Warning

Solo i tecnici che hanno completato tutti i corsi di certificazione richiesti sono autorizzati a eseguire questa procedura. Tesla raccomanda ai tecnici di fornitori di terze parti di seguire una formazione equivalente prima di svolgere la presente procedura. Per maggiori informazioni sui requisiti dei Tecnici Tesla, o per le descrizioni degli argomenti richiesti per i tecnici di fornitori terzi, vedere i Requisiti per certificazioni HV. Ogni volta che si maneggia un raccordo, una barra di distribuzione o un cavo ad alta tensione è necessario indossare idonei dispositivi di protezione individuale (DPI) e guanti isolanti per l'alta tensione con classe di protezione minima 0 (1000 V). Per ulteriori informazioni sulla sicurezza, fare riferimento alle Note tecniche relative ai rischi dell'alta tensione TN-15-92-003, "High Voltage Awareness Care Points".

CAUTION
I componenti del sistema di controllo termico della Model Y hanno delle specifiche operative molto strette e possono guastarsi se non si osservano con attenzione le procedure di manutenzione. NON basarsi sulla passata esperienza con altri sistemi di controllo termico; leggere il Manuale di manutenzione e non discostarsi dalle istruzioni fornite.
Note
This procedure requires the A/C Refrigerant (Recovery and Recharge) procedure to be performed. If not already automatically added to the Service Visit, add correction code 18200102 as a separate correction within the same activity to the Service Visit.
