 All right, this should make for a good video. It did the last time I made one at this place So what we got going on is the indoor fans on the reach-in freezers not not all of them are working They had some ice build-up so they cleaned it out with water and now they've got Fans that ain't working. So either they pulled things loose or whatever I'm not sure exactly which ones which I'm pretty sure the one that they're having the most problem out of is that one over there This one's got bubbles, but if you're not running fans, you're gonna have bubbles Kind of crawl over here to this one and see what we got going on. Yeah, same thing Got bubbles there Some there these are known for leaking a little bit so I'm gonna throw in defrost to see what's going on Not sure if that's all on one That is the place I put it back in 19 Throw in defrost see what happens. So we've pumping down for a while here Yeah, I think it finally shut off and stayed off So it finally pumped down Go in there and see what we got going on. It's got the hippie-hippie shakes going on there Yeah Nice Okay, so the one that's on here because the lights are on It's the one that we didn't do it to So you've got a fan out here and out there One out there This is on another section, this is the one we just put into a defrost Which ended up shutting off all these here so we'll Put that one back on throw the other one in defrost focus on the one that's actually not working All right, so we just tested the clock the clock's cracking time So we'll go ahead and put this one into defrost see how that does Inside see what we can find out what's going on All right, this thing ain't been defrost, but for a couple Couple seconds and then just kicked out and then just kick back on I'm not sure what in the world that was Okay from what I see we have ice build up underneath the coil And That's quite a bit of it behind the coil There we go if you don't get that out from behind the coil It'll just continue to freeze up again and again and again, so we're gonna take all that out And melt all this all the way completely gone. You cannot leave any behind Otherwise it just keeps on growing and growing and growing It's a way This thing works as the air's pulled down crossed Up into the back and out and that ice down there on the bottom I'm just gonna start cutting airflow off and just continue to grow and grow and grow And since the heaters are up here on the top of the panel It will not melt that ice down there on bottom So you've got to completely manually do it by whatever means necessary which usually is garden hose Which is what we got As soon as I get this other section cleared out there, we will get busy on that but right now we're gonna start melting this out Luckily this has happened before He already had the hose ready to go and this will expand all those here Actually, he's making it Actually, it's pretty nice So we're able to get down here Start melting this turd out In here the element's not liking that very well This is a timed off defraw Determination switches and stuff have been gone for a long time. This is a really old grocery store so We uh Just make it run If you get this melted out, we'll check the refrigerant charge once everything's back down to consistency And uh, let's see Let's see how things are. There's a couple spots you can see where it's leaking out there on the discharge line Looks like there's a little bit of leak there and there's several spots that could be leaking here and there It's one of the ones where you just got a good going. Let's make her happen And just when you think you're gonna make some progress The drains here are problematic because things get down in them like little stickers and price tags and things like that so Blow it out and hope that we don't get a bunch out here on the floor because That ends up happening because these drains are underneath here The one that's going to really not be a lot of fun is that over there You can see the ice is all the way up high. So This is going to take a little bit of time unfortunately. So the slow tedious work of that coil over there is done Got everything out of the corners now. We're working on this particular one also on that same compressor The heater's working The Heater you can feel it problem is if you don't get these things cleaned out properly You block off the air flow Fans are running but no air is going through the coil and it just compounds and grows and grows and you can see right here The ice dam that you got here on the back That's the problem you have And we are going to be here for a while because that's a good Good freaking inch or two My drain should be down here somewhere in the middle Trying to find it. I have a feeling that maybe my heater might have froze Or my heater may have went out I believe I replaced the heater on here. I know I did from here out to the outside We're going to Melt us a little path in here and see if we can get that drain open first before I start flooding this thing All right, so this is going to make most people laugh Or cry So here's the drain Comes here. I replaced the drain heater over there on out I don't think there's much of a drain heater here and you can see all the freaking ice Underneath this cabinet. This is so bad So bad so See if I can get this freaking drain line opened up We're making progress If you want to call it that So luckily we're not leaking here, but we are leaking down there a little bit um I've got it To the point where I've got it pretty much cleaned out But it's still not draining for crap trying to Train it out with the gala gun It uh, I've been jamming some hot water through there. This is just the slow tedious thing It's coming out on the other side. I mean least the other one was So I mean, I know it's at least clear from here on through or at least it should be So it could be something in here in this particular spot right there. There's no heat tape at all in this particular one um About all we'd be able to do on that one is just jam something down from the top So I will probably figure out a way to do that when it's all said and done as you can see here This is not idea The conditions there's the heat tape coming out problem is the people that did their parking lot paved it up nice and high So you can see things are kind of coming out here this random stainless steel rod down through there and I mean This just leaves room for crap to get in there. It's it's There's no good way everything about this is just difficult. So It's going to keep on getting at it had to use the freaking torch there on the outside plastic There's freaking ice all down in here from leakage and Must have got it freaking melded because now it's overflowing here, unfortunately shooting out so hopefully it's turning during up the backside here We're outside outside the building. Let's take a look here and see. Oh, yeah. Look at that. Heck. Yes All right, so Now we got that part done and I will guarantee you It's going to have some heat tape going down through the center of it Why it don't have one it's beyond me. So next thing's going to be to find a place to get the wiring in there because That's going to be the next joy So we'll finish melting some of this ice off All of it actually get all this ice down here Which is all the way up underneath the freaking motors. This is going to take a while Don't take a while for sure Kind of curious how much freaking came out the other side. So it's still draining and we're still getting crap done This is not going very quickly because the water is not hot anymore Well, at least the other fans now running We're uh, I had to throw it into like the third defrost fourth defrost Gotta watch out for those uh, fans. They're a little sharp Luckily, it don't hurt too bad. You just bleed everywhere and then when you get water on it makes a mess Yeah, so all my hot water is gone But we've got all the crap from behind the coil So now it's just a matter of getting it underneath these fans, which like I said, it's going really really slow because the water's Just plain cold now, but it's it's Up to about there. So yeah, it's it's about An inch and a half two inches deep All underneath there yet All right, so we've pretty well Just took all this crap part Lean that up bend it up whatever you want to call it and had one of the other Guys helped me and dug that crap out. So now I go hook all this frame stuff back up Got some more cuts war wounds I think that's about it on that. So we'll end up Getting this thing back together and we'll juice it up. It's four Uh a little after four on friday And uh, so that's where we're at. So we've got our heat tape ready to go. I got some Zip cord there, which is way bigger than I need. It's 12 gauge and uh got it Uh on there Let's shove it down the drain run it over to the defrost heaters and tie it on that way. I was hoping to wire a constant But no good way to get into that case without drilling a hole and we're now Definitely getting later and the food is getting warmer. So we've got to get this thing done and get out of here Just finally got all the ice out So we're just about there then we're gonna have to Uh Check the uh refrigerant here, which I can guarantee is probably a little bit low But at least we know all the fans work and the only inside fans appear to be working So just a little bit more to go. All right, so we got the freaking heat Tape down the drain there and it had to have made it at least over to the tea here Got the strap to the bottom of the refrigerant line Comes over Ties into our junction box here ties on with the big main heater that goes underneath the coil there I'm going to get this thing back together and get her up and running. Um I did put these little wagos on here that I had left over from my true stuff but unfortunately the uh Like I said, no good way to get it up there. I did add a little bit of a An extension there to try to keep the water from overflowing, which worked fairly decent But um, that's where we're at on it. All right, so knock some of the ice off of it Got the inside running So far the sight glass is full, but we'll see how that changes So if I go back in it's more shelving in Okay All the fans are running Lights ain't on yet, so I'm hoping it's just a snap disk Bringing it on I got to find one more of these little clips. There's one These things are always great I got one here shelf that's not wanting to Get up quite right That should be just wonderful. All right, all those fans work Every single one of them So let me actually have good airflow. This door's about done had it And don't shut on its own You're lucky it'll even you gotta literally push it shut So I got that All right. Well at this point we've got it all de-iced And uh, that drain thing goes out There through the back wall So hopefully this light comes on here in a minute We've got to just let her come down to temp some double check that sight glass and then we'll be done Uh reasoning for it hard to say leaving doors open too long not enough defrost Um defrost clock stick and who knows I mean right now everything's checking out fine It's been almost I think a year and a half or two years since I've had to do it So I don't know if it's been done much since then so, um Yeah, that's about it. So yeah, it's just uh Yeah None of it's on a rack. It's just literally on little individual uh units so Nothing, uh Super extravagant here just basically you got a coil on the back airflow gets sucked down to the bottom Pushed through the coil up the back wall through all those uh little prongs in the back all the little holes and there's no air curtain at all in here This is a zero zone and uh Refrigerant 12 so they tells you about how old this probably is So it's it's definitely um got some age on it, but it's still running And these things are expensive. So before you go say well, why don't they just buy brand new ones? Well This is just a small town little grocery store here and uh Just ain't the way it rolls starting to come down in temperature. The cycle ass is still full um we're About 5 30 already so Um, I'm just going to come back for the lights. He's at least got his freezer running Everything's back to normal And then that way I can kind of check it when it's at temperature Otherwise, I'm gonna be here for another hour or two tracking wires down these things have been converted from Uh freaking t12 bulbs or whatever back in the day to led and it's a wiring nightmare underneath there 50 different relays and 15 different wire nuts leading to the next it's uh six so five finally wrapping it up That's the joys of uh getting stuck on something and it's friday. So anyhow, we're gonna go eat three days later All right, so we're back. I noticed a little haze going on here In the windows and it's at temperature. So Our temperature cycle ass is full. I'm gonna check this one here in the middle Looks like it's more than just a couple of them. So it just must be the seals plumb Let loose on these things you can see the Moisture there they've got a Little sensor down here on bottom that I've noticed Right there and it does a humidity Sensing and when it does since humidity a certain level it must bring on the heaters So anyhow, we're gonna go out here and check this middle one. It uh, basically Has like I said cyclosis half full or it's low. So let's see what we got going on So as I mentioned We're all back here The other one down there. I had put it at three and it seems to have been working pretty good with that So we're gonna try three here with this one especially with all the reach in action going on I don't think it's into extreme especially the summer coming along humidity going up. These are the freezers so I'm gonna add one to that. We're gauged up. We're taking a look. We're adding some refrigerant to it and When I was scanning it for leaks while it was a pump down I had a little bit of a signal here on the valve now that it's running You can see that it's leaking. So we definitely got a leak here on the solenoid solenoid seal from back in the day They have a tendency to leak once they get that other type of oil poe oil under versus mineral that was probably originally on this thing This thing was originally uh 502 I would suspect so We're gonna go ahead and get it charged up and see where we're at and then See if we can tighten that up. If not, we'll have to get a new seal for it. I resprayed it after tightening it Which I got a pretty good turn out of it Does not seem to be leaking anymore I can tell I grow now I think very good. The sound's low Which this thing holds quite a bit It's got uh two big old freaking canisters underneath here I can't see them Usually there's two big old tubes underneath there that holds quite a bit Ain't got any documentation or anything. No Writing of what was there. I mean you can tell how long it's been here Back in the day it was HP62 which was the scientific name or proprietary name New con before they went to 404 This coil's are pretty dirty gotta get this cleaned out, which I don't have any water anywhere near here All right, so we're washing it out here with some hot water which Believe it or not That thing is kicking it right out the other side. You can see the chunks of crud It's making it through there the uh Yeah, there's some big old gunky junk This thing's packed full of crud and these little pocket hoses. I can't believe It's got enough of them to reach all the way around here. It's probably about 250 foot 300 foot and It this is what I used the other day to clean out the evaporator section But we're kind of doing it both ways here. It's Total mess back here That's where the knee pads come in handy You can see just we're shooting what we were shooting through that some of this has not completely gotten wet so Kind of working it up and down Kind of working it up and down trying to get all that through there that is a thick coil Definitely a thick coil. That's pretty wide so I mean Generally, I've noticed if you worship worship you worship if you wash it properly You don't necessarily have to use the cotton coil cleaner and stuff like that. I mean there's times where I like using it, but Not every day you really need it just depends Just depends everybody's got their own preferences. I'll use it when I need to so we got them both cleaned out You can see daylight right through these things really good now Sort of Yeah, you kind of can't there's no light back here because it's inside the wall but um It's uh doing a lot better than what it was You need to see what uh Our pressures are running now that we got actual air going through it 240s so we're not too far off It's still drying obviously The fan there is not running So the other thing I worry about with the on coil cleaner or any kind of cleaner or whatever Getting it into winding to the motor. I'm not going to tear all these motors out to do it And it splashes all inside there and the next thing you know, a day or two later You lose the motor so On these ones here, they're really difficult See them well Yeah, there you go. So yeah, we got it I try not to use that coil cleaner on ones like this with that wide There's just really not much reason to but you know, it's definitely a thick coil So we're gonna keep on seeing where our side glass is at and then uh Hopefully get out of here for long
