Description AD Flow Valve The AD Flow valve works by regulating the flow through the pool cleaner to the pump. As the filter collects debris, the valve will automatically maintain the correct flow. The installation of the AD Flow valve will depend upon the type of skimmer box. It is either installed straight in from the top of the Vac plate or from the bottom of the Vac plate. See the 3 different cases below. 1st case: with Waterco Skimmer Box Screw in the AD Flow valve connector into the top of the Vac plate 2nd case: with Poolrite Skimmer Box Screw in the AD Flow valve connector into the bottom of the Vac plate. 3rd case: with any other types of Skimmer Boxes Simply insert the AD Flow valve directly into the universal weir cuff which will then fit into the top of the Vac plate. Note: The AD Flow valve has three settings: High (3), Medium (2) and Low (1). To deliver the maximum pool cleaning efficiency, the AD Flow valve comes preset at a factory setting of 2. You will need to adjust the AD Flow valve when and if a problem occurs.
