7 Maintenance
7.1 Servicing
FAFNIR devices are generally maintenance-free.
Only the probes in light liquid separators must be cleaned regularly every 6 months. This can
be done e. g. during the prescribed six-monthly maintenance of light liquid separators.
7.2 Return shipment
Before returning any FAFNIR devices, the Return Material Authorization (RMA) is required.
Please contact your Account Manager or the Technical Support for more information on re-
turning goods.
