Set-Up
To fix the unit to a wall, disconnect the two wall brackets from the module and fix them directly on
the wall or a mounting plate - preferably near a tap connection. Press module into the brackets -
ready.
Then, mount the membrane and connect the tubes. To avoid any failures, follow the instructions
carefully:
Tube fittings:
Put the nut and small ring on the tube.
Push the tube tight into the fitting and fix the nut.
The connections of the unit are (please refer to Fig. 1):
Note: Before taking the unit into first operation, rinse the pre-filter and then attach it to
the reverse osmosis module!
1. Attach the tap connection to a 3/4" tap. If necessary, use a reduction piece (not included in
shipment).
2. By using a piece of hose, one puts it from the tap connection into the tap water inlet of the unit
into the pre-filter (1).
3. Connection between pre-filter and reverse osmosis module.
4. Waste water outlet (6) at the flush valve.
5. Pure water (permeat) (5).

Mounting the membrane:
Remove the screw cap of the module housing (Fig. 1, No. 7). Take
the membrane out of the plastic bag and put it into the reverse
osmosis module. Take care to insert the membrane in the right
direction (Fig. 2, No. 2) with both sealings (Fig. 2, No. 1) directed
to water outlet. The membrane has to be pushed forward until the
2 sealings are in the right position at the top and the pure water
seal (Fig. 2, No. 3) is fixed. Before the housing can be closed,
mount the O-ring (Fig. 1, No. 9) on the reverse osmosis module.
3. Starting
When all connections are tight, you can open the tap water. The
minimum water pressure for the unit is 3 bar. The nominal capacity
is reached at 4 bar. If the pressure drops below 3 bar, the
production capacity is reduced, below 2 bar it reduces also the
reduction rates.
Firstly, check all connections on water tightness. If leakage occurs,
tighten the fittings or the housing. Now, the concentrate flows out
of the outlet at closed flush valve. After some minutes, also purified
water flows out of the permeat outlet, however, at a lower flow
rate.
