PUMP PRIMING & STARTUP - PRIMING
CAUTION: All pumps must be primed (filling
the cavity with water) before they are first operated.
This may take several gallons of water, as the
suction line will be filled in addition to the pump
cavity.
4. Thread in priming plug and then open optional
ball valve if installed (see page 5) by turning
handle to line up with the pipe. (Fig. 4)
2. Slowly fill pump cavity until water comes out of
air relief hole on top of the pump. ( Fig. 2)
3. Replace air relief plug and continue adding
water to pump cavity until water reaches the
top of the priming plug. (Fig. 3)

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:
