An Excellent Find!
It was and still is for the most part, a pleasure to work on any unit that is installed in a church setting where the usage on the machines is so light compared to what they were engineered to be put trough. Not to mention the cleaner environment!
I cannot tell you how many UM's I worked on and rebuilt over the years. While they used to be in great demand in the NYC area,as places like Dunkin Donuts and other donut and coffee shops made the transition to paper products, most undercounter and even some counter level SM/LM series machines slowly disappeared. In addition, most manufacturers, or at least Hobart replaced them with the normal sized units we see today or should I say, saw before the tall tubs came out!
The UM was a great machine no matter where it was used. Totally iron clad and tank like in its build.
It looks like those extra legs will bring it up to standard counter height so it will do fine in your normal kitchen setting, You will just have to get some kind of kickplate made up to cover the opening.
The short cycle will do a good job of cleaning even with a domestic powdered detergent and at least 140 degree water.
Of course the hotter the water the better results. If you changed it to the KD10 setup, that longer wash time will cool the water off even more and then you will have a problem with the drying.
I would suggest that you insulate the tank well and stay with the short cycles. If you have the room under the cabinet or somewhere close by, like in the basement under the machine, get yourself one of those 6 gallon 115 volt hot water heaters and have it bump up your domestic supply to the maximum setting on the tstat. That will ensure that the UM gets the hottest water possible.
I had one in my mom's basement and we always had our hot water at the max setting and I had many cycles at 165 and it flash dried the dishes well and without any jet dry! Of course the great soft water in NYC helped!
I also had the pumped drain on it using a KD12 motor and pump setup. I DID use a WM-1 series timer and wiring harness to make it work as it would run the pump continuously from start to finish and I had installed a drain solenoid in the drain line after the KD12 pump without any damage being done to the pump.
When we had big holiday dinners, I would be bringing up the first tray or 2 of cleaned dishes before the table was totally cleared off between courses. Always amazed the relatives with that move! Most holidays, the KDC21 was hardly used. It got maybe one load at the end of the night with the dessert plates and coffee cups!
You will love the UM for sure and if you want to, you could probably piggy back a KD10-14 top rack on the UM's lower rack to expand the glass and cup washing capacity. Or you can put half a rack of dishes and then the cup rack in and work it that way.
No matter what, it will be fun and a conversation piece.
