The manufacturer informs:

A domestic system for producing water free of mineral salts (conductivity and TDS are therefore zero) and totally deionised; ideal for those who need ultra-pure water in their aquarium. 

The system consists of four successive stages:   

• 5 mcr transparent sediment cartridge: removes suspended particles and rust or particulate residue from the water; recommended replacement every 6 months or 3000 litres of produced water; the transparency of the container gives the user the possibility to constantly monitor the cartridge's state of wear and tear

• activated carbon cartridge: removes chlorine, heavy metals, drug or pesticide residues and other substances potentially harmful to the aquarium from the water; it is also recommended to replace it every 6 months or 3000 litres of produced water 
   
• Le membrane Pentair (made in U.S.A.) serie TLC 50/75/100 sono state progettate dall’ azienda americana, leader mondiale nel settore, per il trattamento dell’ acqua potabile domestica ed hanno una produzione di permeato, a seconda del modello, di 50, 75 o 100 GPD (pari a circa 180, 275, 360 L/g) con un tasso stabilizzato di reiezione salina pari al 98% in condizioni di test standard.
  
  

  
  

• the supplied post-filter kit consists of a transparent cartridge inside which a deionising resin acts against nitrates, phosphates and silicates; the resin turns from green to blue as it exhausts its deionising effect.
  The transparent cartridge allows the resin saturation status to be constantly monitored.

Flush Valve for membrane flushing: 

l’impianto è dotato di una valvola che consente di effettuare una regolare manutenzione della membrana confeeling to extend its average life.

E’ sufficiente ruotare la manopola della valvola per far sì che l’acqua di scarto rientri all’ interno del vessel e fuoriesca da dove, normalmente, fuoriesce il permeato; in tal modo la membrana viene sottoposta al processo di lavaggio che ne migliora le condizioni operative.

Included in the package are:

- tightening spanner for easier screwing of the container cap in which the membrane is placed

- water mains connector with 3/4" female thread (washing machine connection)

- 5mt of white 3/4" hose

- instruction manual in Italian
