Operation
9. Guide the return flow hoses into the flushing agent drums and secure them
against accidental slipping out.
10. Open the return flow again and allow the flushing agent to circulate through
the unit for approx. 3 - 7 minutes, depending on the length of the material
hoses.
11. Set the levers at the mixing unit to “Spray“.
12. Operate the spray gun, until clean flushing agent starts to run out.
13. Set the levers at the mixing unit again to “Circulate“.
14. Regulate the compressed air pressure regulator for the main pump fully
back.
15. Close the compressed air shut-off valve on the maintenance unit.
16. Once both pressure gauges on the high pressure filters show 0 bar, close
the return flow on the mixer with the corresponding ball valve.
17. Stop the flushing agent feed:
➤
For units with suction system take the suction pipes of the material
pumps out of the flushing agent drums.
➤
For units with feed drums drain the flushing agent off through the drain
valves.
➤
For units with feed pumps take the suction pies of the feed pumps out
of the flushing agent drums, close the ball valves and regulate the air
pressure regulators on the feed pumps fully back.
The unit is now fully cleaned and pressure-relieved and thus prepared for a
prolonged decommissioning.
