Open the filter tank and remove the existing inner and outer cartridges. Inspect the housing and manifold for debris or damage. Install the new cartridges with the outer cartridge around the inner cartridge as per tank assembly, close the lid and restore circulation. Monitor filter pressure and backwash\/clean when pressure rises approximately 8–10 psi above baseline.\u003c\/p\u003e\n\u003ch2\u003eMaintenance Tip\u003c\/h2\u003e\n\u003cp\u003eClean the cartridges periodically (every 4-6 weeks depending on usage and debris load). Replace the pack when permanent loading has reduced flow and cleaning no longer restores pressure or clarity. Using the full 400 sq ft pack helps extend time between service and maintains consistent water clarity.\u003c\/p\u003e\n\u003cp\u003eSKU: 170146\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":46797759316143,"sku":"170146","price":519.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6415\/2239\/files\/sta-rite-mod-media-replacement-cartridge-set-for-s7m400-170146-pool-filter-parts-3155077.jpg?v=1777066906","url":"https:\/\/freshized.com\/products\/staritemodmediareplacementcartridgesetfors7m400170146pen170146","provider":"Freshized","version":"1.0","type":"link"}
