5.4.6 PRESSURE RELIEF VALVE
Although the pressure relief valve has a
reset ring at the cap,
DO NOT
test the
pressure relief valve by pulling on the reset
ring. The pressure relief valve requires no
safety testing. If faulty, replace the valve
(refer to symptoms and recommendations
given in the Troubleshooting Guide in
Section 6
).
5.4.7 REPLACING THE DRIVE COUPLING
With proper care of the machine, the drive
coupling should normally last indefinitely.
However, it may become worn or ruptured
and need to be replaced. To replace the
drive coupling, order replacement element
no. 277764, and follow the procedure below.
IMPORTANT
Reason(s) for shutdown should be
investigated before pressing reset.
WARNING
Before performing maintenance:
Shut down machine, relieve all system
pressure and lock out all power, as per the
Safety Section of this manual.
NOTE THAT THE SYSTEM CAN BE
STARTED REMOTELY:
Always clearly tag the start-up
instrumentation against accidental system
start-ups during maintenance.
NOTE
Alignment checks should not be necessary,
as the machine is factory-set. However,
when performing a coupling element
replacement, proper sizing and offset
measurements must be properly set and
checked to avoid damage to machine and/or
coupling.
IMPORTANT
It is important to remember that the drive
coupling contains wear elements that will
eventually fail. Operator must ensure that the
assembly is enclosed to avoid injury in case
of a failure.
