How to instal compressor for ac?

[Stowy]

My house is wired and plumbed for central air and actually had a unit running at one point. Previous owners simply removed only the outside compressor. I bought a used one in hopes of getting it to work with existing fittings and power. So after i solder the copper pipes (*2) and give the condensor 220 power what do i do with the small red/black wires coming from my Lennox HS29 18 unit? Is this for the temperature control unit? If so i have an old one do i need to replace with digital? Do i need these wires at all or will it turn on when needed. Basically any helpfull hints would be much appreciated How do i turn it on?

You purged with an inert gas before soldering didn't you? You have to evacuate and charge the unit. You need a license to buy and use the refrigerant. I think you are in over your head already.

Or a troll.

Especially is he used soft (plumbing) solder.

Oughta be matching red and black wires some where. That's the best I can do without being there to see it.

Oh, since it's an AIR conditioner, you have to get an air compressor, and inflate the system to 120 PSI before it will run. That's why it's got bicycle type fittings. I know it says it's rated for 150, but you never totally inflate them.

However, since I'm a HVAC professional, and you're a home owner I might not be totally honest with you.

Well, depending what metal joining compound he used, mighta not needed inert gas. I know I've not used inert gas for the stuff I use.

Yep, this fell is either trolling, or sincere but doesn't quite know what he's up against.

That would work!

If we lived on the planet Freon®!

Yep, the planet Freon, which is right next to Uranus?

I'll look into the wire question for you but I have to ask a few questions first.

Did you use solder or brazing rods to make the connections? Did you pull a vacuum before letting refrigerant loose into the system?

If not, you need a EPA certified tech. to do this (legally).

If you can remove the cover from the unit and photograph the wires and where they connect inside, you can get a better answer than a guess.
