The top-loading, sealed chamber keeps fumes contained while the external control valve lets us fine‑tune feed rate for steady residuals. It’s a clean, low‑touch way to keep pools clear through hot spells and busy swim weekends.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eIn‑line install on the return line for hands‑off, consistent tablet feed.\u003c\/li\u003e\n  \u003cli\u003eTop‑loading, sealed canister for safe, easy refills.\u003c\/li\u003e\n  \u003cli\u003eExternal control valve for precise chlorination adjustments.\u003c\/li\u003e\n  \u003cli\u003eAccepts slow‑dissolving 3\" trichlor or 1\" trichlor\/bromine tablets.\u003c\/li\u003e\n  \u003cli\u003e2\" slip ports with bushings for 1½\" PVC—easy tie‑in on most pads.\u003c\/li\u003e\n  \u003cli\u003eNSF listed when used with Rainbow flow‑indicating device (R172276).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eR171096\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eIn‑line automatic chlorine\/bromine feeder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTablet Capacity\u003c\/td\u003e\n\u003ctd\u003e11 × 3\" tablets or 98 × 1\" tablets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTreats Pool Volume\u003c\/td\u003e\n\u003ctd\u003e6,500–27,000 gal (24.6–102.2 kL) bottom feed; 18,000–70,000 gal (68.1–265.0 kL) top feed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePort Size\u003c\/td\u003e\n\u003ctd\u003e2\" slip (includes 2\" × 1½\" reducer bushings)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Operating Pressure\u003c\/td\u003e\n\u003ctd\u003e50 psi (345 kPa)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation Location\u003c\/td\u003e\n\u003ctd\u003eReturn line, downstream of filter\/heater\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e~21\" H × 7\" W × 12\" D (service clearance ~22¼\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e~4.5 lb (2.0 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eNSF listed (with Rainbow R172276 flow‑indicating device)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eImportant\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eUse only slow‑dissolving trichlor or bromine tablets.
