    pentair quad DE with Hi-Flow Valve 261050: correct installation

    I am about to replace my aging pool equipment with something more energy efficient: pentair intelliflo pump, as well as the filter (current FNS60) and will go with the quad DE 100 with the Hi-Flow Valve 261050. There is not clear documentation on how to install the filter with the valve out there. I know it should be install like a cartridge or sand filter. but I saw a few threads with wrong install and it was a very costly mistake.
    Could you please help with the right install steps (pictures, diagram...)?
    Thanks!
    Pool: 25,000 gal pool with 7x5 spa (8 jets)
    Pentair Equip: Intelliflo VS Pump (to be installed), MasterTemp 400 Heater, Quad DE 100 Filter

    There isn't many pictures from the manufacturer but the valve is pre plumbed to fit on filter. The manual for the valve will tell you where other ports go. The valve also is marked for the respective ports. In my experience the filter doesn't backwash very well and you almost have to treat it like a cartridge filter
