qualified to carry out the work involved. If the
personnel in question do not already possess the
necessary knowledge and skill, appropriate training
and instruction must be provided. If required the
operator may commission the manufacturer / supplier
to provide applicable training.

health and safety personnel, and follow all plant safety
requirements and applicable safety and health laws
and regulations.
1.6.3
Safety
action
This is a summary of conditions and actions to
prevent injury to personnel and damage to the
environment and
to equipment.
(For products
used in potentially explosive atmospheres
section 1.6.4 also applies.)
Prevent excessive external pipe load
Do not use pump as
a support for piping.
Do not
mount expansion joints, unless authorized by
Flowserve in writing, so that their force, due to
internal pressure, acts on the pump flange.
Ensure correct lubrication
(See section 5,
Commissioning, startup, operation
and shutdown
.)
Start the pump with outlet valve partly
opened (Unless otherwise instructed at a specific
point in the user instructions). This is recommended
to minimize the risk of overloading at full flow and
damaging the pump
at zero flow.
Pumps may be
started with the valve further open only on
installations where this
situation cannot
occur.
The
pump outlet control valve may need to be adjusted to
comply with the duty following the run-up process.
(See section 5,
Commissioning start-up, operation
and shutdown
.)
Never run the
pump dry.
Inlet valves to be fully open when
pump is
running. Running the pump at zero flow or
below the recommended minimum flow continuously
will cause damage to the pump and seals. Low flow
rates may cause a reduction in pump/bearing life,
