PIPING - GENERAL
Support both suction and discharge piping indepen-
dently 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 dis-
charge 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.
NOTE: Do not use pipe with smaller diameter on the
suction side of pump.

SUCTION PIPE
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 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 choos-
ing 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 suc-
tion 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.
NOTE: 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.
Never run pump against closed dis-
charge. To do so can boil water inside pump causing
hazardous pressure in unit, risk of explosion and possi-
bly scalding persons handling pump.
Do not run the pump dry. This will dam-
age mechanical seal and void warranty.
Motor normally operates at high temper-
ature 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.

4
Ground motor before con-
necting 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 seriously damage
motor and voids warranty. If in
doubt consult a licensed
electrician.
Use wire size specified in
Wiring Chart (below). 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 below, follow
nameplate diagram.
WIRING
1. Install, ground, wire and maintain this pump in accordance
with your local electrical code and all other codes and ordi-
nances that apply. Consult your local building inspector for
local code information.
2. Ground the pump permanently using a wire of size and
type specified by local or National Electrical Code.
Do not ground to gas supply line.
3. Connect ground wire first. Connect to ground first, then to
green grounding terminal provided under motor canopy
(see Figures 3A and 3B) identified as GRD. Make ground
connection to this terminal. Do not connect motor to elec-
trical power supply until unit is permanently grounded; oth-
erwise serious or fatal electrical shock hazard may be
caused.
4. For best ground connection, connect to a grounded lead in
the service panel or to a metal underground water pipe or
well casing at least 10 ft. long. If plastic pipe or insulated
fittings are used, run ground wire directly to the metal well
casing or use ground electrode furnished by the power
company.
WARNING
Hazardous voltage.
Can shock, burn, or
cause death.
Ground pump before
connecting to power
supply.

PUMP SERVICE
This centrifugal pump requires little or no service other
than reasonable care and periodic cleaning. Occasion-
ally, however, a shaft seal may become damaged and
must be replaced. The procedure as outlined below will
enable you to replace the seal.
NOTE: Pumps use mechanical seals with a rubber
seat ring or a sealing O-Ring. THESE SEALS ARE
COMPLETELY INTERCHANGEABLE.
CAUTION: 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 screwdrivers (see Figure 4A). Use care not to
scratch motor shaft.
2. Remove seal plate from motor and place on flat sur-
face, face down. Use a screwdriver to push ceramic
seat out from seal cavity (see Figure 4B).
INSTALLATION OF CERAMIC SEAT (Figure 4C)
1. Clean polished surface of ceramic seat with clean
cloth.
2. Turn seal plate over so seal cavity is up, clean cavi-
ty thoroughly.
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 4D)
1. Reinstall seal plate using extreme caution not to hit
ceramic 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
shoulder. This will automatically locate seal in place
and move the sealing washer face up against seat
facing. Reinstall impeller screw (if used).
