Membrane system in
reverse osmosis units:
Initial use: The RO 600 reverse osmosis unit comes complete with all parts required for operation.
1. Connect the RO 600 osmosis unit to the connection hose
ensuring the gasket
is seated correctly. Cut the included pressure-resistant hose

2. Route the discharge concentrate
into the drain or collect for cleaning or as service water.

4. Now slowly open the tap and carefully check that all screw connections and hose connections are tight.
5. Let the unit run for approx. 15 - 20 minutes during initial operation WITHOUT collecting the permeate (service water).
This removes any disinfectants in the membrane. Also keep this in mind when replacing the membrane.
Note: When the system is put into operation for the first time, it is recommended that the filter cartridge be removed from the ultrapure
water filter
to prevent premature exhaustion of the exchanger (Duresin RI ultrapure water resin). The PWT

When the round button is pressed, the measured value is displayed in ppm and in the best case will run with 000 ppm.
Notes:
∙ The supply water for the reverse osmosis unit should always come from a cold water line.
The operating temperature should be between 4° C and a temporary maximum of 30° C.
∙ The required operating pressure should be between 3 bar and a max. permissible operating pressure of 6 bar.
∙ Do not kink hoses. Do not use a stopcock or magnetic valve to cut off the permeate
∙ To shut down the unit, shut off the water tap for the cold water line or do so automatically by using a magnetic valve.
When using a magnetic valve, it must always be installed between the tap and the reverse osmosis unit.
Magnetic valves should be designed for an operating pressure of 0 - 12 bar.
∙ After restarting a shut-off unit, run the reverse osmosis unit unused for 15 minutes before the permeate can be used.
∙ The flow limiter with built-in flush valve
determines the ratio between concentrate and permeate. However, this is highly dependent on
10
the quality,
temperature and pressure of the supply water. The ratio is approximately 1 : 1.
∙ The RO 600 is not suitable for well water, rainwater, or similar.
Water with a high iron content will destroy the membrane and void the warranty.
∙ Do not use the unit whilst the domestic water system is being worked on. Dislodged deposits can clog the unit.
∙ Never allow the membrane
to dry out completely.

of the water supply. We recommend replacing the sediment filter
if water is high in sediment or chlorine. The flow capacity of the filters is approximately 7,500 litres.
∙ We recommend replacing the diaphragm
at least every 24 months.

Flushing the RO 600:
Depending on the quality of the tap water, dissolved substances can deposit on the membrane
rinsing the reverse osmosis unit, these deposited substances are removed. The RO 600 reverse osmosis unit is equipped with a preset flow
limiter with built-in flush valve
for this. To increase the life of the membrane

producing osmosis water, or at least every 4 – 6 weeks. Simply open the flush valve after generating reverse osmosis water for 5 – 15 minutes,
then close. This completes the flushing process. Note: If the RO 600 has not been used for a while, we recommend flushing the unit for at least
15 minutes before using it.

Replacing the 5 µm sediment filter
1. Shut off the tap for the cold water supply.
2. Open the filter housing with the provided housing key
3. Then replace the two filters and retighten the filter housings with the housing key
4. When reassembling, make sure that the two filters are in the correct position and that the seals are correctly seated.
5. Slowly open the tap and check the unit for leaks.
Replacing the membrane
1. Shut off the tap for the cold water supply.
2. Disconnect the hose connection for the membrane housing cover
3. Unscrew the membrane housing
Insert the membrane in the membrane housing, seals first (see drawing). Please be sure the membrane
with gaskets is tight in the membrane housing
4. Close the membrane housing. Be sure the gaskets are seated correctly.
5. Reconnect the hose to the membrane housing. Always insert the hose all the way into the

high-performance ion exchanger Duresin RI also binds residual amounts of nitrate, pollutants and salts contained in the permeate (pure water
from the osmosis unit) of an osmosis unit. A colour indicator contained in the cation exchanger shows when the resin is exhausted and needs
to be replaced. Duresin RI is a ready-to-use mixed bed resin which is also suitable for complete demineralisation and consists of equal parts of
a cation and an anion exchanger. Duresin RI enables an electrical conductivity of < 001 ppm (< 1 μS / cm conductivity) in all common mixed
bed applications. The colour indicator shows by a colour change from blue to green when the Duresin RI ultrapure water resin is exhausted.
Exhaustion of the ultrapure water resin can also be read off the digital pure water tester. Ideally, the permeate will drain off at 000 ppm. If the
value rises to > 10 ppm, the ultrapure water resin should be replaced.
1. Shut off the tap for the cold water supply.
2. Open the filter housing with the provided housing key
ultrapure water resin Duresin RI is replaced. After refilling the filter cartridge, close the filter housing with the housing key again.
3. Slowly open the tap and check the unit for leaks.

4. The system can be put into operation immediately.

5. The pure water tester should indicate 0 ppm.
PWT (pure water tester): The PWT is a TDS meter which can be used for the qualitative analysis of the process water (permeate) of reverse
osmosis units or for determining the water quality of pure water filters / mixed bed resins. When you press the power button, the scrolling value
will be displayed in ppm for 3 minutes. An increasing value in the process water indicates the need to change the membrane or filter and to
replace the pure water filter.

Calibration: Quickly double pressing the power button takes you into calibration mode. The ppm display flashes in calibration mode. By using
a calibration solution, the PWT can be easily adjusted to the specified value of the calibration solution with the help of the + / - buttons on the
back (calibration buttons). Press the power button again to save the chosen value.
Changing the batteries: To change the battery, simply pull out the battery holder on the side and change the battery. When inserting the
new battery, make sure that the + / - poles are aligned correctly.
