During operation, always monitor the clogging indicator / differential pressure
gauge on the pre-filter and safety filter so as to know when to replace used
filter elements in good time.
Check the service life of the VME elements using cyclical lab analyses,
especially using MPC values and their trend behavior.
You can view the current operating pressure on the pressure gauge ion
exchange column. The maximum permissible pressure is 8 bar.
