Cased Well Installation
Connect a foot valve to the first length of suction pipe,
and lower the pipe into the well. Add sections of piping
as needed, use pipe joint compound at the joints.
Lower the foot valve at least 5 feet beneath the lowest
draw down water level, but not too close to the bottom
of the well. Sediment may clog the strainer if it is too
close to the bottom.
Fill pipes with water to check foot valve for leakage.
When the proper depth is reached, install a sanitary
well seal over the pipe and into the casing. Tighten
down the bolts to make the seal.
Add a tee to the pipe with a plug on the top for priming
at the highest point at pump. Connect horizontal piping
to the pump, making sure the pipe slopes slightly and
gradually up to the pump. This prevents air pockets in
the system. For horizontal offsets in excess of 20 feet,
increase the pipe size in accordance with Table I.
Point Driven Installation
Install a packer-type foot valve in the driven pipe below
the lowest draw down level of the water.
Be sure that the packer-type foot valve is
not inserted so far that it enters the well point, as it
would not restrict flow of water back down the well.
Instructions are included with the foot valve. Fill the ver-
tical pipe with water to be sure that the foot valve does
not leak.
Add a tee to the driven pipe and run the pipe horizon-
tally to the pump, making sure that it slopes gradually
up to the pump to avoid air traps. For long horizontal
offsets, increase the pipe size according to the size
specified in Table I. The tee is to include a priming plug.
Dug Well or Lake Installation
Install a foot valve on the suction pipe and lower it into
the well. Be sure the foot valve does not rest on the bot-
tom of the well, as it will clog with sand and stones. Fill
the vertical pipe with water to be sure the foot valve
does not leak.
Add a tee with a priming plug, to the vertical pipe and
install a pipe horizontally to the pump. make sure the
pipe slopes gradually up to the pump to avoid air traps.
For long offset installations increase the pipe size
according to the size specified in Table I.
When a lake is the source supply, the pipe should be
installed far enough into the lake to have it submerged
at all times. The end of the suction pipe should be pro-
tected with a strainer crib, with a check valve installed
in the horizontal line. Make sure that all pipes installed
into the lake are protected against freezing or drained
under frost conditions.

PUMP INSTALLATION
Install the pump as shown in Figures 1 or 2. It is impor-
tant that a foot valve be used, or that a check valve be
installed in the horizontal line as near the pump as pos-
sible. A 4” long nipple should be installed in the 1” suc-
tion tapping of the pump. If pump is tank mounted, the
pump discharge is already piped to the tank, and is
ready to be piped to the house service. A base mount-
ed pump can be connected to a vertical tank by means
of a pump-to-tank fittings kit (available from your deal-
er) and necessary piping. A gate valve should be
installed in the line between the pump and tank.
Relief valve must be capable of passing full pump flow
at 75 PSI.
Horizontal Piping
In a horizontal offset installation, elbows and horizontal
piping must be added to complete installation. Be sure
to pitch the pipe up to the pump from the well, in order
to avoid air pockets. When all piping is correctly posi-
tioned, tighten the bolts in the well seal, making sure
the well seal is firmly seated in the casing.
Run the suction piping direct from the jet to the well. If
the suction line has a long horizontal run – (50 ft.) a foot
valve is necessary. A tee with a plug near the pump is
desirable to fill the suction line for the initial prime.
Pressure Tanks and Piping
Several types of tank installations can be used with this
pump. In the case of an assembled water system, the
pump is mounted on a pressure tank, and only requires
connection to the house piping. All connections
between the pump and tank are made at the factory.
The tank serves two functions. It provides a reservoir of
water, some of which can be drawn through the house
fixture before the pump must start, and it maintains a
cushion of air under pressure.
When a horizontal tank is used, an air volume control
adds air to the tank when it is needed. See instructions
included with Air Volume Control for details on installa-
tion and operation.
When Sta-Rite Con-Aire®tanks are used, no air volume
control is necessary. This tank contains a permanent
precharge of air.

Standard Horizontal Tanks
The pump can be foot mounted and connected to a
standard tank, using standard pipe fittings. The tank
should be set on tank feet or another type of support to
minimize corrosion under the tank caused by conden-
sation. A gate valve and union should be installed
between the pump and tank to make the pump easily
removable for service. The air volume control should be
installed in the tapping provided on the side of the tank.
Connect the air volume control tubing to the pump with
the fittings furnished. A gate valve should be installed
between the tank and the house service piping.
Atmospheric Charging –
Horizontal Tanks Only
Atmospheric charging is used when additional air in the
tank is not required to supply a sufficient amount of
water between pump cycles. It is accomplished by
operating the pump through one complete cycle to see
if everything functions properly. Drain the tank by
removing the lower pipe plug. Replace the plug and
start the pump. An atmospheric charge of air remains in
the tank, and gives a minimum cushion necessary for
normal domestic operation.
PRIMING THE PUMP
Never run pump dry. Running pump with-
out water may cause pump to overheat, damaging seal
and possibly causing burns to persons handling pump.
Fill pump with water before starting.
Never run pump against closed dis-
charge. To do so can boil water inside pump, causing
hazardous pressure in unit, risk of explosion and possi-
bly scalding persons handling pump.
Models thru 3/4 HP (ANB, ANC, AND)
Remove the priming plug (Key No. 10, Figure 5, Page
8), and fill the pump with water. The 4” vertical nipple
installed in the suction tapping enables you to com-
pletely fill the pump body with water, when no line
check valve is used. This is essential for the initial
prime. Replace priming plug and start pump. Water
should be pumped in a few minutes, depending upon
the depth to water and the horizontal run of piping. If
pump does not prime after a few minutes of running,
repeat the priming process, until all the air is evacuat-
ed from the pump and piping. Once the pump is in
operation, further priming will not be necessary.
Models ANE, ANF (1 HP – 1-1/2 HP)
Remove the priming plug (Key No. 10, Figure 6, Page
9), fill the pump with water. Replace plug, and start
pump. Water should be pumped in a few minutes,
depending upon the horizontal run of pipe and depth to
water. Once the pump is in operation, further priming
will not be necessary.

ELECTRICAL
Disconnect power at service panel be-
fore connecting pressure switch.
Figure 3 - 115/230 volt motor wiring con-
nections through typical pressure switch.
Dual voltage motors come factory wired for 230 volt
operation. Inset shows 115 Volt conversion.
Do not alter wiring in single voltage motors.
Match motor voltage to power supply voltage.
Risk of serious or
fatal electrical shock.
Connect motor ground
wire before connecting
power
supply wires.
Do not ground to a gas
supply line.
Turn off power before
working on pump or
motor.
Match motor voltage and power supply voltage.
Supply voltage must be within ±10% of motor nameplate
voltage. Incorrect voltage can cause fire or seriously
damage motor and voids warranty. If in doubt, consult a
licensed electrician.
Use wire size specified in wiring chart. If possible,
connect pump to a separate branch circuit with no other
appliances on it.
1. Install, ground, wire and maintain pump in accor-
dance with your local electrical code and all other
codes/ordinances that apply. Consult your local
building inspector for code information.
2. Connect ground wire first as shown at left. Ground
wire must be a solid copper wire at least as large as
power supply wires.
•There must be a solid metal connection between
pressure switch and motor to provide motor ground-
ing protection. If pressure switch is not connected to
the motor, connect ground screw in switch to motor
ground screw. Use a solid copper wire at least as
large as power supply wires.
•Connect ground wire to grounded lead in service
panel, metal underground water pipe, well casing
at least 10’ (3M) long, or to ground electrode pro-
vided by power company.
3. Connect power supply wires as shown at left.
4. Replace pressure switch cover before turning on
power to pump.
Motor normally operates at high tem-
perature and will be too hot to touch. It is protected
from heat damage during operation by an automatic
internal cutoff switch. Before handling pump or motor,
stop motor and allow it to cool for 20 minutes.

PUMP SERVICE
Complete pump and piping system must
be protected against below freezing temperature.
Failure to do so could cause severe damage and voids
warranty.
Lubrication
It is not necessary to lubricate the jet pump or its motor.
The motor has two shielded ball bearings, that are lubri-
cated for the life of the bearing. The mechanical shaft
seal in the pump is self-lubricating.
The Shaft Seal
The seal consists of primarily two parts; a rotating half
and a ceramic seat.
The highly polished and lapped faces of
the seal are easily damaged. Read the instructions
thoroughly and handle the seal with care.
Piping to well and tank need not be disturbed to service
pump, motor, or to replace seal.
1. Disconnect electric service (pull switch), and dis-
connect wiring to pump.
2. Remove capscrews holding motor to pump body.
Motor with impeller and diffuser can now be
removed.
3. Carefully tap diffuser to remove from seal plate.
Removal of Old Seal
1. After unscrewing impeller, carefully remove rotating
part of seal by prying up on sealing washer, using
two screwdrivers (see Figure 4A). Use care not to
scratch motor shaft.
2. Remove seal plate from motor and place on flat sur-
face, face down. Use a screwdriver to push ceramic
seat out from seal cavity (see Figure 4B).
Installation of Floating Seat (Figure 4C)
1. Clean polished surface of floating seat with clean
cloth.
2. Turn seal plate over so seal cavity is up, clean cavi-
ty thoroughly.
3. Lubricate outside rubber surface of ceramic seat
with soapy water and press firmly into seal cavity
with finger pressure. If seat will not locate properly in
this manner, place cardboard washer over polished
face of seat and press into seal cavity using a 3/4”
socket or 3/4” piece of standard pipe.
4. DISPOSE OF CARDBOARD WASHER. Be sure
polished surface of seat is free of dirt and has not
been damaged by insertion. Remove excess soapy
water.
Installation of Rotating Part
of Seal Unit (Figure 4D)
1. Reinstall seal plate using extreme caution not to hit
ceramic portion of seal on motor shaft.
2. Inspect shaft to make sure that it is clean.
3. Clean face of sealing washer with clean cloth.
4. Lubricate inside diameter and outer face of rubber
drive ring with soapy water and slide assembly on
motor shaft (sealing face first) until rubber drive ring
hits shaft shoulder.
5. Screw impeller on shaft until impeller hub hits shaft
shoulder. This will automatically locate seal in place
and move the sealing washer face up against seat
facing. Reinstall impeller screw (if used).
