1 SAFETYWARNINGOnly qualified personnel should install and service 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 working on the equipment, observe all precautions in the literature and on the tags,stickers, and labels that are attached to the Rooftop Air ConditionersPrecedent - Electric/Electric3to10 Tons 60 HzInstallation, Operation, and MaintenanceModel Numbers:TSC037E -TSC067 ETHC036E -THC072 ETSC036E -TSC060 ETHC120 FTSC072F -TSC120 FTHC037E -THC067 ETHC048F -THC102 FRT-SVX22P-ENApril 2015 2015 Trane All rights reservedRT-SVX22P-ENIntroductionReadthis manualthoroughlybeforeoperatingorservici ngthis , 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 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. In addition, some states ormunicipalities may have additional requirements thatmust also be adhered to for responsible management ofrefrigerants.

3 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 or property-damage FieldWiring 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 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).

4 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. 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, ORVOLTAGETESTINGWITHOUT PROPER ELECTRICAL PPE ANDARC FLASH CLOTHING.
