[air-row]

Im working on an old Hussman condernser unit. Vertical blow style no model or serial number. Im looking for the wiring diagrams . If anyone has any it would be great. Or if you have a model number . thanks

You're not giving us much to go on here.

Is this a "condensing unit" with a compressor, receiver, etc. or is it an "air-cooled condenser" with just a coil and fan(s)? There's a big difference.

Pictures would help, but I think you need a few more posts before you can post pics.

It's a whole condenser. Compressor, receiver, contactor, defrost control , I'd say it's probably 20-25 years old

Then in proper Refrigeration terminology, that would be a "condensing unit".

The only Hussmann condensing units with vertical air discharge that I recall would be in the 10+ horsepower range and up. Essentially, those are skids with a compressor package mounted at the header end of the condenser.

For starters, what is the compressor model number? That would help narrow this down a bit. Also, what's the application and refrigerant? HT, MT or LT?

If it's 20-25 years old, I could have info on it. That's my era.

It's a walk in cooler application. 38 degrees. R22. Tecumse recip hermetic compressor. No nameplates on unit or compressor.

The typical electrical schematics near the end are fairly generic, so whatever it is you're looking for should be in there someplace.
