5Factory-installed additional components are referred to asoptions in this manual; factory-supplied but field-installedadditional components are referred to as accessories.The chiller software part number of the 19XRV unit islocated on the back of the ICVC.CHILLER FAMILIARIZATION(Fig. 1 and 2)Chiller Information Nameplate — The informationnameplate is located on the right side of the chiller controlpanel.System Components — The components include thecooler and condenser heat exchangers in separate vessels,compressor-motor, lubrication package, control panel, andVFD. All connections from pressure vessels have externalthreads to enable each component to be pressure tested with athreaded pipe cap during factory assembly.Cooler — This vessel (also known as the evaporator) islocated underneath the compressor. The cooler is maintained atlower temperature/pressure so evaporating refrigerant canremove heat from water flowing through its internal tubes.Condenser — The condenser operates at a highertemperature/pressure than the cooler and has water flowingthrough its internal tubes in order to remove heat from therefrigerant.Motor-Compressor — This component maintains sys-tem temperature and pressure differences and moves theheat-carrying refrigerant from the cooler to the condenser.Control Panel — The control panel is the user interfacefor controlling the chiller. It regulates the chiller’s capacity asrequired to maintain proper leaving chilled water temperature.The control panel:• registers cooler, condenser, and lubricating systempressures• shows chiller operating condition and alarm shutdownconditions• records the total chiller operating hours• sequences chiller start, stop, and recycle under micropro-cessor control• displays the status of the VFD• provides access to other CCN (Carrier ComfortNetwork®) devices and energy management systems• languages pre-installed at factory include: English,Chinese, Japanese, and Korean.• International Language Translator (ILT) is available forconversion of extended ASCII characters.Variable Frequency Drive (VFD) — The VFD al-lows for the proper start and disconnect of electrical energy forthe compressor-motor, oil pump, oil heater, and control panel.Storage Vessel (Optional) — There are 2 sizes ofstorage vessels available. The vessels have double relief valves,a magnetically-coupled dial-type refrigerant level gage, aone-inch FPT drain valve, and a 1/2-in. male flare vapor con-nection for the pumpout unit.NOTE: If a storage vessel is not used at the jobsite, factory-installed isolation valves on the chiller may be used to isolatethe chiller charge in either the cooler or condenser. An optionalpumpout system is used to transfer refrigerant from vessel tovessel.19XRV 52 51 473 DG H 64 –19XRV — High Efficiency HermeticCentrifugal Liquid Chiller withVariable Frequency DriveUnit-MountedCondenser Size20-22 (Frame 2 XRV)30-32 (Frame 3 XRV)35-37 (Frame 3 XRV)40-42 (Frame 4 XRV)45-47 (Frame 4 XRV)50-52 (Frame 5 XRV)55-57 (Frame 5 XRV)60-62 (Frame 6 XRV)65-67 (Frame 6 XRV)70-72 (Frame 7 XRV)75-77 (Frame 7 XRV)80-82 (Frame 8 XRV)85-87 (Frame 8 XRV)Special Order Indicator– — StandardS — Special OrderMotor Voltage CodeCode Volts-Phase-Hertz62 — 380-3-6063 — 416-3-6064 — 460-3-6052 — 400-3-50Compressor Code(First Digit Indicates Compressor Frame Size)*Motor Efficiency CodeH — High EfficiencyS — Standard Efficiency27 05 Q 71843Week of YearYear of ManufactureUnique NumberPlace of ManufactureMODEL NUMBER NOMENCLATURESERIAL NUMBER BREAKDOWNCooler Size20-22 (Frame 2 XRV)30-32 (Frame 3 XRV)35-37 (Frame 3 XRV)40-42 (Frame 4 XRV)45-47 (Frame 4 XRV)50-52 (Frame 5 XRV)5A (Frame 5 XRV)5B (Frame 5 XRV)5C (Frame 5 XRV)55-57 (Frame 5 XRV)5F (Frame 5 XRV)5G (Frame 5 XRV)5H (Frame 5 XRV)60-62 (Frame 6 XRV)65-67 (Frame 6 XRV)70-72 (Frame 7 XRV)75-77 (Frame 7 XRV)80-82 (Frame 8 XRV)85-87 (Frame 8 XRV)*Second digit will be a letter (example 4G3) on units equipped with split ring diffuser.Compressor Frame2 3 3 4 4 5BDBEBFBGBHBJCDCECLCMCNCPCQCRKBKCKDKEKFKGKHDBDCDDDEDFDGDHDJDKLBLCLDLELFLGLHEHEJEKELEMENEPEQMotor CodeFig. 1 — 19XRV Identificationa19-1684
