Hey man just stumbled across your videos. About to start my first day tomorrow as a supermarket tech. Completely green, just two semesters of hvac classes so these videos have been a god send. Thank you for the content I hope your channel blows up cause there is valuable information in these!
It's the first time I see loading 3 cylinder at once using the 3 1/4 hoses of the manifold and shooting with the 3/8 one. I take note of that! 🤟Love your videos man ❄🛠
Thanks I see that you've been watching quite a few of them I really appreciate your comments. It's really encouraging to see that they're helping people :)
Man, this brings back memories. The sound of those recips, the complex systems. Lucky for guys like this keeping watch over the systems that no one sees in the store! Back when I did this, there was just 12, 22, and 502...totally different now. was talking to the Kroger guys recently about CO2. I'm just an air conditioning guy close to retirement, but this was one interesting video!
I don't work on racks just what i'd call commercial....restaurants, hotels, litte supermarkets etc. Your're a fucking good engineer, what ever they pay you, it's not enough.
Have to put this one in the HVAC Hall of Fame playlist - it is loaded with nuances of an "advanced class" in HVAC... AND it's not presented in such a glossed-over way that if you understood what was being said, you wouldn't need to watch the video.
Great video - tons of nuances - but could use a diagram/segue at min 3:00 (re: getting a grip on flows and direction, before and after closing the valve)
In a deli case, I was going to record it but I ran out of battery. The straighter core was leaking by and the cap was not screwed on very tight. I could literally hear it whizzing out.
Know a guy that miss trouble shoot a unit and dump like 1000 pounds of gas in . Turned out a solenoid had failed. From what I understand it wasn't a fun conversation. I made sure I was no where around the office for a couple days!
@@gendronhvac-r1269 wouldn't have been that bad if he stopped after a 100 pounds but he keep going. Sight glass never showed anything. It happens to everyone at sometime.
so what was the leak? are there any monitoring devices in use on large volume systems like this to detect leaks before large volumes of ref might be lost?? or maybe operators monitor daily the levels somehow?
It was leaking from the deli service evaporator coil. That is a prime spot. All the meat juice just eroded the coil. And there is a leak detectoring system. But it is very bare bones we don't trust it. It will detect like large leaks but only In Certain areas alway best to pull out your Personnel leak detector and not relay on those. Hope that helps
I work on small systems compared to you. 25lbs max. When our customers have blowouts like that we charge them per pound for the gas. Do y’all do the same on 300lbs? Lol. 300 x whatever yalls lb rate is?
So back-in-the-day for my company it used to be contract. So it was part of the contract that we covered all the gas. The problem with this was the stores were taking advantage of this. Not reporting things until the last second. Refusing work and refusing to fund work that would prevent future leaks. So our company change the contract so they pay us back for all of the gas used plus a little extra I think for us getting it. Other customers we have they will store like 1,000 lb of gas on location for emergency and the store itself purchases and replenishes the gas as needed. Some we just charge per pound. Every customer kind of has their own unique scheme that they agree to. Hope that helps
Don't ever charge a system like this your feeding straight liquid to your compressors. Fine your biggest liquid line hook up to it and close that ball valve so your pumping down that system and sucking the refrigeratant from that jug of refer
You can do that If you like, But I have never meet a single refrigeration tec do this. Also Most compressors for supermarket refrigeration are rated to do this. But good luck man I hope the video help a little !
"DorahGAH thats how you do it" Words to live by. But seriously, loving the videos. Learning alot, much appreciated!

I'm glad there helping :)
Great info. I'm a retired supermarket guy of 45 years, enjoyed it sir!
Thanks :) and if you ever feel the need to comment some wisdom feel free !

Thanks for video New York or Boston? Super market guys are very knowledgeable!

You can also close off a couple systems at the liquid line and see if your high temps start to drop
Thank you for the comment absolutely true. :)
Awesome videos. Thanks. Quick random question, what ear phones did you use? Microphone sounds great
I'm just yelling at my phone 🤣
Another banger 💪💪
Where was your leak at ?
In a deli case,
I was going to record it but I ran out of battery. The straighter core was leaking by and the cap was not screwed on very tight. I could literally hear it whizzing out.
@@gendronhvac-r1269 Would be interesting to see a video on tracking down a leak in a situation like this.
@@lwilton
Sure next time I come across it.
@@lwilton not that interessting. search for oil and you got ur leak 99%
Know a guy that miss trouble shoot a unit and dump like 1000 pounds of gas in . Turned out a solenoid had failed. From what I understand it wasn't a fun conversation. I made sure I was no where around the office for a couple days!
Lol. 😂
Unfortunately things happen and from what I've seen a lot of it's because no company trains anybody anymore.

25 lbs. of 504 per cylinder.
25lbs pee 507 yes :)
