REPLACING AN OLD PUMP
Hazardous voltage. Disconnect power to
pump before working on pump or motor.
Step 1. Drain and remove the old pump. Check the old
pipe for scale, lime, rust, etc., and replace it if
necessary.
Step 2. Install the pump in the system. Make sure that all
pipe joints in the suction pipe are air-tight as well
as water tight.
If the suction pipe can suck air, the
pump will not be able to pull water from the well.
Step 3. Adjust the pump mounting height so that the
plumbing connections do not put a strain on the
pump body. Support the pipe so that the pump
body does not take the weight of piping or fittings.
You have just completed the well plumbing for
your new shallow well jet pump. Please go to
Page 6 for discharge pipe and tank connections.
WELL POINT (DRIVEN POINT)
INSTALLATION (Figure 1)
Step 1. Drive the well, using “drive couplings” and a
“drive cap”. “Drive fittings” are threaded all the
way through and allow the pipe ends to butt
against each other so that the driving force of the
maul is carried by the pipe and not by the
threads. The ordinary fittings found in hardware
stores are not threaded all the way through the
fitting and can collapse under impact. “Drive fit-
tings” are also smoother than standard plumbing
fittings, making ground penetration easier.
Step 2. Mount the pump as close to the well as possible
Step 3. Use the fewest possible fittings (especially elbows)
when connecting the pipe from the well point to the
pump suction port. The suction pipe should be at
least as large as the suction port on the pump
(include a check valve if your pump is not equipped
with one – see Figure 1). Support the pipe so that
there are no dips or sags in the pipe, so it doesn’t
strain the pump body, and so that it slopes slightly
upward from the well to the pump (high spots can
cause air pockets which can air lock the pump). Seal
the suction pipe joints with teflon tape or a teflon
based pipe joint compound. Joints must be air- and
water-tight. If the suction pipe can suck air, the
pump cannot pull water from the well. If one well
point does not supply enough water, consider con-
necting two or three well points to one suction pipe.
You have just completed the suction piping for
your new shallow well jet pump. Please go to
Page 6 for discharge pipe and tank connections
CASED WELL INSTALLATION, 2" OR
LARGER CASING (Figure 2)
Step 1. Mount the pump as close to the well as possible.
Step 2. Assemble the foot valve, strainer, and well pipe
(see Figure 2). Make sure that the foot valve
works freely.
Step 3. Lower the pipe into the well until the strainer is five
feet above the bottom of the well. It should also be
at least 10 feet below the well’s water level while
the pump is running in order to prevent the pump
from sucking air. Install a sanitary well seal.

Step 4. Install a priming tee, priming plug, and suction
pipe to the pump (see Figure 2). Connect the pipe
from the well to the pump suction port, using the
fewest possible fittings – especially elbows – as
fittings increase friction in the pipe (however,
include a foot valve – see Figure 2). The suction
pipe should be at least as large as the suction
port on the pump. Use teflon tape or a teflon-
based pipe joint compound on threaded pipe
joints. Support the pipe so that there are no dips
or sags in the pipe, so it doesn’t strain the pump
body, and so that it slopes slightly upward from
the well to the pump (high spots can cause air
pockets which can air lock the pump). Seal the
suction pipe joints with teflon tape or a teflon
based pipe joint compound. Joints must be air-
and water-tight. If the suction pipe can suck air,
the pump cannot pull water from the well.
You have just completed the suction piping for
your new shallow well jet pump. Please go to
Page 6 for discharge pipe and tank connections.
INSTALLATION FOR SURFACE WATER
(Figure 3)
Step 1. The pump should be installed as close to the
water as possible, with the fewest possible fittings
(especially elbows) in the suction pipe. The suc-
tion pipe should be at least as large as the suction
port on the pump.
Step 2. Assemble a foot valve and suction pipe (see
Figure 3). Make sure that the foot valve works
freely. Use teflon tape or a teflon-based pipe joint
compound on threaded pipe joints. Protect the
foot valve assembly from fish, trash, etc, by
installing a screen around it (see Figure 3).
Step 3. Lower the pipe into the water until the strainer is
five feet above the bottom. It should also be at
least 10 feet below the water level in order to
prevent the pump from sucking air.
Step 4. Install a priming tee, priming plug, and suction
pipe to the pump (see Figure 3). Support the pipe
so that there are no dips or sags in the pipe, so it
doesn’t strain the pump body, and so that it
slopes slightly upward from the well to the pump
(high spots can cause air pockets which can air
lock the pump). Seal the suction pipe joints with
teflon tape or a teflon based pipe joint com-
pound. Joints must be air- and water-tight. If the
suction pipe can suck air, the pump cannot pull
water from the well.

Discharge Pipe and Pressure Tank Connections 6
PRE-CHARGE TANK CONNECTION
(Figure 4)
Step 1. Install two tees in the pump discharge port (see
Figure 4). The pipe size must be at least as large
as the discharge port.
Step 2. Run a pipe or reinforced hose from one arm of
the first tee to the port on the pre-charged tank.
Step 3. Connect the other end of the discharge tee to
your plumbing system.
Step 4. Check the pre-charge of air in the tank with an
ordinary tire gauge. The pre-charge should be 2
PSI less than the cut-in setting of the pump’s pres-
sure switch. The pre-charge is measured when
there is no water pressure in the tank. Your new
pump has a 30/50 PSI switch, so adjust the tank
pre-charge pressure to 28 PSI.
Congratulations! You have just completed the
tank connection for your jet pump.
Please go to Page 7 for electrical hookup.
STANDARD TANK CONNECTION
(Figure 5)
Step 1. Install one tee in the pump discharge port (see
Figure 5).
Step 2. Run a pipe from the pump discharge port to the
inlet port of your tank. The pipe size must be at
least as large as the discharge port.
Step 3. Remove the 1/8" NPT pipe plug from the pump Air
Volume Control (AVC) port (see Figure 5). Run tub-
ing from the pump’s AVC port (see Figure 5) to the
port on the AVC mounted on the tank. See instruc-
tions provided with tank and AVC for details. AVC
port location will vary, depending on your pump
model (see exploded view, Page 11).
Congratulations! You have just completed the
tank connection for your jet pump.

Sealing Pipe Joints
Use only Teflon tape or Teflon based joint com-
pounds for making all threaded connections to the
pump itself. Do not use pipe joint compounds on
plastic pumps: they can react with the plastic in
pump components. Make sure that all pipe joints in
the suction pipe are air tight as well as water tight.
If
the suction pipe can suck air, the pump will not be
able to pull water from the well.

Electrical 7
Disconnect power before working on pump, motor, pressure switch, or wiring.
Hazardous voltage. Can shock, burn, or kill.
Connect ground wire before connecting power supply
wires. Use the wire size (including the ground wire) spec-
ified in the wiring chart. If possible, connect the pump to
a separate branch circuit with no other appliances on it.
Explosion hazard. Do not ground to a gas
supply line.
Motor Switch Settings
Dual-voltage motors (motors that can operate at either
115 or 230 volts), are set at the factory to 230 volts. Do
not change motor voltage setting if line voltage is 230
volts, or if you have a single voltage motor.
NOTE: Never wire a 115 volt motor to a 230 volt line.
NOTE: Wire TEFC motors according to wiring diagram in
junction box on motor. Be sure motor is connected for
correct line voltage.
NOTE: Wire 3-Phase motors according to wiring diagram
on motor. Be sure motor is connected for correct line
voltage.
Remove Motor End Cover
If you have a dual-voltage motor, and will connect it to
115 volts, follow the procedure below.
You will need to remove the motor end cover to change
the voltage setting.
Your motor terminal board (located under the motor end
cover) should look like the one below.
Dial Type Voltage Selector
To change to 115 volts:
1. Make sure power is off.
2. Turn the dial counter-clockwise until 115 shows in the
dial window.
3. Attach the power lead wires to the power lead termi-
nals. Make sure the wires are secure.
4. Attach the ground wire to the green ground screw
5. Reinstall the Motor end cover
Go to Wiring Connections below.
WIRING CONNECTIONS
Fire hazard. Incorrect voltage can cause a
fire or seriously damage the motor and voids the warran-
ty. The supply voltage must be within ±10% of the motor
nameplate voltage.
Install, ground, wire, and maintain your pump in compli-
ance with the National Electrical Code (NEC) or the
Canadian Electrical Code (CEC), as applicable, and with
all local codes and ordinances that apply. Consult your
local building inspector for code information.

Electrical / Preparing to Start the Pump 8
Connection Procedure:
Step 1. Connect the ground wire first as shown in Figure
8. The ground wire must be a solid copper wire
at least as large as the power supply wires.
Step 2. There must be a solid metal connection between
the pressure switch and the motor for motor
grounding protection. If the pressure switch is not
connected to the motor, connect the green ground
screw in the switch to the green ground screw
under the motor end cover. Use a solid copper
wire at least as large as the power supply wires.
Step 3. Connect the ground wire to a grounded lead in a
service panel, to a metal underground water
pipe, to a metal well casing at least ten feet (3M)
long, or to a ground electrode provided by the
power company or the hydro authority.
Step 4. Connect the power supply wires to the pressure
switch as shown in Figure 8.
PRIMING
Never run pump against closed discharge. To
do so can boil water inside pump, causing hazardous
pressure in unit, risk of explosion and possibly scalding
persons handling pump.
Never run pump dry. Running pump without
water may cause pump to overheat, damaging seal and
possibly causing burns to persons handling pump. Fill
pump with water before starting.
Step 1. Remove the priming plug from the pump and fill
the pump, fill all piping between the pump and
the well, and make sure that all piping in the
well is full. If you have also installed a priming
tee in the suction piping, remove the plug from
the tee and fill the suction piping.
Step 2. Replace all fill plugs.
Step 3. Power on! Start the pump. If you don’t have
water after 2 or 3 minutes, stop the pump and
remove the fill plugs. Refill the pump and piping.
You may have to repeat this several times in
order to get all the trapped air out of the piping.
A pump lifting water 25’ may take as long as 15
minutes to prime.
Step 4. After the pump has built up pressure in the sys-
tem and shut off, check the pressure switch oper-
ation by opening a faucet or two and running
enough water out to bleed off pressure until the
pump starts. The pump should start when pres-
sure drops to 30 PSI and stop when pressure
reaches 50 PSI. Run the pump through one or
two complete cycles to verify correct operation.
This will also help clean the system of dirt and
scale dislodged during installation.
Congratulations on a successful installation.
If you were unsuccessful, please refer to the
Troubleshooting section (Page 9) or call our customer
service technical staff.
