Installation Operation Maintenance

InstallationInstalling the unitDischarge ConversionIf a unit is to be converted toVertical discharge, a panel must beacquired from Trane.If a unit is to be converted toHorizontal discharge, the followingconversion must be performed:1. Remove the return and supplyduct covers.2. Apply gasket to the return ductcover.Figure 6 - Unit mounting on roof13. Position duct covers as shown inFigure 4. The supply duct cover isinstalled (insulation side down)over the downflow returnopening by engaging one side ofthe panel under a retaining angleand securing the other side with3 screws.4. Slide return duct cover(insulation side up) into supplyopenings until outer edge of theduct cover engages with the tworetaining clips on the ductflanges. Secure the outer edge ofthe each duct cover with twoscrews.Figure 5 - Conversion to horizontaldischarge1 = Supply duct cover, insulation sidedown2 = Return duct cover with gasketinstalled, insulation side up3 = Edge of duct cover goes underretaining angleUnit mounting on roofFix the rooftop curb on the jointbeam of the building's structure.Make the rooftop curb's sealingsurface level using angle bracketsadjusted by screw bolts, locatedaround its perimeter. Place theadhesive seals on the curb's sealingsurface (perimeter and crosspieces). Make the rooftop leak-tightaround the curbs before installingthe unit, in compliance with currentconstruction standards.Note: The unit must be installedperfectly level to ensurecondensates flow from thecondensate tray.The rooftop unit nests into the curband is supported by it. Position theunit, taking care to comply with theindicated directions: the unit'sdischarge and intake openings mustmatch those of the curb.1 = FrameRT-SVX20B-E49
