1.1 Introduction

ISA S.r.l. 

employs materials of the best quality and as they enter the company, we constantly 

monitor their storage and the use as part of the manufacturing process to prevent damage, 
deterioration and failure. All manufacturing elements are designed and manufactured in order 
to  guarantee  reliability  and  high  safety  standards.  All  the  equipment  items  are  subjected 
to  a  strict  testing  procedure  before  delivery.  However,  please  bear  in  mind  that  product 
performance  over  time  depends  on  correct  use  and  adequate  maintenance.  This  manual 
contains  the  necessary  instructions  to  maintain  the  equipment's  initial  appearance  and 
functions over time..
 

Note

In order not to compromise the functionality and safety of the equipment, installation and maintenance 
operations that are especially complex have not been documented in this manual and are carried out 
by specialised technicians of the manufacturer.

The  Use  and  Maintenance  Manual  contains  the  necessary  information  for  understanding 
how  the  equipment  works  and  how  to  use  it  properly,  namely:  the  technical  description 
of  the  various  operational  units,  equipment  and  safety  systems,  operations,  how  to  use 
the  instruments  and  the  interpretation  of  any  diagnostics  reports,  main  procedures  and 
information relating to routine maintenance. For correct use of the equipment, the working 
environment should comply with current health and safety standards.

The safety requirements, indications, standards and notes illustrated in the various chapters 
of  this  manual  are  aimed  at  establishing  a  code  of  conduct  and  a  series  of  obligations  to 
be  observed  when  performing  the  various  activities,  in  order  to  create  safe  conditions  for 
personnel, the equipment and the surrounding environment. To ensure the operator's safety, 
the devices of the equipment should be kept in constant working order. This manual is intended 
to illustrate the use and maintenance of the equipment. The operator has a responsibility and 
duty to carefully observe the instructions contained within it. The safety standards reported 
in this document are intended for trained, authorised personnel responsible for:

- transport-
- installation
- operations
- management
- maintenance
- cleaning, decommissioning, and disposal which are the only authorised use of the equipment 
discussed in this manual

Attention

Reading this manual, albeit in full, is no substitute for adequate user experience. Therefore it should 
only be considered a useful reminder of technical features and the main operations to perform.

Warning

The  installers  and  users  are  required  to  read  and  understand  all  the  instructions  contained  herein 
before they carry out any operation on the equipment.
