115V

1. 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. 1/2 and 3/4 HP pumps are pre-set in the factory to run at 115V. (Fig. 1)

2. For 230V service, change the following wires on the terminal board:

PUMP PRIMING & STARTUP - PRIMING

CAUTION: All pumps must be primed (lling

the cavity with water) before they are rst operated.

This may take several gallons of water, as the

suction line will be lled in addition to the pump

cavity.
