I have a file with many sets of duplicate records, I need to restore the same file with duplicates removed, but one record preserved from each set.

When I apply sum fields=None it removes all the records.

I dont think sum fields=none removes all the records. It does keep first of the duplicate record, which it determines on the basis of SORT/MERGE criteria.
Try giving a sort on the fields which form your criteria of duplicate and give sort fields=none. It should work
