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 necesary to convert motor
to 115 Volt power.

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 6). 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.
Step 1. Install, ground, wire and maintain this pump in accordance with
electrical code requirements. Consult your local building inspector
for information about codes.
Step 2. Provide a correctly fused disconnect switch for protection while
working on motor. Consult local or national electrical codes for
switch requirements.
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.
