Applying too much heat to any tube can melt the tube. Service personnel must use the appropriate heat level for the size of the tube being brazed. NOTE: The use of a heat shield when brazing is recommended to avoid burning the serial plate or the finish on the unit. Heat trap or wet rags should be used to protect heat sensitive components such as service valves and TXV valves. 1. Loosen the 13/16 nut 1 TURN ONLY to allow high pressure tracer gas to escape. No gas indicates a possible leak. 6 7 2. After the gas has escaped, remove the nut and discard the black or brass cap. 3. Remove the check piston to verify it is correct and then replace the piston. See piston kit chart in instructions. 4. Use a tube cutter to remove the spin closure on the suction line. 5. Remove the tailpiece clamped to the exterior and slide the 13/16 nut into place. 6. Braze tailpiece to the line set liquid tube. WHITE TEFLON SEAL PISTON TAILPIECE 13/16” NUT PLASTIC or BRASS CAP Figure 1 7. Insert the suction line into the connection, slide the insulation and the rubber grommet at least 18" away from the braze joint. Braze suction line. 8. AFTER THE TAILPIECE HAS COOLED, confirm position of the white Teflon® seal and hand tighten the 13/ 16 nut. 9. Torque the 13/16 nut to 10-25 ft-lbs. or tighten 1/6 turn. Excessive torque can cause orifices to stick. Use the proper torque settings when tightening orifices. 10. Replace suction line grommet and insulation. RUBBER GROMMET SUCTION LINE WITH SPIN CLOSURE Figure 2 Downflow Conversion NOTE: ATUF models should not be converted to Downflow applications. “D” nomenclature models are factory equipped for “Dedicated Downflow” operation and no field conversion is required. Conversion to downflow MUST be performed in an area that allows access to all sides prior to placing the air handler in its final location. To prevent the evaporator coil pan from “sweating” the DPI accessory insulation kit is to be used when performing this conversion. NOTE: The DPI kit is not supplied with this product and is to be purchased separately. See Table 7 for the correct DPI kit. ARUF, ATUF or ARPF Model Insulation Kit 1729 / 1824 DPI18-30/20 3030 / 1931 / 3636 DPI36-42/20 3642 / 3743 / 4860 / 4961 DPI48-61/20 Table 7 Refer to Figures 3 through 5 for the location of the components referenced in the following steps. Figure 3 illustrates the new installation location for the removed components. 1. Before inverting the air handler, remove all access panels, the coil rear channel bracket, and the filter close-off panel. 2. Remove the evaporator coil and the horizontal drain pan. Discard horizontal drain pan. 3. Install the provided plastic plug into the vacated access panel. 4. Remove the two (2) zee coil support brackets and insulation retaining brackets. 5. Remove the tie bracket. 6. Install the DPI Insulation Kit onto the bottom of the drain pan. NOTE: The filter provision is not applicable in THIS downflow application.

Install the tie bracket. 9. Install the rear channel bracket. 10. To prevent possible condensate “blow off” the insulation retainers are to be laid into the evaporator coil pan as shown in Figure 4. 3” FLAT INSULATION RETAINER (BOTH SIDES) 3” FLAT INSULATION RETAINER (BOTH SIDES) Figure 4 To complete the conversion, slide the evaporator coil into the chassis and attach the three (3) access panels.

Horizontal Conversion Dedicated Downflow models are not suitable for horizontal application and must not be used for this type of installation. The only field modification required for conversion to “Horizontal Right-Hand” is the removal of the plastic knockouts in the horizontal panel drain connections. To prevent the horizontal drain pan from sweating in high humidity applications, it is recommended that a DPIH insulation accessory kit be used. NOTE: The DPIH insulation kit is not supplied with this product and should be purchased separately. See Table 8 for the correct DPIH kit.

Conversion to downflow MUST be performed in an area that allows access to all sides prior to placing the air handler in its final location (See Figure 6). DPIH KIT SECONDARY DRAIN PRIMARY DRAIN Figure 6 1. Remove the (3) air handler access panels. 2. Remove the “J” shaped bracket that retains the evaporator coil. 3. Remove the flowrator from the lower left side access panel and slide out the evaporator coil and horizontal drain pan. 4...
