The sleeve surrounds the UV lamp inside the stainless steel chamber, keeping the lamp dry while its 254 nm UV output passes into the water. Every 140-series chamber holds two lamps, so each system uses two RQ-843 sleeves.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWhen to clean or replace the sleeve\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eLuminor's RAINIER manual calls for cleaning the quartz sleeve at least once a year, and more often when water hardness is near 7 grains per gallon or iron and manganese are present, because scale and mineral deposits block UV light. Clean both sleeves whenever you change the RL-843A lamps, and replace the sleeves every 24 months, or sooner if cracked, etched or still cloudy after cleaning.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWhy a genuine Luminor sleeve matters\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eRAINIER flow ratings, such as 180 GPM at 30 mJ\/cm² and 95% UV transmittance for the 140 series, are based on Luminor's matched lamp, sleeve and chamber.
