yeah their 3 phase apart from the ritmo which is either 240v or 110v, you need a 3 phase genny that is at least 12.5 kva or if a diesal genny then 20kva or more, if you run from a barrel you want a 3/4 geka fitting on the bottom and a short (about a metre) of 3/4 hose going into the machine
PWI when you say you have a tap at the bottom of your barrel do you mean just a standard outside tap
