awesome video as usual. im in hvac/r trade school right now and it wasnt until sometime last year after coming across your channel that i realized how interested i was in the refrigeration side of the business. i was originally a heating and air helper going to school to do the same thing but ive actually been focusing more on the "R" side of things after being exposed to it through you
It's funny, the (now 80 year old) technician that taught me, watched this video with me and said "There was a couple of decades or more that I never once used a drop of nitrogen. The little bit of carbon created doesn't hurt a thing. Some of it ends up trapped in the oil, the rest will end up in the filter, and anything that is small enough to get by it sure won't be hurting anything. Most of the systems that I serviced and installed 30 years ago are running today with the majority of the ones that are not are due to deteriorated coils and similar wear out issues, or just replaced to upgrade to higher efficiency. SuperTech: Don't sweat the sweating..Just do a good job using an appropriately sized torch, which seems to be your M.O anyway. I did a couple of hard pipe-10' lengths- that were over 150', lots of brazing on those, all in inch and a half copper! No nitro, but did actually vacuum it out with my shop vac before final connection at each end, just to be sure!" Ah the interesting stories this guy has, lemme tell you. He's done some really large supermarkets, hi-rises, and warehouses, where we all know that for $100 worth of nitrogen to purge lines of a million dollar system seems like a no brainer, right? Definitely makes for clear oil opposed to grey oil. I know I have personally done a couple compressor changes without a nitro, never had any trouble...At I least admit it!! LOL! In my book, you never lost the 'badge' in the first place!
I don't know if you can get it back yet... that part where the micron gauge was at 106,,,, sure sounded like it was connected to the vacuum pump end of the system. should pull the vacuum through the entire system with gauge at the furthest end. just what i was taught. good video though..
We all get in a hurry and make mistakes. It what we do after them. To correct the problem If the equipment works after you leave. That's all that matters. Good job. Have a blessed day
Lol. not a Big deal. we all forget stuff. thats life. Just proves your human and not a robot. i'm sure the people before u didn't purge with nitro. That Condensing unit looks like it's been toasted a bit before u got there. sight glass is kinda nasty looking. thats the least of your worry's. you blew it out and the little residual will just go into the drier. that's what driers are for. Good Vid.
Hey Dave , top job.... i've been in this industry since 1984, i've come to the conclusion... weld it all up, put in a suction filter drier at comp... quicker, easier, less mucking around than nitrogen,, clean compressor at the end.. that's the goal..
Hey Dave, yeah, you messed up with the multiple braze joints with no nitrogen purge. Easy fix if you have the time is to braze in a 1/4” schraeder to the inlet of the liquid line, and a reducer from your suction line to 1/4” schraeder, run it through your recovery machine for two hours and wash that stuff out of the system with refrigerant. Make sure you have a LARGE 1/4” or 3/8” drier before it goes through your recovery machine, say a C-163 or a C-414 or so and clean that system up. The only other cure is to keep an oversized drier in the system full time until it clogs up, I’d go with the first method. In any case, you’ll need to monitor the inlet screen of the TXV and if it is getting clogged up. Bad situation all around I’d say. At least you know what you did so you can correct it in the future if problems occur. I don’t personally nitrogen purge on a two to four braze point job, but over that I have to nitrogen purge, or I’ll have problems. At least you noticed your mistake and can correct it if it causes problems in the future. Thanks for showing us your mistakes as well as the more numerous jobs you’ve done without such mistakes. Good on ya!
Nice job, Dave. I have the same flow indicator you were using, and man does it save on nitrogen when purging the lines while brazing. Going to have to get that Sporlan magnet, pretty useful for situations like that. Thanks for posting. -Tom
I have the VN500 for nitro. I had one a week ago where I got halfway done and realized I set it on braze but never opened the tank. I didn't even get a super tech card and now I'm on the waiting list for a long while.
+Nor-Cal Refrigeration & H.V.A.C it's awesome. It can literally use the last drop of nitrogen from a bottle. I've used it for the past year and I wouldn't change. Definitely worth it.
I saw a video before, similar to this, and the tech found a red pipe plug between the service valve and the compressor that had likely run for years... were you thinking of that? I had two friends braze a pipe in the system. I think it depends how bad the plug was I guess...
What does that oil trap prevent? And what is it called when the suction line is sweating back to the compressor like that? If you don't mind schooling me real quick haha
purging slips everyone's mind from time to time. you are still a super tech in my book. the temp control you used, does it have an intigrated time clock aswell? thanks for posting.
It's dose not, that would be perfect. It only has on delay I set it for 3 min. The on delay can go up to 15 min. It delays after a call for cooling each time.
Drill holes with long drill bit( aircraft ) bit. I used a 1/4" on this one. 1/4 x7" hex head bolts, I usually will use 3/8" x 7" but the hardware store was out.
+Nor-Cal Refrigeration & H.V.A.C hang the 2 back ones first, slide the coil into those I use a milk crate on my ladder to hold up the front then attach the front 2.
Could you use a line set flush to clean out the line? Is it necessary to have the trap because the condenser is up on the roof? I don't do refrigeration so I just guessing. I know that with ac if there is a more than a certain amount of height difference the manufacturer want a trap in the line set.
Nice work, hope that controller will last in that envoirement. Why did you put a oil bend in there? Just bend the pipe a with a kink in it like 10 degrees down and the bend 100degrees up it will save you money and time (no welding). Keep up the good work, love to watch your videos.
At 3:11-3:12 you can also see your brazing rod didnt flow all the way in. Maybe add a little bit more next time. Just my opinion of course, i indeed have not had a striker for 15 years so you are in to it more than myself. Other than that little detail and no purge, you my friend "Rock"!!

Kenny Baker thanks Kenny.
The super tech badge is for life. You just got a write up, on a piece of paper that has been thrown out.

You are still my favorite Super Tech Osbourne! great braze my man, all you proved was you were human. Your videos always rock!
Thanks Albert. ? Have you tried using the tightness test with the smart probes yet.
Nice coil replacement. We all forget to purge sometimes. Not a huge deal for a couple of joints. That compressor will be a lot happier now.
This was a great video Dave. Make more walk in install videos
You got it Bro. Nice recovery.🍻
Fantastic job and nice braze joints too.
Thanks
Another wonderful job I hope more techs follow you.
Good video Dave.
excellent job partner!!!! looks smooth like strawberry ice cream!!!!

Nice one, Dave. You totally redeemed yourself. Great work.
Thanks.
Great job, super tech. I never lost confidence.
Thanks man.
Another good one. You get your badge back.
Right on! Woohoo.
We don't need no stinkin' safety glasses !
Pretty welds, good job.
You do great work
Great job Dave.your the super tech.
No. I’m goofy and I know it. Lol
Lol
gracias por compartir , thanks for sharing ✌👍👍
Cool video, thank you for posting it!
Thanks for watching

Great job Dave
Thanks harry
shoulda showed yourself covering the open end of that pipe as you slid the insulation on over it!

doing a good job, I like it.

Nice work buddy , we all forget from time to time lol
Man I've been on role lately. Lol
Good video. Very nice work.
Thank you.
At least You remembered before it was too late.Great job
Thanks.
wow thats a neat job!! nice

Thanks Tom.
Thanks
great videos man, I don't work in this field yet but I'm curious as to why its necessary to have a pea trap?
Sal C for oil return.
I have the VN500 for nitro. I had one a week ago where I got halfway done and realized I set it on braze but never opened the tank. I didn't even get a super tech card and now I'm on the waiting list for a long while.
How do you like vn500?
+Nor-Cal Refrigeration & H.V.A.C it's awesome. It can literally use the last drop of nitrogen from a bottle. I've used it for the past year and I wouldn't change. Definitely worth it.
+The Joy Of Piping I have to check one out.
as soon as you started welding that without nitrogen was a SMH moment
Glenn Sepelak I was stone cold busted😂
Checking out the alpha install 7 yrs prior to the omega patch job.
Acidic product? Or just reality of planned obsolescence?
Perfect use of nitrogen🙀
great video. on 404a what evap pressures are you looking for? is 40-50 psi a good start?
Eddie Sellers depends on box temp. 20 degree evap for a medium temp box.
I saw a video before, similar to this, and the tech found a red pipe plug between the service valve and the compressor that had likely run for years... were you thinking of that? I had two friends braze a pipe in the system. I think it depends how bad the plug was I guess...

It's dose not, that would be perfect. It only has on delay I set it for 3 min. The on delay can go up to 15 min. It delays after a call for cooling each time.
where did you get that striker? can you still buy them ? it's cool
Rsd, I don't know.
Nice work! Like you I think the "clean" pipe was probably as dirty as the no purge braze areas lol. How did you attach the coil to the box ceiling?
Drill holes with long drill bit( aircraft ) bit. I used a 1/4" on this one. 1/4 x7" hex head bolts, I usually will use 3/8" x 7" but the hardware store was out.
+Nor-Cal Refrigeration & H.V.A.C hang the 2 back ones first, slide the coil into those I use a milk crate on my ladder to hold up the front then attach the front 2.
Thanks man. I guess you can get to the top to put washers and nuts on?
+ComfortPlus Heating and Cooling that part was a real son of a gun, lol no video because of all my foul language. Lol
Dave, super tech badge pulled for no nitro purge. I just heard the d word from your mouth. Bad day. Let it slide, keep up then great field work👍
I have a punch of questions. Why the p-trap on the liquid line? How was the Balance Point derived? I’m sure there’s more for now
GOOD JOB ,DID U SEAL THE COPPER BEFORE U PUT ON THE ARMOFLEX ?
Not sure I understand your question.
no worries we wont take your badge unless you become a multiple offender sir! thats what the filter drier is for anyways lol
Totally redeemed yourself!

I know that with ac if there is a more than a certain amount of height difference the manufacturer want a trap in the line set.
Trap for oil return. I've never used flush, just nitrogen.
Nor-Cal I been building US Embassies overseas. Can I come to Santa Cruz and run SC's with you for a couple weeks to get back up to speed?
You might be able to apply for a waver on that Badge.
Filling out paper work now.
Hi, what solder are you using, do you use flux, one last question what make model size tip do you use? Thank you
Jorge Nunez I use 15% no flux and 56% on copper to brass with flux. I’ve been using a mini rose bud tip
you have to post a few more videos now to get the badge back : )
so you didnt have to adjust the txv? piping well done.
I need to go back and check SH at set point. It was at 10 with a 48 degree box.
if you dont mind me asking are you a one man show? if so how do you like it/is it worth it
Yes and sometimes
X11 will work in that situation
Nice work, hope that controller will last in that envoirement. Why did you put a oil bend in there? Just bend the pipe a with a kink in it like 10 degrees down and the bend 100degrees up it will save you money and time (no welding). Keep up the good work, love to watch your videos.
I know you forgot on purpose to teach us worms. What does that sporlan magnet do?
Andy Galindo opens the solenoid
you use flux?
Not with the 15%. With the 56% I do.
+Nor-Cal Refrigeration & H.V.A.C jim p. is a flux guy all around, so i started using flux on everything
why did he lose the badge???
He didn't purge with nitrogen when he brazed the trap on the ladder.
+Jonathan, Ken Leonard and Sons HVAC yep I chocked that one. Totally got ahead of myself.
Dont they pooh in the streets in Cali?
Yes and they get free needles and leave them everywhere. No BS.
@@NorCal-refrigeration That sounds terrible
Chad Tinsley yep

At 3:11-3:12 you can also see your brazing rod didnt flow all the way in. Maybe add a little bit more next time. Just my opinion of course, i indeed have not had a striker for 15 years so you are in to it more than myself. Other than that little detail and no purge, you my friend "Rock"!!
Forget that nonsense! Nobody is better than you dude! Especially admitting mistakes. Brad Pitt envies you!
What is wrong with the sweat? Everything sweats in the summer where I live...
Lol
Seriously though, what was the sweat telling you?
+toolman so that compressor ended up being low capacity and I installed a new condensing unit. Scroll.
