 This video is brought to you in part by TrueTech Tools. Quality tools, essential support. Good morning, everybody. We have a walk-in freezer that is running warm. So we are going to go in here and see what's going on. I just checked the controller. And it looks like it's been since 1 o'clock in the morning. On the 14th, today's the 15th. So it's been down for a while. I'm going to let this thing calibrate out here. I have a feeling we've got a leak because it's short cycling the compressor. We're zeroed out. Let's get in here and take a peek and see what's going on. Got an HVAC system here. It seems to be working. We've got line sets going up through the roof there and going across to a little compressor room over there. You can hear it kicking on and off. Let's go out here and see what we got this freezer. I'm in super mode, which is way sensitive for a big leak. But this gets me in the general direction. Let me try cloud hunting mode. Sometimes that works good. Sometimes it's better to use the notch feature. Just really depends. If it's super low because you're far away, you may only get one or two parts of a million that wouldn't normally trigger. And getting better as we get closer. As you can see here, we go into our alarms. It's obviously high case temp. Go back, go into circuits. Go into walk-in freezer. Go down to temp, graph that sucker. And zoom in. We've got quite an area here. So we are fine and dandy in about one o'clock area. And it never came back down. And boom, never came all the way down. And boom, you can see we're losing refrigerant. Lose, lose, lose, lose, lose. Pretty obvious what's going on here. There's the mid-strass defeat. See oil right there and here. Let somebody drop it. Just let that good rest because it's not obviously doing much. Don't like that way going around like that. I want to say it's probably not in here. Batteries all gone. Not even on the low. I think it's something that's really not liking it. We're doing our parts for millions to see how strong it is. But that's not going to take the whole thing out, which we don't know how low it really is. But yeah, 50 parts. It's a, ooh, what the heck's going on there? There's quite a bit of oil there. Definitely got one length there. I don't know if it's just the straighter core or what. We're going to have to grab some soap. But we're definitely leaking through the cap because now it's a little tighter and it's not going as nuts. And it's definitely, definitely the cap. We can fix that with a brass cap or put a new straighter core in, which is how I would do it. All right, so pretty sure this here is probably the air conditioning system you've seen down here in the ceiling. So it must be one of these here. First time I've been here, so I don't know where anything's at. Unless that one leaks enough to take it out, I guess that's awful quick procedure for it to get up to what's got going on. And watch this. We're getting a little something there. Something up underneath there in the little rubber boot area that we got to rub through. We're only hitting four parts per million. That could be just what's floating in the building which leads you back to how much did we lose? Have no idea. Think what we may end up doing here is start recharging it, get up and running, see how many pounds I have to put into it and kind of base it off of that. Everything tends to get ran bare bone minimum levels that way. If there's a leak, you know it real fast and you don't lose a lot of refrigerant for nothing. You can see they've already made one repair right there. So it's very probable that there's other places in some of these, it's seeing a huge rack or anything like that. So it's not like it's got, I bet it's got probably 35, 40 pounds in it maybe. This is after I tightened it. See if we got much going on. It's after tightening it in the unit's not running. It's not even running. It's tight as I could get it. I'm not big into spraying solution into the valve core but yeah, oh my gosh. Get a little bit of that on the finger. Watch out, that thing's blowing out of there. That is ridiculous. Wow. Well, blow the refrigerant out that way. Let's go ahead and get this core changed. It might have been able to be tightened but honestly I don't even want to deal with it. We're just gonna change it. What usually happens is that discharge gas, it's just so hot, it just kills these things. Use our finger here. I like doing it like that. That way you're not shoving it all in there and then when you're done, you can always just burp it. Get the residual out of there. Like I said, that obviously the cap's worthless. So we're gonna go ahead and put a brass cap on there as an extra precaution. I'm kind of on a kick on this and just so you know, those are flat pliers. Now most of you are like, yeah, you're showing me something I've already seen. I'm still, I get a kick out of that one guy who just ran his mouth. He's like, you got on there with channel watch. I got done watching as soon as I see that. I'm thinking, but get out of the 18th century. And I didn't mushroom that down either. That's what a lot of people do. They crank them down, smash the lips on that thing. Then you gotta drill it out and everything else, total pain of honey. So we've got that. I'm gonna spray this piece here because I don't like the way that's dark and flare fittings. I'm just gonna go ahead and, even though I didn't get nothing on it, I'm gonna do a poor kick it on because once it's running, it's too hot it'll just kind of boil off. We have a low pressure switch on this so it didn't go into a negative. That's why I'm not gonna change the filter dryer. All right, let's get this weighed in here and see how much we end up using. So our discharge side there was at 140. The measuring, go down to charging. We're gonna do manual charging, hit enter again. Weight scale should pop up right there. Zero, wanna zero weight. Now you do have to do an update on this manifold to get all these features too, just so you know. So we're connected there to the test of scale, zeroed out. We're on 404A. We're gonna go ahead and kick this thing on. I do not see any leakage signs from any of my big blue. We're connected to our liquid line there. We are having to dump right on the compressor, which kind of sucks, but it's a big boy. We'll go slow and easy, we'll be fine. Unfortunately, I don't know why they wouldn't have put a port back here where the accumulator is at. That would have been a better spot for it that way it could have mixed before it got back here. But either way, let's go ahead and kick that on and go ahead and start adding. You can see we already got acid liquid there. That cyclist looks like crap, but be honest with you, that cyclist over there don't look no better. Through the refrigeration HVAC guys out there, this fan here, you see these usually on compressors that are used for low temp, the compression ratio. Okay, we're already, we just go clear already. Right here at four pounds, looks like we started to go starting to. So right now what's going on is the headmaster outside is starting to open and close because our pressure's finally gotten up there high enough. It's a hundred and eighty pound headmaster out there. Just went through solid, which don't mean a lot. At about 12 pounds and a half. I'm gonna stop for a minute, see how it does because we got to give it a chance to get those evaporator fans on. Oh, so you're gonna shut down on me already? That's nice. I'm gonna have to go look and see if it went into a defrost. I assume since there's no clock here, this must be done by the panel downstairs. Okay, it's in defrost. So we're gonna go enter manual defrost. This is a tricky one that I never knew how to use because nobody showed me. Hit that and go to end manual mode, enter, look at that, it's in drip mode. So it's gonna drip for a bit, you're going to set up, you can see when your set points are negative five, defrost, got electric defrost, duration's 45 minutes, down two minute delay, five minute drip time, defrost times, number of schedules, three at one o'clock in the morning, nine o'clock and 1700, which is five. You got two inputs here on the board, outputs there, alarms, high case alarm 20 degrees, delay of an hour, 45 after defrost, and unfortunately this thing is not on the network far as I know. So right about 15 pounds and we're going back through and now that we've got 216 pounds of pressure on it, looking for any additional leaks. Ah, super, let's try it on high, the system is this. There's one leak, so that's not gonna help with none. So I have that leak there, plus that one over there, plus I bet you there's more. Everybody's like, don't do it in high super mode, you don't need no super mode high mode, we're looking for a big leak, we're looking for a really big leak. Well guess what, you can have a bunch of small leaks and have a big leak when it's all said and done. You figure you need that super mode when you're sitting here fighting against the fan that's blowing everything away. Well I tried tightening it up and it's still got a little bitty leak there. Let's go ahead and pump this thing down, get that fixed. We've got a receiver valve right here on the back, so let's go ahead and get that done. See, we're pumped down, watch out there. This is a nylog for the rescue. This repair is brought to you by Nylog. You can pick this up with your tech tools and use the discount code survival net checkout to save 8% on your total order. Look at that, get her, get her gutter. And she shut off about two. Oh, she's not liking something. That valve's leaking like a sieve, good figure. Oh yeah, look at that. We got a leak of drama going on here. We'll go ahead and isolate it here. Also, that way we don't have any back pressure coming from other parts of the rack or not the rack, they're the parts of the system. It's not the best looking flare I've ever seen in my life. Well, I guess it ain't too horrible. You can tell it wasn't lubricated on the back side very well. Like if you do that with my Navec flaring tool and just do a whole brand new one. All right, so I screwed that back together that way we keep all the evaporating refrigerant inside there that way that nothing's getting displaced by oxygen. We've got the Navec NEF 6LM, this thing is sweet. All we gotta do is get that off, clamp it up, and we're good to go. That's a half inch, which we can look right here at the top. There's half inch, pretty sure that's half inching it. There's that five inch, yep, that's... All right, clamps down, that'll be half inch, yep. All right, and then when we chuck it up it's gonna stop there, boom, slide it on, and good to go, let's watch and see. Put that notch right there on the flare, the way you don't chop off more than you need to, and get this thing decimated. Now, I've got two different flaring tools. I bought a rigid one here that does okay. First stainless steel and a few other things. Doesn't do too bad, I paid a lot of money for it, and I don't think it's all that great on some stuff, but honestly, the old fashioned, the deep ring tool here usually does just fine. We're gonna put that copper in there just like this, little stainless steel thing's gonna stop it like that right there. We're gonna slide the tool right down to it, right over top of it, clamp it in like that, hit the button, and then it backs itself back out, and she's done. Release it, pull it straight up. Pull that off, looks like the perfect flare to me. Now, rough edges, a little bit of optical illusion there, I think where I pinched that a little bit, but that's my fault. So, we've got a nice flare there, make sure there's nothing inside that edge corner that I didn't get out. Yeah, there was a little piece there, good, got that. Yeah, that's why you gotta be really careful when you're doing your deburring that you don't get in there and do what I did. But, it would help if I wasn't crammed right in between here. So, put a little bit in there. This is refrigeration oil, so it doesn't matter if it gets inside there, the whole reason for it being blue is that it is made out of polyester oil. That's on the back side, so now it's gonna spin like it should, put her back together, like that, nice mating surface, screw it together. You go out and grab your torque wrench, but less is more, usually about 40, 35 pounds, I think, something like that, but the biggest thing is just having a good flare and having it lubricated. Now, if you're watching that refrigerant, it's, even though we're there, it's boiling out the whole time. Now, we could do a little purge over here to this flare, not over here, but we're gonna be fine. Let's go ahead and open it back up. You don't pull vacuums on this. If you look at my valve here, when you crank it down, it's open to the top side, it's gonna go that direction. This one over here, same thing here. When you crank it down, it's gonna block it down here and you're gonna go to the receiver. So, there's no way to pull a good vacuum on it, so that's why you'd be fast about it and let it boil off. So, we've got that opened up, and I'll listen to here, we can check it, it's got a packing that we can actually tighten if we need to. Like that one's fine, it's stupid tight, just snug it up a little bit. This one does not have a packing that can be repaired. So, unfortunately, luckily, it's got a metal cap that's actually gonna seal it, so we'll back that out and you can see that I can feel it leaking. Sometimes we get lucky and they won't hardly leak at all and you got them back seated. It's got a little copper ring in there, tighten that up. Felt nice and solid, not seeing anything. Lots of vibration. Quite good, these loose clamps. See if you've got anything on it, a king pound leak, but that one up there definitely was. Gotta go up on a roof, you gotta look around up there. Like I said, this thing is pretty slick. You can get this also, True Tech Tools, have that sent it to me, I've been really happy with it. Depending on what size you're doing a flare, sometimes you need adjustments, you can do it right here on that right there and that'll adjust how far it goes in. And then when it locks down, you just push that button right there. And it's an orbiting flare. It's got a flashlight right there when you hit the light button. It's got a readout right there. Comes with a battery charger. The battery, I've only charged it once and I didn't get to when I first got it, it's two amp hours. This thing is just crazy how long it can last. I showed a tar install manager and stuff and recommended they get it just because it's so simple that it's hard to make mistakes and I showed them how easy it was. And I think we got one, I'm pretty sure. The guy burrs it properly and gets that thing into place right where that stops it right there. You just can't do it wrong. And as it starts doing it down, it moves that out of the way. And it's really, really well built stuff. See the pin there locks together like that. And it's slick stuff. I forgot to show you too, there's a flaring gauge here that guarantees you've got the proper flare. You can see there's an edge there that fits in there, it stops after there that way. You know that you're actually hitting the right spot. It's actually got a measuring device on the back side. But that right here is pretty slick. Comes with that little wrench here. So anyhow, jumping on to what we've got going on here. The refrigerator we've had is 15 pounds. If I had 15% of that, you're looking about two and a quarter. So you need at least two and a quarter at a minimum, probably closer to three or four to make sure we stay solid even in the colder weather. I got to go around and check it out for any other additional leaks just to make sure we've got them all. So it appears that must be the freezer just like you see it downstairs. The freezer's on this side. The cooler's here. Well, that's cooler for a stand. Like I said, around here, just to make sure it's kind of windy. We're gonna make sure there's no 15 pound or better leaks out here, you know? Yeah, we still got that leakage from down below. It sounds, smells like it's kind of hitting it. But I think that's just left over from inside and that's one of the exhaust points. I have no way of getting up that high to where that's at without a lift. There's where that comes down at. You can see it comes across right there where we are. Come over to here and right there it is. So if we were cranking out refrigerant, you would think we'd pick something up. Get a supermode. I don't, all I can do is put a straight ladder up there, which is not really the safest thing in the world. You would think, okay, if we're leaking bad, it would drip and you would have some oil down here, something, because it's leaking pretty quickly, so it looks like it online on the computer in the graph. But I think what it's done is slowly gotten low and then it did its thing. All right, so we've gotten up here anyway. Gotta do what you gotta do. I don't have anything up here at all, so my place we got is those two spots that I showed you. Well, I went to the trouble getting the ladder up there in the rafters. Might as well go ahead and replace the filter dryer where we're at it too. It's looking less than desirable. I mean, I guess more thought about it's flare, so there's no reason to have gotten overheated and made it brown like that. So let's go ahead and get that changed. Pump the remaining refrigerant in there for winter charge and get out of here. I've looked everywhere I can look for leaks. I've looked up there, I've looked on the roof and I've looked across the ceiling. So let's finish this up. Let's go and clean this backside up a little bit here. Look this up this end here. Any residual refrigerant should push right through the dryer. Get it here. So we can actually bleed a little bit both directions. I'm not sure what all we can really show on that, so easier imagination. Not to use my torque wrench just because I know I've done it enough times with my torque wrench to kind of know and I'd rather start light and tighten it up after the fact than tighten it up tight as you can at first. And then once that's the case and you usually can't go any further. Yeah, let's go ahead and open up our liquid. Then we're gonna date our flare dryer. Gatter's all in there, not seeing any leaks on it. Now that we've got it running, an extra three pounds at first and I've found out my bottle's just about empty anyway, so we're just gonna finish the bottle off in there. So it'll be about 20 pounds. Hard to say if there was anything else. We can box one more time, but with that being completely nothing in there, no hits at all when I was in there. I'm not too worried about it leaving in there. See what we got here. I like that. Sometimes it's easier just to look at the fog. See how fast we dropped. An hour and a half, 39 to there. We really started to hankin' down right about in there. Then we had to shut it off to do some leak checkin' and stuff. So yep, she's doing good. If you guys enjoyed the video and you want some more like it, please give it a thumbs up.
