Questions and answers - FAQ

Solution: First check that the cold water connection is turned on and that the lever on the supply tank connection is open. Remember that it may take some time for the filtration system to produce enough water to build up the operating pressure to ensure optimum water pressure in the water supply tank. Check to see 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 (article no.: TD3). Since an excessively high air pressure could damage the water supply tank. Proceed with caution. 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 liters indicates the gross water volume. The net volume of water is approx. 6 liters. The remaining 2 liters 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 diaphragm may 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 shutdown 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 conductance shows a value of 1-50ppm, a defective afterfilter may be the cause of the bitter aftertaste. In this case contact us.
