90_. The coupling is in alignment when the hubs
are the same distance apart at all points.
To check parallel adjustment, lay a straightedge
across both coupling halves at the top, bottom and
sides. The horizontal parallel adjustment is correct
when the straightedge rests evenly on both halves
of the coupling at all points. Use a feeler gauge be-
tween the coupling to measure any misalignment.
Do not operate the pump without the ec-
centric and coupling guards in place
over the rotating parts. Exposed rotat-
ing parts can catch clothing, fingers, or
tools, causing severe injury to person-
nel.
ELECTRICAL CONNECTIONS
Before connecting the motor to the incoming pow-
er, check that the electrical service available
matches the pump motor requirements stamped
on the motor nameplate.
The pump must be operated in the direc-
tion indicated by the arrow on the gearbox
and on the accompanying decals. Reverse
rotation could cause pump components to
be destroyed.
Only install an explosion proof motor in an explo-
sive atmosphere.
Be sure the motor is compatible
with the intended application.
Install and operate only an explosion
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.
