Installation 5
LOCATION OF UNIT
Locate the pump as near the liquid source as possible, using a short, direct
suction pipe. Keep the static suction lift (vertical distance between the cen-
ter line of the pump and the liquid level) to a minimum. Mount the pump
on a solid, level foundation, which provides a rigid and vibration-free sup-
port. It should be located where the unit is readily accessible for service
and maintenance. The pump should be protected against flooding and
excessive moisture.
PIPING
Both suction and discharge piping should be independently supported at
a point near the pump to avoid strains being placed on the pump. Start all
piping at pump to avoid strains left by a gap at last connection.
SUCTION PIPING
The suction pipe must be kept free of leaks. The suction pipe must have a
gradual slope upward to the pump. Avoid any fittings which may cause an
air trap. On units that have a suction fitting, a check valve is a built-in fea-
ture and no foot valve is required.
DISCHARGE PIPING
A gate valve and union should be installed in the discharge line. For remov-
al of the pump for service, close the gate valve, and disconnect at union.

Electrical 6
Disconnect power at service panel before connecting motor.
Single phase motors come factory wired for 230 volt operation. Do not
alter wiring in single phase motors. Match motor voltage to power supply
voltage. Do not connect three phase motors to single phase power supply
or single phase motors to three phase power supply.
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 seriously damage motor and
voids warranty. If in doubt consult a licensed electrician.
Use wire size specified in Wiring Chart. If possible, connect pump to
a separate branch circuit with no other appliances on it.
WIRING
Step 1. Install, ground, wire and maintain this pump in accordance with your
local electrical code and all other codes and ordinances that apply.
Consult your local building inspector for local code information.
Step 2. Ground the pump permanently using a wire of size and type speci-
fied by local or National Electrical Code.
Do not ground to a gas supply line.
Step 3. Connect ground wire first. Connect to ground first, then to green
grounding terminal provided (identified as GRD or ). Make
ground connection to this terminal. Do not con-
nect motor to electrical power supply until unit is permanently
grounded; otherwise serious or fatal electrical shock hazard may be
caused.
Step 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 elec-
trode furnished by the power company.
WARNING
Hazardous voltage.
Can shock, burn, or
cause death.
Ground pump before
connecting to power
supply.

Electrical 7
Before using pump, check your motor nameplate for volt-
age. Your electric supply voltage and the stamped nameplate voltage must
agree. Motors stamped 200 volts only or 230 volts only, must be used with
that voltage only. Motors stamped with two voltages (for example 230/460
volts), may be used with either supply voltage. For these motors check con-
nections against wiring diagram on motor nameplate and make any chang-
es necessary to agree with your supply voltage. If in doubt, call a licensed
electrician. Incorrect voltage will cause serious damage to the motor.
Some models are equipped with three phase motors. Three phase motors
require magnetic starters.
To check motors for proper rotation: The shaft can be seen through the
motor - pump adapter bracket. A mark can be made on the shaft to make
it easier to notice rotation. Jog the motor (start it briefly) and note the rota-
tion. It should rotate clockwise when viewed from the motor-end. If rotation
is not clockwise, see motor nameplate for hookup information. BE SURE
power is off to the motor when working on electrical connections.
Motor normally operates at high temperature and will be too
hot to touch. Before handling pump or motor, stop motor and allow it to
cool for 20 minutes.

* Time delay fuse or circuit breakers are recommended in any motor circuit.
IMPORTANT: BE SURE lead wire opening on end of motor is fully sealed
when conduit or a pressure switch is not used. Failure to seal it properly
will allow dirt, rain, bugs, etc. to enter back compartment of motor through
conduit opening and cause switch malfunction.

Service 8
Never run pump dry. Running pump without water may
cause pump to overheat, damaging seal and possibly causing burns to per-
sons handling pump. Fill pump with water before starting.
Never run pump against closed discharge. To do so can boil
water inside pump, causing hazardous pressure in unit, risk of explosion
and possibly scalding persons handling pump.
PRIMING THE PUMP
A tee installed in the discharge opening of the pump, and provided with a
priming plug at the top position, will enable you to fill the pump with liq-
uid. Once filled and the priming plug replaced, the pump will prime. The
pump should prime itself time after time, as long as the built-in check valve
functions.
MAINTENANCE
Little or no maintenance to pump is required other than possible replace-
ment of shaft seal after a reasonable period of operation (see Page 10).
Lubricate motor according to motor manufacturer’s in-structions. Periodic
greasing is required for most motors.
PUMP STORAGE
Drain pump to prevent freezing.
Keep motor dry and loosely covered. Do not wrap with plastic sheeting;
trapped moisture could cause corrosion or insulation deterioration.
NOTICE: A good rust inhibitor in the liquid end of cast iron pumps is rec-
ommended to prevent excessive corrosion.
PUMP START-UP AFTER STORAGE
Replace all drain plugs and close all drain valves in system.
Be sure all connections are tightly sealed.
After initial check is made, fill pump according to “Priming the
Pump,” above.
SHAFT SEAL REPLACEMENT
IMPORTANT: The highly polished and lapped faces of the seal are easily
damaged. Follow instructions and handle the seal with care.

INSTALLING NEW SEAL
Step 1. IMPORTANT: Seal faces are highly polished and lapped. Handle
with care. Any mar, nick or scratch on seal face will cause it to
leak. BE SURE to install with polished faces toward each other.
Step 2. Clean polished surface of ceramic seat with clean cloth.
Step 3. Wet O-Ring around ceramic seat with liquid soap.
Step 4. Press stationary (ceramic) half of seal into cavity firmly and squarely
with thumb pressure. If it does not seal properly, remove and place
face up on bench. Re-clean adapter/seal plate cavity. Seal should
now seat correctly.
Step 5. If seal does not seat after recleaning adapter/seal plate cavity, place
a cardboard washer over polished face of seal and carefully press
into place using a piece of 1” standard pipe as a press. (Figure 6).
NOTICE: BE SURE you do not scratch seal face.
Step 6. Dispose of cardboard washer and recheck seal face to be sure it is
free of dirt, foreign particles, scratches and grease.
7. Inspect shaft and shaft sleeve to be sure they are clean.
8. Re-install O-Ring, shaft sleeve and slinger (Key No. 4) on shaft.
NOTICE: A small amount of grease or Never-Seez under shaft
sleeve will help prevent shaft and sleeve from freezing together
when pump is in service.
9. Remount adapter/seal plate to motor, being careful not to scratch
seal face.
Step 10. Apply liquid soap to inside diameter and outside face of rubber
drive ring on rotating half of seal.
Step 11. Slide seal assembly onto shaft sleeve (sealing face first) far enough
so that seal spring is located on shaft sleeve. NOTE: Be careful not
to nick carbon seal face when passing it over end of shaft sleeve.
Step 12. Slide impeller and gaskets (Key Nos. 12 and 11) onto shaft with
key (Key No. 3) in position. Be sure to maintain proper order as
shown in Exploded View, Page 11.
Step 13. Install washer, gaskets, and impeller screw (Key Nos. 14, 15, 16,
17) on end of shaft and tighten screw until it is snug. This should
locate seal in place and bring seal faces together.
Step 14. Re-install motor, adapter and impeller assembly on volute, using
new gasket (Key No. 7).
Step 15. Re-install motor hold-down bolts.
Step 16. Check all bolts for tightness.
Step 17. Pumps below water level: Close drains; open isolation valves to
fill pump. Pumps above water level: Prime pump. Open isolation
valves if they were closed at disassembly.
Step 18. When pump is full, close air vents.
Step 19. Reconnect power to pump and system is ready for operation.
