GENERAL iNFORMATiON C(*)QA/DA coils are designed for upflow and downflow furnace/air handler applications. The C(*)QA coils incorporate "single shot" coupling refrigerant connections for easy installation. The C(*)DA coils are furnished with down-turned refrigerant connections, ready for brazing. 4. 5. Read the installation manual supplied with the outdoor unit for refrigerant line connection procedure, required line sizes, and other information pertaining to the system installation. 1. 6. 7. tubing connections Make certain that the air delivery of the furnace/air handler is adequate to handle the static pressure drop of the coil, filter, and duct work. 2. In orifice style models check the orifice size of the coil's expansion device and confirm that it is suitable for application with the intended outdoor unit. 3. Where precise forming of the refrigerant lines is required, a copper tubing bender designed for the size lines used is recom- mended. Avoid sharp bends and contact of the refrigerant lines with metal surfaces. Refrigerant lines should be wrapped with pressure sensitive neoprene or other suitable material where they pass through the raw edges of holes. The coil enclosure (if provided) and suction line must be insulated as needed to prevent condensate from forming and causing property damage. Coil must be level for proper condensate drainage. Do not remove seals from the coil until the are ready to be made. NOTE: Optional cooling/heating equipment must be properly sized and installed in accordance with the furnace manufacturer's specifications and approved recommendations. "Heating only" furnace air circulators may have to be replaced with multi-speed "Heating/Cooling" blowers to upgrade the air delivery (CFM) when an add-on coil is installed. Refer to Coil Specifications for recommended CFM and allow for pressure drop across the coil and filters. 2.

Mark the position of the union nut (match lines on the line coupling and the coil coupling), then tighten the coupling an additional 1/4 turn to ensure a leakproof connection. Use the Torque Values table (below) if a torque wrench is used. On C(*)D coils with TXV where brazing is required to make the line connection it is required to wrap a wet rag around the suction tube between the sensing bulb and the joint being brazed to avoid damage to the bulb. Check the system for leaks. 5. RESTRICTOR Figure g. Wrenches on Distributor Body and Assembly Nut CHANGE=OUT NOTE: If the orifice must be replaced, follow these steps. 1. Connect only the suction line coupling to the coil as indicated in Section 4. 2. 3. 4. 5. 6. Reclaim the holding charge from the coil and suction vapor line through the schraeder port using the methods approved under the Refrigerant Transition and Recovery Certification Program. Open the distributor body by using open end wrenches and turning the swivel nut (smallerwrench) counterclockwise. Remove the restrictor, being careful not to scratch the bore or the distributor body (See Figures 9 and 10). Select the proper size restrictor and place it rounded end down into the distributor Figure 10. Removal of Orifice ..... J body (See Figure 11). Realign the swivel nut and distributor. Start the threads by hand then continue to tighten with the wrenches until a resistance is felt. Figure 11. Restrictor Insertion in Distributor Body Match the position of the nut and then tighten an additional 1/4 turn. If a torque wrench is used, tighten the nut with the values for the 3/8" line. 7.

The indoor coil must be checked to ensure a level installation. Failure to do so may result in improper condensate disposal, causing structural damage, premature equipment failure, or possible personal injury. m Condensate Drain: 1. Thread the 3/4" drain fitting (included) into the lowest tapped hole on the condensate pan. Hand tighten the fitting. If a different configuration is required, use only PVC or similar material for the fitting. NOTE: Overtightening the fitting may crack the drain pan and create a condensate leak. 2. Slip the drain line over the end of the fitting, add the clamp provided and run to a suitable drain. Avoid bending or pinching of the line. 3. During the system checkout, inspect the drain line and connections to verify proper condensate disposal. Air Filter -- Air filters are not provided as an integral part of this coil, however, a filter must be installed upstream of the coil and inspected frequently. When the filter becomes clogged with dust or lint, it should be replaced (disposable type) or cleaned (washable type).The filter should be inspected and replaced or cleaned at least twice during the year, generally at the start of each heating and cooling season. Close=Off Plates and Panels-- Ensure that all electrical power to the furnace and outdoor (condensing) unit is off before performing any maintenance or service on the system. It will be necessary to evacuate the indoor coil and line set prior to charging. Refer to the outdoor unit installation manual for detailed charging instructions. 7. MAINTENANCE AND SERVICE To ensure optimum system performance and to minimize the possibility of equipment failure, the following periodic maintenance should be performed on the coil: 1. 2. The air filter installed with the system should be checked and cleaned or replaced twice per year. Check the coil, drain pan, and condensate drain line for cleanliness at the start of each heating and cooling season. Clean remove any debris as required. and Install the nec- essary air close-off plates around the refrigerant lines and drain line where required. Reinstall all inner and outer panels of the furnace/air handler that were previously removed to install the indoor coil. Refrigerant Charging -- C(*)Q series indoor coils contain a "holding charge" to prevent entrance of moisture and contaminants during shipment. The total system operating charge of R-22 refrigerant is in the outdoor unit and is adequate for the matched listed system including 15 feet of line set. I WARNING: CAUTION: Do not operate the system without having a suitable filter in place in the return air duct system. Always replace the filter with the same size and type.
