If the air handler is installed in an unconditioned space, sealant should be applied around the electrical wires, refrigerant tubing, and condensate lines where they enter the cabinet. Electrical wires should be sealed on the inside where they exit the conduit opening. Sealant is required to avoid air leakage and condensate from forming inside the air handler, control box, and on the electrical controls. The air handler must be installed in such a way as to allow free access to the coil/filter compartment and blower/control compartment. The air handler must be installed in a level position to ensure proper condensate drainage. Installation learances Non-Duct eturn loset Installation The air handler can be installed in a closet with a false bottom to form a return air plenum or be installed with a return air plenum under the air handler. Louvers or return air grilles are field supplied. Local codes may limit the application of systems without a duct return to singlestory buildings. 3

4 For an air handler installed in a closet with a louvered return opening, the minimum open area for the louvers will be as shown below. 8" and 2" (.7 cm and 6 cm) models 30" and 36" (76.2 cm and 9. cm) models 2", 8" and 60" (06.7 cm, 2.9 cm and 2. cm) models If the free area is not known, assume a 2% free area for wood louvers or a 7% free area for metal louvers or grilles. Using the louver dimensions and the 2% or 7% assumption, determine if the louver open area meets the minimum open area listed in the previous chart. If the return air plenum is used, the return air grille should be immediately in front of the opening in the plenum to allow for the free flow of return air. When the air handler is not installed in front of the opening, there must be adequate clearance around the air handler to allow for the free flow of return air. The unit clearance from a combustible surface may be 0". Allow a minimum of 2" (6 cm) in front of the unit for service clearance. Do not install the air handler in a location that violates the instructions provided with the condenser. If the unit is located in an area with high ambient temperature and/or high humidity, the air handler may have condensation on the casing. n these installations, a wrap of 2" (. cm) fiberglass insulation with a vapor barrier is recommended. onsult all appropriate regulatory codes prior to determining final clearances.

Make sure the orifice is free to move in the fitting.. eplace the brass hex nut. NTE: vertightening the brass hex nut will crush the gasket and may result in a system leak or stuck piston. 6. Dispose of/recycle all packaging and unused parts. onnect efrigerant Lines efrigerant lines must be connected by a licensed, EPA certified refrigerant technician in accordance with established procedures. IMPTANT: onnecting refrigerant lines must be clean, dehydrated, refrigerant-grade copper lines. Air handler coils should be installed only with specified line sizes for approved system combinations. Handle the refrigerant lines gently during the installation process. Sharp bends or possible kinking in the lines will cause a restriction. Do not remove the caps from the lines or system connection points until connections are ready to be completed. WANING Goodman This product is factory-shipped under pressure. Follow these instructions to prevent injury. 8

9 AUTIN To protect the unit when Goodman welding close to 3the painted surfaces, the use of a quenching cloth is strongly advised to prevent scorching or marring of the equipment finish. Solder with a minimum of % silver is recommended. Tubing Preparation All cut ends are to be round, burr free and clean. Failure to follow this practice increases the chances for refrigerant leaks. The suction line is spun closed and requires pipe cutters to remove the closed end. Post Brazing Quench all welded joints with water or a wet rag. Piping Size For the correct tubing size, follow the specification for the condenser/heat pump. Special Instructions This coil comes equipped with a check style flowrator for refrigerant management. For most installations with matching applications, no change to the flowrator piston is required. However, in mix-matched applications, a flowrator piston change may be required. See the piston kit chart or consult your local distributor for details regarding mix-matched piston sizing. If the mix-match application requires a different piston size, change the piston in the flowrator on the indoor coil before installing the coil and follow the procedure shown below. IMPTANT: Torch heat required to braze tubes of various sizes is proportional to the size of the tube. Tubes of smaller size require less heat to bring the tube to brazing temperature before adding brazing alloy. 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. NTE: 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 avoid damage to heat sensitive components such as service valves and TXV valves.. Loosen the ¹³ ₁₆" nut one turn only to allow high pressure tracer gas to escape. No gas indicates a possible leak. 2. After the gas has escaped, remove the nut and discard the black or brass cap. 3. emove the check piston to verify it is correct and then replace the piston. See the piston kit chart in the instructions.. Use a tube cutter to remove the spin closure on the suction line.. emove the tailpiece clamped to the exterior and slide the ¹³ ₁₆" nut into place. 6. Braze the tailpiece to the line set liquid tube. 7. Insert the suction line into the connection. 8. Slide the insulation and the rubber grommet at least 8" (.7 cm) away from the braze joint. 9. Braze suction line. 0. After the tailpiece has cooled, confirm position of the white Teflon seal and hand tighten the ¹³ ₁₆" nut. AUTIN Goodman 8 Excessive torque can cause orifices to stick.

Disconnect Goodman ALL power 6 before servicing. Failure to do so may cause property damage, personal injury or death. This section references the operation characteristics of the WAHMV model motor only. The EM control board is factory-set with DIP Switch in the N position and all other DIP switches in the FF position. For most applications, this setting is to be changed according to the electric heat size and the outdoor unit selection. The WAHMV product uses a General Electric EM TM motor. This motor provides many features not available on the traditional PS motor. These features include: Improved Efficiency onstant FM Soft Start and Stop Improved Humidity ontrol Motor Speed Adjustment Each EM TM blower motor has been preprogrammed for operation at distinct airflow levels when operating in cooling, heat pump heating, backup heating (electric heating) and backup plus heat pump heating. Each mode has levels to deliver different airflow FM [L/s]. The adjustment is performed by changing the DIP switch(es) either to an FF or N position. 22
