the vent wedge (6) under the silicone

Remove the vent wedge (6).
✱
In the gap (4), top up the electrolyte to the
brim.
✱
Fill the new membrane cap (2) with three
drops of electrolyte to "lubricate" the O-
ring in the membrane cap. This will
prevent the sensitive PTFE membrane (1)
from being damaged by the glass
membrane (3).
✱
Place the membrane cap (2) on the
thread and screw it on with a quarter
turn.
Attention:
Do not screw the membrane cap
all the way down, as this could
destroy it!
