Serial numbers may be listed on the ID tag of the front panel of the fryer. If no ID tag is present or
the ID tag was replaced with an upgrade control kit, the original serial number is etched onto the front
right side of the fryer pot rim. A serial tag from an upgrade control kit can NOT be used to determine
useful life.
