5.2 Functional sequence
If the toggle switch is turned to the ‘On‘ position, the magnetic valve (1) opens and water flows
into the system. After a short delay, the pump (4) will start.
Now the water is pressed into the reverse osmosis membrane at a pressure of 10-15 bar. The
flow is divided into a permeate and a concentrate part. The permeate content flows through the
flow indicator (7), the temperature sensor (8), the conductivity sensor (9) and the pressure
switch (10) into the ring line. The unused permeate flows back into the RO Medical-Basic via the
connection (12).
To save water, the concentrate portion is divided up again, one portion is given into the drain via
the flow indicator (16), the other is fed back in front of the pump.

6.6 Initial installation
1. Connect and check the raw water connection (1),
permeate flow (2), permeate back flow (3) and waste
water (4)
2. Open the inlet valve manually. To do this, turn the white
magnet coil 45° counter clockwise.
Now water is running into the device.
3. Carefully open the screw for the pump venting until a
water outlet can be seen. Then close the screw again and
reset the solenoid.
4. Make sure that the wall-mounted taps at the start and end
of the ring are open.
5.
6.
Start the device using the toggle switch.
Check all connections for leaks.
7.
8.
Open the shut-off valve permeate to the drain.
Allow the device to discard permeate for at least 30
minutes.

7.2 System on / off without permeate tank
System on
To start the device, turn the toggle switch to the right (on
position).
The green lamp lights up.
The pump starts after a short delay
System off
Reset toggle switch (position 0)
The green lamp goes out.
Pump stops.
If the device is switched off using the toggle switch, the rinse intervals are
carried out as programmed. If no rinsing is to take place, the device must be
switched off completely at the main switch. However, this is only
recommended for decommissioning.
