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.
Do not allow pump or any system component to freeze.
To do so will void warranty.

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
Never run pump dry. Running pump with-
out water may cause pump to overheat, damaging seal
and possibly causing burns to 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.

Ground motor before
connecting to electri-
cal 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 electri-
cian.Use wire size specified in Wiring Chart
(below). If possible, connect pump to a sepa-
rate 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 accor-
dance with electrical code requirements. Consult
your local building inspector for information about
codes.
2. Provide a correctly fused disconnect switch for pro-
tection while working on motor. Consult local or
national electrical codes for switch requirements.
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 appli-
cation.
4. Ground the pump permanently using a wire of the
same size as that specified in wiring chart (below).
Make ground connection to green grounding terminal
in pressure switch marked GRD. or . If pressure
switch is disconnected from motor, connect the
grounding lead to bare metal on the motor frame by
a solid copper wire as large as the current carrying
wires.
5. Connect ground wire to a grounded lead in the ser-
vice 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 in
pressure switch. When replacing motor, check wiring
diagram on motor nameplate against diagram above.
If they are not the same, follow the diagram on the
motor.
IMPORTANT: Pump is 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 (above). Do not try to run motor as
received on 115 volt current.
8. Motor has automatic internal thermal overload pro-
tection. 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 confus-
ing, consult a licensed electrician.
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 5A). 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 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 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 5D)
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).
