the service manual covers all this, get one.
or read the side if the cap and it tells you that ,oops gone.
uF and volts AC
no country told and AC power is not the same all over earth a fine dream by MR Tesla, (RIP)
all I can do is guess any of that, 230vac or 250vac or?
model stated is not a heatpump.
not sold now,
scu10b42-1a
10 = seer year 1997 made? seer 10 is mostly banned.
42 = 42000 BTU .
the dual cap for fan and compressor on the out door pad?
that?
I found the install manual SCU (era) and no parts list wiring diagrams yes.
https://inspectapedia.com/aircond/Armstrong-SCU-Series-Air-Conditioner-Manual.pdf
the parts lists are missing at makers site
https://www.armstrongair.com/
ask them for the parts list. your SCU. (by tons/btu and seer) etc.
that PAD units come on as TON ratings, and the cap must match the compressor and the fan there. or fails. and line voltage not told
(my 5ton AC THE CAP FAILS EVERY 3 YEARS) LIKE A CLOCK.
the maker ended support on old SCU10 series.
seems so. 20+ years old. as most are gone now. R22 phased out.
some laws in some countries ban support for that old of AC
even make did as I can see. (gone)
decodes of models then.
The Armstrong SCU-10, a SEER-10 split system AC using R-22 refrigerant, as an AC series was discontinued before 2020. Models included the Armstrong SCU10B12A1012,900 SCU10B24A SCU10B30A SCU10B36A SCU10B42A SCU10B48A SCU10E18A SCU10E24A SCU10E30A SCU10E36A SCU10E42A SCU10E48A SCU10E60A - where the last two numeric digits are a very rough approximation of the SCU's BTUh rating.
no number if front is gen1.
2SCU is gen2, and so on.
gen 4 is now.
no serial told but the decode is here (yy= 97?
