Electrical / Service
Before using pump, check your motor
nameplate for voltage. Your electric supply voltage and
the stamped nameplate voltage must agree. Motors
stamped 200 volts only or 230 volts only, must be used
with that voltage only. Motors stamped with two volt-
ages (for example 230/460 volts), may be used with
either supply voltage. For these motors check connec-
tions against wiring diagram on motor nameplate and
make any changes necessary to agree with your supply
voltage. If in doubt, call a licensed electrician. Incorrect
voltage will cause serious damage to the motor.
Some models are equipped with three phase motors.
Three phase motors require magnetic starters.
To check motors for proper rotation: Remove the motor
end cover. This exposes the motor shaft. If hook-up is
correct, the shaft will rotate clockwise. If rotation is not
clockwise, see motor nameplate for hookup information.
BE SURE power is off to the motor when working on
electrical connections.
Motor normally operates at high tempera-
ture and will be too hot to touch. Before handling pump
or motor, stop motor and allow it to cool for 20 minutes.

*A Fusetron is recommended instead of a fuse in any motor circuit.
IMPORTANT: BE SURE lead wire opening on end of motor is fully sealed when conduit or a pressure switch is not
used. Failure to seal it properly will allow dirt, rain, bugs, etc. to enter back compartment of motor through conduit
opening and cause malfunction.

SERVICE
Never run pump dry. Running pump with-
out water may cause pump to overheat, damaging seal
and possibly causing burns to persons handling pump.
Fill pump with water before starting.
Never run pump against closed discharge.
To do so can boil water inside pump, causing hazardous
pressure in unit, risk of explosion and possibly scalding
persons handling pump.
PRIMING THE PUMP
A tee installed in the discharge opening of the pump, and
provided with a priming plug at the top position, will
enable you to fill the pump with liquid. Once filled and
the priming plug replaced, the pump will prime. The
pump should prime itself time after time, as long as the
built-in check valve functions.
MAINTENANCE
Little or no maintenance to pump is required other than
possible replacement of shaft seal after a reasonable peri-
od of operation (see Page 10).
Lubricate motor according to motor manufacturer's in-
structions. Periodic greasing is required for most motors.
PUMP STORAGE
Drain pump to prevent freezing.
Keep motor dry and loosely covered. Do not wrap with
plastic sheeting; trapped moisture could cause corrosion
or insulation deterioration.
NOTE: A good rust inhibitor in the liquid end of cast iron
pumps is recommended to prevent excessive corrosion.
