PAGE B - 5 INSTALLATION
but fastening hardware may have loosened during
shipment. It is imperative that alignment be
checked after the pump and piping are installed,
and before operation. Adjustments may be made
by loosening the securing hardware and shifting or
shimming components as required.
To check coupling alignment, use a feeler gauge or
taper gauge between the coupling halves every
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 side. When the straightedge rests evenly on
both halves of the coupling, the coupling is in hori­
zontal parallel alignment. If the coupling is
misaligned, use a feeler gauge between the cou­
pling and the straightedge to measure the amount
of 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
power, check that the electrical service available
matches the pump motor requirements stamped
on the motor nameplate.
The electrical power used to operate
this pump is high enough to cause inju­
ry or death. Obtain the services of a qu­
alified electrician to make all electrical
connections. Make certain the pump
and motor are properly grounded; never
use gas pipe as an electrical ground. Be
sure that the incoming power matches
the voltage and phase of the motor be­
fore making motor connections. Do not
run the pump if the voltage is not within
limits.
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.
Refer to the following motor data before making
electrical connections.
