15.0 ROUTINE MAINTENANCE
BEFORE CARRYING OUT ANY MAINTENANCE IT IS MANDATORY TO STOP THE COMPRESSOR AND
DISCONNECT IT FROM THE MAIN POWER.
The maintenance jobs described in this Section may be carried out by the user.
The more complex maintenance jobs which require professionally skilled personnel are listed in the Section on
GENERAL MAINTENANCE FOR TRAINED PERSONNEL (See Section. 21.0)
15.1 GENERAL INFORMATION
Routine maintenance must be carried out according to the maintenance schedule affixed to the compressor.

These maintenance intervals are recommended for work environments that are not dusty and are will ventilated.
For particularly dusty environments, double the frequency of maintenance.

BEFORE CARRYING OUT ANY MAINTENANCE IT IS MANDATORY TO STOP THE COMPRESSOR AND
DISCONNECT IT FROM THE MAIN POWER.
MAINTENANCE ON THE ELECTRICAL COMPONENTS CAN ONLY BE PERFORMED BY QUALIFIED
TECHNICIANS OR AUTHORIZED FACTORY PERSONNEL.
CAUTION
When the compressed air cools, part of the moisture sucked in by the compressor condenses. In order to protect the
dryer against the risk of an ice plug forming, it is essential to check regularly that the condensate drains are operating
properly :
On the compressed air storage reservoir and on the filters :
• With a manual drain, drain regularly according to the moisture content of the ambient air.
• With an automatic drain, set the draining cycle accordingly and check that the drain is in good working condition.
This recommendation is also fundamental in a circuit comprising an absorption dryer (risk of saturation of the
alumina).
