3.4 – STOPPING WITH WINTERING PROCEDURE : CLEANING + PRESERVATION (LONG TIME STOP)
1. Use the AQUA-BASE wintering kit, which contains 1 cleaning solution + 1 preservation solution + filter 5µ.
2. Rinse the membranes with fresh water as described in chapter (See 3.2 previous page).
Cleaning
3. Fill the auxiliary tank (or bucket) with 10 litres of dechlorinated fresh water.
4. Prepare the cleaning solution 752003-MC11 (see 752037-EXP10) by mixing it in the auxiliary tank (or bucket).
5. Check the cleaning pipes connexions (B4) and (A3) in outlet/inlet of the auxiliary tank (or bucket) and open the cleaning valve (11)
to cleaning position.
6. Position the inlet valve (1) so as to take water from the auxiliary tank (bucket).
7. Open the air bleed valve (7) of the hydraulic amplifier (6).
8. Put the production valve (12) to reject position.
9. Put the unit ON by opening the main breaker on "ON" (1), operating in closed circuit.
10. Let the unit works in closed circuit for 20 minutes.
11. After this time, turn OFF the unit by closing the main breaker on "OFF" (0).
12. When the unit stops, empty the solution out of the auxiliary tank (or bucket) and clean it with fresh water.
13. Position the cleaning valve (11) in the reject position.
14. Rinse the membranes as described in chapter 3.2 previous page.
15. Take 10 liters of water from the principal tank, fill the auxiliary tank (bucket) (without chlorine because can damage the membrane).
16. Prepare the cleaning solution 752003-MC3 (see 752037-EXP10) by mixing it in the auxiliary tank (or bucket).
17. Open the cleaning valve (11) to cleaning position.
18. Put the unit ON by opening the main breaker on "ON" (1), operating in closed circuit.
19. Let the unit works in closed circuit for 20 minutes.
20. After this time, turn OFF the unit by closing the main breaker on "OFF" (0).
21. When the unit stops, empty the solution out of the auxiliary tank (or bucket) and clean it with fresh water.
22. Position the cleaning valve (11) in the reject position.
23. Rinse the membranes as described in chapter 3.2 previous page.
Preservation
24. Fill the auxiliary tank with 10 litres of fresh water and add the AQUA-BASE preservation solution BIOCIDE, Ref. 752002-20 and mix.
If the unit is to be stored at a temperature below 0°C, 20% of AQUA-BASE ANTI-FREEZE® ref.752004 must be added to the
preservation solution, during its preparation.
25. Position the inlet valve (1) so as to take water from the auxiliary tank (bucket) and direct it towards the LP pump.
26. Open the air bleed valve (7) of the hydraulic amplifier (6).
27. Position the cleaning valve (11) in the reject position.
28. Put the production valve (12) to reject position.
29. Put the unit ON by opening the main breaker on "ON" (1). Check the level of water in the auxiliary tank (or bucket).
30. Turn OFF the unit by closing the main breaker on "OFF" (0) before the auxiliary tank (or bucket) is empty to avoid air accumulation.
31. When pump is stopped, shut the hull valve (V0) and check valves position (initial position).
32. Whatever their condition, empty the filter (4) to avoid any bacteriological proliferation and if needs be, replace the filtration cartridge
(If you put the old cartridge back, wait until they are dry).
33. It is necessary that water remains in the membrane, make sure it cannot freeze (in the case of a possible risk, add to the storage
solution, the anti-freeze solution Ref. 752004 ( See chapter 3.3 previous page).
If the unit is to be stored at a temperature below 0°C, 20% of AQUA-BASE ANTI-FREEZE® ref.752004 must be added
to the preservation solution, during its preparation.
NB :
PRESERVATION OF THE PROCON PUMP : It is necessary to preserve the PROCON pump (with glycerine), for this, refer to the
Technical Note NT0809 (at the end of the technical handbook).
