1 safety WARNINGOnly qualified personnel should install and service the equipment. The installation, starting up, and servicingof heating, ventilating, and air-conditioning equipment can be hazardous and requires specific knowledge andtraining. Improperly installed, adjusted or altered equipment by an unqualified person could result in death orserious injury. When working on the equipment, observe all precautions in the literature and on the tags,stickers, and labels that are attached to the R Air-CooledHelical Rotary Liquid ChillersInstallation, Operation, and MaintenanceRTAC-SVX01M-ENJanuary 2015 2015 trane All rights reservedRTAC-SVX01M-ENIntroductionRead this manual thoroughly before operating or servicingthis , Cautions, and NoticesSafety advisories appear throughout this manual personal safety and the proper operation ofthis machine depend upon the strict observance of Environmental ConcernsScientific research has shown that certain man-madechemicals can affect the earth s naturally occurringstratospheric ozone layer when released to theatmosphere.

2 In particular, several of the identifiedchemicals that may affect the ozone layer are refrigerantsthat contain Chlorine, Fluorine and Carbon (CFCs) andthose containing Hydrogen, Chlorine, Fluorine andCarbon (HCFCs). Not all refrigerants containing thesecompounds have the same potential impact to advocates the responsible handling ofall refrigerants-including industry replacements for CFCssuch as HCFCs and Responsible RefrigerantPracticesTrane believes that responsible refrigerant practices areimportant to the environment, our customers, and the airconditioning industry. All technicians who handlerefrigerants must be certified. The Federal Clean Air Act(Section 608) sets forth the requirements for handling,reclaiming, recovering and recycling of certainrefrigerants and the equipment that is used in theseservice procedures.

3 In addition, some states ormunicipalities may have additional requirements thatmust also be adhered to for responsible management ofrefrigerants. Know the applicable laws and follow three types of advisories are defined as follows:WARNINGI ndicates a potentially hazardoussituation which, if not avoided, couldresult in death or serious a potentially hazardoussituation which, if not avoided, couldresult in minor or moderate injury. Itcould also be used to alert againstunsafe a situation that could result inequipment or property-damage Field Wiring and GroundingRequired!Failure to follow code could result in death or seriousinjury. All field wiring MUST be performed by qualifiedpersonnel. Improperly installed and grounded fieldwiring poses FIRE and ELECTROCUTION hazards.

4 Toavoid these hazards, you MUST follow requirements forfield wiring installation and grounding as described inNEC and your local/state electrical Protective Equipment (PPE)Required!Installing/servicing this unit could result in exposure toelectrical, mechanical and chemical hazards. Before installing/servicing this unit, techniciansMUST put on all PPE required for the work beingundertaken (Examples; cut resistant gloves/sleeves,butyl gloves, safety glasses, hard hat/bump cap, fallprotection, electrical PPE and arc flash clothing).ALWAYS refer to appropriate Material safety DataSheets (MSDS)/ safety data Sheets (SDS) and OSHA guidelines for proper PPE. When working with or around hazardous chemicals,ALWAYS refer to the appropriate MSDS/SDS andOSHA/GHS (Global Harmonized System ofClassification and Labelling of Chemicals) guidelinesfor information on allowable personal exposurelevels, proper respiratory protection and handlinginstructions.

5 If there is a risk of energized electrical contact, arc, orflash, technicians MUST put on all PPE in accordancewith OSHA, NFPA 70E, or other country-specificrequirements for arc flash protection, PRIOR toservicing the unit. NEVER PERFORM ANYSWITCHING, DISCONNECTING, OR VOLTAGETESTING WITHOUT PROPER ELECTRICAL PPE ANDARC FLASH CLOTHING. ENSURE ELECTRICALMETERS AND EQUIPMENT ARE PROPERLY RATEDFOR INTENDED to follow instructions could result in death orserious Warranty InformationCompliance with the following is required to preserve thefactory warranty:All Unit InstallationsStartup MUST be performed byTrane, or an authorizedagent ofTrane, to VALIDATE this WARRANTY. Contractormust provide a two-week startup notification toTrane (oran agent ofTrane specifically authorized to performstartup).

A compressor nameplate islocated on each compressor.

9 When the unit arrives, if unitis not covered with a tarp, compare all nameplate data withordering, submittal, and shipping Unit NameplateSeeFigure 1, p. 6for a typical unit outdoorunit nameplate provides the following information: Unit model and size description. Unit serial number. Identifies unit electrical requirements. Lists correct operating charges of R- 134a andrefrigerant oil ( trane OIL00048). Lists unit test pressures. Identifies installation, operation and Maintenance andservice data literature (Pueblo). Lists drawing numbers for unit wiring diagrams(Pueblo).Model Number Coding SystemThe model numbers for the unit and the compressor arecomposed of numbers and letters that represent featuresof the equipment. Shown in the following table is a sampleof typical unit model number and the coding system position, or group of positions, in the model numberis used to represent a feature.

10 For example, in the firsttable, position 08 of the unit model number, Unit Voltage,contains the number 4 . A 4 in this position means that theunit voltage is 460/60 Model example of a typical unitmodel number (M/N) is:RTAC 350A UA0N NAFN N1NX 1 TEN NN0N N01 NModel number digits are selected and assigned inaccordance with the definitions as listed in Unit ModelNumber, p.
