Safety warnings
Important:
S
Keep this manual with the machine throughout its entire service life.
S
Carefully read this manual before carrying out any operation on the machine.
S
This machine is designed for PROFESSIONAL USE only. Only use the
machine for the purpose for which it is intended. Improper use of the
machine absolves the manufacturer from all liability.
This manual has been compiled to help the final user perform just those oper-
ations which do not require removal of the panels.
All other operations which involve the removal of covers from instruments or
electrical circuit---breakers using special tools must only be carried out by
trained personnel due to the danger of rotating parts or live components.
Operations on the Microprocessor which are not password protected may be car-
ried out by the final user.
Operations on the Microprocessor which are password protected should be car-
ried out by a qualified technician using the passwords given on the last page of this
manual. This page may be detached and retained by those persons authorised to
service the machine.
Each machine is equipped with an electric disconnect device (main switch) which
allows the operator to work on the machine in absolute safety.
This device must
always be used to disconnect the mains supply to avoid any risk of danger during
maintenance work (electric shocks, scalding, automatic start---up, moving parts
and remote control).
Before servicing the dryer always make sure the compressed air circuit is
depressurised.
When requesting technical assistance or ordering spare parts, always quote the
model and serial number on the identification plate mounted externally on the
unit. In particular to identify the model and serial number of the control , see the
nameplate on the rear of the Microprocessor Control. To identify the software
version, refer to the Maintenance Menu.
IMPORTANT:
This manual is subject to modification. For the most comprehen-
sive and up---to---date information, the user is therefore required to consult the
manual supplied with the machine.
