ELECTRICAL CONNECTIONS

To change from 115V to 230V
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:
a. Using a pair of needle nose pliers, pull the
gray wire with the female ag connector
from the “A” terminal spade post. Place it
to the right on the “B” terminal space post.
(Fig. 2a)
230V
b. Pull the red wire with the female ag
connector from the “L2” terminal. Place it to
the left on the “B” terminal space post.

PRIMING
6
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.
Deep Well Application Only:
Pressure gauge
HP Pressure Setting
1/3
1/2
3/4
1
The correct control valve setting will depend on the
type of well installation and pressure switch setting
for the particular pump.
Shallow Well Application Only
24 PSI
27 PSI
38 PSI
46 PSI
NOTE: If the pump is being used for shallow well
applications, the ow control screw should be set in
the full open position.
IMPORTANT: If the pump fails to prime within
ve 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)
2. Fill pump cavity with water until full and replace
priming plug. (Fig. 2)
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 lled several times in order to
achieve the prime. (Fig. 4)
Priming plug

gauge
Air relief plug
1. Remove the 1/2 in. priming plug with pressure
gauge and air relief plug. (Fig. 1)
Water
level in
pump
cavity
3. Replace air relief plug and continue adding
water to pump cavity until water reaches the
top of the priming plug. (Fig. 3)
3. Tighten ow control screw completely by turning
clockwise, then loosen two turns. Now start the
pump. (Fig. 3)
5. With pump operating at high pressure, open
two or more faucets and slowly unscrew
the ow control screw until maximum ow
is obtained. This steady pressure will be
minimum operating pressure and should agree
with the pressure shown below. The ow
control screw diverts the proper amount of
water to operate the ejector. (Fig. 5)
2. Slowly ll pump cavity until water comes out of
air relief hole on top of the pump. (Fig. 2)
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.
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)
5. Turn on breaker to start pump
