Bruce - a very good walkthru video. Sold mine a few years ago but had fun with it while I had it. Mine was a 220V Euro version, Bugsy walked me thru making a voltage reducer.
Yours runs well. All water pumps make a fierce rattle on those I've seen.
Your right about the water pump Scott , it took me a few minutes the 1st time I ran it to isolate that the water pump was the noise, apparently a built in noise with these steam plants , knowing... that I'm ok with it. This one was originally a 220V model as well , I changed it from a 220V series wiring to a parallel 110V wiring setup.
