Align the central pipe in the middle of the container opening and reinsert the central control valve again after removing the cover. Connect the hydraulic connections again.
3.4.2.2Starting Operation
After filling, the filters must be backwashed. For this the complete system is to be connected hydraulically and electrically, and to be switched on at the main switch. The reverse osmosis system must be in the Switched Off operating mode (compare 3.4.3 – 3.4.5). The backwashing is initiated manually with the MANUAL REGEN pushbutton (15/4) and takes approx. 15 minutes. The procedure can be followed on the display of the controller:
- Step 1C: Backwashing; duration approx. 10 min
- Step 2C and 3C: | Without function |
-Step 4C: Initial filtration; duration approx. 3 min Afterwards the filter is ready for operation.
3.4.2.3Backwashing / Regeneration
For cleaning of the filters, the flow direction of the water is reversed so that the settled debris particles are moved to the outlet of the flushing water.
The filters are equipped with different devices for actuation of backwashing:
Activated carbon filter:
- | 1 x per night | Standard: 2:30 a.m. | |
- | Manually: | any time |
|
Media filter: |
|
| |
- | Pressure difference: | upon contamination of the filter | Standard: 1 bar difference |
- | 1 x per night | Standard: 2:00 a.m. | |
- | Manually: | any time |
