WARNING
Follow all local electrical and safety codes, as well
as the National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA).
This product contains chemicals known to the State of
California to cause cancer and birth defects or other
reproductive harm.
Do not use to pump flammable or explosive fluids
such as gasoline, fuel oil, kerosene, etc. Do not use
in flammable and/or explosive atmospheres.
Install pressure relief valve in discharge pipe.
Release all pressure on system before working on
any component.
CAuTION
Wire motor for correct voltage. See Electrical section
and motor nameplate.
Ground motor and controls before connecting to
power supply.
Follow wiring instructions in this manual when
connecting to power lines.
Protect power cable from nicks or cuts from sharp
objects or scraping on well casing when lowering
pump into well. Do not allow it to come into contact
with oil, grease, hot surfaces or chemicals.
The motor voltage and phase indicated on the motor
nameplate should be checked against the actual
electrical supply. Check your power source. Check
electrical supply for correct fusing, wire size, and
adequate grounding and transformer size.
The power supply for a submersible pump should be
a separate circuit, independent of all other circuits. It
must be equipped with a fuse box of ample capacity.
Shut off power source when voltage drops 10% below
rated voltage of motor.
For fire protection, power supply should be free of any
building, preferably on a direct line from transformer.
In event of fire, wires will not be destroyed and water
supply not cut-off.
SAFETY INFORMATION
NOTE: Install all electrical equipment in protected area to provide adequate ventilation for pressure switch and
controls to prevent moisture damage to components.
NOTE: Install pump, pressure tank, pitless adaptor or well seal in accordance with state and local plumbing
codes.
PREPARATION
Before beginning installation of product, make sure
all parts are present. Compare parts with package
contents drawing. If any part is missing or damaged,
do not attempt to assemble the product. Contact
customer service for replacement parts.

Check cable size against Submersible Wire Size
Chart A. For 3-wire plus ground models, motor
and control box voltage must match. Submersible
power cable must be UL listed for submersible pump
applications. For Canadian installations, type RWU,
TWU, SGOW or SWOW power supply cable is
recommended. Cable is selected for the maximum
pump setting plus the offset distance to the service
entrance.
IMPORTANT: Use of wire sizes smaller than those
specified in the chart will cause low starting voltage,
may cause early pump failure and will void the
warranty. Larger wire sizes may always be used
for better economy of operation. Be sure voltage
at pressure switch or fuse is between the following
limits:
115V Rated - Between 104 & 127 volts
230V Rated - Between 210 & 250 volts
The National Electric Code (NEC 250-43) requires
a separate ground wire be run down the well to the
submersible pump and connected to all exposed
metal parts of the pump and motor. Refer to the
most recent National Electric Code (NEC) Article 250
(grounding) for additional information.
NOTE: All wiring should be done by a qualified
electrician.
wARNING: 3-wIRE SubMERSIblES ONlY: This submersible pump must be wired
directly to a control box of the same horsepower and voltage rating in order to work properly.
