The Reverse osmosis is a unique filtration processwhich filters out pollutants in the molecular/nanometre range. In reverse osmosis, the tap water is pressed through a fine-pored, semi-permeable membrane. This membrane consists of laser-perforated, ultra-fine pores that ensure that the water molecules are pressed through the membrane and thus retain dissolved foreign substances up to 98.2 %.

In regions with high lime content in the water (from 12°dH - German hardness) a special lime pre-filter to prevent the UO membrane from being damaged or clogged at an early stage. Of course, you can also find the limescale pre-filter in our shop under accessories.

The filter system removes all pollutants from the water that previously negatively affected the natural taste of hot and cold drinks. In future, your drinks will taste even more natural and intense under optimal conditions, as they are free of unwanted substances. Here you can read which 8 reasons there are for a water filter.

Under optimal conditions, i.e. sufficient water pressure (min. 3 bar), optimal installation site, etc., a system (e.g. our AS5000) produces between 150-190 litres of filtered water per day.

We recommend that you disinfect the filter system every 3-6 months. Read here more about our disinfectants

If the filter system has not been used for a longer period of time, e.g. after a long holiday, let the water supply tank run empty for hygienic reasons and rinse the filter system. Important: If the unit is not used for a longer period of time, the membranes and the filters must be kept moist so that they do not dry out. We also recommend disinfection to prevent the formation of germs and biofilms in the entire filter system. You can see exactly how this works in one of our instructional videos for water filters.

Remember to change the filter regularly. Replace your filters and drain and rinse the water supply tank. A water revitalisation filter, such as the Vital Filter or Freshness Filter, can additionally improve the taste of the water.

Problem solving

Solution: First check that the cold water connection is turned on and that the lever on the storage tank connection is open. Remember that it may take some time for the filter system to produce enough water to build up the operating pressure to ensure optimum water pressure in the water storage tank. Check if a hose is kinked. Kinks in the hoses should be avoided at all costs.
If water still does not come out, go through the installation instructions a second time, step by step, and make sure you have done everything correctly. If the problem persists, please contact us.

Solution: Open the cold water connection and the tank connection.
If necessary, also make sure that you have inserted the activated carbon filter (GAC) into the housing "2" with the white ring facing upwards.

Solution: If the tank pressure is below 0.5 bar, you can change it by increasing the air pressure at the water supply tank using an air pump. Important Check the air pressure beforehand using an air pressure gauge (item no.: TD3). If the air pressure is too high, it could damage the water storage tank. Be careful when doing this. To do this, loosen the blue cap and screw a car air pump onto the valve. After pumping a few times, check that the water pressure is sufficient by opening the tap or using an air pressure gauge.

Solution: The tank capacity of 8 litres indicates the gross amount of water. The net water volume is approx. 6 litres. The remaining 2 litres of volume are distributed over an air cushion. This regulates the air pressure.

Solution: The filter system is designed for a water line pressure of 3 to 6 bar. At a lower pressure, the amount of water filtered and the water quality will decrease. In countries outside Germany, the water pressure is often lower. In this case, you must install a booster pump.

Solution: If the water line pressure is too high, the system and the membrane can be damaged. In this case, you should install a pressure reducer.

Solution: Check the pressure in the tank to make sure it is not too low. The optimum pressure should be 0.5-0.9 bar when empty. Increase the pressure as described in point 3.

Solution: This happens very rarely and is a sign that the automatic switch-off may be defective. Please contact us in this case.

Solution: Remove the water hose from the upper corner piece of the membrane housing. Now follow the hose to the automatic switch-off and turn it off at the automatic switch-off. Now fill a glass with this water. Taste the water and measure the conductivity with a TDS tester. If the water tastes good and the conductivity value is between 1-50ppm, a defective afterfilter may be the cause of the bitter aftertaste. In this case, contact us.

Solution: This is normal. The activated carbon filter must be soaked. The filter system must be rinsed. Rinse the system one more time.
