{"product_id":"unicel-c-8416","title":"Unicel C-8416 Filter for Waterway 817-0150P (2006 \u0026 prior) | 150 Sq. Ft.","description":"\u003cdiv class=\"pz-pdp\"\u003e\n\u003ch3\u003eOverview\u003c\/h3\u003e\n\u003cp\u003eThe Unicel C-8416 is a high-capacity pleated polyester cartridge filter element engineered for large-format pool filtration systems, providing 150 sq ft of effective filtration area through a Reemay nonwoven polyester media pack on a reinforced core assembly. The element features ABS injection-molded end caps with a closed-bottom, open-top geometry sized for the Waterway 4-cartridge manifold platform, with dimensional tolerances held to OEM specifications for bypass-free seating in the filter canister. Nominal filtration efficiency is 20 microns under standard test conditions, with the element rated for continuous operating temperatures to 104°F and operating pressures to 50 PSI consistent with residential and light commercial duty cycles. The 150 sq ft area distributes circulation flow across a low face-velocity media bed, extending service cycles and reducing pump head loss relative to undersized configurations.\u003c\/p\u003e\n\u003cp\u003eService interval recommendation: rinse every 4–6 weeks of operational service or at ΔP ≥ 8 PSI above clean-filter operating baseline, whichever occurs first. Chemical soak with TSP or commercial enzyme cleaner is recommended at 3–6 month intervals to remove oils, surfactants, and organic loading that resist mechanical rinsing. Replace annually or upon visual identification of fabric tears, pleat channeling, or core deformation. Chemical compatibility: continuous service at ≤ 10 ppm free available chlorine; muriatic acid wash compatible at 1:20 dilution (20-minute maximum exposure) for calcium scale remediation; enzyme cleaners compatible without restriction. Post-installation, verify clean-filter operating pressure and log baseline ΔP for subsequent service-trigger reference. Standard Unicel 90-day manufacturer 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 replacement pool filter cartridges.
