It has a \u003cstrong\u003ebrass body\u003c\/strong\u003e with \u003cstrong\u003ecopper sweat (solder) connection stubs\u003c\/strong\u003e on both ends, a \u003cstrong\u003eglass viewing port\u003c\/strong\u003e, and a \u003cstrong\u003ecolor-coded reference ring marked DRY, CAUTION and WET\u003c\/strong\u003e around a central \u003cstrong\u003emoisture-sensing element\u003c\/strong\u003e. One look tells you two things: whether the \u003cstrong\u003eliquid line\u003c\/strong\u003e is running full of \u003cstrong\u003eclear liquid refrigerant\u003c\/strong\u003e or showing \u003cstrong\u003ebubbles and flash gas\u003c\/strong\u003e, and whether the \u003cstrong\u003emoisture content\u003c\/strong\u003e of the system is acceptable.\u003c\/p\u003e\n\n\u003cp\u003eMoisture is one of the most damaging contaminants in a refrigeration system. It reacts with refrigerant and oil to form \u003cstrong\u003eacids\u003c\/strong\u003e, corrodes copper and steel, causes \u003cstrong\u003ecopper plating\u003c\/strong\u003e on bearing surfaces and valves, forms \u003cstrong\u003esludge\u003c\/strong\u003e, and can \u003cstrong\u003efreeze at the metering device\u003c\/strong\u003e. The element in the sight glass changes color with moisture level; compare it to the \u003cstrong\u003eDRY \/ CAUTION \/ WET\u003c\/strong\u003e ring with the system running and stable. A reading of \u003cstrong\u003eCAUTION\u003c\/strong\u003e or \u003cstrong\u003eWET\u003c\/strong\u003e means the \u003cstrong\u003efilter drier\u003c\/strong\u003e is saturated and should be replaced, then recheck the indicator after the system has run for several hours. Constant \u003cstrong\u003ebubbles\u003c\/strong\u003e after the drier point to \u003cstrong\u003elow charge\u003c\/strong\u003e or a \u003cstrong\u003erestriction\u003c\/strong\u003e. Install it in the \u003cstrong\u003eliquid line\u003c\/strong\u003e ahead of the metering device after the drier. Recover the refrigerant, \u003cstrong\u003ebraze with a nitrogen purge\u003c\/strong\u003e, protect the glass and element from heat, then pull a \u003cstrong\u003edeep vacuum\u003c\/strong\u003e before recharging. Match the \u003cstrong\u003esweat connection size\u003c\/strong\u003e to the line size of your original indicator.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFlow and Moisture in One Look:\u003c\/strong\u003e Shows \u003cstrong\u003eliquid refrigerant flow\u003c\/strong\u003e and \u003cstrong\u003emoisture condition\u003c\/strong\u003e from a single \u003cstrong\u003esight glass\u003c\/strong\u003e.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eColor-Coded Ring:\u003c\/strong\u003e The \u003cstrong\u003eDRY, CAUTION and WET\u003c\/strong\u003e reference ring makes the reading unambiguous without a chart.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrass Body, Copper Stubs:\u003c\/strong\u003e \u003cstrong\u003eBrass construction\u003c\/strong\u003e with \u003cstrong\u003esweat connections\u003c\/strong\u003e brazes into copper liquid lines.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eProtects the Compressor:\u003c\/strong\u003e Early warning of moisture lets you change the \u003cstrong\u003efilter drier\u003c\/strong\u003e before \u003cstrong\u003eacid\u003c\/strong\u003e and \u003cstrong\u003esludge\u003c\/strong\u003e damage the compressor.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHow do I read it?\u003c\/strong\u003e Run the system until it is stable, then compare the \u003cstrong\u003eelement color\u003c\/strong\u003e to the \u003cstrong\u003eDRY \/ CAUTION \/ WET\u003c\/strong\u003e ring on the glass.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWhere is it installed?\u003c\/strong\u003e In the \u003cstrong\u003eliquid line\u003c\/strong\u003e, after the \u003cstrong\u003efilter drier\u003c\/strong\u003e and ahead of the \u003cstrong\u003emetering device\u003c\/strong\u003e.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWhat if it shows WET or CAUTION?\u003c\/strong\u003e Replace the \u003cstrong\u003efilter drier\u003c\/strong\u003e (and the \u003cstrong\u003ecore\u003c\/strong\u003e if it is a replaceable-core type), then run the system and recheck.
