AT TACH ORIGINAL RECEIPT HERE FOR WARRANTY CONSIDERATION.
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.
Product Warranty Period
Water Systems Products – whichever occurs first:
jet pumps, small centrifugal 1 year from date of
pumps, submersible pumps original installation, or
and related accessories 2 years from date
of manufacture
Hydro-Flow Filters 1 year from date of purchase
Signature 2000 5 years from date of
Fibrewound Tanks original installation
Con-Aire
®
tanks 5 years from date of
original installation
Epoxy-Line Tanks 3 years from date of
original installation
Sump/Sewage/ 1 year from date of
Effluent Products original installation, or
2 years from date of manufacture
Our warranty will not apply to any product that has been subject to negligence, misapplication, improper installation 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 recommended 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 service 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 DAMAGES WHATSOEVER.
THE FOREGOING WARRANTIES ARE EXCLUSIVE AND IN
LIEU OF ALL OTHER EXPRESS WARRANTIES. 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.
Supersedes all previous publications.

Safety / Installation 3
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 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.
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 properly all unused tools and equipment.
Keep visitors at a safe distance from the work areas.
Pump body may explode if used as a
booster pump unless relief valve capable of passing full
pump flow at 75 psi is installed.
REPLACING AN OLD PUMP
Hazardous voltage. Disconnect power to
pump before working on pump or motor.
1. Drain and remove the old pump. Check the old pipe
for scale, lime, rust, etc., and replace it if necessary.
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.
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.
WARNING
Hazardous pressure!
Install pressure relief
valve in discharge pipe.
Release all pressure on
system before working on
any component.
WARNING
Hazardous voltage.
Can shock, burn, or
cause death.
Ground pump before
connecting to power
supply. Disconnect power
before working on pump,
motor or tank.
Wire motor for correct
voltage. See “Electrical” section of this manual
and motor nameplate.
Ground motor before
connecting to power
supply.
Meet National Electri-
cal Code, Canadian
Electrical Code, and local
codes for all wiring.
Follow wiring instruc-
tions in this manual
when connecting motor to
power lines.
Installation 4
WELL POINT (DRIVEN POINT)
INSTALLATION (Figure 1)
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 fittings” are also smoother than standard plumbing fittings, making ground penetration easier.
2. Mount the pump as close to the well as possible
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 connecting
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)
1. Mount the pump as close to the well as possible.
2. Assemble the foot valve, strainer, and well pipe (see
Figure 2). Make sure that the foot valve works freely.
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.
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.

your new shallow well jet pump. Please go to Page 6
