Electrical 7
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 voltages (for example 230/460
volts), may be used with either supply voltage. For these motors check con-
nections 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 clock-
wise. If rotation is not clockwise, see motor nameplate for hookup informa-
tion. BE SURE power is off to the motor when working on electrical con-
nections.
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.

*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 switch malfunction.
