Wiring
Risk of electric shock.
Can shock, burn or kill.
1. To avoid dangerous or fatal electrical shock, turn OFF
power to circuit before working on electrical
connections.
2. Ground motor before connecting to electrical power
supply. Failure to ground motor can cause severe or
fatal electrical shock hazard.
3. 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.

4. Use wire size specified in Wiring Chart (below). If
possible, connect pump to a separate branch circuit
with no other appliances on it.
5. Do not ground to a gas supply line.
6. Wire motor according to diagram on motor nameplate.
If nameplate diagram differs from diagrams above,
follow nameplate diagram.
7. If this procedure or the wiring diagrams are
confusing, consult a licensed electrician.
8. All wiring, electrical connections and system
