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..

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
