 walk-in cooler here that is leaking. I was here a little while back and we found the leak. I think it was right up in here in this area. So we're gonna take this thing out. I've not seen too many of these so I thought I'd show you guys what it's involved. It's kind of a nice design the way they did it because you're gonna be able to pull it right off the back. I'm gonna pull some screws out from the front side. Pressure and stuff's down here, screws here, three screws there. Alright, there we go. Now we can get into it a little better. Sorta. Still got the screws back in there which we probably just go through the fan blade here because it might be a little easier. Go left to right and up and down. Definitely got front to back. So there is the screws right there and you may have to take out the ones on the right-hand side there. Yep, we're going to take out the whole panel there on the left and have there on the screws. Let's take a look at the new one. Alright, now like an unboxing video, huh? Comes with that panel right there. So yep, we just unscrew that and that's nice. Quality's job won. Sell it out. Sell it out baby, sell it out. Looks like she's coming right out of there. Just gonna put a few things here. Nothing a 5-16's wall fix. Fill it over to here. Brings it here and there. And it should pull right out. We're gonna add a sight glass and a new filter dryer there. We're gonna put it in flare style so we don't have to fool with that as much anymore. This charge is completely gone hence the whole reason why I'm replacing the evaporator. So we don't have anything to recover. It's already gone. Now that they've brazed on that may not be able to flare it very easily. We kind of goobered it up a little bit. May have to do a little modification to that. First of all that out. This way there's nothing in here but good old clean nitrogen. What we were doing, nitrogen's coming in this side first. Obviously we wanted to do the last one coming out last, first and then that one there. So you can tell that it's probably been brazed on before. You can see crap inside there which that filter dryer has been replaced. Who knows. In case you think I got it overheated, I can put my hand on there so it's not that hot. Get on and get off. Looks like we might have to add a little piece there. That makes me wonder. Let's bolt this into place. We got the blade back into position. I wonder if this is there. They did have it set out here a lot further before. I think it's a little better there. So we'll have to check that and see how it does when we get down. Alright, so we got that replaced and we got that one replaced. So we're going to go there right now. I'm going to get our bulb hooked back up. Get the dryer out of there and then start evacuating. This isn't a normal flare tool. That works. That's how you get the perfect flare. So that's how you do a good flare. If it's good enough for 410A, it's going to be fine for 404. Like I said, that piece that was in there before was a total wreck. So we're going to go ahead and brace that up there and then this will just make it easier for maintenance later to change the filter dryer and stuff. So we got everything oiled up and we're ready to put this thing back together. The equalizer tube here is a crappy spot. This is where they had it at before. It really shouldn't be there. I am on a flat spot on the copper, even though it looks like I'm really close to the braze joint. But I don't goober my stuff in there so all the debris should be inside the joint. That's where the work is getting done. So we're going to do this one back up. It really isn't going to last. You can put it a little further down, but it's not going to make that big of a difference. If you went back here, you'd be right by the distributor tubes or the distribution block manifold, whatever you want to call it. Alright, so we've got our filter dryer in there. I didn't even use POE oil inside of my burns and stuff with the POE in it. All mounted here. I think they had that up here before. I didn't want any of this rubbing, so I kind of got that there. I'm going to tape this. Well, I ain't going to tape it to nothing, actually. I'm just going to keep it isolated because otherwise, if it's this, it might be heat transferred with that cold. So I'm just going to leave it isolated there. And then we're going to finish pulling it back here on it for already about 900 and something. And we'll isolate it off at the receiver and see how it does. We're just going to try to stay under 500. But if you look at some charts, if you can stay under 1,000, after the Blankoff test, say you stop and blink it off at 500, and it stays under 1,000, there's tests out there that say that's good and tight. So we'll see what we get here. And when I do my Blankoff test, I'm actually closing my receiver there, partially closing my valve, and then just see what happens. Point you get a balanced time with the logic here. Let the filter drive you around. 52 ounces. So 52 ounces is what it is. I guarantee you, according to says high pressure, 52 ounces is 3.25 pounds, 0.25 times 16 comes out to 4 ounces. So 5, 6, 7, we went over by 3 ounces, which I'm not worried about. Let's see where we're at. Look, I've got a lucky there. Sight glass is not quite green yet, but I can tell that it's slowly changing. There was quite a bit of oil down in that pipe down there, so I'm going to go ahead and isolate this and get that straighter core back in there and then we're going to run this thing. Looks like that one's in. And there it goes. It's about 75, so now I see probably 70 degrees in here, so 80, 90, 95, so about 25 over in yet. The evaporator's running 25 degrees. Got a nice little sight glass that goes forward. It hasn't turned green yet, but it's getting there. Pretty good so far. Already gotten our trap here blown out when we first did all of our prep work, so that's finished. Pressure looks pretty good. Let's go inside and see how the evaporator section looks. It's worked out kind of nice. There's more of them like that. That thing's so nice to work on.
