Installation,Operation, and Maintenance - Trane

1 SAFETYWARNINGOnly qualified personnel should install and service the installation, starting up, and servicing of heating, ventilating, and air-conditioning equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipmentby an unqualified person could result in death or serious working on the equipment, observe all precautions in the literature andon the tags, stickers, and labels that are attached to the ,Operation,and MaintenanceVAV-SVX01D-ENMarch 2014 2014 Trane All rights reservedVAV-SVX01D-ENIntroductionRead this manual thoroughly before operating or servicingthis , Cautions.

2 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. 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 Refrigerant PracticesTrane believes that responsible refrigerant practices areimportant to the environment, our customers, and the airconditioning industry.

3 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. 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.

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.

5 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.

6 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.
