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 electri-
cal 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 war-
ranty. If in doubt consult a licensed electrician.
Use wire size specified in Wiring Chart (Page 8). If possible, con-
nect pump to a separate branch circuit with no other appliances
on it.
Wire motor according to diagram on motor nameplate. If name-
plate 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.

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.
Connect power supply wires to L1 and L2. For 3-phase
motors, or if motor does not match these pictures, fol-
low the connection diagram on the motor nameplate.
