The prescribed service and maintenance intervals must be maintained in order to warrant a fault-free operation.

The application timeframe for the following points cannot be prescribed. Periodic service, maintenance and cleaning of the equipment depends
upon the level of dirt and contamination. These interval guidelines apply to standard RAC systems under normal operating conditions. With
heavy contamination or 24h operations, the intervals should be set at least 1 level shorter.
