Function during CleanJet+Care
Sequence of Cleanjet Program Light, Medium, Strong
Component test
1. SC pump is activated until level electrode senses low water.
2. Y1 filling 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 off, CDS shall not send any pulses.
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 either by quenching solenoid Y2
(time based) or pumped from the steam generator into the quenching box (time based)
- depending on CJ step)
8. M6 Cleanjet pump pumps water through the cabinet (water flow 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 fills 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 filling solenoid fills 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 filling solenoid refills 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 flushed several times, cabinet will be steamed for a few minutes.
