Ft.","description":"\u003cdiv class=\"pz-pdp\"\u003e\n\u003ch3\u003eOverview\u003c\/h3\u003e\n\u003cp\u003eThe Unicel C-9478 is a high-capacity pleated polyester cartridge filter element providing 150 sq ft of effective filtration area, engineered for medium-to-large residential and light commercial pool installations. Dimensional specifications: 8.5-inch OD, 4.0-inch ID, 23.25-inch length, with ABS injection-molded end caps in an open-top, semi-open-bottom configuration seated on a structural PVC core for axial rigidity under sustained operating pressure. Filter media is Reemay nonwoven polyester with a nominal filtration rating of 20 microns under standard test conditions; pleat geometry is optimized for low clean-pressure differential and extended dirt-holding capacity. The element is rated for continuous service to 104°F and operating pressures to 35 PSI, with UV-stabilized adhesive bonding at the end cap-to-media interface for resistance to standard sanitizer chemistry.\u003c\/p\u003e\n\u003cp\u003eService interval recommendation: rinse with fresh water every 4–6 weeks or at a ΔP rise of 8–10 PSI above clean operating baseline, whichever occurs first; chemical soak with TSP or commercial enzyme cleaner every 3–6 months to address oil and surfactant loading that resists mechanical rinsing. Full replacement is recommended annually or upon visual indication of media degradation, including fabric tears, pleat channeling, end cap delamination, or core deformation. Chemical compatibility: polyester media and ABS end caps tolerate continuous service at ≤ 10 ppm free available chlorine and are compatible with muriatic acid wash at 1:20 dilution (20-minute maximum exposure) for calcium scale remediation; enzyme cleaners are compatible without restriction. Post-installation, verify clean-filter operating pressure and log baseline ΔP for subsequent service interval tracking. 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 replacement spa filter cartridges.
