Nope, no plate with anything printed on the back, nor underside. Actually, here are some pics in case anyone here recognizes this oven... http://veisystems.com/stuff/APS-GF12-01.jpg http://veisystems.com/stuff/APS-GF12-02.jpg Considering that the literature for the newer models say they're 220V single-phase (3-phase option), and considering the size of this oven (3 zone conveyor), I'm pretty sure 120V won't cut it.
