I see that specific poster's dialog in your response, only. His actual
postings get filtered autiomatically here.

The unit is unlikely to go up in flames, for good reasons. 

As a technician, you'd be advised to follow industry standards in

A hipot is not impossible to arrange, locally, if you don't have the
equipment yourself.
