The recommended change cycles are based on empirical values for dosing applications.
The empirical values are based on different material properties, pressure conditions and
dosing settings. Depending on the material used, the required change cycles may differ from
the recommended cycles.
Ambient conditions, such as temperature and humidity, may affect the change cycles.
WARNING
Maintenance and cleaning work may only be carried out when the machine has been shut
down safely and secured against unauthorised restarting. Otherwise, serious injuries may
