Remarque
Il s'agit de la procédure de remplacement du supercollecteur, du compresseur et de la conduite de climatisation reliant le supercollecteur au compresseur, à l'aide de l'adaptateur de rinçage de débris pour pompe à chaleur CVC 1838504-C0-A, 1838504-E0-A ou 1838504-N0-A. Le rinçage de la conduite de climatisation reliant le supercollecteur au système CVC et de l'ensemble de système CVC permet leur réutilisation. Cette procédure est utilisée lorsque le compresseur tombe en panne en raison d'un problème mécanique ayant entraîné la présence de débris dans le système de climatisation.Si seul l'adaptateur de rinçage des débris 1838504-00-B est disponible, utilisez la procédure décrite dans A/C Compressor and Supermanifold (Remove and Replace).
