READ AND FOLLOW

SAFETY INSTRUCTIONS!

This is the safety alert symbol. When you see this

symbol on your pump or in this manual, look for
one of the following signal words and be alert to the
potential for personal injury!

DANGER warns about hazards that will

cause serious personal injury, death or major property
damage if ignored.

WARNING warns about hazards that can

cause serious personal injury, death or major property
damage if ignored.

CAUTION warns about hazards that will or

can cause minor personal injury or property damage if

ignored.
The word NOTICE indicates special instructions which

are important but not related to hazards.

Carefully read and follow all safety instructions in this
manual and on pump.

Keep safety labels in good condition.
Replace missing or damaged safety labels.

ELECTRICAL SAFETY

Wire motor for correct

voltage. See “Electrical”
section of this manual and
motor nameplate.

Ground motor before

connecting to power
supply.

Installation 5

PRE-INSTALLATION

1. A pump cannot pump air.

2. Long runs and many fittings increase friction and
reduce flow. Locate pump as close to well as possi­ble. Keep pipe straight and angled up to pump. Use
as few elbows and fittings as possible. Support weight
of pipe.

3. Be sure well is clear of sand, dirt and scale which
will plug pump and void warranty.

4. Protect pump and piping from freezing. Freezing will
split pipe, damage pump and void warranty. Check
locally for frost protection requirements (usually pipe
must be 12" (30.5 cm) below frost line and pump
must be insulated).

5. Be sure pipes and foot valve are clean and in good
shape. Leaking foot valve due to dirt or scale may
allow pump to lose prime and cause pump failure.

6. No air pockets in suction pipe.

7. No air leaks in suction pipe. Use Teflon tape or
Plasto-Joint Stik to seal pipe joints. Do not use pipe
joint compound. (Figure 1).

NOTICE: A leak in suction may not drip (allows air to
be drawn in). Jet pumps will not pump air or prime
until all joints are sealed properly.

8. Match pump to well. Deep well is 25' (7.6M) or more
to water with pump running. (Figure 2)

NOTICE: Flow in to well must at least equal flow out
through pump! See Performance Chart.

9. Unions installed near pump and well will aid in ser­vicing. Leave room to use wrenches.

10. Pump body may explode if used as

booster pump unless relief valve capable of passing
full pump flow at 75PSI (517kPa) is installed.

11. Be sure to prime pump before starting. Water acts as
lubricant. Starting without water will cause internal
damage and void warranty.

DEEP WELL / DOUBLE PIPE

PIPING IN THE DEEP WELL (Figures 3 & 4)

NOTICE: Deep well installations are either single pipe

(2” wells) or double pipe (4” and larger wells). In a dou­ble pipe installation, the larger pipe is the suction pipe
and the smaller pipe is the drive pipe (very deep wells
may use suction and drive pipes of the same diameter).
Suction pipe always aligns with center of pump.

Plastic pipe is ideal for double pipe installations. Due to
its light weight, it is easy to handle and does not usually
require a block and tackle for installation and removal.

PLASTIC PIPE INSTALLATION –
DOUBLE PIPE (Figures 3 & 4)

NOTICE: Use Teflon tape on all male threads on plastic

pipe and fittings to prevent air leaks in suction piping.

1. Inspect jet to make sure that nozzle and venturi
openings are clean and clear.

2. Inspect pipe for any foreign matter or obstructions.
IMPORTANT: Make sure that no foreign matter enters

pipe openings while installing pump.

3. Make sure foot valve operates freely: attach to jet
with a close nipple. Use Teflon tape on male threads.

4. Install nozzle and venturi in deep well jet. Consult
Table II for proper nozzle and venturi.

5. Using Teflon tape on male threads, install special
plastic pipe adapter (supplied with jet package) by

screwing adapter into 1-1/4” tapped hole in ejector
body.

6. Thread a 1” plastic pipe adapter into the 1” tapped
hole in jet body.

7. Install sufficient plastic pipe in well casing to place
jet at the proper depth. (Your well driller should sup­ply this information.)

IMPORTANT: As a guide, the jet should be set at least
10 to 20 ft. (3-6M) below lowest water level with
pump running, but always at least 5 ft. (1.5M) from
bottom of well.

8. Tighten hose clamps on plastic pipe. Use 2 clamps
per joint to prevent air leaks into suction pipe. Clamp
screws should be on opposite sides of pipe. Fill pipes
with water to make sure foot valve and connections
do not leak.

9. Install sanitary well seal on top of well casing; use
steel nipple through well seal.

IMPORTANT: Align locating lugs on adapter flange
and pump base so pump discharge will be aligned
with piping.

10.Install nipple in drive pipe side of adapter flange.
Slide threadless coupling down over drive pipe from
well. Thread adapter flange onto suction pipe from
well and align nipple and drive pipe.

11. Slide threadless coupling up and secure nipple to
drive pipe.

12.Apply gasket to adapter flange. Be sure holes line up.

13.Align locating lugs on pump base with locating lugs
on adapter flange; attach pump to flange with cap
screws provided.

14.See “Discharge Pipe Sizes” for information regarding
correct discharge pipe size.

DEEP WELL / SINGLE PIPE

2" SINGLE PIPE JET DEEP WELL
INSTALLATION (Figures 5 and 6)

Single pipe installations require :

A. Galvanized steel pipe
B. Leather packer-type jet with built-in foot valve
C. Turned couplings (supplied with jet package)

D. Well casing adapter and adapter flange (supplied

with jet package)
E. Offset nipple (supplied with jet package)
F. Pipe holders (see Figure 6B)

1. Place jet in pail of water for two or more hours to
soak cup seals. See Table III for proper venturi and
nozzle.

2. After cup seals are thoroughly soaked, connect jet to
first length of pipe. Use pipe joint compound sparing­ly on male threads.

NOTICE: Due to normal irregularities in the leather of
the cup seals and the inner walls of the drop pipe, 2"
packer jets do not form a perfect seal. In a dormant
system, water will leak back into well over time and
pump will normally start and cycle to maintain sys­tem pressure level.

3. Lower pipe into casing. Use specially turned cou­plings (included with 2” single pipe jet package) to
increase water flow. Use pipe joint compound spar­ingly on male couplings threads.

NOTICE: Fill pipe with water as each length is added
to be sure foot valve and connections do not leak.

4. Add lengths of pipe until jet reaches proper depth.
(Contact your local well driller.)

IMPORTANT: As a guide, the jet should be set at least
10 to 20 ft. (3-6M) below lowest water level with
pump running, but always at least 5 ft. (1.5M) from
bottom of well.

5. With jet at the proper depth for your installation,
mark the drop pipe 6” above the top of the well cas­ing, then raise the drop pipe about 18 inches and
clamp it there to allow room to install the casing
adapter, offset nipple, and adapter flange.

6. Cut off the drop pipe at the mark you made in Step 5.
Thread the top of the pipe 1” NPT to take the adapter
flange.

7. Slide the casing adapter over the top of the drop pipe
with bolts in place and leave it loose on the pipe.

8. Thread the drop pipe into the adapter flange; thread
the offset nipple into the adapter flange until it is tight
and aligns with its port inthe casing adapter.

9. Remove pipe holder and lower pipe assembly until
casing adapter seats on well head and offset nipple
seats in casing adapter port. Before tightening casing
adapter bolts, move assembly up and down slightly.
Water pressure in the casing will seal the cup seals.

10.Tighten casing adapter bolts to fasten the casing
adapter to the well casing.

11. Install gasket on adapter flange and bolt pump to
adapter flange.

IMPORTANT: Align locating lugs on adapter flange
and pump base so that pump discharge will be
aligned with piping.

DISCHARGE PIPE SIZES

1. If increasing discharge pipe size, install reducer in
pump discharge port. Do not increase pipe size by
stages.

2. When pump is set away from the points of water use,
discharge pipe size should be increased to reduce
pressure losses caused by friction.

• Up to 100 ft (30M) run: Same size as pump dis­charge port.

• 100 ft. to 300 ft (30-91M) run: Increase one pipe
size.

• 300 ft. to 600 ft (91M-183M)run: Increase two
pipe sizes.

PRESSURE TANK INSTALLATION –
DEEP WELL

A pressure tank provides a reservoir of water under pres­sure and maintains a cushion of air pressure to prevent
pipe hammering and possible damage to plumbing com­ponents. When water is drawn off through house fixtures,
pressure in tank is lowered and pressure switch starts
pump.

STANDARD TANK CONNECTION (Figure 7)

With a standard tank - an air volume control (AVC) adds
air to the tank when needed.To connect AVC to pump,
thread a 1/8” compression fitting into tapped hole on
front of pump. Cut tubing to length to reach AVC; assem­ble to fitting on pump and to AVC on tank. See installa­tion instructions provided with tank and AVC for details.

PRECHARGED TANK CONNECTION
(Figure 8)

No AVC is necessary with a precharged tank. A
precharged tank contains a factory provided air charge.

IMPORTANT: Pump pressure switch is set for a 40-60 PSI
(275-414kPa) range and requires a tank pre-charge of 38
PSI (262 kPa) for proper operation. See tank owner’s
manual for air charge. An annual check on tank air
charge is recommended.

ELECTRICAL

Ground motor before
connecting to electrical

power supply.

Failure to ground motor
can cause severe or fatal

electrical shock hazard.

Do not ground to a gas
supply line.

To avoid dangerous or

fatal electrical shock,
turn OFF power to motor
before working on electrical
connections.

Supply voltage must be

within ±10% of name-

plate 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.

Plug Type Voltage Selector

Voltage is factory set to 230 volts. To change to 115 volts:

1. Make sure power is off.

2. Pull the voltage change plug off of the tabs.

3. Move the voltage change plug to the 115 volt posi­tion. The plug will now cover 2 metal tabs and the
arrow on the plug will line up with the 115V arrow on
the label (see Figure 10).

4. Attach the incoming power leads to the two outer
screws on the pressure switch as shown in Figure 9.

5. Attach the ground wire to one of the grounding
connections, shown in Figure 9.

6. If there are other wires, they should be capped.

7. Reinstall the Motor end cover.

Dial Type Voltage Selector

Voltage is factory set to 230 volts. To change to 115 volts:

1. Make sure power is off.

2. Turn the dial counter-clockwise until 115 shows in the
dial window as shown in Figure 12.

3. Attach the incoming power leads to the two outer
screws on the pressure switch as shown in Figure 11.

4. Attach the ground wire to the grounding connections
as shown in Figure 11.

5. If there are other wires, they should be capped.

6. Reinstall the Motor end cover.

NOTE: 1/2 HP motors are wired for 115 volts only, and have no motor wiring to change.
Your motor terminal board (located under the motor end cover) should look like one of those below.
If the motor can operate at either 115 or 230 volts, it is set at the factory to 230 volts. Do not change motor wiring if
line voltage is 230 volts, or if you have a single voltage motor.

Never wire a 115 volt motor to a 230 volt line.

Wiring (Figure 9)

1. Install, ground, wire and maintain pump in accor­dance with your local electrical code and all other
codes/ordinances that apply. Consult your local
building inspector for local code information.

2. Ground pump permanently using wire of size and
type specified by approved local or national codes.

Risk of explosion. Do not ground to gas

supply line.

3. Connect ground wire first. Connect to ground first,
then to green grounding terminal provided on pres-

sure switch identified as GRD. Ground connection
MUST be made to this terminal. Do not connect
motor to electrical power supply until unit is perma­nently grounded; otherwise serious or fatal electrical
shock hazard may be caused.

4. For best ground connection, connect to grounded
lead in service panel or to metal underground water
pipe or well casing at least 10 ft. (3 M) long. If plastic
pipe or insulated fittings are used, run ground wire
directly to metal well casing or use ground electrode
furnished by the power company.

Operation 11

PRIMING THE PUMP (Figure 13)

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.

NEVER run pump against closed discharge.
To do so can boil water inside pump, causing hazardous
pressure in unit and possibly scalding persons handling
pump.

NOTICE: Open water system faucets before priming

pump for the first time.

1. Remove pressure gauge.

A. Close regulator valve (turn clockwise).
B. Fill pump and suction pipe with water.
C. Replace pressure gauge, using teflon tape on

thread; tighten gauge.

IMPORTANT: If a priming tee and plug have been pro­vided for a long horizontal run, fill suction pipe through
tee and replace plug. (Remember: teflon tape plug.)

2. Start Pump:

Pressure should build rapidly to 50 PSI (345 kPa) or
more as jet and pump prime.

IF NO PRESSURE OR NO WATER, REPEAT
STEP No.1 two or three times to remove entrapped
air from suction pipes.

3. If, after priming pump several times and no water is
pumped, make sure that:

A. Suction pipe is in the water and has no leaks.

NOTE: Air can leak in where water won’t leak out.
Make sure all joints are tight.

B. Control valve, check valve, or foot valve is

installed and operating correctly.

C. Pump is not trying to lift water more than 25 feet

(7.6M) (shallow well) or more than rated lift for
deep well jet used (including compensation for
horizontal piping). See “Performance and Jet
Chart” for your installation.

D. Pump is not airlocked, suction port should be

highest point in suction pipe; no sags in suction
pipe (run it straight and angled slightly upward
from well head to pump).

NOTE: For deep well installation, go to step 4.
Shallow well installations go to step 6.

4. Once unit has primed and pressure is stabilized,
slowly open regulator valve (turn counterclockwise)
until pressure falters (pressure gauge needle flutters).
Close control valve (turn clockwise) slightly until
pressure stabilizes. This setting provides maximum
flow.

5. Pump may draw well down far enough to lose its
prime. If so, close regulator valve until pressure is sta­ble throughout pumping cycle. Close faucets and
allow pump to pressurize tank and shut off.

6. Check system by alternately opening and closing
faucets in the system. With faucets open, pressure
will drop until pump starts; with faucets closed, pres­sure will build up until pump shuts off.

7. There are conditions of deep well operation when the
regulator valve may be completely open without any
faltering of pressure. In this case, operate pump with
regulator valve open.
