Beware of what you wish for!

It is a commercial undercounter machine which will do the dishes in under 4 minutes. If set up as a low temp machine, it will need chlorine bleach as a sanitizing agent and uses min 120 degree water. You can plumb it to use hotter water whichi will aid in the drying process, but it also will need commercial liquid soap as domsetic products cannot clean in 4 minutes. I has the same foot print as any standard undercounter unit so it will fit in any kitchen, but you need to bring 208 single phase 4 wire power to it as it does have an in tank sump heater.
It is in no way related to any machine you currently have as it uses a separately mounted pump under the tank.
It also has electronic control boards which, while reliable, may fail and are costly to replace and have to be programmed properly to function in the unit. It would be the best conversation piece you can install in your kitchen as a daily driver and remember too, you can only do one rack at a time so you need storage space for the racks..a flat bottom rack and the standard commercial peg rack.
You can see a picture of what the fromt looks like in the post on the SR24 Hobart machine that I posted.
You might want to ask why he is getting rid of it. If it is running, go and look at it and take off the bottom panel and look for leaks and or any corrosion. You don't want to buy someone else's headache. These machines are costly to restore. There aren't hundreds of thousands of them out there like domestic units and as you know, nearly all the parts have to be gotten from Hobart.
