Nota
Este es el procedimiento para sustituir el supercolector, el compresor y el tubo del aire acondicionado que va del supercolector al compresor, utilizando el adaptador de enjuague de residuos de la bomba de calor del climatizador 1838504-C0-A, 1838504-E0-A o 1838504-N0-A. Al enjuagar el tubo del aire acondicionado del supercolector al climatizador y el conjunto del climatizador, estos dos componentes pueden reutilizarse. Este procedimiento se utiliza cuando el compresor ha fallado debido a un problema mecánico que ha provocado la aparición de residuos en el sistema de aire acondicionado.Si el adaptador de limpieza de residuos 1838504-00-B está disponible, siga el procedimiento descrito en A/C Compressor and Supermanifold (Remove and Replace).
