RESSURE GAUGES
1/ the pressure gauge « Outlet filters » show the pressure of water supply after filtration. The
guideline value for correct operation is about 3.0 to 4.0 bars (43 to 58 PSI) when the water purifier is
working. If this value is greater than 5 bars (72 PSI), it is imperative to install a pressure reducer on
the water supply network.
2/ the pressure gauges « Exit pump » can check the correct working of pumps and also to the
integrity of reverse osmosis membranes. The guideline value for proper operation is about 4.5 - 8
bars (65 – 94 PSI), when the water purifier is working (LED "Power" and "Pump" switch on).
3/ the pressure gauges « exit tank » is used to check storage tank pressure. The max value possible is
about 3 to 3.5 bars (43.5 PSI) when the water purifier is standby (LED « Power » and « Full » switch
on).

ENERAL DESCRIPTION
The "O-Maxi" water purifier is a water treatment system that includes a series of prefiltration
cartridges for the network water: Sediment filter 5 μm + Block carbon Sediment filter 1 µm
Once this water is treated, it is then injected via a booster pump into 1 reverse osmosis membrane
which is a combination of bi-osmosis process.
The water obtained is thus discharged of 90% of its organic and inorganic compounds.
In order to complete the complete treatment, this water is then injected into an ion exchange resin
bottle and then filtered by a 1 μm post-treatment filter.
The electromechanical assembly is managed by an electronic control unit.
