Annual renewal CSC city water - 20".

Triple filtration renewal mains water CSC 20- (set of 3 filters)

Pre-filter: 80-micron sediment sieve Washable and reusable 12 to 24 months

N°1 - Anti-scale & anti-corrosion (Refill CSC20-1) :

1 x REFILL food-grade silico-polyphosphate (more economical). Prevents limescale build-up in pipes/balloons and protects household appliances. Renewal 12-24 months * depending on hardness (limit 35 °F ). Water heatable up to 80 °C beyond which the polyphosphate loses its effectiveness (idem if the crystal level falls below 2/3 ).

N°2 - High impurity retention (Ref CSC20-2) :

1 x coiled filter sediment 50 µm (sand, sludge...). 100% polypropylene FDA, multi-layer multi-layer gradient structure for high capacity and longevity. NSF/ANSI 42 .useful length 20" / 250 mm

N°3 - PFAS chlorine & pesticide reduction (Ref CSC20-3) :

1 x carbon filter refines taste, filters chlorine impurities, pesticides , VOCS . Vegetable activated carbon block + polypropylene mesh . NSF/ANSI 42 .useful length 20" / 250 mm

MAINTENANCE :

• Cartridge N°1 refill of crystals : 24 months max. *.
• Cartridges N°2 (Sediment) and N°3 (Coal) : 12 months *.

Use only wrench for loosening. * depending on quality and volume of water filtered.

RENEWAL AID

• Equipment: dismantling wrench, flathead screwdriver, absorbent paper, basin.
• Close the by-pass (isolation) and run water directly.
• Unscrew the filter holders using the key .
• Remove filters; replace gaskets if necessary (lot 3 O-rings CSC).
• Reload glass holder N°1: empty, rinse foam, replace bottom foam + refill. refill + top foam, close.
• Wash bowls; if seals OK, edible grease then new filters.
• Open by-pass, purge air (bleed screw slightly open), close.
• Close direct flow valves and check tightness (paper).
  Please refer to the installation and commissioning instructions .
