INSTALLATION
CONNECTION DIAGRAM FOR DUAL VOLTAGE,

SINGLE-PHASE MOTORS

Your dual-voltage motor's terminal board (under the motor end
cover) will match one of the diagrams below. Follow that diagram
if necessary to convert motor to 115 Volt power. Connect power
supply wires to L1 and L2. For 3-phase motors, or if motor does not
match these pictures, follow the connection diagram on the motor
nameplate.
THE MOTOR IS SET FOR 230 VOLTS WHEN SHIPPED.
To change the motor to use 115 volts:
1. Turn off power
2. Remove the back motor cover.
3. Use a screwdriver or 1/2" wrench and turn the voltage
selector dial counterclockwise until 115 shows in the
dial opening.
4. Reinstall the motor cover.
Hazardous voltage. Can shock, burn, or cause
death. Disconnect power to motor before working on pump or
motor. Ground motor before connecting to power supply.

WIRING
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 damage motor and voids
warranty. If in doubt consult a licensed electrician.
Use wire size specified in Wiring Chart (Page 5). 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 ABOVE,
FOLLOW NAMEPLATE DIAGRAM.
1. Install, ground, wire and maintain your pump in compliance
with the National Electrical Code (NEC) in the U.S., or the
Canadian Electrical Code (CEC), as applicable, and with all
local codes and ordinances that apply. Consult your local
building inspector for code information.
2. Provide a correctly fused disconnect switch for protection
while working on motor. For switch requirements, consult
your local building inspector for information about codes.
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 application.
4. Ground the pump permanently using a wire of the same size
as that specified in Wiring Chart (Page 5). Make ground
connection to green grounding terminal under motor
canopy marked GRD. or
5. Connect ground wire to a grounded lead in the service
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 L1 and L2
under motor canopy. When replacing motor, check wiring
diagram on motor nameplate against Figure ##. If the motor
wiring diagram does not match either diagram in Figure 3,
follow the diagram on the motor. IMPORTANT: 115/230 Volt
single phase models are 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. Do not try
to run motor as received on 115 volt current.
8. Motor has automatic internal thermal overload protection.
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. Always consult a licensed electrician for clarification of this
procedure or the wiring diagrams.
