PUMP PRIMING & STARTUP
Shallow Well Application Only
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.
1. Remove the 1/2 in. priming plug with pressure gauge and air relief plug (Fig. 1).
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).
4. Check to be sure water in pump cavity stays constant. If water level goes down, it could indicate a
leak in the foot valve, check valve or suction pipe.
5. Thread in priming plug and then open optional ball valve if installed by turning handle to line up with
the pipe (Fig. 4).
6. Turn on breaker to start pump.
IMPORTANT: If the pump hums instead of pumping or turns off repeatedly, shut pump off immediately. Check voltage. Make sure your
incoming voltage matches the pump wiring voltage. See wiring guide in the instructions.
NOTE: Watch for leaks or a milky color in the discharged water, which indicates an air leak. Make sure foot valve and/or check valve is working properly.

Deep Well Application Only
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.
1. Remove the 1/2” priming plug (Fig. 1).
2. Fill pump cavity with water until full and replace priming plug (Fig. 2).
3. Tighten flow control screw completely by turning clockwise, then loosen two turns. Now start
the pump (Fig. 3).
4. If pump is properly primed, pressure will quickly build and register on the gauge mounted directly
on the pump body. If pressure does not build repeat priming operation. All air must be vented
from the drive and suction pipes as well as the body before the pump will prime. The pump body
may need to be filled several times in order to achieve the prime (Fig. 4).
