What we could not confirm
- The era not stated format has no source we could check; it is shown for completeness only.
- The era not stated format is documented but not decodable here: no pattern (no date encoded, or format unknown).
- Manufacture date is NOT encoded in the serial (per Fujitsu, relayed by building-center). Official serial lookup at access.fujitsugeneral.com (200, behind a Turnstile human check) returns manufacture + install date for registered units; otherwise call Fujitsu service (866) 952-8324. Building-center suspects the 3-letter prefix encodes the year but has not cracked it: LTN019205=2014, KRN016785=2013, LUN038094=2014, FTN012306=2017, KSN021789=2014, EXN029093/EXA028248=2019, AEN008487=2016, DDN002064=2006, C001294=mid-1990s.
