Auxiliary Code Breakdown
The auxiliary code is the rst two characters in the serial number. The rst character indicates
the year. Years progress or regress in alphabetical order. The series runs from "A" through "V"
and the letters "I" and "O" are skipped. The second character indicates signicant part changes
within a year. Base is "5" and this number advances for each change.
Note About Ordering Parts
Most assemblies cannot be ordered as complete units; parts in the assemblies generally must
be ordered separately.

socket, Hoshizaki recommends replacement with
