Wow, never seen a -1 post count, maybe this one will make it zero?
Anyway, Reno, I too am of like mind on wanting to see equipment (if used, which most resturaunts are heading for do to high cost of new), or at the very least detailed cut-sheets. The 120/208/240 rating sounds like it was to be a 4-wire appliance. Often manufactures will throw out some wild numbers in terms of rating like, 110/230, what does that mean? In your case they may have been attempting to make it clear that you could use 208, or a 240 system voltage. But normally it would be typed in as 120/240 4-wire. (3 system and an EG)
