Ft.","description":"\u003cdiv class=\"pz-pdp\"\u003e\n\u003ch3\u003eOverview\u003c\/h3\u003e\n\u003cp\u003eThe Unicel C-9475 is a pleated polyester cartridge filter element engineered for residential and light commercial pool applications, delivering 75 sq ft of effective filtration area through a Reemay nonwoven polyester media pack. Dimensional specifications: 8.5-inch OD, 3.0-inch ID, 14.25-inch length, with ABS injection-molded end caps configured open-top, closed-bottom and seated on a Schedule-40 PVC core for axial rigidity under residential operating pressures. Nominal filtration efficiency falls in the 15–20 micron range under standard test conditions. The element is rated for continuous service at temperatures up to 104°F and operating pressures to 25 PSI, with UV-stabilized end cap adhesive formulated to resist degradation under standard pool water chemistry.\u003c\/p\u003e\n\u003cp\u003eService interval recommendation: residential installations — pressure-differential-based replacement triggered at ΔP ≥ 8–10 PSI above clean-filter operating baseline, or on an annual calendar cycle, whichever occurs first. Intermediate maintenance: rinse every 4–6 weeks; chemical soak with TSP or enzyme cleaner every 3–6 months to remove oils and organic loading that resist water rinsing. Chemical compatibility: polyester fabric and ABS end caps tolerate continuous service at ≤ 10 ppm free available chlorine and are compatible with muriatic acid soak at 1:20 dilution (20-minute maximum exposure) for calcium scale removal; rinse thoroughly before reinstallation. Enzyme cleaner compatible without restriction. Standard Unicel 90-day manufacturer's 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 spa filter cartridges.
