INSTALLATION

ELECTRICAL CONNECTIONS

Before connecting a motor to the incoming power,
check that the electrical service available matches
the pump motor requirements stamped on the mo­
tor nameplate.

If rotation is incorrect on a three‐phase motor, have
a qualified electrician interchange any two of the
three phase wires to change direction. If rotation is
incorrect on a single‐phase motor, consult the lit­
erature supplied with the motor for specific instruc­
tions.

The electrical power used to operate the
pump is high enough to cause injury or
death. Obtain the services of a qualified
electrician to make all electrical con­
nections.

Do not install and operate a non‐explo­
sion proof motor in an explosive atmo­
sphere. Install, connect, and operate
the motor in accordance with The Na­
tional Electric Code and all local codes.
If there is a conflict between the instruc­
tions in the manual accompanying the
unit and The National Electric Code or
the applicable local code, The National
or local code shall take precedence.
