Motor Switch Settings
NOTICE: 1/2 HP motors are dual voltage and are factory set to 115V. 3/4 & 1 HP motors are also dual voltage, but are
factory set to 230V. Motor terminal board (located under the motor end cover) should look like that shown below. Use
the instructions to set your motor to match your power source.
Never connect a motor set to 115V to a 230V power source.
