 All right guys today, we are coming back to a cooler. I was on a few weeks ago It was low on refrigerant. I've came back and it's not low yet Couldn't really find much of a leak or just small small signals So we're changing this disconnect box. It had a leg that was bad. We're gonna get rid of the fuses I'm anti fuse disconnect unless it's absolutely necessary because they oversized the breaker for whatever reason You know unless there's a reason for it if the breakers doing its job and its size properly I do not believe in chooses. I think they suck. So I Thought I was gonna have to kill this one too because it's kind of a man-goided mess when you look at all the different wiring But this cooler is not Actually ran in it. It's kind of confusing because they brought some heavy wires up to here from there the only did is they kind of came through and Just uses a junction box. So as always this is not a DIY channel do not do any of the electrical stuff I'm doing Just a disclaimer. So anyhow The other wire I believe what we got going on here is just for the solenoid valve because it comes into the bottom there Punches through the wall and then connects to the solenoid there. We got to go lock it out I did verify which one it was. We've got our lock and stuff You're always supposed to lock it out, but I always always make sure when it's away for me where I can't see it That I do it. We already verified power was off I've made this one my disconnect lock. It's an aluminum one. I kind of marked this locked out got it It's HVCR also got my name on the other side here So they got my phone number and stuff. So it's all there on it We'll also be doing the PM service on the R2U unit here The this unit here didn't act like it wanted to pump down, but It appears that it did so we went ahead and double-checked it made sure the power's dead. I Like my bolt stick here one of the only one approved by OSHA believe it or not kind of surprising You don't see that very often so I had one of these from long ago back in the day and Honestly, I've been having a lot of problems out of the client as things have a junk Clip here, and I just am not happy with it So I went back to the old basic that I had from like 20 years ago And everything is dead already tested this against life circuit to make sure so let's go ahead and get this thing yanked out another square D here, so we'll be able to It's not quite the same size We'll make it a little more of a pain in the butt. Of course, they've got the Conveniently placed defrost clock right here on the back side, which makes it a little more difficult to get to all the nuts So I got it out of there One of the things you guys will run into sometimes these legs won't all go back into place So you see them go up there like that? That's all the way forward This is a good way for you to single-face when it comes to safety When in doubt rip it out. So we got that out of there. You can see what they did there. They ran that wire through So we'll get that back into place And I have to drill some holes into this thing to make it fit So we know that's gonna fit right there on that one. So we know which one to punch out. We've got our fancy Klein Destruction hammer. Yeah, these aren't hammers, but you know, I'm using the side of it And like I said, these suck when they compare when you could do a Klein cramp Like they didn't do a good job. I don't know why they purposely did not align that so they made a nice perfect oval But as they still do it to this day They look like the clients, but they They ain't When he turned up messing one day and this is what I found and I ended up trying them and thought that crescent's good They are on some stuff. Just not this So we've got the bottoms punched out back punched out that thing mounted back up Might actually match up with everything. Not too bad They've got this stupid Silinoid coming through the side here It goes out through the back and this has not got the amount of surface area that the other box had So since this hole there lines up this hole I'm gonna drill that thing out and just rerun that over there. They've got all their little couplings in here It's a total wreck the way they did it a lot of extra work I Make a ten minute job turn into 20 to 30 if not longer. We got all these Freakin wires running through there to save the nickels and dimes. So I've got my old green Lee Quick cutter here. It's just kind of cool Set there and change whatever size you want. It's carbon Carbide tip here. So Get that thing drilled out That's design. It doesn't allow it to go all the way into the box and get another wire behind it That's one of the few times this little wrench has actually came in handy because it's when you're in little tight spots like this where you can't really get in there with your screwdriver and stuff for easy you can get right in there and tighten that bad dog up and Tighten it right up nice and tight and she's tight to the thing So I'm still gonna have to do a little bit of drilling here on this piece Which kind of sucks, but It was a good idea, but nothing's perfect. I guess so where'd you kind of drill from the inside out and Get that lined up, and then we'll run a connector through there Doubt take a ground out of the other one You would think they would have Bonded it to it. I mean just an extra safety precaution. I mean, you know Guess it wasn't that important. Who knows so we're gonna Junction here on this plug and then we're going to Secure it to the box It's obviously inside the unit grounded to chassis, but I prefer to have it out here At the box too is an extra piece of protection. I'm sure there's probably a reason for it But uh, I think it comes down to cost honestly So we got all the wiring taken care of there Got it all tucked in wiring it back together good to go put this cover back on We're also going to be doing the p.m. On the equipment here. So we've got the filters and belts here Also got to do I think possibly all the Coolers and stuff also so Going to get started on this too. Got the power turned back on. Let's kick us back out of defrost There goes the old Tricerate Three evaporators on this thing so the 407c just run for a while. We're gonna go ahead and get over there start on that So we're gonna go ahead and wash this evaporator out. It's fairly new unit, but unfortunately These filters have been leaking by This is outside the building. So if we get a little bit of water down here in this bottom It's not gonna leak anywhere But we're gonna get this evaporator cleaned out before it becomes an issue Got the new belt on there all dated everything straight Tension is tight good to go Kind of the coils all washed out and blew out the electrical section with air Kind of run it and check their operation got to get up a couple of wires here that are kind of Dangling across things. That's a good way to have them rub out We walk in the building and the leak detector goes nuts And it's kind of happened last time, but I didn't air the system out very good So that's what we're doing today. We went ahead and waited for it to kick on it came up and hit about 72 pounds Shut it off Then I shut off the fans for the evaporators in this instance here. I need the variable Option from the heated diode. So what we did is we opened up all the doors Out in front there. So now she's not going as nuts But we are running the fans just a little bit to help blow the air out Because it's contaminated. So we've got Several doors open on this glass cooler Open last time I had it over here right this new cooler, which made no sense because it's new coil So at least now it's not going berserk as bad as what it was and we are on most sensitive mode So let's go ahead and turn off the fans Hopefully we can find this thing because it is a little bit low after all When I came in here the Cyclases slashed before I came in I was after the coil was still wet for me washing it out So it is a little bit low again, which I added I forget how many pounds, but it was it was a few um, let's see if we can get A hit over here where it was crazy the last time So let's speed it up a touch And down here is where I was having The issues Which I know it can set on the floor Which is interesting Because we can come over here to this area And it starts to stop So it's like it's that new coil doing it, but supposedly was this coil One of the other guys found a leak on it or something and told them they needed a new one that It was uh, not done yet So we don't have nothing like what we got on the other so We walk the dog Over this way see it's starting to get nuts again. Here we go So that's on the new one and I cut all this tape And stuff off and see as you get higher It slows down and I've taken all these panels off And usually if you stick anything in there It'll go nuts and of course that's one of the things I hate about this stupid detector The damn rubber thing gets caught on everything and then you'll lose your tip Hey, I got my tip back But looks there's nothing Nothing in here. This is so frustrating because It should be like plain as day We'll speed it up a little bit see if we can drag it across the back of the coil here See if there was any leaks it should be picking it up off the back of the coil at the bottom I was hoping maybe they had a bad solder joint Usually if it's trailing the insulation you can kind of Catch it up the other end of the insulation. There's a cut on it here Nothing there Very frustrating because I got to find this stupid thing. We're gonna look around a little bit. You just sat right there It just had a coronary. It's finally slowed down. So we're just taking the end of our tip here And I'm just using my finger as a guide post like kind of dragging it like this Watch this We're up here. It's not over here on this aluminum It's right here in the coil Yes, sir right in there I'm gonna go back down to the super sensitive mode and we'll drag it across some of these other coils disposably I thought it was that coil That we were leaking on Let's go over here to this other one kind of See this is what I don't like about the h10 I mean the great thing is that fine stuff, but you gotta let it set here So you stay right there and we're gonna we're gonna take our 12 foot cord here And drag it along this back side See if we can find anything here I try not to get it too close to the dirt and the coil What I did wrong the last time was I didn't clear out this cooler First thing you got to do is empty the cooler out of the air that's in here So Yeah, we have nothing so we're good there That makes me feel better awesome. Whoops. Then what did I do and knock my little thing off again? Oh, well, she came out of retirement. We're going to go ahead and grab the D tech and make sure it finds it too that way. We know it's working Now the problem we got is it was so contaminated in there that this must have just not been able to narrow it down Um in theory, I mean, that's what it's supposed to be able to do But you know, it's sometimes just got to use practicality and Common sense All right, so we're on super mode. Let's go back in here See that's the difference between I call it digital because uh infrared is digital All in our off So still getting nothing on super But let's go ahead and drag it across. Oh, yeah Yeah, I don't like that So you got that instant Look at that. It's actually going off before I even get close to that area. So it's actually doing pretty good. Look at this I'm sorry. Mr. D tech. I I didn't Didn't give you a fair chance. I kind of gave you a contaminated room that you zeroed out on Even though you're not supposed to zero. Well, you will zero out So she's gone nuts. Yeah, she's gone nuts now Let's see how How many parts per million it kind of shows up anything over 80 look see she started Picking things up even in here like this Wow Holy crap 300s and I'm that far away. Oh, yeah, plane is day going higher starting to go down Actually Going back up again Yeah, it's definitely down here at the bottom of this coil Now some of you are probably wondering. Okay. It's probably right here in one of these loops on the end I'm gonna tell you it's not Because it's not because I scanned all this I took all these ends off Took all these ends off So we're in there on the ends and we have two parts per million. So it's definitely in the coil Let's go to super again scan this coil So what was probably happening is it was probably floating across the floor falling down prior cross winds of some sort And uh going across the floor Boom across that way. It's the only thing that makes sense to me So finish scanning around a little bit. Don't want to have to do this again later Let's go down here to this new one because like I said, I got nothing on this new one And see it didn't go nuts at all when I was down here on the floor area. So The heated diode definitely can go Berserk, but it didn't go nuts when I went over to it. So we have nothing Going on in this area here, but like I said Get over here and bam. So found the leak Throw a few pounds in there and tell them they need a new evaporator just like they did right here. So Game on so now we're going to start this thing up. It may chug a log a little bit here because the uh Refrigerant's kind of like going to come back and smack the compressor in the face We may try to rapid cycle it on and off at the disconnect see if we can Save it a little headache because there's no suction valves or anything for me to restrict To kind of throttle it. Ain't no worse than the brand new ones that do this. I'll do it three times It don't sound like it's getting nailed, but a good attempt. I don't want to take the compressor out Now things freaking old r22 originally Capable of 502 so that tells you what year it is. It's got to be at least It's trying to pump down which it could be trying to do It should be pretty warm in there because I've had it off for at least 20 minutes My voice up too bad It looks like we're at around 12 12 and a half pounds. You can see the suction frame to make sure it pumps down and Wrap it up here was basically the normal p.m. That everyone does every time Worst out the condenser coil front and backwards I didn't have to split it because it's uh only about a year and a half old And we've been on it Maintaining it got the new filters in there new belt this thing has a headmaster control one of the temperature sensing ones that goes off of the liquid line Which was kind of interesting the way it's wired which I checked and seen that if it was okay or not It literally breaks both fans, which I thought was a little odd Didn't say if there was two only do one So it's worked this long. I guess I'll leave it alone And this was a linux unit originally that had a bad heat exchanger. So They just transitioned it over and made it Uh Made it work had to bring it out a little bit unfortunately, but As you see it's kind of a behind the building not a humongous deal Got that one back together and then the same thing here with that one. We got it all worked out Then there was one over there to the right. So I just got to do a few small reach-ins Check condensers and stuff like that and I'll wrap it up If you guys like the video make sure you give it a thumbs up, please And don't forget to subscribe if you'd like to see more content like this We're also on facebook and instagram until next time guys.
