It is a \u003cstrong\u003eUL listed refrigerant accumulator\u003c\/strong\u003e rated for use with \u003cstrong\u003eCFC, HCFC and HFC refrigerants\u003c\/strong\u003e, with \u003cstrong\u003e3\/4\" ODF solder connections\u003c\/strong\u003e on a roughly \u003cstrong\u003e3\" diameter by 12\" tall\u003c\/strong\u003e blue epoxy-coated steel shell and a \u003cstrong\u003e450 PSIG maximum working pressure\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eAn accumulator is the compressor’s insurance policy against \u003cstrong\u003eliquid slugging\u003c\/strong\u003e. During startup, defrost, load swings and expansion-valve hunting, liquid refrigerant can run down the suction line. The accumulator catches it in the shell and lets only vapor, carrying oil with it, pass back to the compressor. An internal \u003cstrong\u003einlet deflector\u003c\/strong\u003e keeps the incoming flow from splashing and helps collect the oil. The two copper stubs are marked: the line from the evaporator goes to the fitting labeled \u003cstrong\u003eINLET\u003c\/strong\u003e, and the factory \u003cstrong\u003erubber plugs\u003c\/strong\u003e should stay in until you are ready to braze so moisture stays out of the shell.\u003c\/p\u003e\n\n\u003cp\u003eInstall it in the suction line \u003cstrong\u003eas close to the compressor as possible\u003c\/strong\u003e, always \u003cstrong\u003eupright in the vertical position\u003c\/strong\u003e. On a heat pump or reverse-cycle system it belongs \u003cstrong\u003ebetween the reversing valve and the compressor\u003c\/strong\u003e. Purge with nitrogen while brazing, keep the flame away from the painted shell, and pull a deep vacuum before recharging. If a compressor has already failed from floodback, replace a contaminated accumulator along with it, because trapped liquid and oil can carry acid and debris back into the new compressor.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompressor Protection:\u003c\/strong\u003e Stops liquid floodback from reaching the compressor, the failure mode behind most \u003cstrong\u003eslugged valve plates, broken rods and washed-out bearings\u003c\/strong\u003e.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWide Refrigerant Range:\u003c\/strong\u003e Marked for \u003cstrong\u003eCFC, HCFC and HFC\u003c\/strong\u003e systems, so one accumulator style covers legacy and current refrigerant systems.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSized for 3\/4\" Suction Lines:\u003c\/strong\u003e The \u003cstrong\u003e3\/4\" ODF\u003c\/strong\u003e connections solder directly into a standard 3\/4\" copper suction line.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGenuine Copeland Part:\u003c\/strong\u003e A \u003cstrong\u003eCopeland A-AS series\u003c\/strong\u003e accumulator with the original \u003cstrong\u003eUL listed\u003c\/strong\u003e label, built to the manufacturer’s pressure rating.\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\u003eWhat size connections does it have?\u003c\/strong\u003e \u003cstrong\u003e3\/4\" ODF\u003c\/strong\u003e solder connections on a shell about \u003cstrong\u003e3\" in diameter and 12\" tall\u003c\/strong\u003e.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWhere does it go in the system?\u003c\/strong\u003e In the suction line close to the compressor, mounted upright, with the incoming line on the \u003cstrong\u003eINLET\u003c\/strong\u003e fitting.
