Tends distilling equipment that removes alcohol from beer to convert it to near-beer: Turns valves to admit water to condensers. Starts impellers and vacuum pumps, and opens beer inlet valve. Observes meters, and steam-pressure and vacuum gauges, and turns valves to make adjustments required to draw off vaporized and condensed alcohol and return other gases to solution. Starts pump to transfer solution (near-beer) to storage tank or rack room. Inspects hoses, pipes, tanks, and connections for leaks and cleans equipment by flushing with water.
