Pressure monitoring
There are no pressure gauges in the RObust Mini product; they need to be installed additionally to check the pressure in the system.
Pre-filtration cartridges
Replace pre-filters after 8,000 liters of water filtration or at least every 3 months.
- If the pressure after the pre-filters drops below 1 bar, the cartridges may be clogged.
- Delaying replacement may damage or reduce the lifespan of the membrane.
Reverse osmosis membrane
With a significant drop in system performance, replacement of reverse osmosis membranes is required. Replace after filtering 24,000 liters or at least once per year if filtration speed decreases.
Post-filtration cartridge
Replace if taste deteriorates or odor appears, after 8,000 liters or at least every 3 months.
Downtime maintenance
If unused for over 2 weeks, disinfect before resuming use (procedure in the user manual).
