ELECTRICAL
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.
Ground Fault Circuit Interrupter (GFCI) tripping indicates an electri-
cal problem. If GFCI trips and will not reset, have a qualified
electrician inspect and repair electrical system.
Exactly match supply voltage to nameplate voltage! Incorrect voltage
can cause fire or seriously damage motor and voids warranty.
If in doubt consult a licensed electrician.
Voltage:
Voltage at motor must be not more than 10% above or below motor name-
plate rated voltage or motor may overheat, causing overload tripping and
reduced component life. If voltage is less than 90% or more than 110% of
rated voltage when motor is running at full load, consult power company.

Hazardous voltage.
Can shock, burn,
or cause death.
Ground pump before
connecting to
power supply.
