   Ideal for: Wells, old water networks, water with microbiological contamination or areas with insufficient chlorination. Traps asbestos fibers and offers maximum protection and safety.
5. F4-DOWN-Alkaline – Quadruple Filter with Alkalization (4 Stages)
   1st Stage (PPF): Polypropylene for trapping sediment up to 1μm.
   2nd Stage (CTO): Activated Carbon in solid form for final filtration of organic substances.
   3rd Stage (Alkaline): Alkalization filter with mineral granules that increase water pH (7.5-9.5), enriching it with ions of calcium, magnesium and potassium.
   4th Stage (GAC): Granular Activated Carbon for chlorine and odor removal.
   Ideal for: Those seeking alkaline water with improved health properties, better hydration and antioxidant action.

Important Water Pressure Information

⚠️ Caution: If you are on the 1st floor or lower (ground floor, basement), water pressure may be very high. A pressure reducer is highly recommended to avoid leaks and damage to the filtration system. Ideal operating pressure is 2-4 bar. Pressure above 6 bar may cause leaks.

Technical Specifications

Filter Replacement Frequency

Recommended filter replacement: Every 6 months, depending on water quality and usage. If you notice reduced pressure or change in water taste, replace earlier.

Installation Instructions

1. Installation location: Choose an accessible location under the counter, close to the water supply and with easy access for future filter replacement.
2. Faucet installation: Drill a hole in the counter (12mm) and install the chrome faucet. Secure it from below with the included nut.
3. Shut off water supply: Before starting, close the water supply valve under the counter.
4. Install filters: Insert the filters into the housings according to the indicated sequence (IN → OUT).
5. Connect to water supply: Use the included metal T-valve (Feed Adapter) to connect the system to the 1/2" water supply (cold water under the counter). The T-valve has 1/2" inlet and 1/4" outlet for the filter.
6. Connect tubing: Connect the 1/4" tubing (2 meters) from the T-valve outlet to the filter inlet (IN). Then, connect the filter outlet (OUT) to the faucet using the 1/4" tubing.
7. Flush system: Open the water supply and let water run from the faucet for 5-10 minutes to flush the filters of any activated carbon dust or residue.
