These instructions are intended as a general guide and do not supersede local codes in any way. Consult with local authorities having jurisdiction before installation. Read this installation manual and all safety messages prior to installing the evaporator coil. Check coil for shipping damage and verify the contents of the box containing the evaporator coil. If you should find damage, immediately contact the last carrier. Verify the efficiency performance requirements, such as SEER, EER, and/or HSPF, are appropriate with the matched condensing or heat pump units. Check outdoor unit manufacturer for proper line sizing. Coils are shipped with a 10 psi dry air holding charge. Puncture rubber plug on suction line to release charge before removing plugs. The absence of pressure does not verify a leak. Check the coil for leaks before installing or returning it to your wholesaler. Position the coil on the outlet of the furnace using sheet metal screws. Drain pans are made of a polymer that can withstand temperatures up to 450°F. Maintain a 3" clearance on oil or drum type heat exchangers and 1½" on sectionalized heat exchangers. Coil should be level, or pitched slightly toward the drain connection. Airflow face velocity above 350 ft/min is not recommended for downflow or counterflow applications due to potential water blow-off.

Company 215 Metropolitan Drive West Columbia, SC 29170 INSPECTION OF SHIPMENT Upon receipt of equipment, carefully inspect it for possible shipping damage. If damage is found, it should be noted on the carrier's freight bill. Take special care to examine the unit inside the carton if the carton is damaged. Any concealed damage discovered should be reported to the last carrier immediately, preferable in writing, and should include a request for inspection by the carrier's agent. If any damages are discovered and reported to the carrier DO NOT INSTALL THE UNIT, as claim may be denied. Check the unit rating plate to confirm specifications are as ordered. VERTICAL Vertical A-Coils are designed for upflow and downflow applications. Vertical drain pans have drain connections on the right and left front side of the evaporator coil. Airflow face velocity above 350 ft/min is not recommended for downflow applications due to potential water blow-off. Refer to Specification Guide for limitations. In downflow applications, aluminum foil tape must be applied to seal the top edge of the insulation to the cabinet. This tape will prevent the possibility of the insulation delaminating and blocking airflow. HORIZONTAL Horizontal A-Coils are designed for horizontal applications only. Horizontal A-Coils 17.5" and taller include furnace plate adaptors to facilitate proper fit with furnaces of different widths. Proper performance for Horizontal A-Coils with top connections requires that the air flows out through the side of coil where the top connections are located (Figure 1). FIGURE 1 Air Flow Direction for Horizontal Coils with Top Connections Airflow ONLY top connections Airflow ONLY 2 MULTI-POSITION Multi-Position A-Coils come factory installed with a vertical and horizontal drain pans and can be configured for upflow, FIGURE 3 downflow, horizontal blow-through or horizontal pull-through installations. In the center opening of vertical drain pan, a Multi-Position Configurations metal Inlet Air Restrictor is factory installed and is required for horizontal applications. It may be removed for vertical applications. Airflow face velocity above 350 ft/min is not recommended for downflow or counterflow applications due to potential water blow-off. For horizontal configurations, install splashguard (included) AIRFLOW FURNACE onto the coil outlet, and extend suction line insulation into the SPLASH A. coil cabinet by 2" to prevent moisture from dripping onto the GUARD insulation (the rubber grommet may need to be moved). Splashguard installation is not required for vertical configurations. Bottom flange of guard should rest on pan and sides screwed to the duct flanges. See page 4, Figures 4 and 5 for splashguard instructions. FURNACE TRANSITION In downflow and counter flow configurations, aluminum foil tape must be applied to seal the top edge of the insulation to SPLASH GUARD B. the cabinet. This tape will prevent the possibility of the insulation delaminating and blocking airflow. In horizontal pull- 12 min through and counter flow configurations, a minimum 12" transition is required in front of the coil as shown in Figure 3. TRANSITION This is required to ensure proper airflow distribution and to FURNACE reduce pressure drop. C. Coils that are 20" or less in height and are installed in a cabinet with a height of 25-½" or greater do not require a transition; all other coil models require this transition. Coil should be level, or pitched slightly toward the drain connection. It is recommended to add silicone caulk between drain pans to prevent water carryover. Note: Multi-Position A-Coils are also Apply foil tape to top edge of insulation 12 min FURNACE field convertible from left-to-right or right-to-left; see page 5 for D. instruc ons on field conversion for horizontal airflow.

Caution: These holes are for manufacturing purposes only. DO NOT use for installation! Fasten splash guard to duct flanges with (4) sheet metal screws. (2) on each side. Screws can be installed from the inside or outside. First set of mounting holes are used when horizontal drain pan is flush with housing. Second set of mounting holes are used when horizontal drain pan is shorter than cabinet height. 4" min. Angle splashguard to ensure proper water drainage back into horizontal drain pan. Splashguard should overlap the horizontal drain pan by at least 4". Fasten splash guard to duct flanges with (4) sheet metal screws. (2) on each side. Screws can be installed from the inside or outside. 4 MULTI-POSITION (field conversion) Field Conversion Instructions from Left-to-Right or Right-to-Left Airflow Note: This applies only to models available in multi-position; typical horizontal left-to-right conversion is shown. FOR EACH STEP, REFER TO FIGURE 6: Remove front panels. Remove the top tie bar and pull the coil assembly from the housing. Remove the horizontal drain pan, and re-install it to the opposite side of the coil (Note: horizontal drain pan must have drain plugs tightly closed in the rear of the unit). Remove the top plate. Remove the water diverter, and re-install it to the opposite slab (Note: If water diverter is attached by screws, remove screws, and bend tab straight or cut tab off). Replace the top plate, and apply sealant to seal any air gaps. Before re-inserting the coil assembly, cut the front flange on the housing and fold it back to allow access to the horizontal drain connections (Note: Copy the factory cut-out on the opposite side of the housing). Slide the coil assembly back into the housing (Note: If unit is equipped with a sheet metal spacer, it must be moved to the opposite side of the housing). Re-install the top tie bar. Re-install the piping panel to the housing. Cut a hole in the access panel to allow access to the horizontal drain connections, and re-install the access panel to the housing (Note: Access panel may need to be notched to allow access to suction header). Seal unused condensate drain connection cutout holes in the front panel to prevent air leakage.

Replacement TXV part numbers are listed below; see kit instructions for change out or installation. Place a wet rag around the suction line at the cabinet during brazing to prevent overheating and damaging the sensing bulb. For optimum performance, reattach and insulate the bulb at a 10 to 2 o'clock position outside of the cabinet to the main suction line no more than one foot from the suction line connection. When changing a system from AC to heat pump or heat pump to AC, check the current TXV specifications to determine if a TXV replacement is required. If the evaporator coil contains a non-bleed TXV and is used with a condensing unit containing a reciprocating compressor, a hard start kit will be required on the condensing unit. Bulb must be insulated from ambient air ( e.g. Foam insulation) IMPORTANT When changing the metering device, ensure the metering device matches the refrigerant type and capacity of the condensing unit. Failure to do so will result in poor performance and possible compressor damage. All coils must be matched properly as listed in the AHRI directory. Cased coils with a piston metering device are shipped with a cap and hex nut over the threaded fitting. Remove the cap and nut slowly, allowing charge to escape, and secure the liquid line stub (attached to cabinet) to the distributor assembly with hex nut. Discard cap. For optimum performance, the piston should be sized to match the recommendation from the outdoor unit manufacturer. If the outdoor unit manufacturer does not recommend a piston size, refer to the piston size chart. When changing pistons, refer to Figure 7 and use the following procedure: Loosen hex nut located on liquid line and separate from distributor assembly. Remove the existing piston from inside the distributor assembly. Insert the desired piston into the distributor assembly. Inspect Teflon O-Ring and replace if damaged. Ensure Teflon O-Ring is in place. Re-install hex nut to body and torque to 10 ft-lbs. FIGURE 7 Piston Assembly Liquid Line Hex Nut Teflon O-Ring Seal Piston Distributor Assembly Coil Cabinet REFRIGERANT LINE INSTALLATION It is recommended to install a filter drier in the liquid line. While brazing, purge the system with Nitrogen to prevent contamination. Evacuate the system to 500 microns to ensure proper air and moisture removal (Note: Deep evacuation or triple evacuation method recommended). Open the suction service valve slowly and allow the refrigerant to bleed into the system before opening the liquid service valve. REFRIGERANT CHARGING INSTRUCTIONS The system must be charged per the outdoor unit instruction manual 6 CONDENSATE DRAIN Coils are equipped with multiple drain connections. Determine the drain connections to be used and note the difference between the primary (green) and secondary (red) openings. Drain plugs are provided for all openings; remove and discard the appropriate plugs with ½" drive ratchet and verify that remaining plugs are tight (2.5 ft-lbs). Attach drain line to pan with ¾" male pipe thread PVC fittings. Hand tight is adequate do not over tighten & do not reduce drain line size! Route drain(s) line so they will not be exposed to freezing temperatures and do not interfere with accessibility to the coil, air handling system or filter. The drain should be pitched downward 1" per 10' with a 2" trap as close to the coil as possible. If line makes a second trap, or has an extended run before termination, a vent tee should be installed after the trap closest to the pan. See Figure 8. If the coil is located in or above a living space where damage may result from condensate overflow, a separate ¾" drain must be provided from the secondary drain connection. Run this drain to a place in compliance with local installation codes where it will be noticed when unit is operational. Condensate flowing from the secondary drain indicates a plugged primary drain. Prime the trap with water. Test line for leaks. Test water flow with unit in operation. An auxiliary drain pan should also be installed under the unit as specified by most local building codes. FIGURE 8 Condensate Drain Vent in this location (before trap) is acceptable as long as proper drainage is achieved Vent must extend a minimum of 2" above the drain pan Drain Pan 2" Min. 3/4" MPT Connector 2" Min. 2" Min. Vent "T" WARNING This product may contain fiberglass wool insulation. Glass wool fibers are known to the State of California to cause cancer. Disturbing insulation during installation, maintenance, or repair may expose you to glass wool fibers and may cause respiratory, skin or eye irritation. For further information on risks associated with fiberglass wool, consult Material Safety Data Sheet available from OEM. IMPORTANT The Clean Air Act of 1990 bans the intentional venting of refrigerant (CFC's and HFC's). Approved methods of reclaiming must be followed. Fines and/or incarceration may be levied for non-compliance.
