Hey all, we are a coffee catering company and believe in the freshly ground beans, measuring and timing each shot. So we take our coffee seriously. However we are pretty new at this and we are still trying to find the best ways to do things. We have the appia single group semi auto Nuova Simonelli. We store it inside after each event but it is unplugged. So about twice a month it gets plugged it and used for 2-4 hours then cleaned and shut down until the next event. What we are wondering is should we set it up and run it once a day? Always have it turned on? Or is our current situation the best for it?

I have a friend who uses a Rancilio R-series for a cart that he takes to events during the summer season, and he does pretty much what you do although his machine is typically running for about six hours. Afterwards, he turns it off cleans it thoroughly and stores it until the next event, where he sets up and powers up the machine at least 45 minutes before he starts serving. He also has a generator he takes for situations where the power can be unreliable (events at parks and open-air markets).

I think that should be fine. I don't know if this is a double boiler machine, if it is I'd run the brew boiler enough to replace the water with fresh water each time you bring it out if it has been sitting for a week or more.

The Appia is a single boiler HX machine. It's ideal for mobile catering jobs due to its portability and power requirements. The most important thing to do if keeping it stored for extended periods is to backflush the group until clean, purge the steam wand after every use, and drain the boiler and heat exchanger. Also make sure to feed it softened water. When firing up the machine at an event pull the right side panel and disconnect one wire from the high-limit thermostat (Not the autofill probe) so you can fill the boiler with water without powering the heating element. Once it's full, shut down and plug the thermostat back in. Power up and you're back in business. If it were my machine, rather than do all this I would just put it to use in my own kitchen in the mornings and leave it on all the time. Then you can just unplug it and take it to events as you need to. Good luck
