{"product_id":"unicel-c-9481","title":"Unicel C-9481 Replacement Filter for Jacuzzi Sherlock 120 | 120 Sq. Ft.","description":"\u003cdiv class=\"pz-pdp\"\u003e\n\u003ch3\u003eOverview\u003c\/h3\u003e\n\u003cp\u003eThe Unicel C-9481 is a pleated polyester cartridge filter element engineered for medium-to-large residential and light commercial pool installations, delivering 120 sq ft of filtration area via a high-pleat-count Reemay nonwoven polyester media pack. The element is configured with ABS injection-molded end caps — closed bottom with center locator boss, open top with handle-style grip — supported on a structural PVC core for axial rigidity under sustained operating pressure. Nominal filtration efficiency is rated in the 20-micron range under standard test conditions, with continuous service temperature rated to 104°F and operating pressures to 50 PSI. The 120 sq ft media area is sized to match the flow demand of the Jacuzzi Sherlock 120 housing across its full pump head curve, supporting extended service intervals between cleanings.\u003c\/p\u003e\n\u003cp\u003eService interval recommendation: rinse every 4–6 weeks under standard residential bather load, or at ΔP ≥ 8 PSI above clean-filter operating baseline, whichever occurs first. Chemical soak using TSP solution or commercial enzyme-based cartridge cleaner is recommended every 3–6 months to remove oils, lotions, and organic film resistant to rinse-only service. Replace annually or upon visual inspection failure (pleat channeling, fabric tears, end cap delamination, or crushed core). Chemical compatibility: continuous operation at ≤ 10 ppm free available chlorine; muriatic acid wash at 1:20 dilution compatible with ABS end cap construction for calcium scale removal (20-minute maximum exposure, rinse thoroughly before reinstallation); enzyme cleaners compatible without restriction. Post-installation, verify clean-filter operating pressure and log baseline ΔP for future service reference. 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.
