JBL AquaCristal UV-C: What do you mean by flow rate, and should I reduce the filter output?
Flow rate refers to the actual rate of flow through the UV-C water clarifier. If the UV-C water clarifier is connected behind the filter, all of the water cleaned by the filter flows through the clarifier and the sterilising effect lasts much longer (relative to the total amount of water in the tank). When using a filter with a high output, we recommended you either use separate installation by means of a small circulation pump or operation in a bypass, i.e. from the filter outlet into a Y piece (separation of the water), next, to install the clarifier in one of the circuits and then to connect the two hoses again by using a second Y piece, and then to lead them back into the tank.
