Was a bit confused on how to use. 4 cups or 8 cups of water. E10 vent to 0 then air tight. NESCO should contact user humble little homestead (YouTube user) because she’s saying that 4 cups of water and close airtight vent at E 10 . Which is incorrect. NESCO should have their own video on this canner.  The information in the old pamphlet sucks. But once you get the right info ,8 cups of water E10 to E0 then air tight it’s great.
