between the instructions given in this manual and those
set out by the law in force concerning safety, it is highly
recommended to apply the more restrictive ones.
Maintenance and repair
Only authorized sta is allow to carry out maintenance,
troubleshooting, and repairs. Any maintenance and
repair in progress should be indicated with a specic
sign stating the maintenance condition, and placed on
the control panel of the control unit until completion
of the operation even if temporarily interrupted. All
operations concerning its installation, maintenance or
replacement of components on either the machine or
the control unit should be performed with the system
turned o. Hence, the main switch should be on OFF
(OPEN) and blocked with the safety lock to prevent any
movement in the ON position.
For compressors equipped with INVERTER, before
performing any maintenance job, wait at least 5
minutes after you have disconnected the electricity
supply.
The sta in charge of maintenance, before intervening,
should rst check that the following conditions exist:
– possible tanks under pressure have been discharged.
The sta in charge of maintenance, before intervening
on pneumatic or lubricating systems and specically
on piping, tanks, hoses, and other components under
pressure should correctly reduce the inner pressure
value of the equipment to be investigated to the room
pressure value. Dysfunctional components should be
replaced with others with the same code. If, during
troubleshooting, it should be necessary to carry out the
interventions with the control unit and the machine
supplied, all precautions should be taken as required
by the safety standards to operate under dangerous
voltages and with moving parts. At the end of the
maintenance and troubleshooting interventions, all
disconnected safety devices must be reset. Maintenance,
repair, and troubleshooting should be completed with
the verication of the correct operation of the machine
and of all of its safety devices.
SETTING AT THE CUSTOMER’S EXPENSE

agreements, the following items are normally at the
customer’s expense:
– room preparation (including building work such as
the laying of foundations or canalizations, if required,
etc.);
