It could also be used to alert against unsafe practices.NOTICE: Indicates a situation that could result in equipment or property-damage onlyaccidents.ImportantEnvironmental Concerns!Scientific research has shown that certain man-made chemicals can affect the earth's naturallyoccurring stratospheric ozone layer when released to the atmosphere. In particular, several of theidentified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorineand Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not allrefrigerants containing these compounds have the same potential impact to the environment.Trane advocates the responsible handling of all refrigerants-including industry replacements forCFCs such as HCFCs and HFCs.Responsible Refrigerant Practices!Trane believes that responsible refrigerant practices are important to the environment, ourcustomers, and the air conditioning industry. All technicians who handle refrigerants must becertified. The Federal Clean Air Act (Section 608) sets forth the requirements for handling,reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in theseservice procedures. In addition, some states or municipalities may have additional requirementsthat must also be adhered to for responsible management of refrigerants. Know the applicablelaws and follow them. WARNINGR-410A Refrigerant under Higher Pressure than R-22!The unit described in this manual uses R-410A refrigerant which operates at higher pressuresthan R-22 refrigerant. Use ONLY R-410A rated service equipment or components with this unit.For specific handling concerns with R-410A, please contact your local Trane representative.Failure to use R-410A rated service equipment or components could result in equipment orcomponents exploding under R-410A high pressures which could result in death, serious injury,or equipment damage. 2009 Trane All rights reservedSSP-SVX14A-EN

Pre-InstallationClearancesProvide enough space around the unit to allow unrestricted access to all service points. Refer toFigure 3, p. 12 through Figure 5, p. 14 for unit dimensions and minimum required service and freeair clearances. Observe the following points to ensure proper unit operation.1. Do not install the unit under a low overhang. Outdoor discharge must not be restricted. SeeNotes in Figure 3, p. 12 through Figure 5, p. 14.Important:Do not obstruct outdoor discharge air. This can result in warm air recirculationthrough the coil.2. Do not locate the unit in a position where runoff water can fall into the fan discharge openings.3. Outdoor intake air is supplied from three or four sides of the unit. Adhere to the minimumrequired clearances given in Figure 3, p. 12 through Figure 5, p. 14.Unit Mounting WARNINGMounting Integrity!Ensure that the roof structure supports are strong enough to support the weight of the unit andany accessories. Failure to do so could result in death or serious injury or possible equipment orproperty-only damage.Rooftop MountingIf the unit will be roof mounted, determine forcertain that the structure is strong enough tosupport the unit and any required accessories.Unit weights are given in Table 1 and Table 2,p. 8. The unit should be elevated on a level, fieldfabricated four-inch steel or wood 4" x 4"mounting frame. Complete the frame and secureit into position before lifting the unit to the roof.The mounting frame must support a minimum ofthree of the unit’s four sides and should span roofsupports to distribute the load on the roof.Figure 1. Roof Mounted UnitOutdoor UnitGas (Suction)Line - InsulatedLiquid LineInsulatedUnit MountingChannels6”RadiusElevation(Mounting Frame)Ground Level MountingFor ground level installation, the unit base shouldbe adequately supported and hold the unit nearlevel.

Use ONLY R-410A rated service equipment or components with this unit.For specific handling concerns with R-410A, please contact your local Trane representative.18SSP-SVX14A-EN
InstallationFailure to use R-410A rated service equipment or components could result in equipment orcomponents exploding under R-410A high pressures which could result in death, serious injury,or equipment damage.Each TWA unit ships with a holding charge of dry nitrogen The nitrogen should be removed andthe entire system evacuated (at the proper time) to avoid possible contamination.1. Remove the compressor service access panel.2. Locate the liquid and suction line service valves. Check that the piping connection stubs on thevalves (Figure 8) line up properly with the holes in the unit cabinet.Figure 8. Outdoor Units - Refrigerant Piping (with dry nitrogen)3. Remove the refrigerant connection seal caps and open the service valve slowly to release thenitrogen from the unit.NOTICESystem Component Damage!Do not remove the seal caps from refrigerant connections, or open the service valves untilprepared to braze refrigerant lines to the connections. Excessive exposure to atmosphere ( 5min.) may allow moisture or dirt to contamin
