PIPING - GENERAL
Support both suction and discharge piping independently at
a point near the pump to avoid putting a strain on the pump
housing. Start all piping AT THE PUMP.
Increase pipe diameter at both the suction and discharge
by one (1) standard pipe size (minimum) to obtain desired
performance and flow rate. Refer to Table I when sizing pipe
for your pumping system.
NOTICE: Do not use pipe with smaller diameter on the suction
side of pump.

SUCTION PIPE
Increase pipe size from pump tapping as shown in Table I.
Figure 1 (Page 2) depicts a recommended run of pipe and
fittings for the suction side of a centrifugal pump. Please refer
to this illustration when choosing pipe and fittings for your
suction connection.
IMPORTANT: All connections must be air tight!
Figure 2 (Page 2) depicts conditions that are NOT DESIRABLE
on the suction side of a centrifugal pump and may cause
problems in flow rate and priming. Please look this illustration
over carefully before choosing pipe and fittings for your suction
connection.
DISCHARGE PIPING
Increase pipe size from pump tapping as show in Table I.
Figure 1 (Page 2) depicts a recommended run of pipe and
fittings for the discharge. Install tee with priming plug as close
to pump as possible. Figure 2 (Page 2) notes conditions that
should be avoided. Please read over carefully before making
discharge connection.
PRIMING THE PUMP
A pump is primed when all air in the suction line and pump
volute has been evacuated and replaced with water.
To Prime:
1. Close valve in discharge line.
2. Remove priming plug from tee and fill pump and suction line
with water until water is flowing back out of tee.
3. Replace priming plug.
4. Start pump and slowly open valve until desired water flow is
achieved.
NOTICE: If water is not being pumped, turn off pump, close
valve, and repeat steps 1 thru 4.
If pump volute is rotated as shown in Figure 1 (Page 2), loosen
vent plug when priming to evacuate air trapped inside volute
and tighten when volute is completely filled with water.
Risk of explosion and scalding. Never run
pump against closed discharge. To do so can boil water inside
pump, causing hazardous pressure buildup and possible
explosion.
Risk of flooding. Do not run the pump dry. This
will damage mechanical seal and void warranty. It may cause
burns to person handling pump.
Motor normally operates at high temperature
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.

Connection diagram for dual voltage, single-phase
motors. Your dual-voltage motor’s terminal board (under the
motor end cover) will match one of the diagrams below. Follow
that diagram if necessary to convert motor to 115 Volt power.
Connect power supply wires to L1 and L2. For 3-phase
motors, or if motor does not match these pictures, follow the
connection diagram on the motor nameplate.
THE MOTOR IS SET FOR 230 VOLTS
WHEN SHIPPED.
To change the motor to use 115 volts:
1. Turn off power
2. Remove the back motor cover.
3. Use a screwdriver or 1/2” wrench and turn the voltage
selector dial counterclockwise until 115 shows in the dial
opening.
4. Reinstall the motor cover.
Hazardous voltage. Can shock, burn, or
cause death. Disconnect power to motor before working on
pump or motor. Ground motor before connecting to power
supply.
WIRING
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 nameplate
voltage. Incorrect voltage can cause fire or damage
motor and voids warranty. If in doubt consult a
licensed electrician.
Use wire size specified in Wiring Chart (Page 3). If
possible, connect pump to a separate branch circuit
with no other appliances on it.
Wire motor according to diagram on motor nameplate.
If nameplate diagram differs from diagrams above,
follow nameplate diagram.
1. Install, ground, wire and maintain your pump in compliance
with the National Electrical Code (NEC) in the U.S., 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.
2. Provide a correctly fused disconnect switch for protection
while working on motor. For switch requirements, consult
your local building inspector for information about codes.
3. Disconnect power before servicing motor or pump. If the
disconnect switch is out of sight of pump, lock it open and
tag it to prevent unexpected power application.
4. Ground the pump permanently using a wire of the same
size as that specified in wiring chart (Page 3). Make ground
connection to green grounding terminal under motor canopy
marked GRD. or .
5. Connect ground wire to a grounded lead in the service panel
or to a metal underground water pipe or well casing at least
10 feet long. Do not connect to plastic pipe or insulated
fittings.
6. Protect current carrying and grounding conductors from
cuts, grease, heat, oil, and chemicals.
7. Connect current carrying conductors to terminals L1 and L2
under motor canopy. When replacing motor, check wiring
diagram on motor nameplate against Figure ##. If the motor
wiring diagram does not match either diagram in Figure 3,
follow the diagram on the motor.
IMPORTANT: 115/230 Volt single phase models are shipped
from factory with motor wired for 230 volts. If power supply
is 115 volts, remove motor canopy and reconnect motor as
shown in Figure 3. Do not try to run motor as received on 115
volt current.
8. Motor has automatic internal thermal overload protection. If
motor has stopped for unknown reasons, thermal overload
may restart it unexpectedly, which could cause injury or
property damage. Disconnect power before servicing motor.
9. If this procedure or the wiring diagrams are confusing,
consult a licensed electrician.

PUMP SERVICE
This centrifugal pump requires little or no service other than
reasonable care and periodic cleaning. Occasionally, howev-
er, a shaft seal may become damaged and must be replaced.
The procedure as outlined below will enable you to replace
the seal.
NOTICE: Pumps use mechanical seals with a rubber
seat ring or a sealing O-Ring. THESE SEALS ARE
COMPLETELY INTERCHANGEABLE.
NOTICE: The highly polished and lapped faces of this seal
are easily damaged. Read instructions and handle the seal
with care.
Some models are equipped with an impeller screw, which has
a left hand thread. Before unscrewing the impeller, remove
the impeller screw.
REMOVAL OF OLD SEAL
1. After unscrewing impeller, carefully remove rotating part
of seal by prying up on sealing washer, using two screw-
drivers (see Figure 5A). Use care not to scratch motor
shaft.
2. Remove seal plate from motor and place on flat surface,
face down. Use a screwdriver to push ceramic seat out
from seal cavity (see Figure 5B).
INSTALLATION OF FLOATING SEAT (Figure 5C)
1. Clean polished surface of floating seat with clean cloth.
2. Turn seal plate over so seal cavity is up, clean cavity thor-
oughly.
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 5D)
1. Reinstall seal plate using extreme caution not to hit ceram-
ic 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 shoul-
der. This will automatically locate seal in place and move
the sealing washer face up against seat facing. Reinstall
impeller screw (if used).

Limited Warranty
STA-RITE warrants to the original consumer purchaser (“Purchaser” or “You”) of the products listed below, that they will be free
from defects in material and workmanship for the Warranty Period shown below.
Product Warranty Period
Water Systems Products — jet pumps, small centrifugal pumps,
submersible pumps and related accessories
whichever occurs first:
12 months from date of original installation,
or 18 months from date of manufacture
Pro-Source®Composite Tanks 5 years from date of original installation
Pro-Source®Steel Pressure Tanks 5 years from date of original installation
Pro-Source®Epoxy-Lined Tanks 3 years from date of original installation
Sump/Sewage/Effluent Products 12 months from date of original installation, or
18 months from date of manufacture
Our warranty will not apply to any product that, in our sole judgement, has been subject to negligence, misapplication,
improper installation, or improper maintenance. Without limiting the foregoing, operating a three phase motor with single phase
power through a phase converter will void the warranty. Note also that three phase motors must be protected by three-leg,
ambient compensated, extra-quick trip overload relays of the recommended size or the warranty is void.
Your only remedy, and STA-RITE’s only duty, is that STA-RITE repair or replace defective products (at STA-RITE’s choice). You
must pay all labor and shipping charges associated with this warranty and must request warranty service through the installing
dealer as soon as a problem is discovered. No request for service will be accepted if received after the Warranty Period has
expired. This warranty is not transferable.
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 AND IMPLIED WARRANTIES,
INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE FOREGOING WARRANTIES SHALL NOT EXTEND BEYOND THE DURATION EXPRESSLY PROVIDED HEREIN.
Some states do not allow the exclusion or limitation of incidental or consequential damages or limitations on the duration of an
implied warranty, so the above limitations or exclusions may not apply to You. This warranty gives You specific legal rights and
You may also have other rights which vary from state to state.
This Limited Warranty is effective June 1, 2011 and replaces all undated warranties and warranties dated before June 1, 2011.
