If you have the mfg name you can get the wiring info via the internet. I recently found the info on a bunch of 'pre-owned' 5 deck cases for a plan review job. The EE had a 20 amp duplex on the plans!!! (Wrong)
Back many years, we ran a circuit for the compressor, and a circuit for the defrost. 12s on a 20 & 10s on a 30.
IMHO, go to the mfg website, and if the units are 'old', talk to the mfg tech guys.
