I cleaned it as they recommend and did my first run with the vinegar and water. I bought an electric single stove specially for the distiller. The distiller performed excellently I can't wait for my mash to get fermented for my very own, first time liquor making. I had a sump pump from an old garden fountain, submerged it in a 5 gal. bucket full of tap water and used it for the condensator coils, to keep the water cool. All I can say it is awesome, can't wait for the real thing.
