BACK IN THE LAB. MESSING AROUND WITH A TRANSFORMER,RECTIFIER, SCR, AND SOME HEAT STRIPS
Best part of this SC is that the water is continuous flow and therefore always cool from the spigot. The CPS SC will melt a bucket of ice quickly in the summer heat and when recovering a 125+lb VRF system you end up shagging buckets of ice and lug it up to a roof.
Hell yes! Subbed, love the chiller videos.

Install a 24 VAC LED ACROSS HP and LP switch leads. Done. When either pressure switch opens, the contactor de-energizes and the red or blue LED energizes.
@USA-GreedyMenOfNoIntegrity I could do that, was just using parts I had on hand. Appreciate the comment
Would have loved more if there was a close up
Thanks bro , please make more
@Craigtucker99Tucker-zx1yd appreciate the feedback and I will do better the next time
Nice addition of the F/A relay, 💡A steady diet of control work is good for the old thought processor 🤓
@subcoolHVAC yes sir...keep the mind sharp
Double J thank you for sharing your knowledge
@@hvac_audaz_firme thank you. Appreciate the feedback
I heard or read somewhere while back: give hvac service tech relay and transformer and he'll make earth spin backwards where sunrise will be on the west and sun set on the east. Don't remember who said that.. but this made me think of that😁 true
@FroggieBeluga getting all Socrates on me huh. 😆😆😆😆😆
Nice layout & good info ... Thx JJ
@Eddy63 appreciate you buddy
Get yourself a better meter. That uei is garbage. Fluke 87V is king for industrial and heavy commercial.
That garbage meter has lasted 7 years. I don't claim it's some nice piece of kit. I have plenty of Fluke meters....but who cares if it works ,it works. Not every person can afford all the nice tools....if they get the job done who cares.
Good Stuff JJ. Electrical is my week spot. It doesn't come second nature just yet. I can do it just fine but really have to think about. Thanks fir the vid.
@@jasonjohnsonHVAC not as accurate for critical and high impedance circuits. False readings. Have bench tested this meters when I used to have it and meter was always off. There’s cheap option fluke meters to so don’t play the not everyone can afford it all. I can tell you have been in the trade for awhile and was recommending the 87v. Can’t put a price on accurate readings especially in industrial applications
Well said bro
@@jasonjohnsonHVAC I have both. If you have the knowledge and skills, it doesn’t really matter whether it’s $100 meter or a $500 meter you can get the job done. We’re not building rockets. How much accuracy do we need?
Nice addition 👍⚡️🔌

I'm a Retired Industrial Electrician / Instrument Tech, worked inside refineries most of my career. I urge you to make the jump into the industrial world, you've outgrown commercial bud.
@nuxboxen I did a lot of industrial when I lived in Buffalo. I'm in Austin TX now and it's not that prevalent here. In Houston and Dallas and possibly San Antonio there is more, just not a ton here. I would love to do it more often. Appreciate the comment
You forgot .7😅

Cool trainer. If I had more room at my house i would do more stuff like this. Great video JJ

I love that flaring tool. We didn’t have that in my time. 👍👍
@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

I recently came across your channel in my feed and subscribed. I’m also in Tx. Retired a few years ago after being in this line of work for forty seven years. I used to make the same moans & groans when I would have find something to grab on to so I could get vertical again. 😆😂🤣 Have a safe July 4. 💪💪🇺🇸🇺🇸🙏✝️
@@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.
Nice job, Jason!

Thanks, great video
@bbasham46 my pleasure. Hopefully it helped a little
Great video brother.

😎Nice job there, have the condenser coils ever been replaced on those RTAA’s ?
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 👍
You could have put the circuit in Service Pumpdown mode instead of recovering all that gas. After it shuts off pump what’s left in the low side to the high side.
I tried that on the controls and it didn't want to work. So I went to plan B.
Could you show us how you would "MAG" the condenser...Thanks in advance
lol I have to do the suction and the discharge saturated sensors on an RTAA soon too. Too bad I have to recover the entire charge 🤦♂️
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!
Where did you manage to buy the sub cooler?!
Ebay. $70...fairly inexpensive and its rated for 650 psi so it'll handle 410a
Great Video Jason. I see you in alot of hvac video chats great to see you uploading your own. Thank you for showing us the recovery process in a refrigeration system. Keep em videos coming😅
🫡🫡🫡. Appreciate the comment.
You runnin both suction and liquid lines with gauges into a T then through your recovery machine and through the subcooler to the tanks?
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.
So why wouldn't they put a min and max level sight glass on the separator instead of having to do all that messing around with the hose and all that ? I don't get it .
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.
Good stuff, thanks, Jason!
Appreciate you brother
Yep, there’s something going on there… oil should look like Pee not Tea 🤣. Thanks for the video!
😆😆😆. I like that analogy
I’m not sure if your video mentioned this but you need the check the oil level in the off cycle of each circuit. According to Trane if the analysis comes back ok and your pressure differential across your filter is ok then they suggest you leave the oil alone. I guess you’ll have to see what the lab says about your darker sample. Great video! 👍
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.
Great video! Never seen that handy trick with the sight glass for oil level. Definitely curious how the test results come back for the dark one.
I'm curious as to the results myself. Looks like it was cooking a bit
