The manufacturer informs: 

Impianto domestico per la produzione di acqua priva di sali minerali (conducibilità e TDS sono pari a zero quindi); grazie al post-filtro con resina a viraggio ottico sarà possibile avere a disposizione acqua totalmente pura e deionizzata.

The system consists of five successive stages:

• 5 mcr 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

• doppio stadio con cartuccia al carbone granulare e carbon block (carbone attivo pressato): eliminano dall’ acqua cloro, metalli pesanti, residui di farmaci o pesticidi e altre sostanze potenzialmente dannose per l’ acquario; si consiglia di sostituire anch’ esse ogni 6 mesi o 3000 litri di acqua prodotta 
  

• Vontron membrane: specially developed for use in domestic systems, ULP1812 series membranes are designed for the treatment of low salinity water such as that flowing in our waterworks.
  

Already working at relatively low pressures, ULP1812s are perfectly suited for use in domestic systems and, in particular, for the production of osmotic water for aquariums.

• post-filtro composto da una cartuccia trasparente al cui interno agisce una resina deionizzante anti nitrati, fosfati e silicati; la resina vira dal verde al blu man mano che esaurisce il suo effetto deionizzante.
  The transparent cartridge allows the resin saturation status to be constantly monitored.

 
Continuous TDS reader:  

 HM Digital DM1 is an online meter for total dissolved salts (TDS) in water entering and leaving the system; it ensures constant monitoring of water quality. 

Technical specifications:

•    Range di misurazione : 0 – 9990 ppm
•    Accuratezza: +/- 2%
•    Raccordi standard ¼”
•    Durata batteria: piu di 1000 ore di uso continuo
 

Flush Valve for membrane flushing: 

the system is equipped with a valve that allows regular maintenance of the membrane withfeeling to extend its average life.

Simply turn the valve knob to allow the waste water to flow back in. of vessel and flows out from where the permeate would normally flow out, so that the membrane undergoes the washing process that improves its operating conditions.

Included in the package are:

- spanners for the vessel (membrane container) and cups

- steel diverter for connection to the water mains with 1/2" female thread (tap connection)

- 5mt of white 3/4" hose

- instruction manual in Italian
