Install the coil support bracket on left or right side of the cabinet. 3. Install coil drip flanges on the left or right side of the coil, (same side as horizontal drain pan). 5. Install drain plugs as required in back side of horizontal drain pan. Install plugs in A coil drains to prevent air leaks. 5. Slide coil assembly into cabinet being careful not to tear insulation. NOTE: Be sure A coil pan fits into the support bracket on the back side of the cabinet and that pan is under the flange of the bracket on the right side. The brackets fit over the top edge of the A coil drain pan to hold it when it's put into the horizontal position. 6. Referto Restrictor Orifice Selection and change restrictor if necessary, then install coil access panel. Cabinet can now be placed on it's side for horizontal airflow. Suspended Cabinet Installation 1. If the cabinet cannot be supported on a frame or shelf, it may be suspended. 2. Use metal strapping or threaded rod with angle iron supports under the auxiliary drain pan to suspend cabinet. These supports MUST run parallel with the length of the cabinet (Figure 5 ). 3. Ensure that there is adequate room to remove service and access panels after installing supporting brackets. 4. Place Styrofoam blocks in auxiliary drain pan to support cabinet. Duct Connections Supply Duct Supply duct must be attached to the outside of flange on outlet end of unit. Flexible connectors may be used if desired. Maintain clearances from supply duct to combustibles when heaters are installed. See Figure 1 and unit rating plate. Return Duct Return duct should be attached to bottom of unit using sheet metal screws or other fasteners. 3[._J Electric Furnace I Installation Instructions 4 / Horizontal Drain Pan Figure 1 Coil Support Bracket Horizontal Drain Pan (Right Hand Air_) \ (Left Hand Airflow) il Support Bracket Coil Access Panel \ Drip Flanges (Left Hand Airflow) Drip Flanges (Right Hand Figure 5 Horizontal Installation Field-Fabricated Drain Pan Supports MUST run parallel with blower cabinet =-_ _J Coil Support Bracket (Left Hand Airflow) Horizontal Drain Pan (Right Hand Airflow) 38-20-06 Airflow) Filter Installation Filters must be field supplied. The blower cabinet is set up for an internal filter or a remote filter grille or other means may be pro vided. Refer to ACCA Manual D for remote filter sizing. To install an internal filter, remove screw securing filter door and slide filter into unit. Some filters are marked for airflow direction, make sure arrow points towards blower if marked. Washable filters are offered as an accessory. Disposable filter sizes are listed in Filter Static Pressure Drop Table. Condensate Drain The unit is provided with 3/4" National Pipe Thread (NPT) condensate drains. (Figure 1). Any drain can be used as a primary or secondary drain. Condensate drain lines should be insta!led in a manner that does not obstruct access to the filter. There is a secondary drain fitting supplied with the unit that will convert any of the primary condensate drain connections into a secondary drain connection. This fitting should be insta!led in any of the primary drain connections to convert it to a secondary drain. 1. Connect the drain lines to the appropriate drain fittings. 3/4" PVC or other type of drain line may be used. The drain line must not be smaller than the drain fitting. 2. Insta!l a trap in the drain line below the bottom of the drain pan and pitch the drain lines down from the coil at least I/4" per foot of run. Horizontal runs over 15 feet long must also have an anti-siphon air vent (stand pipe), installed ahead of the horizontal run. An extremely long horizontal run may require an oversized drain line to eliminate air trapping. 442 01 2204 01 I Electric Furnace Installation Instructions 3. Routetotheoutsideortoafloordrain, laundrytrayorwaste Condensate Drain to Waste Line line (sewer). Check local codes before connecting to a Figure 6 1 sewer line. 4. Insulate drain lines where sweating could cause water damage. 5. If a gravity drain cannot be used, install a condensate pump. Install the pump as close to the indoor section as possible. SpecialNoteFor DownflowInstallations For downflow installations, a secondary overflow drain connection must be installed to prevent water from dripping onto live electrical components. Use the secondary fitting on the evaporator coil. Waste Line Connection If the condensate line is to be connected to a waste line, an open trap must be installed ahead of the waste line to prevent escape of sewer gases. NEVER CONNECT THE DRAIN LINE DIRECTLY TO A WASTE LINE. ALWAYS INCLUDE AN AIR GAP AND TRAP, (Figure 6). Be sure to keep the trap filled with water during the winter or off season. Restrictor Orifice Selection A restrictor orifice is located in a fitting at the distributor. The factory installed restrictor orifice is identified on the unit rating plate. The restrictor orifice may require changing to obtain best performance. Refer to the re...
