• Is it important to figure out the power source?
• Yes.  When buying used restaurant equipment it is integral that you figure out the:
  
• power source
• natural gas
• LP gas
• single phase electric or three phase electric. 
  
• may determine whether or not the equipment will work in your facility. 
  

• What are the possibilities on three phase?
• There are a few possibilities on three phase:
• Does your building perhaps have three phase but your business doesn't have it? 
  
• If this is true then it's merely a line pull by a licensed electrician.
  
• If you don't have three phase you can look at purchasing a phase converter. 
  
• You will want to talk to manufacturer service technician and/ or local electrician about using a phase converter with specific equipment. 

But, this opens up opportunities in purchasing specialized used restaurant equipment.
