V08 en, SCC - 60 -
Function during CleanJet+Care SCC
Sequence of Cleanjet Program Light, Medium, Strong with scaled steam generator
The Cleanjet process ist divided into 3 groups:
Component test
Cleanjet Phase
Care Phase
Component test
1. SC pump is activated until level electrode senses low water.
2. Y1 lling solenoid is activated (control by CDS)
3. Y3 moistening solenoid is activated (control by CDS)
4. Y4 Care solenoid is activated (control by CDS)
5. Y1-Y3-Y4: all solenoid valves are switched o
Cleanjet Phase
6. M7 drain valve closes
7. Y3 moistening solenoid brings water into the quenching box (CDS controlled)
(In case the moistening nozzle is blocked water is brought by quenching solenoid Y2 (time based)
- depending on CJ step)
8. M6 Cleanjet pump pumps water through the cabinet (water ow is detected by amp draw of motor)
9. M7 drain valve opens and dirty water is released.
(steps 6 - 9 are repeated dependent on cleanjet program light, medium or strong)
Care Phase
10. Y4 Care solenoid lls care container twice with water. The water with the dissolved care chemical is
pumped each time into the steam generator with the care pump M12.
11. M7 drain valve closes.
12. Y1 lling solenoid lls the steam generator with water up to the level electrode.
13. M4 SC pump is activated for a few seconds to pump some of the content of the steam
generator into the quenching box.
14. Y1 lling solenoid rells the steam generator higher than the level electrode.
15. Y3 moistening solenoid tops up the quenching box.
16. SSR - water in the steam generator is preheated up to 80°C (176°F)
17. M6 Cleanjet pump pumps water (rinse) through the cabinet.
18. M7 drain valve opens and water is released.
19. M4 SC pump empties steam generator.
20. Steam generator is ushed several times, cabinet will be steamed for a few minutes.
21. Cabinet will be dried out with hot air.
Depending on real steam production time or when the scale deposit inside the steam generator is below 4%,
only a small number of Care Tabs is indicated and steps 12, 14, 16 and 19 are skipped (no descaling of steam
generator, shorter CleanJet+Care process). The entire content of the steam generator is pumped into the quench-
ing box.
If the scale deposit is above 4%, more Care tabs are requested (depending on unit size), all steps are active and
the steam generator will be descaled.
Reaching 20% the customer will be informed that descaling is urgently needed. This information will be active for
2 minutes.
