Before removing the top lid, it is suggested to backwash the filter to discharge the contaminated DE powder. To remove the W3DE6020 requires a minimum of 68-1/8' vertical clearance. It uses a manual air relief valve that eliminates air buildup in the tank rather than having it force back thru the system.Ī 1-1/2' drain is used for quick drainage, and a one-piece flange clamp rests securely around the tank, securely fastening each half tightly together. The Pro-Grid tank is made with glass-reinforced thermoplastic that enhances durability and product life. The set of grids consists of 7 full grids 30' in length and 1 partial grid 30' in length. The Hayward Pro-Grid W3DE6020 uses a set or grids coated in pool grade diatomaceous earth. That's the same size as a human red blood cell. The Hayward Pro-Grid is capable of filtering out particulate as small as 5 microns. Pool Filter provides the highest level of filtration. High capacity, rapid release manual air relief valve bleeds air with a quick quarter turn of the lever.2' full-flow internal piping and plumbing for less resistance to flow and maximum performance.filter allows for both commercial and large residential applications and years of non-corrosive, trouble-free performance Convenient valve and plumbing options allow for customized control.Inlet diffuser elbow distributes flow of unfiltered water evenly to all filter elements and provides even distribution of D.E.Integral lift handles and uniform low-profile base make removal of grid nest fast and simple.Uniform low-profile base make removal of grid nest fast and simple.High impact grid elements designed for up-flow filtration and top-down backwashing for maximum efficiency.Allows quick access to all internal components without disturbing piping or connections

Heavy-duty, tamper-proof one piece flange clamp securely fastens tank top and bottom.Self-Aligned tank top and bottom make access to servicing the grid elements fast and simple.Filter tanks made from durable reinforced thermoplastic to meet the demands of the toughest applications and environmental conditions, including in-floor cleaning systems.In-ground spas or in-ground pool/spa combinations.Compatible with valves: SP0740DE (Selecta-Flo 2' SKT), SP0710XR50 (Vari-Flo 1 1/2' NPT), SP0715XR50 (Vari-Flo 2' NPT - Optional), SP0410X502S (Slide Valve 2' SKT - Optional).
