General recommendations and precautions

The dryer does not need any specific maintenance. Nevertheless,
before carrying out any maintenance or corrective activity, read the
following recommendations
accordingly:
– Check that the on/off switch S1 is in position O.
– Disconnect pressure sources and vent the internal pressure of
the system before dismantling any pressurized component.
– Use original Atlas Copco spare parts only.
– Check the correct operating after maintenance.
! Filters and valves installed between the compressor, the
dryer and the air consumer may need other maintenance
activities than those mentioned below (e.g. draining the fil-
ters and replacing the filter elements). Refer to the appropri-
ate manual for more information.
