841890-UIM-B-06125SECTION IV: COIL INSTALLATIONFURNACE ASSEMBLY - MC & FCThese coils are factory shipped for installation in either upflow or down-flow applications with a minor conversion.For Upflow Application:1. Position the coil casing over or under the furnace opening asshown in Figure 5 after configuring coil flanges as required see“Coil Flange” section below and refer to Figure 7.2. Slide up the sides and back flange and tight the 6 screws that holdthem. Refer to Figure 6.3. Unscrew the front flange and move it to the top to align it to therest of the flanges allowing to screw it back to the brace using the2 holes in the bottom of the front flange. Refer to Figure 6.4. Place the ductwork over the coil casing flange and secure.Seesections on "Refrigerant L ine Connections" and "CondensateDrain Connections". One mounting plate is provided with the coils.For Downflow Application:1. Position the coil casing over or under the furnace opening asshown in Figure 5 after configuring coil flanges as required see“Coil Flange” section below and refer to Figure 7.2. Remove all 8 screws from flangs and position them at the bottomof the casing for the alternate position. Refer to Figure 7.3. Place the ductwork over the coil casing flange and secure.Seesections on "Refrigerant Line Connections" and "CondensateDrain Connections". One mounting plate is provided with the coilsCOIL FLANGE - FOR DOWNFLOW AND HORIZONTALLEFT KIT INSTALLATIONThe coils include removable flanges to allow proper fit up with furnacesor two-piece air handlers having various inlet and outlet flange configu-rations. The two flanges are attached to the top of the coil in the factoryduring production. If the installation requires the flanges to be moved tothe bottom of the coil, remove the screws attaching the flanges to thetop of the coil casing. Next, install the flanges to the bottom of the coilcasing using the same screws. Refer to Figure 7.The additional holes in the upper area of the flanges may be used toattach the coil to the furnace or two-piece air handler. This is done byinstalling field-supplied screws through the flanges into the inside of thefurnace or two-piece air handler casing.The front flange is also designed so that it can be rotated 180 degreesand re-installed. In this mounting configuration the front flange willextend further to the front of the coil casing to accommodate furnacesor two-piece air handlers that have a greater front-to-back dimensionthan the coils.FIGURE 5: Vertical ApplicationsUPFLOW DOWNFLOWFurnaceFurnaceFIGURE 6: Coil Flange PlacementWhen installing this coil with an oil furnace, a minimum of six inchesclearance should be maintained from the top of the heat exchanger.FIGURE 7: Coil FlangeNOTICEAlternateFlange LocationFactoryFlangeLocation
