or 230 V.
Pump is pre-set at the factory to run on 230 V.
1. To change pump voltage, remove the square
voltage switch cover at the top of pump and
move the voltage switch as shown.

PUMP PRIMING AND 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 pipe will be filled in
addition to the cavity of pump.
1. Remove pipe plug or pressure gauge (not
included) at the top of the discharge tee and
the vent plug in front of the discharge tee.

2. Slowly fill the discharge tee with water until
water overflows the vent plug opening.
Replace the vent plug loosely.
NOTE: It will take several minutes to fill pump
and suction pipe completely.
