Uninspiring start! The unit arrived from upside down in the open box from the FedEx truck.  The bottom of the unit is dented and stained with some white material - did someone leak from the unit? FedEx driver indicated that the box for not packaged and taped securely.  
According to instructions from the customer service I have to wait 48 hour before plugging the unit to allow to come to room temperature. Will post an update after plugging in.
