I did take the time to give it an overview. I had previously read another document that precluded all "22xxx" models from 50A but did not list that specific number. I looked at your document but quite honestly, hidden in the many lines of fuzzy writing, looking thru 2 year old quadfocals with cataracts...I failed to see that model listed. I DID however go back, concentrate and saw that model number (however minutely) listed.
