Jena Lab Model 1 Power conditioner/Cord

I am interested in Jena Lab Model 1 power cord. But, I am wondering if Model 1 can be used in 220V application. Would be appreciated if anyone with experience in 220V application can answer this question. I already asked this question to Jena Labs a few times & was not able to get response on this one.
I just spoke with Jennifer on the phone, and she said she recently replied to a gentleman asking about 220V operation on the Model 1. The short answer is this: A 120V Model One cannot be used in 220 operation without reconfiguration at the factory. On a semi-related note, I should add that Jena Labs is incredibly good at answering emails.
