During maintenance or repair on the regeneration valves, special attention must be
paid to the connections of:
the pilot air flexibles to these valves
the electric cabling between the valves and cubicle
Wrong connections may cause the working pressure to be fed to the regeneration
silencer which may generate a high noise peak.
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.
