Reverse osmosis system - processing essentially consists in an adjustable reduction of
xed residue in treated water.
The machine is intended for use in a closed and protected environment, not outdoors.
Its use consists of treating and supplying drinking water for human consumption and
for technical use. Any other use is not permitted.
Attention: This equipment requires regular maintenance to guarantee the
potability requirements of the treated drinking water and to maintain the im-
provements declared by the manufacturer of the reverse osmosis system for
household use, to treat drinking water. Equipment for the treatment of drinking
water. Input water must be drinkable according to Ministerial Decree no. 31
of 2 February 2001.

For the maintenance method, see the specic chapter.
Specic tests were carried out to dene the time of use and the maintenance methods.
Furthermore, a water sample was analysed to verify for altered parameters and for
compliance with Ministerial Decree no. 31 of 2 February 2001.
Important: After installation, the machine must be powered on for hygiene
reasons (ushing) and for a correct management of the exhausted lter.
Sanitise and replace the pre-lter after periods of disuse longer than 10 days

Please nd below the potability test results for water samples taken before and after DP. Both
tests, carried out by an accredited institute, conrm the water as drinkable. In particular, it is
conrmed that treatment efficiently reduces various parameters, in particular conductivity,
hardness and various chemical substances.
