Fire Hazard. Before using pump, check your motor nameplate
for voltage. Your electric supply voltage and the stamped nameplate voltage
must agree. Motors stamped 200 volts or 230 volts, must be used with that
voltage only. Motors stamped with two voltages (for example 230/460 volts),
may be used with either supply voltage. For these motors check connections
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, which require magnetic
starters.
Motors can run in either direction, depending on how they are connected to
the power supply.
To check motors for proper rotation: Remove the motor end cover. This ex-
poses the motor shaft. If hook-up is correct, the shaft will rotate clockwise. If
rotation is not clockwise:
•3 Phase motors: Reverse any two leads to the starter.
•1 Phase motors: See wiring diagram on motor nameplate.
The rotation will now be correct. BE SURE power is off to the motor when
working on electrical connections.
Burn Hazard. Motor normally operates at high temperature and
will be too hot to touch. Before handling pump or motor, stop motor and
allow it to cool for 20 minutes.
