General Safety
IMPORTANT INSTRUCTIONS BEFORE INSTALLATION
Failure to follow these instructions may cause serious bodily injury and/or property damage.
Warranty void if product modified, drilled, painted,
or altered in any way; if used to pump hot water,
or to pump liquids other than water (such as but
not limited to chemicals, salt water, fertilizers,
flammable liquids, herbicides, mud, tar, cement,
wood chips); or otherwise abused.
1. Before installing or servicing your pump, BE CERTAIN pump
power source is disconnected.
2. All installation and electrical wiring must adhere to state
and local codes and must be complete before priming the
pump. Check with appropriate community agencies, or
contact your local electrical and pump professionals.
3. Pump should be installed in a dry, convenient location
which is close to the well and provides ample space for
installation and servicing the well. A dry basement, pit, or
utility room is an excellent choice when allowed by law.
4. CALL AN ELECTRICIAN WHEN IN DOUBT. Pump motor
should be connected to a separate electrical circuit directly
from main switch. There must be a fuse box or circuit
breaker installed in this line. Plugging into existing outlets
may cause low voltage at motor, resulting in blown fuses,
tripping of motor overload, or burned-out motor. Refer
to electrical diagrams on following page for electrical
connections.
5. It is mandatory that a permanent ground connection be
made from the pump motor to the grounding bar at the
service panel. Do not connect pump motor to a power
supply until permanently grounded. For maximum safety,
ground the pump motor to a circuit equipped with a fault
interrupter device.
6. Motor Grounding Instructions: WARNING: Reduced risk
of electric shock during operation of this pump requires
the provision of acceptable grounding. Caution: Failure to
ground this unit properly may result in severe electrical
shock. If the means of connection to the supply-
connection box is other than grounded metal conduit,
ground the pump motor back to the service by connecting
a copper conductor, at least the size of the circuit
conductors supplying the pump motor, to the grounding
screw provided within the wiring compartment. NOTE:
N.E.C. requires pumps be grounded at installation.
CAUTION
Pump must be primed! Make sure pump is full of water before
running! Failure to do so will cause damage to mechanical seal,
leakage and flooding!
Never run pump against closed discharge valve! To do so can
cause high temperatures, pump damage, personal injury and
property damage!
Hazardous voltage! Can shock, burn or cause death. Read
instructions before installing!
To avoid dangerous or fatal shock hazard, turn off
power and ground motor before connecting motor to
electrical power supply!

Do not ground to a gas supply line!
Match supply voltage to nameplate voltage. Wrong voltage can
cause fire or motor damage and voids warranty. If in doubt,
consult a licensed electrician.
Pump may be HOT to touch. Use caution!
7. Voltage of power supply must match the voltage of the
pump. Be sure that the voltage selector in the back of
the motor matches the supply voltage. Failure to match
the selector to the supply voltage will damage the motor
and void the warranty. Both types of motors may be wired
for either 115V or 230V. If the motor is converted to 115V,
electrician should ensure that electrical and power leads
can handle the higher amps.
8. During installation, cover well to prevent foreign matter
from contaminating the well or later damaging the pump
during operation. Test well water for purity. Chlorination
may be necessary. Check local health department for
proper testing and recommendations.
9. Hand pump new wells until clear. Sand or other sediment
will seriously damage the pump.
10. The following may cause severe damage to pump and/or
piping and will void warranty:
• Failure to protect pump and piping against below-freezing
temperatures.
• Pumping chemicals or corrosive liquids.
• Running the pump dry. Follow priming instructions on pages
5 or 8, depending on the installation.
11. Do NOT use extension cords.
12. Do NOT pump gasoline or other flammable liquids.
13. Do NOT use this pump in or near a swimming pool, lake
or pond.

C. Install Your Pump
1. Install a Shallow Well Pump (123357)
2. Install a Deep Well Pump (123355, 123353)
Process A. Knowing the Depth of
Your Welll
Shallow wells are less than 25 feet to water; deep wells are up
to 70 feet to water. Tie a small but heavy weight to the end of a
piece of string (be sure there is enough string; some wells are
very deep). Lower the weight into the well until it reaches the
bottom. Take up the slack and mark the string at ground level.
Pull the weight out of the well and measure from the bottom of
the weight to the ground level mark. This is the depth of your
well. Subtract five feet from the depth of your well. This number
should not exceed the maximum rated depth for your pump. If it
does, it will greatly hinder or prevent the proper operation of the
pump.
