PAGE B -- 9 INSTALLATION
Select pulleys that will match the proper speed ra-
tio; overspeeding the pump may damage both
pump and power source.
Do not operate the pump without the
guard in place over the rotating parts
.
exposed rotating parts can catch cloth-
ing, fingers, or tools, causing severe in-
jury to personnel.
ELECTRICAL CONNECTIONS
If the pump is driven by an electric motor, check
that the electrical service available matches the
motor requirements stamped on the motor name-
plate before connecting a motor to the incoming
power. Check that the motor speed meets pump
specifications.
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.
If the pump is powered by an electric
motor, do not operate a non-explosion
proof motor in an explosive atmo-
sphere. An explosion, which may cause
severe personal injury or death, could
result. Install, connect and operate the
motor in accordance with the National
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
applicable local code, the National or
Local code shall take precedence. All
electrical equipment supplied with the
pump conforms to applicable federal
regulations and national codes in effect
on the date of manufacture.
