Description
Overview
The Unicel C-6960 is a complete DE grid filter element assembly engineered for Hayward DEX4800DA Quad DE 60 housings, providing 15.0 sq ft of total filtration area across a four-grid sector configuration. Media construction: polyester fabric over powder-coated steel frame, with reinforced perimeter seams and a center manifold port machined to OEM dimensional spec. Standard DE loading: 6.0 lb diatomaceous earth at initial precoat (1.0 lb per 10 sq ft × 60 sq ft system rating when used in full grid-set replacement). Operating pressure range: 8–30 PSI with a clean differential baseline typically 10–14 PSI. The grid assembly is dimensionally matched to the Hayward Quad DE 60 collector manifold and tank seat geometry for confirmed bypass-free installation.
Service interval recommendation: backwash when ΔP rises 5–8 PSI above clean baseline; recharge DE media after each backwash cycle at the 1.0 lb / 10 sq ft loading ratio. Annual service: full disassembly, manifold inspection, and grid fabric inspection for tears > 1 inch, seam delamination, or frame corrosion — replace complete grid set when any sector exhibits these failure modes or DE blowback is observed at the return. Chemical compatibility: polyester fabric and powder-coated steel frame tolerate continuous service at ≤ 10 ppm free available chlorine; muriatic acid soak (1:20 dilution, 20 minutes maximum) is compatible for calcium scale removal, followed by thorough fresh-water rinse. Enzyme degreaser cleaners are compatible without restriction and recommended for oil/surfactant fouling prior to acid treatment. Standard Unicel 90-day manufacturing defect warranty applies through authorized distribution.
