It belongs to Copeland's \u003cstrong\u003eZF*K4 scroll family for refrigeration\u003c\/strong\u003e, which Copeland describes as using \u003cstrong\u003eliquid injection for improved reliability at low temperature\u003c\/strong\u003e, with the smooth scroll motion that gives low sound and vibration. The nameplate on this compressor reads \u003cstrong\u003eEmerson Copeland Scroll Compressor\u003c\/strong\u003e, \u003cstrong\u003ePOE oil with a 47 oz factory charge\u003c\/strong\u003e, \u003cstrong\u003e208-230 V, 1 phase, 60 Hz\u003c\/strong\u003e, a \u003cstrong\u003erun capacitor rating of 60 uF at 370 V\u003c\/strong\u003e, \u003cstrong\u003e109 A locked rotor current\u003c\/strong\u003e and \u003cstrong\u003ethermal protection\u003c\/strong\u003e, and distributors list the compressor at \u003cstrong\u003e11,000 Btu\/hr\u003c\/strong\u003e capacity. It is supplied with the \u003cstrong\u003e505-0819-00\u003c\/strong\u003e DTC injection port cap, the \u003cstrong\u003e527-0116-00\u003c\/strong\u003e vibration absorber grommet kit and the \u003cstrong\u003e998-0021-00\u003c\/strong\u003e terminal flag kit.\u003c\/p\u003e\n\u003cp\u003eCopeland's low-temperature \u003cstrong\u003eZF scroll\u003c\/strong\u003e literature makes \u003cstrong\u003einjection cooling mandatory\u003c\/strong\u003e: for the smaller \u003cstrong\u003eZF K4E\u003c\/strong\u003e models, that means \u003cstrong\u003eliquid injection through a discharge temperature control (DTC) valve\u003c\/strong\u003e, backed by \u003cstrong\u003ehigh discharge temperature protection\u003c\/strong\u003e on every compressor. Copeland specifies a \u003cstrong\u003efilter drier\u003c\/strong\u003e in the liquid line ahead of the DTC valve, \u003cstrong\u003eliquid refrigerant present at the valve inlet before start-up\u003c\/strong\u003e, and \u003cstrong\u003ereplacing the DTC valve and the filter drier whenever the compressor is replaced\u003c\/strong\u003e. The ZF family is \u003cstrong\u003emulti-refrigerant approved\u003c\/strong\u003e, and Copeland's low-temperature ZF documentation covers \u003cstrong\u003eR-407A, R-407F, R-448A and R-449A\u003c\/strong\u003e, so confirm your refrigerant and operating envelope in Copeland's selection software before ordering. The same \u003cstrong\u003eZF11K4E\u003c\/strong\u003e compressor is also built in three-phase versions such as \u003cstrong\u003eZF11K4E-TF5-931\u003c\/strong\u003e and \u003cstrong\u003eZF11K4E-TFD-931\u003c\/strong\u003e, which have a different motor, and in other sizes within the single-phase series, including \u003cstrong\u003eZF08K4E-PFV-931\u003c\/strong\u003e, \u003cstrong\u003eZF09K4E-PFV-931\u003c\/strong\u003e, \u003cstrong\u003eZF13K4E-PFV-931\u003c\/strong\u003e and \u003cstrong\u003eZF15K4E-PFV-931\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eBefore condemning a scroll, confirm the \u003cstrong\u003esupply voltage\u003c\/strong\u003e, test the \u003cstrong\u003erun capacitor\u003c\/strong\u003e against the \u003cstrong\u003e60 uF, 370 V\u003c\/strong\u003e marking on the nameplate, and check \u003cstrong\u003emotor winding resistance\u003c\/strong\u003e and \u003cstrong\u003einsulation to ground\u003c\/strong\u003e.

If the old compressor burned out, test the oil for acid, flush as needed and install a \u003cstrong\u003enew filter drier\u003c\/strong\u003e. Braze the \u003cstrong\u003esuction and discharge stub connections\u003c\/strong\u003e with a \u003cstrong\u003enitrogen purge\u003c\/strong\u003e, mount the compressor on the supplied \u003cstrong\u003egrommets\u003c\/strong\u003e, \u003cstrong\u003eevacuate\u003c\/strong\u003e thoroughly, and charge by the system's specification. \u003cstrong\u003ePOE oil\u003c\/strong\u003e absorbs moisture quickly, so keep the system open to air only as long as necessary.
