I did power it up, and the lights and fans all worked and the unit heated. I did not hook it up to a water source (for humidified proofing), but everything looks to be in excellent shape. 208v 3/1 phase, 3 wire + neutral and ground. Requires 1/4 water line for humidified proofing. Either way, you pay the shipper directly (not me).
