BLS maintenance training – Replacing the inhalation valve holder and relative inhalation valve

To replace the inhalation valve holder MI/24, it is necessary to take it out from its housing on the inner threaded connection MI/20, making a slight pressure. Replace the component, check the inhalation valve NG/26 and then place it again in its housing, keeping attention to place it straight and with the valve turned into the inner of the mask, checking that the valve surface is free to move.
