COMPONENTS
2.3.
1 Prefilter
The device is supplied with an external PROFINE M BLU carbon block cartridge to ensure chlorine removal
and filtration of raw water.
2.3.2 Pump with motor 150W
To increase operating water pressure, it is installed inside the machine a pump mini 200 l/h, leaded by an
asynchronous motor.
2.3.3
Membrane
The membranes are the core of the machine; four membranes Filmtec TW30 1812 100gpd are installed.

DESCRIPTION
There are three external hydraulic connections on the back of the device, respectively, for the inlet water
¾”G, the outlet water ¾”G to the dish/washmachine and the line used for drain off (6mm diameter).
On the rearside of the machine, there is also the power cord, and air vents.
It is necessary to install an external prefilter PROfine BLU carbon block medium to ensure chlorine
removal and filteration of raw water.
The water flows then through the quick connection carbon filter. The carbon block filter facilitates the
elimination of the unpleasant chlorine taste, without compromising the desirable mineral properties of
the water. These activated carbon filters can also absorb potential trace organic micro pollutants, various
chemicals
organic and inorganic (i.e. chlorine composites), chlorine residue used to disinfect water,
haloforms, pesticides, surface-active agents.
From the connection to the main plumbing network, the water arrives to the inlet solenoid valve, and
with a T fitting to the min pressure switch and then to the pump.
The min pressure switch prevents the pump to run dry. In chase of low pressure, alarm is acustic signalled
and then the machine makes automatic restart after one minute.
When consecutives low pressure alarm occures, the restart delay automatically increases.
Water is then pumped at high pressure by the brass vane pump connected to the liquid cooled motor. The
water arrives at high pressure to the vessels contain the reverse osmosis membranes. The water
permeates the layer flowing into the collection tubes, and then it is directed to the main tube of the
membrane, wrapped in various layers. The permeate yield comes from the main tube of the membrane
and is sent directly to the outlet.
For automatic start/stop of the machine, a check valve and a max pressure switch are installed in the
permeate line, before outlet connection.
On the bottom and on the right side of the machine, there are two leakage probes (for vertical and
horizontal operating); if leakage occurs the machine stops automatically and makes acustic alarm.
The drain must be connected to the drain siphon with the backflow preventer fitting in the package.
The drain capillary is used to set the drain flow and recovery ratio.
