5 Service and Maintenance
5.1 Maintenance
The SRZ* does not require regular maintenance.
For best performance, however, we recommend a recalibration every year if operated 24 hours a day
or every 2 years if the unit is running less than 24 hours a day.
When used with aggressive or abrasive media the SRZ* should be checked and recalibrated even
more often.
If there is no flow over a longer period, the SRZ* should be emptied and cleaned. This is especially
important if curing media like paints are measured.
For recalibration and test, please contact your nearest dealer or directly KEM.
