    I sent you this bulletin via email and one that does approve 407C for some limited IntelliPak compressors that I found.
    Thank you!!! I will read it tonight. I always like to educate myself further.

    A friend in another company had to replace a 3D scroll 3x in 2 weeks. Lol
    No lie. I am not inventing this. They finally refilled with r22 with new compressor and it ran fine.

    So ever since those situations I was afraid to use anything else with those Trane compressors.

    I have a couple big units that show low super heat converted to r453a, i havent made a thread because i havent done my appropriate home work.


    It makes sense in hind sight as the pressure is about 10psi less. At a given temp relation:

    I couldn’t find Trane’s bulletin, but here’s a description of the issue. I believe Trane will void the warranty if any conversion is done on an R22 3D scroll.

    Can you not adjust the txv? If no txv, then remove charge.

    how does the oil stay mixed ? Does it have a steel ball inside like a paint can, and you shake it for 1 minute ?

    I run across it once in awhile, don't think I saved anything to my files. In fact, ironically, in your post you say the same thing I stated, LOL.

    Please note that while R407C is a viable alternative and exhibits close to R-22 performance, it requires a complete oil change to POE and therefore is not considered a “drop in” alternative to R-22.


    If you have a newer one, can you email it to me - Thanks.
    If you were a real tech, you'd solder a relay on that board and call it good to go.

    I do a triple evac with nitro to remove non condensables.
