FactolT-installed additional components tue refen_ed to asoptions in this manual; factou-supplied but field-installedadditional components are referred to as accessories.The chiller software pall 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, andmotor sttutel: All connections fiom pressure vessels have exter-nal threads to enable each component to be plessure tested witha thleaded pipe cap during factory assembly.Cooler- This vessel (also known as the evaporator) islocated underneath the compressol: The cooler is maintained atlower temperature/pressme so evaporating refrigerant canremove heat fiom 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 fi_)m therefrigerant.Motor-Compressor- This component mainttfins sys-tem temperature and pressure differences and moves theheat-carrying refrigerant from the cooler to the condenser19XRV -- High Efficiency HermeticCentrifugal Liquid Chiller withVariable Frequency DriveUnit-Mounted19XRV 52 51 473/Cooler Size10-12 (Frame 1 XR) 55-57 (Frame 5 XR)15-17 (Frame 1 XR) 5F (Frame 5 XR)20-22 (Frame 2 XR) 5G (Frame 5 XR)30-32 (Frame 3 XR) 5H (Frame 5 XR)35-37 (Frame 3 XR) 60-62 (Frame 6 XR)40-42 (Frame 4 XR) 65-67 (Frame 6 XR)45-47 (Frame 4 XR) 70-72 (Frame 7 XR)50-52 (Frame 5 XR)5A (Frame 5 XR)5B (Frame 5 XR)50 (Frame 5 XR)Condenser Size10-12 (F .... 1 XR /15-17 (Frame 120-22 (Frame 2 XR)30-32 (Frame 3 XR)35-37 (Frame 3 XR)40-42 (Frame 4 XR)45-47 (Frame 4 XR)50-52 (Frame 5 XR)55-57 (Frame 5 XR)60-62 (Frame 6 XR)65-67 (Frame 6 XR)70-72 (Frame 7 XR)Compressor Code(First Digit Indicates Compressor Frame Size) _*Second digit will be a letter (example 4G3)on units equipped with split ring diffuser.DGControl Panel -- The control panel is the user interfacefor controlling the chiller It regulates the chiller's capacity aslequiled 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 status of motor starter• 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 st_ut 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 l/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.64 -Special Order Indicator- -- StandardS -- Special OrderMotor Voltage CodeCode Volts-Phase-Hertz62 -- 380-3-6063 -- 416-3-6064 -- 460-3-6052 -- 400-3-50Motor Efficiency CodeH -- High EfficiencyS -- Standard EfficiencyMotor CodeBD CD DB LBBE CE DC LCBF CL DD LDBG CM DE LEBH ON DF LFBJ CP DG LGCQ DH LHOR DJDKMODELNUMBERNOMENCLATURE27 99 Q 59843Year of Manufacture Place of ManufactureSERIAL NUMBER BREAKDOWNFig. 1 -- 19XRV Identification
