In step 5, clean all the pneumatic components, i.e. the pneumatic block and
the internal reference tank are flushed with water. This is done to ensure that no
detergents remain in Sartocheck
If you have not installed the connections in accordance with the diagram and the
procedure has already started, we recommend that you cancel cleaning and restart.
The pneumatic components can be damaged or their function impaired by improper
connection. Improperly connected tubing can also impair the effectiveness of the
cleaning procedure. Therefore, cleaning should be restarted.
The duration of the individual cleaning steps is predefined at 10 min per step.
If it is necessary to change the time for the cleaning and drying steps, this can be
done within the Service Menu.
