- Operating instructions for the individual components must be known.
Procedure:
1. Connect compressed air supply.

3. Set a low pressure (approx. 0.5 MPa; 5 bar; 73 psi) on the pressure controllers for the 3
pumps.
4. First of all, vent and clean the fl ushing pump with the cleaning agent via the return ball
valve.
5. Select fl ushing valves AS and BS with the control with component „AS" or „BS". Press
