Operation
The Aquasure Premier RO system operates by pushing tap water through a series of filters to remove impurities. The purified water is then stored in the pressurized tank, ready for dispensing through the dedicated faucet.
How the Filtration Works:
- Stage 1 (Sediment Filter AF-PR1): Removes larger particles like dirt, rust, and sand, protecting subsequent filters.
- Stage 2 (Carbon Filter AF-PR2): Filters out chlorine, VOCs, chemicals, and other contaminants that affect taste and odor.
- Stage 3 (RO Membrane AF-MEM75): The core of the system, this semi-permeable membrane removes up to 99.99% of dissolved solids, heavy metals, bacteria, viruses, and other microscopic impurities.
- Stage 4 (Post-Carbon Filter AF-PR4): Provides a final polish to the water, removing any residual tastes or odors, ensuring the purest and freshest water.

Fejlfinding
This section provides solutions to common issues you might encounter with your Aquasure Premier RO system. For problems not listed here, please contact customer support.
- No Water Flow or Very Slow Flow:
- Check if the water supply valve to the system is fully open.
- Ensure the tank ball valve is open.
- Verify that the leak protection system (Flowlok) has not been activated. Reset if necessary after checking for leaks.
- Inspect filters for clogging. Replace sediment and carbon filters if they are past their recommended lifespan or appear discolored.
- The RO membrane might be clogged. Replace if necessary (typically every 18-24 months).
- Kontroller for knæk i slangen.
- Water Has Bad Taste or Odor:
- This usually indicates exhausted carbon filters (Stage 2 og Stage 4). Replace them.
- Ensure the system was properly flushed after installation or filter replacement.
- If the system has been idle for an extended period, flush the tank completely.
- Leaking from Connections:
- Sluk for vandforsyningen med det samme.
- Check all quick-connect fittings to ensure tubing is fully inserted and secure.
- Inspect O-rings and seals for damage.
- Ensure filters are properly twisted and locked into place.
- Low Water Pressure from Faucet:
- Check the pressure in the storage tank. It may need to be recharged or replaced if it's not holding pressure.
- Filters may be clogged, restricting flow. Replace as needed.
- Ensure the tank ball valve is fully open.
