7.1 Maintenance
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 and safety precautions and act accordingly:
• Pull out the power cord or put the on/off switch S1 in the OFF position (whichever is applicable).
• Disconnect all pressure sources and vent the internal pressure of the system before dismantling any
pressurized component.
• Use genuine Atlas Copco spare parts only. Consult the Spare Parts List for part numbers. For
preventive maintenance, dedicated Service kits are available.
• Check for correct operation 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
filters and replacing the filter elements). Refer to the appropriate manual for more
information.
