SOSTITUZIONE DEL FUSIBILE MECCANICO 

 

Avvertimento !

 

Tutte le operazioni di collegamento o manutenzione devono essere effettuate con serranda chiusa e in assenza di 

tensione. 

 

Funzionamento 

La sostituzione del fusibile si rende necessaria ogni volta che la temperatura di picco all’interno della condotta, abbia 

superato i gradi centigradi indicati sul fusibile stesso. Una linguetta indica lo stato del fusibile (fig.9), quando scompare 

dentro il corpo in plastica porta fusibile (fig.10), è necessaria la sostituzione del fusibile. 

 

 

 

 

 

 

 

Procedimento: 

Assicurarsi che la serranda sia disarmata verificando visibilmente che 

l’indicatore 

sulla leva indichi il simbolo ]-[ 

presente sul carter. In caso contrario, agire sul pulsante di test per chiudere manualmente la serranda. 

Rimuovere la copertura plastica trasparente svitando la vite di fissaggio centrale (fig.11) 

Svitare le 2 viti con testa a croce ed estrarre il meccanismo di rilascio dalla piastra. 

Sostituire il fusibile comprimendo la molla e agganciandolo ai due perni sporgenti (fig.12)
