ATTENTION:Warnings and Cautions appear at appropriate sections throughout this literature. Readthese carefully.WARNING: Indicates a potentially hazardous situation which, if not avoided,could result in death or serious injury.CAUTION: Indicates a potentially hazardous situation which, if not avoided,could result in minor or moderate injury. It may also be used to alert against unsafepractices.NOTICE: Indicates a potential situation which, if not avoided, may resultin equipment or property damage-only accidents, or possible environment pollution. It alsoprovides useful and helpful information that may benefit to a better unit operation or alonger usage life. But it doesn’t deem a best practice or a direct effect on benefit to unitoperation.ImportantEnvironmental Concerns!Scientific research has shown that certain man-made chemicals can affect theearth’s naturally occurring stratospheric ozone layer when released to theatmosphere. In particular, several of the identified chemicals that may affectthe ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon(CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon(HCFCs). Not all refrigerants containing these compounds have the samepotential impact to the environment. Trane advocates the responsiblehandling of all refrigerants—including industry replacements for CFCs suchas HCFCs and HFCs.Responsible Refrigerant Practices!Trane believes that responsible refrigerant practices are important to theenvironment, our customers, and the air conditioning industry. All technicianswho handle refrigerants must be certified. The Federal Clean Air Act (Section608) sets forth the requirements for handling, reclaiming, recovering andrecycling of certain refrigerants and the equipment that is used in theseservice procedures. In addition, some states or municipalities may haveRTWS.RLC-SVX15A-EN

additional requirements that must also be adhered to for responsiblemanagement of refrigerants. Know the applicable laws and follow them.WARNINGContains Refrigerant!System contains oil and refrigerant under high pressure. Recover refrigerantto relieve pressure before opening the system. See unit nameplate forrefrigerant type.Do not use non-approved refrigerants, refrigerant substitutes, or refrigerantadditives.Failure to follow proper procedures or the use of non-approved refrigerants,refrigerant substitutes, or refrigerant additives could result in death or seriousinjury or equipment damage.WARNINGPersonal Protective Equipment (PPE) Required!Always refer to appropriate MSDS and OSHA guidelines when handlingfluorocarbon refrigerants. Use proper breathing, eye, and body protectionduring the handling of fluorocarbon refrigerants. Failure to follow properhandling guidelines could result in death or serious injury.WARNINGLive Electrical Components!During installation, testing, servicing and troubleshooting of this product, itmay be necessary to work with live electrical components. Have a qualifiedlicensed electrician or other individual who has been properly trained inhandling live electrical components perform these tasks. Failure to follow allelectrical safety precautions when exposed to live electrical componentscould result in death or serious injury.RTWS.RLC-SVX15A-EN

1 Model Number Description1.1 OverviewThis manual covers the installation, operation and maintenance of the RTWS units.1.2 NameplatesThe RTWS unit nameplates are applied to the exterior surface of the control panel door.A compressor nameplate is located on compressor.1.2.1 Unit NameplateThe unit nameplate (Figure1.1) provides the following information: Unit model and size descriptor. Unit serial number. Identifies unit electrical requirements. Lists correct operating charges of R-134a and refrigerant oil. Lists unit design pressures Identifies installation, operation and maintenance and service data literature. Lists drawing numbers for unit wiring diagrams.Figure1.1 Unit Nameplate1.2.2 Compressor Nameplate1RTWS.RLC-SVX15A-EN

Model Number DescriptionThe compressor nameplate provides the following information: Compressor model number. Compressor serial number. Compressor electrical characteristics. Utilization range. Recommended refrigerant.1.2.3 Pressure Vessel NameplatesThe pressure vessel nameplate is different for the evaporators, condensers and oilseparators (RTWS only). The evaporator/condenser nameplates are located on the leftportion of the shells. The insulation over the nameplates is intentionally left unglued, forease in viewing the nameplate. The oil separator nameplate is on shell of oil separatorshell also.Figure1.2 Location of Pressure Vessel Nameplates (front)CondenserNameplate2RTWS.RLC-SVX15A-EN

Model Number DescriptionFigure1.3 Location of Pressure Vessel Nameplates (back)Oil separatorNameplateEvaporator Nameplate1.2.4 Model Number Coding SystemThe model numbers for the unit and the compressors are comprised of numbers and letterwhich represent features of the equipment.Each position or group of positions, in the number is used to represent a feature. Forexample, Unit voltage contains the number “C”. From the chart, it can be seen that a “C” inthis position means that the unit voltage is 380/50/3.Figure1.4 RTWS Model Number3 Taicang, ChinaDigit 01, 02, 03, 04 – Chiller ModelRTWS Water Cooled Chiller Series R Digit 10, 11 – Design SequenceSimplexA0 First design **** First Design, etc. increment when parts areDigit 05, 06, 07 – Unit Nominal Tonnageaffected for service purposes065 65 Nominal Tons085 85 Nominal TonsDigits 12 – Unit Type105 105 Nominal Tons1 Standard Efficiency/Performance125 125 Nominal TonsDigit 13 – Agency ListingDigit 08 – Unit Voltage/Unit Hertz0 No Agency ListingC 380/50/3C Manufactured to GB StandardsE 400/50/3Digit 14 – Pressure Vessel CodeS Special1 ASME Pressure Vessel CodeDigit 09 – Manufacturing Plant3 Chinese Code Pressure Vessel3RTWS.RLC-SVX15A-EN
