Star Water Systems Convertible Jet Pump Quick Start Guide - Manual (Page 2)

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.
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)
Pressure gauge
5. With pump operating at high pressure, open
two or more faucets and slowly unscrew
the flow control screw until maximum flow
is obtained. This steady pressure will be
minimum operating pressure and should agree
with the pressure shown below. The flow
control screw diverts the proper amount of
water to operate the ejector. ( Fig. 5)

The correct control valve setting will depend on the
type of well installation and pressure switch setting
for the particular pump.
NOTE: If the pump is being used for shallow well
applications, the flow control screw should be set in
the full open position.
IMPORTANT: If the pump fails to prime within
five minutes:
Turn power off at the breaker box. Look for leaks
or a milky color in the discharged water, which
indicates an air leak. Re-prime if necessary,
following steps 1 through 5 above. Reset breaker at
the breaker box. All connections must be water and
air tight in order for pump to operate.

1. Remove the 1/2 in.priming plug. ( Fig. 1)
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. Remove the 1/2 in. priming plug with pressure

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.
