter output voltage is based on the single phase input voltage. To lower the voltage on your generated phase, remove a run capacitor ( silver in color) from the circuit. Call Phoenix Phase Converters for assistance with this.
Step 2 - Check your single phase input voltage. The phase converter output voltage is based on the single phase input voltage. To raise the voltage on your generated phase, add more run capacitors (silver 50 MFD 220 Volts) to the circuit L1 and L3.
