Six Very good slide show of how to correctly resolve the replacement of the header. I have never ran into this problem before, It's new to me. Thank you for the help.

No Problem.
I still run into local Technicians in town who struggle with this issue from time to time.
Most of the time they're trying to retro-fit with a TXV instead of going back with the factory part.
When I ask them why they're not going back with the factory header they usually tell me it's easier and cheaper to retro-fit a TXV into the unit but that's just not correct.
Replacing the factory header is a two hour job for a guy that's done it a couple of times and maybe a half a day for a tech who's doing his first one.
And it's a professional looking repair.
For the guys who like to retrofit a TXV into these units, how do you size the Nozzle orifice for the distributor ?
Are you buying a universal distributor assembly with a orifice or are you even using a nozzle ?
Because the last time I saw one of the TXV repairs it just had a bundle of 1/4 copper sweated straight into the discharge opening of the TXV with no nozzle assembly.
I had a similar problems with a York 5 ton. The owner told me that was running a little bit bad 3 weeks ago but the las 2 day it was not working. When I checked I was a leek in the ..Cap nozzle. With a TXV..
Like I know is difficult to brazing on it, probably get clogget. So I recycling the gas an put 5 psig of nitrogen to minimizing the carbon particles and change the dryer.... But when I charging I notice that 3 of the 8 cap gas no freezing with low charging when I done that caps was not working. Thinking that the silver clog it. I order a new cap. Nozzle.
The worse part.
When I come back to install it turn on the machine and the cap are working so good.. All of them.... I guess that was a peace of oil burnet that clogged it and the go away so. I pay 150 DLLs for the nozzler
Have u tried contacting Sporlan? All they gotta know is how many distributors tubes u have and what tonnage is your machine. They can tell you what size of distribution tubes to use and also give you a part number for a distributer and txv valve. The first one you do could be a PITA, but once you do it a couple times it gets easier.
It could be different now though. I haven't installed one of those headers in years. Sometimes it is just better going back with a header. Back then it was always a waiting game for Carrier, those headers were back ordered like crazy. That's why I began installing txv valves.

RTFM!!!
Guess we are going old school with this unit meaning I have to pull out coil and get access to all orifices and blow them out with nitrozen then sweat them back in . Good news its only 100 and not 103 degrees today! Then I have to replace a txv on a system that was replaced yesterday with a 410a condenser and the installer left the r-22 txv in place.
Old thread but good information. I remember seeing another thread about this. I think it was PHM that started it. Have not run into this yet.
You need to put the phone down and get back to work!
CMS/Nextech used to have a video on their website of an Acutrol to TX retrofit.
Those repairs can be a little trying, but nothing more satisfying than a challenging repair done right.
Anybody think that "A/C renew stuff" would help with this situation (restricted header) since it appeared to work with the gummy Copeland rust inhibitor fiasco?
