Replacement osmotic membrane for RObust Cross 90 reverse osmosis system

How to replace the osmosis membrane (RO 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 faucet.

The system is equipped with FAST&DRY technology, which allows the filter to be replaced without having to interrupt 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 outlet filter counterclockwise.
2. Pull out the used filter towards you.
3. Insert the new filter into the appropriate housing so that the handle is in a horizontal position.
4. Push the cartridge in as far as it will go and turn the handle 90° clockwise.
5. Reset the filter: hold the relevant reset button for 5 seconds. A sound signal (1 second) will be heard, the life indicator will flash purple twice and then light up blue.
6. The system automatically starts flushing the CF and RO filters (takes 5–6 minutes), during which the indicator light flashes red.
7. After this flush, the flushing of the RO and CB filters must be completed manually – open the clean water valve. The indicator light and the indicator on the valve will flash the colour corresponding to 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, meaning the system is ready for use.
