Replacement carbon block filter cartridge for RObust Cross 90 reverse osmosis system

How to replace the activated carbon filter cartridge (CB filter) in the Robust 90 filtration system?

Replace the filter cartridge regularly according to the purple or red light of the relevant replacement filter life indicator, or the indicator on the water tap.

The system is equipped with FAST&DRY technology, which allows the filter to be replaced without interrupting the water supply. However, for greater safety, we recommend shutting off the water supply during replacement.

To replace the filter cartridge, follow these steps:

1. Turn the CB filter counterclockwise.
2. Pull out the used filter towards you.
3. Insert the new filter into the housing so that the handle is in a horizontal position.
4. Push the cartridge in all the way and turn the handle 90° clockwise.
5. Reset the filter: hold the relevant reset button for 5 seconds. An audible signal (1 second) will sound, the life indicator will flash purple twice and then light up blue.
6. The system will automatically start flushing the CF and RO filters (takes 5–6 minutes), during which the indicator light flashes red.
7. After this flush, you need to manually complete the flushing of the RO and CB filters – open the clean water valve. The indicator light and the valve indicator will flash a color depending on the current water quality.
8. Flushing takes:
   • RO filter: approximately 30 minutes
   • CB filter: approximately 15 minutes
9. Once flushing is complete, the indicator light and the indicator on the valve will light up blue, indicating that the system is ready for use.
