1.1
Purpose of this chapter
Chapter 1, PREFACE, provides the general safety rules and information on structure of the
manual and how to use it.
1.2 Safety
rules
Those working on this pump must be aware of and observe at all times the general and
specific safety rules that are listed below.
Failure to observe the safety rules may result in harm being caused to personnel and/or
damage to pump components.
With a view to preventing the risks deriving from operation of the pump, suitable protection
devices must be installed, in accordance with the applicable national safety rules.
All pump installation and maintenance work is to be performed with the electric power line
not connected.
Staff responsible for installation, maintenance and operation of the pump must realize that
knowing and applying the safety precautions is an integral part of their work. In particular,
those responsible for the following:
•
Putting the pump into service, or managing its operation
;
•
Performing different types of work on the pump,
especially regarding maintenance,
control and repair of any of the pump’s components before it is switched on, during
operation, or even after it is switched off;
must read the documentation carefully so as to be aware of the potential dangers
that they may encounter in the course of their work
, both as regards operation and
correct use of the safety devices.
When installing or replacing a part, take great care. Pay special attention to the three-phase
motor, where an inversion of polarity causes inversion of the direction of rotation of the
pump with consequent possibilities of mechanical damage.
Further safety rules will be found in the chapters on specific operations.
