Origo canister details
One side of the SS mesh in the center should have a dimple on one side and that's the side you put downward when you tilt it about 45 degrees to pour in the alcohol from a plastic non-dribble container. Take it slow. Their instructions say that when you sit the canister on its side and see liquid alcohol about to run over the lip, that's full enough.
We find that we can go for almost a week on one fillup, depending on how much burn time we average, of course. Note that alcohol will evaporate out around the closed shut-off slider when not using it for a few weeks. There is an optional rubber lid that you can put on each canister to prevent or at least slow down this loss when you are away from the boat for a week.
I tried to get some photos of the canisters on our Origo... I need to re-read the manual on closeups...
Perhaps you have a canister where ther screen dimple was missed through some sort of QC foulup when it was assembled (?).
