I have a feeling this grocery store has got a leak. So we're gonna calibrate outside here and see if we can find something. I just got looking at the history there and it looks like one case, two cases that we're getting warm appears that, you know, maybe it froze up, but they just unloaded it so we'll just wait till Monday. Well, another case is going down too. So let's go take a look and see what's going on. All right, got nothing in the store. We're gonna go to PPM because I got a little hit since I opened up the door. We're getting out in the middle of the room. See how I got higher? Let's put the bag down. You can see we got all kinds of nasty crap everywhere. See if we can get in there and look at it. The store just finally got updated at E2, 3, 3, whatever. It's the online interface. I thought we had a leak, just wasn't in the right spot. But if it's back here, that's gonna be a nice easy fix. See if we've got our 12-door freezer's warm and our dairy is warm. What's happened is those are the first two places that have gotten starved of refrigerant. That's kind of usually how it goes with these racks. Usually they'll start going down in sections a lot of times from what I've seen. You can see how this came out and when it did that, that rubbed right into it. As soon as I move it, I can feel it hitting my hand or I could a minute ago. So we're gonna need to shut this puppy down. That's on the discharge side. So we're gonna have to shut it down first. We'll isolate all the discharge valves up on top and we'll isolate it here. That will allow us to re-braise that shut and then we should be good. You can see that's why we lost so much oil because it's coming right out of the compressor before it even hits the oil separator. So we run these really low, like 10, 20% on average. We don't put anything extra in there for this very reason. That way, if there's a leak, it doesn't run very long before it starts having problems. Now we can go through here and actually shut down the compressors, one, one, boom, boom, boom, which I'll probably put it in more alarms, but whatever. So here, I'm just gonna isolate suction takeoffs like that there that can leak back through. That's the kind of thing, man, it makes it difficult. It might be better off just to do the whole thing, but isolated there. Oil level, that's nice and low now, that's great. Smooth jaws, they're not channel locks. We're gonna go ahead and go through here. You guys know how to close a valve, so I'm not gonna record that. So we're gonna go through discharge closed, which that'll isolate us. So for the most part, we have four valves to close. So we'll get these all cranked in, and then we can go ahead and start our repair. Everything's in a positive pressure, so we don't have to really pull no vacuums or anything like that, but we can if we want. Repair, like I said, is gonna be right there, right through. I think you're gonna, yeah, it's gonna be pretty easy. See, I've had this happen once before, I had another score, so it does happen, unfortunately. Here's why you don't use a cotton pick and crescent wrench on this. See how it's not turning anything? Some jackass decided to round it off because he was too lazy to get his frickin' refrigeration wrench out. So that one's screwed now. We're gonna have to get on there with channel locks or whatever and frickin' crank it in, some idiot. Didn't get out his wrench. Get our long quarter inch hose, we can refill it. I just got my new torch handle, which is kinda nice. I've had rosebud tips for a long time that I can't use, cause I have a Victor torch set, but I just finally got me a uni-weld handle. So now I've got a rosebud that I can do up to two and a three quarters, I think, with this one, and I have another one that'll do up to six inch. And still be able to run it with a little set like that. So talk to the manager, gonna get a little kitty litter. We'll use that to get rid of the oil, which he's gonna just take that out of inventory. So we got that there waiting for us. Gotta get some oil, which comes with every bit of that. Definitely gotta watch oxygen levels in the room. The fan is on. I can feel, I feel lightheaded already. So we gotta watch that, you don't wanna to pleat your oxygen to the point where it ends up making you sick or dead. A little bit of big blue. Not sure if old Joe Sheer watches these ones or not, but Joe, there's your gauges, man. Setting there when I need them for the higher pressures and I got my old beaters here. There we go. What originally happened is we had to unload this one and this one right here. But then when the other one went down, that's when we knew we had issues. This weather's been swinging whole to hot, so it's hard to watch trends to really see head go up and down, stuff like that, because it's just really hard to tell. There's some more refrigerant. Have to find out which one it is, hopefully it's the one I got the most of. And our compressor room is conveniently located right up here and over there. So we got the cat litter spread out so we can work without being in the oil and tracking that throughout the store. Good there on that. We just got our bracket out. You can see where it's been vibrating for a while. I got to try and tromping out a piece of copper and putting that back in. That's mainly just in this one spot right here and right, a little skim code across the top. We should be fine. I got to clean that up with my wire brush. Here's where it finally ate through. That little pinhole on the discharge took this whole rack down. Now if they had refrigerant arms in here, they might have caught that. Now what I did do is turn the exhaust fan on, which the exhaust fan just ran on a generic little thermostat over there on the wall. So we're pulling nice fresh air in here to help airing this out. Everything stopped leaking. I don't feel anything coming out so we should be good there on that. Don't know if we got a port that we could actually pull on it or not. Honestly, oxygen is not getting in there very easily. System is big, the real world. We can go ahead and lie to you and tell you everything gets done exactly a certain way, but it just don't happen. Yeah, there's no isolation ports on this side to do that on. All right, we're gonna see if we can get that in in a little bit, but we got majority of it right there. All right, so what I'm gonna do is get a little stem there. I'm gonna drill the copper, put that on there, and then that'll give us a place to relieve the little bit of pressure that's still in the pipe. As you can see, to couple that would be very, very difficult. Well, wouldn't be very, very difficult. Here we go, got that. Got this little gizmo for my impact. Makes it a little easier. Here's the brush wheel. Got it cleaned up, go ahead and drill this out, and then we'll graze that piece back in there. This will give us a relief. So see all those ships that you see? They're still not, they're still not through yet. There we go. That'll fit right in there like that. We'll go ahead and leave that out until we're done. Gonna get that up one more time. Build that up, go to bridge on it. For the most part, we got this completely sealed. I don't wanna make sure I don't have any other spots that may have been kicking back out at me when I'm just walking it right along like you're welding with a regular jig welder or one here at the pipe. People may disagree with that, but. So on this piece here, I like to put it about a quarter of an inch in maybe. That way, when the alloy flows in there, I not only have built a bridge around the top here, but also have it pull down into the bottom. We'll just put our heat mainly on our big pipe and add a little bit at the top and work our way around there. So I literally got my phone hanging on my porch. That thing's awesome. And that's my smaller one. Then I got the Captain Hook. I have all these cool heads that I've been trying to use with my Victor Torch handle. I sent them back to Uniwell and said, hey, these don't work. They're supposed to work with it. Oh yeah, they work with it. Guess what, they don't. I was getting backfire and everything with that thing. I'm not getting none of that no more. There really was no good way other than to cut it back air and then do it in. Or unbraise it here and then you're dealing with all that. You gotta remember guys, it's frozen rack, so I ain't got all day to stir around. Luckily it ain't a bunch down, but it's Sunday and I wanna get this thing done. Just gotta finish cleaning some of this crap out that we got in there. Got a little bit of refrigeration through. We'll leak check real quick, make sure that's holding. So that right there, 132 pounds of pressure. All that back off. Yeah, see how that cat litter's working perfect. Keepin' that crap out of here, off your shoes. We built that up to the same height. See nothing leaking there on that either. All my valves here are still open. I gotta open all my suctions. And then we start recharging this and we gotta add some oil to this thing too. Gotta make dang sure we open up that hot gas again. That's some pressure. There you go. You guys have no idea how excited I am about that stupid torch head working like it should. Huh, I mean it's so stupid that, whoo. That's just not even something you really would think's that big of a deal, but I literally have had that head for two years, maybe four years, I don't know. I tried using it several times and it just would not, would not work. We got one last one here. It's awesome with these pliers, even though that's backwards, it has the strength to do it because it has such down pressure. See, somebody else did the same thing I did here on that one there, because they must have to do a relief in between there, or actually so you can pressure check, actually got pressure ports up there on top too. This is your three-wave valve. So you got normal condenser, reheat and renormal condenser. So for winter time, you need to get preheat out of it. Got my oil levels in my cans. Can't see on any of them except for that one. It looks like it ain't too bad. Hard to tell. We're gonna pump some into this thing though, maybe half a gallon. And then we can turn the compressors back on. So we got one little compressor on, easy 50 there. We should be able to also come over here to the home screen, see what refrigerant we got. 507, all these are, except for maybe that one there. Nope, it's 50 also. 407F, I know. All right, on mine here, I actually have an O-ring in there from one of my ice cream things. Literally screws right on there. And we'll charge liquid. Probably ended up taking, I bet you two of those at least. Now I've got a ball valve on mine. So I think it's either a 50 or 100 foot, 75 foot, I forget what it is. Now I wound this in a certain way that this should unwind straight with no kinks. An over-under approach, which is something you do with your electrical cords. And as you can see, it just drags right out, no problem. Now we'll go ahead and bleed her out. And then we'll do it good to go. Okay, good deal. Only place to tie on this for the suction side. It's right there by the sort valve. I don't see anything other than right here that we could go. If not, we could always go to that one down there. Never fails, you'll lose those little guys. Oh, it just goes all the way over and across. A lot easier than trying to carry that thing up here. Gonna add some oil yet to this thing. I just wanna get it back into the reservoir there. Just put her line out here. So just this half a gallon in there. I know what's on the floor didn't help it none, did I have it. And then we'll probably call it good. That one there is empty. On goes the next one. It was a fair, I had a little bit of a braze overrun. So I had to trim a little bit of that off. Didn't think about that when I was doing it. But not a big deal. Got the new clamp in there. Got it squeezed on top and bottom so everything's equal. There's no vibration now at all. Those are rated for 190 degrees and on average, you know, that's about the ballpark where it's at. But we have no vibration, really nothing major anyhow there. I'm gonna go ahead and maybe tighten up some of those. This one over here, they've already taken it off. So it must have been something wrong there, but they're clamped right here on the side of that. We're at 10% right now. Our temperatures have all started to come down finally. Our top one there is the one that was the warmest and it's already at 14. So we go in there and take a peek-a-poo. We got 21, 8, and 12. So those are the three sensors inside that case. And so far so good. You can see other easier ways to go in to look at your log, that you're dropping. Use your page down, really starting getting bad. Now like I said last night, manager said, hey, I already pulled the case. Just need you to shut the alarm off. Went ahead and set it to a higher. He didn't have no food in there. He said, well, I'm only gonna set it so high. I only set it at 40. Normally it's at 20. And it ended up going higher and higher. Well, that's why I did it. So it triggered alarm again and that's when we knew something wasn't right. Couldn't tell remotely how much refrigerant's in there. They don't have that sensor on here. This is an old control system that was, actually not even control. I forget who with the Kaiser Warren old fashioned thing there. I mean, some of these stores that got are just really antiquated. So this stuff here was just redone in the last year or two. And we just don't have, you know, all the goodies on it. Oil levels up. I had it all the way up to the top bowl. It's already dropped some. So it's already equalized things out a little bit. Out in there, I can see bubbles a little bit in there. So it's got oil. All these cyclasses are really dirty. Hard to tell on that one. It's got it in that one there. That one's got four bananas, what it kind of reminds you of. All the rest of them, we're gonna take a look at those, make sure they're okay. See, if it wasn't for the digital one there, you wouldn't even know what was in it. That one's next to nothing. That's 407 out. That don't show anything. But it's hot gas defrost. Three clean lockouts on. Look at our circuits. Dirty hands, clean money. So like I said, we don't get too crazy on how much we keep in it. All right, so I shut these two compressors down so I could go over it again. Just to make certain I don't have any leaks that I may have missed with the bubbles or since I put it together. We are good to go there. Nothing on any of that. Check all my fittings that I did. Going back over, making certain I don't have anything else. They would have been covered up by that last leak. Nothing worse than being out here since it might come back the next day that you missed something. Another rack down here is to make sure that nothing up here is easy. We can get while we're here, wrap this thing up. Oh, cut this one in. All right guys, look at this one. I'm gonna record that. Kind of looking at the rest of these here. Make sure they're okay. Look at that one there. Very similar, that's not mine. All right, hopefully you guys enjoyed the video. I know a lot of you don't really like the bigger stuff like this because you don't get to see it very often but for me, I always enjoyed it and it's something that I kind of enjoyed doing.
