I've got one! and you have to keep trying different levels of adjustment on that long rod it's a bugger but I got there in the end the instructions aren't much good the following proves it it's a copy of the instruction on what you are trying to do. Persevere these cisterns have built in overflow so keep adjusting the rod up and down the unit float works it seems on a ratchet system. There was a picture beside the instructions below but never copied. Doesn't show much anyway, who ever took the picture if they had got further away you wouldn't be able to see it at all.
