{"product_id":"unicel-fg-1002","title":"Unicel FG-1002 Replacement Filter for Hayward DEX2420MAN","description":"\u003cdiv class=\"pz-pdp\"\u003e\n\u003ch3\u003eOverview\u003c\/h3\u003e\n\u003cp\u003eThe Unicel FG-1002 is a complete DE filter manifold assembly engineered as a direct-replacement service component for Hayward ProGrid and Micro Clear DE filter platforms, supplying the central collector hub that interfaces all individual DE grid sectors with the filter tank outlet. Construction is injection-molded ABS thermoplastic with integrated grid-locating ports, machined to OEM dimensional tolerance for leak-free sector seating without supplemental adapter hardware. The manifold is rated for the standard residential DE filter operating envelope: continuous service to 50 PSI working pressure and 104°F maximum water temperature. The component is corrosion-immune under standard pool water chemistry, dimensionally stable through repeated backwash cycles, and machined to maintain bypass-free grid seal at all sector locations.\u003c\/p\u003e\n\u003cp\u003eService interval recommendation: inspect manifold at every annual DE filter teardown coinciding with grid recharge and full-tank cleaning; replace at first indication of port elongation, hairline cracking at grid seats, or DE blowback into the return line (indicating compromised sector-to-manifold seal). Pressure-based service trigger: investigate manifold integrity when ΔP fails to reset to clean baseline following a complete backwash and DE recharge cycle. Installation: seat each grid sector fully into the manifold port with positive engagement; torque the standpipe assembly per Hayward service specification and verify clean-pressure baseline within 1 PSI of pre-service reading before returning the system to circulation. Chemical compatibility: ABS construction tolerates unlimited free chlorine exposure, muriatic acid wash at 1:20 dilution, and enzyme-based DE filter cleaners without restriction; avoid solvent-based cleaning agents that attack ABS resin. Standard Unicel 90-day manufacturing defect warranty applies through authorized distribution.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cp\u003eYour order includes the selected quantity of DE filter grid sets.
