Carrier Fixed Orifice Header Replacement

[gravity]

they believe their factories are controlled environments and this allows them to use smaller driers.

i just found this info out the other day.

the first 2 numbers on the drier is the size of the drier and the last number is connection size.

ex;
163s = 16cu in and 3/8 sweat
164s = 16cu in 1/2" sweat
165s = 16cu in 5/8 sweat
607s = 60cu in 7/8 sweat

and so forth. never really paid attention until an ol' timer told me

Well.Tranes got some weird ones. Here's the tiny one! 1/2 inch in , 5/16 out. And it's actually a 034!! Clogged and almost took out a compressor!!!But, i guess they figure as long as it makes it through it's 1 year warranty. That's good enough!!!!

034 = 3CI

034 = 1/2" solder

034/2.5 = 5/16 solder

[gravity]

yea i hate those little ones.

Thanks for sharing!! I never knew that either!!!But, i do now!!

i just did this on a small 4 ton carrier rtu. mine came with stubs that go into the coil then the header goes into the stubs.

what a PITA it was. had no room to work and panels couldn't come off to make more room. i got it done and holding pressure

over night at 155psi. it was quitting time. will be back there at 7am to check pressure test and vacuum it down.

wish i had the header you got to replace. alot more room to work on yours. think my unit was 48tjd004 its from 1995

Yea they all come with the stubbs. At least the Carrier replacement headers do. I don't use the stubs, the seem redundant and extend the header.

I just toss them in one of my truck compartments and use them as street couplings. I've done 6 total in almost twenty years. A couple more after this repair. To be honest I think they're easier to replace than going back with a TXV retro kit.

With that said too many TXVs are scrapped do to tech incompetence and they do seem to be more rugged than these fixed orifice headers.

But the retro kits are ridiculously expensive. It's hard to convince a customer from one metering device to another when the difference in Price is so exorbitant.

I should get the numbers off the unit, it seems crazy that our supplier would quote the whole coil rather than manifold.

If you ever wanna try retro-fitting a carrier RTU with a TXV. All you gotta do is contact Sporlan with the size of your distributor tubes and how many you have...they will tell you exactly what you need and give you all the part numbers so you can order it from your local Sporlan Rep. I found this to be less time consuming then trying to wait on Carrier just so they can tell you the header is on back order. Ive been doing these retro fits for a while now and no problems as of yet.

KB Cool - I usually go through ARS Tempe to order these parts there usually pretty good about ordering from sporlan..... just a heads up if you ever wanna try it.

Good stuff here guys. There is one problem unit we have that other people have put multiple compressors in that need just this done to it. Good work six. You look too young to be doing this stuff that long?!?

[pyramidhvacr]

you can make one your self 3/16 copper. Or 1/8 in I used 3/16in. Piston holder from old coil 4 or 6 feeder remove them 3 in. 7/8 copper. 24 in on each 3/16 feeder . Cut out header. Add a 1 piston at btu. recharge. Do not need a TXV. , The mfg 5 ton hole is .028 in each all Have trash in each. Txv better on refrigeration not A/C.

[gravity]

i would disagree about the TXV comment. Good job though.

[manny238]

good job pyramidhvac. i personally like converting to txv valves. havent had any problems or callbacks.

[Joehvac25]

I guess our unit won't be needing any work its getting replaced
