@czechmate6916 nor mine. I used an old school flaring block forever. Navac had a sale on these last year and I didn't want to let it go. Glad I bought it as it's fantastic and makes perfect flares

@@jasonjohnsonHVAC If I was still in the game I definitely would get one. That is sweet. 💪💪

@@EverythingHVACR same to you bro.

@@Eddy63 happy 4th buddy

@subcoolHVAC Same to you and yours. Enjoy it safely. Back to work tomorrow for me...so it'll be a quiet day

Anywhere and everywhere is a work bench. Happy 4th

@@czechmate6916 getting older...getting wiser....body to broke down to use the knowledge...hahahaha

@@jasonjohnsonHVAC Yes sir. You know I miss doing what I did but I went back it would be like starting from the beginning. I think I’ve probably forgotten a lot of what I knew. Not to mention I really haven’t kept up with most of the new changes. At least I’ve got a few HVACR channels I can watch. Stay safe out there in this heat brother.

@subcoolHVAC I know huh....I was laughing too

@@wata_laf appreciate you

@HEFTYLEFTY303 totally agree. I know trane sells one. Don't have the part # to order it. The counter guys....are shall we say...less than helpful. Thanks for the comment

@bbasham46 my pleasure. Hopefully it helped a little

🫡🤜🤛

I don't know, they look old...but I really have no clue....I did find out it's been 8 years since they have had an HVAC company do real maintenance on them.

@@jasonjohnsonHVAC I don’t think we have any RTAA survivors left here, keep em going Jason 👍

I tried that on the controls and it didn't want to work. So I went to plan B.

Yup, when its that deep....sure do. Gives you a chance to check the total charge, though. Make sure to check your oil level as well...thats important for proper health and operation of the compressor. Check and test the oil DP switch, master oil solenoid....you might as well. Don't want to be called " it was running before you worked on it"

Just replace all refrigerant - live sensors at the same time if the machine is older. Just sell a one and done update on all the sensors. Especially if you are pulling the charge. Good time to replace relief valves too!

Ebay. $70...fairly inexpensive and its rated for 650 psi so it'll handle 410a

🫡🫡🫡. Appreciate the comment.

I was doing a vapor pull. I used the push pull and didn't record pulling the liquid out.

I was using just the Appion speedy wye. No gauges.

Great question...I agree 1000%. Seeks like Trane misses the boat on that with a lot of equipment....other than their low pressure centrifugals...which has an oil pump. Thanks for watching.

Appreciate you brother

😆😆😆. I like that analogy

I didn't mention that it has to be off. It was, but good point by you. It also has to sit for at least 10 minutes after being off before you take the sample too. Thanks for including that information I forgot to mention. Sometimes it's easy to forget to mention all the small details that are also important.

I'm curious as to the results myself. Looks like it was cooking a bit

🤘🤘🤘🤘...thanks brudda

Lol....that they do. The customer is concerned about the other ones and might be buying some spare coils to have on site. There are 2 of those RTU'S on the roof, each has 4 coils

Because I was getting so many errors, especially for weird stuff. The whole thing works on a comm bus. Every module is daisy chained together. The fact all the modules were showing alarms, gave me an indication that it was something on the comm bus.

It looks like he has his recovery cylinders out and is trying to recover liquid faster with the sub cooler

​@daniellundquest8252 that's exactly it. Faster recovery.....faster to get the repairs completed

That is what was recommended....unfortunately the salesman is still dragging his feet on sending the quote....doesn't matter though...I don't work for that company any longer.

Yup, that's my plan as well. Use chilled water if possible, condenser and or city water is a secondary method, either way is better than nothing at all

Yes, that is my plan, when available to use

I like RTAA's....built during a time when we didn't need to over complicate things. Simple machine that does it's job. Subcooler worked flawlessly.

@@jasonjohnsonHVAC totally agree

🤜🤛 it worked as hoped for.

I absolutely don't mind. I put it out there to share with others. Let's all rise to the top

I didn't check the water temps, I would feel it every once in awhile. The leaving felt about 15° warmer, but that's just a guess

@@jasonjohnsonHVAC that's good drop!

​@FroggieBeluga it worked great. It was 97° outside today and it didn't struggle at all. With the sun shining on the recovery tank

It’s essential kit for chiller recovery outdoors, especially on 410 scroll chillers in the summer. I don’t bother when doing repairs in the snow as it’s cold out already. Cheers bro. Sorry for spamming your comments, got bored after work. Haha😂

@@FrenchBeefCDNbro you know any helpful videos to learn these types of units , I’m in school for HVAC just trying to still get more better understanding as well

Completely agree.

Valve always goes on the leaving water side. That way the HX, coil or pump never has a chance to run dry. That is also where you control flow.

Appreciate the comment. I wanted to make sure it was not just a one trick pony. It's fairly cheap to build and it's kicking but. My refrigerant going into the bottle today is 92° and it's going into the subcooler at 117° sat temp.

I would love to get my hands on a decommissioned WSHP to do exactly what you said. I usually don't have the chance to replace any, so until then....this will do. Thanks for the comment

We had a bunch of warranty coaxial coils from heat pumps that were just sitting on a shelf for years… but you can buy a brand new one for about $150 at the supplier. Yours will work beautifully all the same, it doesn’t take much flow to cool the refrigerant down. Like a large coffee cup a minute is plenty of flow, any more is a waste of water. Sometimes when you have access to chilled water that is the best and no water gets wasted. You can recover about 1lb vapour every 60-90seconds (134a) using a standard 1hp air cooled recovery machine which takes about 120-180 sec without sub cooler.

That's your opinion and you are entitled to it

Wrong though. A contained heat exchanger is much more compact and efficient than a coil of copper in a bucket, unless you are flowing the water into the bucket constantly. The one at the supplier (cps) is only 1/4” tubing and requires a bucket of water which will warm up. Having a coaxial or brazed plate heat exchanger allows you to slowly feed cold tap water through the coil keeping your recovery discharge closer to 60f vs 90f bucket method. Much easier to run hoses from source to drain than drag a 5 gallon bucket let of water. I’ve done both methods, my back much prefers to carry empty hoses and a sub cooler than a full bucket of water. Plus you can make your own for cheap and just need to braze a few adapters. My coaxial coil cost less than $150 and took me an hour to make. Have used to recover thousands of lbs R134a, R410a on air cooled and water cooled chillers where a water cooled recovery machine was not available and frankly no longer necessary with my sub cooler. Tank stays below 70f even in the July heat.

@@FrenchBeefCDN If it worked so well everyone would have one already.

That’s some logic there. It keeps heat pressure down, which keeps flow rate up, doesn’t cycle hpco, doesn’t pop relief valves, stays cool the entire time and you don’t need to drag a 65lb bucket of water around. Cuts vapour recovery down in half which saves you the technician time standing around waiting on recovery. It is a good idea and the guys I work with started making their own after seeing mine in action. Large commercial recovery machines (York RP-2200) use a coaxial coil condenser and recover a pound of vapour pump in seconds, I just tried to mimic that in a smaller lightweight package that I could keep in my van on machines under 2000lb charge. It works, really well.

@@FrenchBeefCDN 🤘🤘🤘🤘🤜🤛

Thanks for the comment.

😆. Yeah made a nice subcooler for less than that CPS one. Real good heat transfer as well. The ancillary parts I had laying around. Only had to buy the hose. It works good and is decently service friendly. I like it. Thanks for the comment
