Trane Voyager RTU

Does anybody know what that port is for in the pic. No gas left in the compressor. When I run the compressor for a few seconds then shut it off you can hear and feel air coming out of it. I have call Trane tech support but no call back yet. I think that is where all the gas went. What is that some kind of safety release? This is just a pic I found on the net with a good shot of the port. Thanks, jmb

Oil equalizer line between compressors when multiple compressors in circuit.

Should be able to seal that back up and the compressor should be ok? I did not see any oil come out of it at all. Thanks, jmb

JUST, WOW
When the rubber plug blew out, R-22 and oil had to have been chasing it!

referteacher is correct; this is an oil equalizer port. This port should have a copper cap brazed on it if this compresor is the only one in the circuit.
Better check your oil level after you fix everything

Not trying to be a smart ass but in the box the compressor came in is a set of instructions in a ziplock bag and a copper cap to seal off the equalizer line if you dont need it.I strongly suggest you read them.dont forget the oil45 before you start it up.

I just put a stub in it and pinched that off........................

I just put in a 9 ton comp on an I-pac with the equalizer line between the tandems on stage two. Had to prop the back of the comp up so that the oil would not be an issue while brazing. Those fittings are steel, and the instructions called for brazing alloy which is cadmium free. Hadn't thought of it before--Does that have to do with going copper-to-steel?

Another thing I will keep in mind if I ever need to replace the compressor with sight glass versus the one with the equalizer line adapter. I was replacing the compressor sight-unseen, so I was rather nervous about what I might find. It worked out okay.
Oh yeah, and since I didn't valve off the rest of the system, it was a GOOD thing that I didn't assume that the liquid line coming from the same side of the unit as the replaced comp was on was the correct liquid line. Because it was the other liquid line. Just another pop quiz. Yee-ha!

LOL-Jimbob, that was a good one!

Just a thought, if the trane compressor is not in warrenty you can get a much
cheaper drop-in replacement from Maneurop.

[controldude]

I agree you can get a Cheap Compressor

[esdd]

It gets kinda' convoluted but the trand 3-D scroll and the Maneurop compressor are the same, they come off the same assembly line. Danfoss originally developed and licensed the 3-D Scroll for Trane with the ability to sell as maneurop after the original patent expired. You now find this compressos in Carrier equipment with the Danfoss label on it, as well as in Aaon equipment with all three labels, trane, danfoss, and maneurop. I may be mistaken but I believe the factory may be in either Georgia or South Carolina.
