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:
warns about hazards that will cause serious
personal injury, death or major property damage if ignored.
warns about hazards that can cause serious
personal injury, death or major property damage if ignored.
warns about hazards that will or can cause
minor personal injury or property damage if ignored.
The label 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
Capacitor voltage may be hazardous. To dis-
charge motor capacitor, hold insulated handle screwdriver BY THE
HANDLE and short capacitor terminals together. Do not touch
metal screwdriver blade or capacitor terminals. If in doubt, consult
a qualified electrician.
GENERAL SAFETY
Do not allow pump or any system component to freeze. To do so
will void warranty.
Pump water only with this pump.
Periodically inspect pump and system components.
Wear safety glasses at all times when working on pumps.
Keep work area clean, uncluttered and properly lighted; store prop-
erly all unused tools and equipment.
Keep visitors at a safe distance from the work areas.
To avoid over pressure hazard and possible injury, install pressure
relief valve capable of passing full pump flow at 75 PSI. Pressurized
suction may cause pump body to explode.
Do not touch an operating motor. Modern motors
are designed to operate at high temperatures. To avoid burns when
servicing pump, allow it to cool for 20 minutes after shut-down
before handling.
IMPORTANT / TANK SYSTEMS
Be sure all air pressure has been released from
tank before removing nuts from flange. Failure to do this may
result in serious or fatal injury!
NOTICE: If necessary to disassemble any part of tank, proceed as
follows:
1. Disconnect power to pump.
2. Drain ALL water in system by opening faucet closest to tank.
3. Relieve ALL air pressure in tank by depressing valve core. When
all air pressure is relieved, remove core from inside of air valve.
In areas where temperature is high for long periods of time, tank
pre-charge pressure may increase and reduce tank drawdown. If
this occurs, reduce pre-charge pressure to 2 PSI below “ON” set-
ting of pressure switch.
It is necessary to flush all air out of piping system and water reser-
voir portion of pre-charged tank. Open faucets farthest from tank
and allow pump to operate. Observe sputtering water flow from
faucets. Allow pump to run until steady stream of water discharges
from faucets. Open and close faucets repeatedly until all air has
been removed.
If air continues to remain in system, check for leaks in pump suc-
tion piping.

BEFORE YOU INSTALL YOUR PUMP
PRE-INSTALLATION
1. A pump cannot pump air. Make sure that suction pipe has
no air leaks.
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 protec-
tion requirements (usually pipe must be 12" 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.(Fig. 1).
NOTICE: A leak in suction may not drip (it allows air to be drawn
in). Jet pumps will not pump air and will not prime until all joints
are sealed properly.
8. Match pump to well. Shallow well is 25' or less to water with
pump running.(Fig. 2)
NOTICE: Flow in to well must at least equal flow out through
pump!
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 entire pump
flow at 75PSI is installed.
11. Be sure to prime pump before starting. Water acts as lubricant.
Starting without water will cause internal damage and void war-
ranty.
PUMP/PIPING INSTALLATION
PUMP INSTALLATION
NOTICE: Use Teflon tape supplied with pump for making all
threaded connections to pump itself. Do not use pipe joint com-
pounds on pump (it may react with plastic in pump components
and cause cracking.)
1. Bolt pump to solid, level foundation.
2. Support all piping connected to pump to prevent pump breakage.
3. Wrap 1-1/2 to 2 layers of Teflon tape clockwise (as you face end
of pipe) on all male threads being attached to pump.
4. Tighten joints hand tight plus 1-1/2 turns. Do not overtighten.
Overtightening may damage pump and will void warranty.
NOTICE: Install pump as close to well head as possible. Long pip-
ing runs and many fittings create friction and reduce flow.
NOTICE: For long horizontal pipe runs, install priming tee between
check valve and well head. (Fig. 6). For driven point installations
where horizontal piping is more than 25 feet long, install check
valve (Fig. 7). Be sure check valve flow arrow points toward pump.
See “Well Pipe Installation” for more information.
3
Use teflon tape or
pipe joint compound
approved for use on PVC.
No air leaks.

Figure 1 – Suction pipe must not leak Figure 2– Match pump to well
Use check valve with drive point.

PRESSURE TANK CONNECTION
PRESSURE TANK (FIG. 3)
Hazardous pressure. To avoid tank blowup,
install relief valve capable of passing full system flow at 75
PSI.
PRESSURE TANK provides reservoir of water under pressure and
maintains cushion of air pressure to prevent pipe hammer and pos-
sible 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 (FIG. 4 )
When standard tank is used, air volume control (AVC) adds air to
the tank when needed. To connect AVC to pump, remove 1/8" pipe
plug from pump body near suction port (Fig. 4). Thread 1/8" com-
pression fitting into tapped hole. 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.
PRE-CHARGED TANK CONNECTION (FIG. 5)
When pre-charged tank is used, no AVC is necessary. Pre-
charged tank contains factory provided air charge.
NOTICE: Your pump pressure switch is set for a 30-50 PSI range
and requires tank pre-charge of 28 PSI for proper operation. See
tank owner’s manual for instructions on checking tank air charge.
An annual check on tank charge is recommended to prevent
excessive running of pump.

WELL PIPE INSTALLATION
NOTICE: Use installation method which matches your well type.
CASED WELL/DUG WELL INSTALLATION (FIG. 6)
1. Inspect foot valve to be sure it works freely. Inspect strainer to be
sure it is clean.
2. Connect foot valve and strainer to first length of suction pipe and
lower pipe into well. Add sections of pipe as needed, using teflon
tape on male threads. Be sure all suction pipe is leakproof or
pump will lose prime and fail to pump. Install foot valve 10 - 20
ft. below lowest level to which water will drop while pump is oper-
ating (pumping water level). Contact your local well driller for
more information.
3. To prevent sand and sediment from entering pumping system,
foot valve/strainer should be at least 5 ft. above bottom of well.
4. When proper depth is reached, install sanitary well seal over pipe
and in well casing. Tighten the bolts to seal casing.
5. When using foot valve, use priming tee and plug.
DRIVEN POINT INSTALLATION (FIG.7)
1. Connect suction pipe to drive point. Keep horizontal pipe run
short. Use Teflon tape on male pipe threads.
2. Install check valve near the well point. Check valve flow arrow
must point toward pump.
LAKE INSTALLATION (FIG. 8)
Same as cased well except as follows:
1. Protect end of suction pipe, foot valve and strainer with screen-
ing.
2. Install suction pipe far enough below lake level so end of pipe will
be submerged at all times. End of suction pipe must be off lake
bottom to keep sand and sediment from entering system, caus-
ing pump failure.

OPERATION
PRIMING THE PUMP (FIG. 10)
Do not run pump with discharge shut off. Pump
can boil water, causing steam burns when opening pump, blowing
up pump body, or causing internal (seal) damage to pump.
NEVER run pump dry. Running pump without
water may overheat pump, damaging internal parts and caus-
ing burns if handled. To prevent damage, fill pump with water
before starting.
1. Remove priming plug.
a. Fill pump and suction pipe with water.
b. Replace priming plug, using Teflon tape on plug thread;
tighten plug.
NOTICE: If priming tee and plug have been provided for
long horizontal run, be sure to fill suction pipe through this
tee and replace plug (remember to teflon tape the plug).
2. Start pump and run two minutes or less. Unit should pump water.
If not, stop pump and repeat steps under No. 1. On first use of
pump, it may be necessary to reprime unit 2 - 3 times before all
air is out of suction pipe.
3. If, after priming pump several times, no water is pumped, make
sure that:
a. Suction pipe end is in water.
b. Suction pipe has no air leaks.
c. Pump is not trying to lift water more than 25 ft.
d. Pump is not air locked: Pump suction port should be high-
est point in suction pipe; no sags in suction pipe (run it
straight and angled slightly upward from well head to
pump).
e. Piping is clean and in good condition.
NOTICE: As long as foot valve and check valve function
correctly and suction pipe does not develop leaks, pump
should not need repriming in normal service.
SERVICE
Risk of electrical shock. Be sure unit is ground-
ed and power disconnected before attempting any work on
pump or motor.
Your pump is designed for ease in servicing. Should repair or
replacement of the motor or seal be needed, the pump and piping
do not need to be disconnected or disturbed.
(If it is necessary to replace the motor, it is a good idea to replace
the seal plate “O” Ring and the shaft seal, Key Nos. 4 and 6, Page
10. We suggest that you order these two items to have on hand for
future use.)
MAINTENANCE
LUBRICATION
It is not necessary to lubricate the pump or its motor. The motor
bearings are lubricated for life. The mechanical shaft seal in the
pump is water lubricated and self-adjusting.
CLEANING SHALLOW WELL JET
1. Disconnect power.
2. Remove pressure switch tube from pump body and allow pump
to drain.
3. Remove four hexnuts (Key No. 23, Page 11) which hold the
pump body to the motor.
4. Remove motor, seal plate, impeller and diffuser (Key Nos. 1, 3,
7, 9, Page 11) as a unit.
5. Carefully insert an icepick or other small diameter pointed tool
into venturi (Key No. 17, Page 11) and into nozzle (behind ven-
turi, Key No. 16, Page 11), dislodging foreign material.
NOTICE: Be careful not to enlarge hole in nozzle or venturi.
6. Foreign matter will drop to the bottom of the pump body (directly
below nozzle) and must be removed.
7. Install new “O” Ring gasket on seal plate (Key No. 4, Page 11).
8. Pick up small amount of liquid soap on finger; spread evenly over
“O” Ring gasket for lubrication during reassembly. Be careful not
to nick or tear “O” Ring.
9. Replace motor onto pump body. Be sure rubber pad (Key No. 8,
Page 11) stays in place on diffuser. Tighten four hexnuts snugly
(35-34 inch-lbs. torque). Do not overtighten.
10. Replace pressure switch tubing and motor wiring.
11. Prime pump according to instructions above.
12. Check for leaks.
REPLACING VENTURI / NOZZLE
1. Follow steps 1 through 4 under Cleaning Shallow Well Jet
(above) for pump disassembly.
2. Remove venturi (Key No. 17, Page 11) by unscrewing it (turn
counterclockwise).
3. Remove nozzle (if necessary) by unscrewing it with a 5/8” hex
socket wrench.
4. Replace nozzle and venturi by turning in clockwise until snug. Do
not overtighten.
5. Follow steps 7 through 12 under Cleaning Shallow Well Jet
(above) for pump reassembly.
CLEANING / REPLACING IMPELLER
1. Follow steps 1 through 4 under Cleaning Shallow Well Jet
(Above) for pump disassembly.
2. Remove two screws (Key No. 10) fastening diffuser (Key No. 9,
Page 11) to seal plate; remove diffuser.
3. Exposed impeller (Key No. 7, Page 11) can now be cleaned.
4. If impeller must be replaced, loosen two machine screws and
remove motor canopy (Key No. 1, Page 11).
5. If motor has capacitor, partially unscrew capacitor clamp and
move capacitor to one side.
To avoid electrical shock do not touch capaci-
tor terminals with body or metal objects.
6. Hold motor shaft with 7/16” open end wrench on the motor shaft
flat (at motor end of shaft).
7. Unscrew impeller by turning counterclockwise (when facing
impeller).
8. To reinstall impeller, reverse steps 2 through 7 above.
9. Follow steps 7 through 12 under Cleaning Shallow Well Jet
(above) for pump assembly.

REPLACING SHAFT SEAL
REPLACING OLD SEAL
1. Follow steps 1 through 7 under Cleaning/Replacing Impeller
(above) for pump disassembly.
2. Remove rotating half of seal by placing two screwdrivers under
seal plate and carefully prying up (Figure 11). Seal plate will slide
off shaft, bringing seal with it.
FIGURE 11
NOTICE: Be sure you do not scratch or mar shaft; if shaft is
marred, it must be dressed smooth with fine emery or crocus
cloth before installing new seal.
3. Place seal plate face down on flat surface and tap out stationary
half of seal. NOTICE: Be sure you tap on ceramic seat, not on
copper insert. Do not disturb copper insert.
INSTALLING NEW SEAL
1. Clean seal cavity in copper insert. Do not disturb copper
insert. (If insert is moved or dislodged, see instructions for
Installing Copper Insert.)
2. Wet outer edge of “O” Ring on ceramic seat with liquid soap. Be
sparing!
3. With thumb pressure, press ceramic seal half firmly and squarely
into seal cavity in copper insert (Figure 12). Polished face of
ceramic seat faces inside of pump. If seal will not seat correctly,
remove it and reclean cavity, placing seal face up on bench.
Seal should now seat correctly.
FIGURE 12
4. If seal does not seat correctly after recleaning cavity, place a
cardboard washer over polished seal face and carefully press
into place using a piece of standard 3/4” pipe as a press.
NOTICE: Be sure you do not scratch seal face.
5. Dispose of cardboard washer and recheck seal face to be sure it
is free of dirt, foreign particles, scratches and grease.
6. Inspect shaft to be sure it is free of nicks and scratches.
7. Reinstall seal plate on motor flange, making sure that it is right
side up (index pins down; top of plate is marked).
8. Apply liquid detergent sparingly to inside diameter of rotating
seal member.
9. Slide rotating seal member (carbon face first) onto shaft until rub-
ber drive ring hits shaft shoulder.
NOTICE: BE SURE not to nick or scratch carbon face of seal
when passing it over threaded shaft end or shaft shoulder.
10. Hold motor shaft with 7/16” open end wrench on shaft flat and
screw impeller onto shaft. This will automatically locate seal in
correct position.
11. Reinstall diffuser on seal plate with two screws.
12. Follow steps 7 through 12 under Cleaning Shallow Well Jet
(above) for pump reassembly.
INSTALLING STAINLESS STEEL INSERT
NOTE: If the stainless steel insert moves or shifts during seal
removal, it should be removed and reinstalled.
1. Remove stainless steel insert as shown in Figure 13. Do not
deform.
FIGURE 13
2. Replace stainless steel insert:
A. Clean off all surplus Permatex* from around insert cavity. Be
careful not to scratch or mark the machined bore. It is important
that this area be clean so no old Permatex lodges behind the
new insert and causes improper seating.
B. Place small amount of No. 2 non-hardening Permatex on surface
of insert as shown. Smooth out with finger. See Figure 14.

HELPFUL HINTS
HOW TO HANDLE A GASEOUS WELL
In some areas well water contains gases which must be allowed to
escape before the water is used.
To deliver gas-free water suspend a pipe, closed at the bottom and
open at the top, so that it surrounds the suction pipe inlet. (See
Figure 17). Since the gases rise in the well casing, the water
sucked down through the pipe and into the suction pipe is free of
gas. This type of well must be vented to the outside of any enclo-
sure.
AIR CONTROL IN FLOWING WELLS
Flowing wells, or wells with little or no drawdown, could create a
special problem in air control in the operation of your water sys-
tems.
In such cases, install a Con-Aire Tank. It does not require any air
control.

LIMITED WARRANTY
Sta-Rite warrants to the original consumer of the products listed below, that they will be free from defects in
material and workmanship for the Warranty Period from the date of original installation or manufacture as noted.

small centrifugal pumps, submersible pumps 1 year from date of original installation, or
and related accessories 2 years from date of manufacture
Con-Aire®tanks 5 years from date of original installation
Epoxy-Line Tanks 3 years from date of original installation
Environmental Products 1 year from date of original installation, or

Our warranty will not apply to any product that has been subject to negligence, misapplication, improper instal-
lation or maintenance. In the event a three phase submersible motor is operated with single phase power
through a phase converter, or if three-leg ambient compensated, extra-quick trip overload relays of recom-
mended size are not used, our warranty is void.
Buyer’s only remedy and Sta-Rite’s only duty is to repair or replace defective products (at Sta-Rite’s choice).
Buyer agrees to pay all labor and shipping charges associated with this warranty and to request warranty ser-
vice through the installing dealer as soon as a problem is discovered. If warranty service is requested more
than 30 days after the Warranty Period has ended, it will not be honored.
STA-RITE SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL, INCIDENTAL, OR CONTINGENT DAM-
AGES WHATSOEVER.
THE FOREGOING WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL OTHER EXPRESS WAR-
RANTIES. IMPLIED WARRANTIES, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, SHALL NOT EXTEND BEYOND THE
WARRANTY PERIOD PROVIDED HEREIN.
Certain states do not permit the exclusion or limitation of incidental or consequential damages or the placing of
limitations on the duration of an implied warranty, therefore, the limitations or exclusions herein may not apply.
This warranty sets forth specific legal rights and obligations, however, additional rights may exist, which may
vary from state to state.
