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 suction port 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 discharge port as shown 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.
NOTICE: Do not run the pump dry. This will damage
mechanical seal and void warranty.
Burn hazard. 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.

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.
California Proposition 65 Warning
This product and related accessories contain
chemicals known to the State of California to cause cancer,
birth defects or other reproductive harm.
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 3. 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 (Key No. 4, Page 6) may become damaged
and must be replaced. The procedure as outlined below will
enable you to replace the seal.
NOTICE: These mechanical seals are supplied with either
a rubber seat ring or a sealing O-Ring. They are com-
pletely 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 (Key No. 5, Page 6), carefully
remove rotating part of seal by prying up on sealing wash-
er, using two screwdrivers (see Figure 4A). Use care not
to scratch motor shaft.
2. Remove seal plate (Key No. 3) from motor and place on
flat surface, face down. Use a screwdriver to push ceramic
seat out from seal cavity (see Figure 4B).
INSTALLATION OF FLOATING SEAT
(Figure 4C)
1. Clean polished surface of floating (ceramic) seat with
clean cloth.
2. Turn seal plate over so seal cavity is up; clean cavity thor-
oughly.
3. Lubricate outside rubber surface or O-Ring 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 4D)
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 (see Figure 4D) 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
shoulder. This will automatically locate seal in place and
move the sealing washer face up against the facing seat.
Reinstall impeller screw (if used).

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.
BERKELEY SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL, INCIDENTAL, OR CONTINGENT DAMAGES WHATSOEVER.

BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE FOREGOING LIMITED
WARRANTIES SHALL NOT EXTEND BEYOND THE DURATION 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.
