VENT)
Connect the H

vent port, located at the bottom left of the front
panel, to your hydrogen vent outlet.
During ramp-up, after ramp down and in regular intervals during
operation, the electrolyser depressurises and releases up to 20
litres of hydrogen within 2 seconds with a loud noise through the
vent line. Please wear PPE earplugs when being close to the
devices. Purging is necessary to release the water which has been
extracted from the hydrogen.
