Speedaire 2z499b compressor 230 or 120 converted

[slash5]

I recently bought a speedaire compressor model 2z499b.
The motor model is a 3z419f
The previous owner said he had it converted from a 230v to 120v so he could plug it into he 20amp socket.

The plug on the end of the cord will only fit a 20amp socket.

He said that he had an electrician do the work for him. I want to know how to convert it back to a 230v compressor because I have a window AC unit that is running off a 240v breaker (two 20amp breakers).

I'd like to be able to unplug the Air Conditioner unit and plug the compressor into the same socket.

I'm afraid I will damage the unit if I try and do this before I convert the unit back to 230v. I'm not sure what the electrician did. He may have just put a different plug on the cord.

Another question, since the AC unit has two 20amp breakers, is this considered a 40amp circuit?

Also, does anyone know what type of oil I should put in the compressor? I don't know when the last time it was changed but I'd like to change it before I get it running. I found this site after google found this link

Thanks for any help.

Ok, I found out some more info. The motor is a lr22132. It says 120/230 on the side so it can be configured for either. There is an access panel on the side of the motor where I can move the lead around. There is also a diagram on the motor that shows how it's supposed to look when set up as 120 and 230. They use letters that say T1, T2, L1, L2
I'm not sure where these letters mean but from looking at the diagram, the motor looks like it's set up as a 230v motor. They guy that sold it to me said it was a 230 but he had it changed to a 120.

Will I fry the motor if it's set up as a 120 and I plug it into a 230 socket?

Also, is there a way to upload pictures to this site? I'd like to take a few snap shots to show the readers. This is probably a no-brainer for most of you.
Thx.

You should find labels on the motor leads (wires) that correspond to the letters (T1, T2, etc...) on the diagram. Connect the leads together as shown in the diagram with wire nuts.

As for the receptacle, it sounds like the breaker setup is not correct for the 220V, the breaker should be one unit, that uses two slots in the panel or at least have the handles on the two breakers tied together with a clip so that if one breaker trips, the other one trips as well so that all power is removed from the circuit. Note, that you may not be able to use the clips with all types of breakers. With 20A breakers, it would be a 20A circuit at 220V. Also note, that the breaker should be sized to protect the wiring, so there is probably only 12 gauge wiring on this circuit. The motor nameplate should also list the amount of amps that it will pull under full load (sometimes abbreviated as FLA).
