 Hey, what's going on guys? So we're gonna do a compressor change on a very old Reach-in freezer. I tried talking them out of it, but they wanted to do it because the machine's still in good shape So if you guys end up liking the video and you want to see more like it Make sure you give it a big thumbs up these things take a lot of time and I'd greatly appreciate it It helps build the channel. All right, let's go ahead and get started She's a real beauty Clark they ain't in bad shape, you know compared to today's stuff out there The seals are in pretty good shape so dirty. This was a 502 system originally and it was switched to 404 So we got a compressor with PoE oil. So like I said on the last video, we've got Contactor there I used to isolate the compressor from the thermostat to help it last a little longer than a few weeks which is the last problem we're having and We've got the compressor there. It's just beat and tired Convincerating too bad of shape. We're blowing it out a few times I'm gonna add a sight glass to this thing so we can kind of see what's going on. This is a TXV Which we took kind of moderately adjusted. I got a new T-frost termination fan delay switch forward to let's get this evacuated and get started here Look at all that oil Look at all that oil leaking out Obviously we got an oil trap going on here Still debating whether I want to redo this nasty looking Bent up little Heater coil out of there got so many old capacitors and relays overloads Mice nests stuff like that. It's all great We went ahead and measured this. It's about a pinky to a thumb long and about Fist and three fingers wide see half of it's not even in the pan anyway. So I went ahead and started bending Here's the new compressor New seaw dryer and a defrost termination switch which I just went with the same one we use in the Walk-ins because they actually work Yeah, just a little bit different since size, huh? This one's made in 2021 and this was built in 1990 Area they make this a little easier to wire up And just so you know this has an internal overload protector. So using the same little rubber Deal here. So don't be too concerned if it don't have a thermal overload there So we got that in there now that way we can bleed nitrogen through We're going to probably reposition this thing so that the lines are this direction You've got your suction, which is only I don't know if you're lucky half inch This is massively Oversized I sure hope this is the right compressor. All right, so I pulled the specs on the old compressor and it came out to be in 7030 btu This one's 6680 this one here half inch. Yeah, maybe half inch suction line And it looks a lot like Boy, I don't look very big. This is why I told him I even put it in the paperwork. I said look I'm not guaranteeing this thing's going to work right. I really advise against doing this I don't think it's a good idea But they chose to do it anyway, so whatever Hopefully everything works out. All right, so technically this is half inch I'm going to expand it. Maybe I don't know. It's the same size physically as my pipe For half inch I really wanted to leave it going down in there, but I may have to sleeve this copper instead. I'm going to cut that copper line there You know one thing you got to look at here is this is 25 years old at least At least I mean it's 1991. I think 92 ish When equipment using 502 so And it wasn't designed for 404. It wasn't designed for you know all this crap. So We're just going to have to make the best of what we got to work with Some holes in that heavy metal and just ran the screws bolts right through it It's able to get two of them in there. She ain't going nowhere Got my electrical mounted over here the mounting bracket before just would not work And like I said, the electrical is good. I can get into here. It's not idea, but it'll work This can always be removed by the two quarter inch screws and gotten into And uh, we're gonna take our piping up and over nitrogen feeding right through the What you're seeing there is between moisture refrigerant and oil That's in the lines that was probably being baked off Even though most of it was new So you got uh, you do pan heater in here. It's nice and flat. It's actually down in the actual pan I'm not a real fan of going from quarter inch to three eighths and stuff and back again, but I did verify the size of the compressor and like I said, we're only a couple hundred BTU off Um amperage wise is the same so Here's the main everything's gonna work fine. I guess we'll find out here in just a little bit if it's an issue or not But we got our hot block on our Our gauge air. Hopefully that's still greenish good Because you gotta be real careful not to get that too hot. Otherwise you will destroy that center strip. It's inside there Can be replaced it. Luckily all you got to do is Take a little nut off the back What I've done on bigger ones Is I've actually just taken it completely out the smaller one. I wasn't as worried about it I'm not a big fan of putting a bunch of Heat block wet rag whatever on the first dryer um The reason being is it can take forever to get that joint hot enough and you're putting craft loads of heat on it My feeling is you're weakening the metal and everything else. So it's better to get on get off That's my feeling. I'm not real thrilled with way. This is it will self support Because that's three eighths there But I really didn't have a whole lot of options. I was trying to make everything accessible The electrical from all different points. I believe we pulled a good amount of solder into the suction line there On the compressor had to go uphill on that one if you noticed all these here I did them so that uh, it was all going down into the pocket instead of Up into it. So to me that's just Uh a lot smarter to do it that way Maybe we did our flare down there And we will make sure none of this is vibrating when we're up and running if I have to I'll put some Some uh split nylon vinyl tubing on there So I'm going to go and do the pressure test now and see what we got make Through the high side make sure it comes through on the other which obviously it's doing but Just to be certain I got them sprayed down. I don't see anything leaking And uh about 210 on it so that should be more than enough Let's get this thing cleaned up Crap I'll leave residue on there. It'll end up causing green muck and all kinds of other and stuff make it look nasty I went ahead and got some of the mist cleaned up Which is what I usually do as I'm starting to be closer and closer and get stuff out of the way So I'm doing this one hose pump thing and the last time I did it It really sucked like literally not in a good way service valves on the receiver have a tendency to leak There we go. We're finally Dropping a little bit or what? 19,000 so We'll watch this for a little bit and see if it makes a difference. I I usually hate Doing one hose, but well, we'll see how she does. It's a small system So here's what we're working at like I said just about got her up and going Just got to do this Switch yet, bitch Yeah, right here So we went ahead and replaced those Buck connectors with insulated female connectors and then just use the factory Uninsulated ones there and then they're wrapped them with tape that way we kind of keep away from everything It'll be fine That'll be easier to change next time. Let's go ahead and continue forward. We're down to 495 Micro-eyes So Sorry to valve it off and see what happens backseat this Receiver here. So it holds 32 ounces originally. I just want to ounce shy We're gonna kick this thing on we're gonna watch amp draw and all that at the same time Had some high amperage last time. I had a chance to talk to the guy from Emerson Trevor Matthews who we had a couple well two weeks ago. He's told me that the mcc or mcca amperage is the maximum Current that that compressor will have until it trips limit. So we're going to go ahead and clamp this thing on the common We're going to watch it and see where we're at I think I need to look again to see what my maximum current is for this thing because I don't remember Dropping back now, which is awesome. Now with that fan delay, those fans aren't going to come on right away. You're too crazy To change in charge and stuff like that. It's always more pain to take it back out so far We're at an 11 degree super heat. Holy poop on a stick Things doing good. And I think whoever replaced this compressor long ago Didn't have quarter inch and they upsized everything because they were In a hurry and so I should have looked a little closer. It won't hurt nothing Uh, we'll get a little extra refrigerant in it basically a little bit of an extension of a receiver Far as the uh after the receiver and then far as this part here, I mean it's just a little bit of extra cooling heat sink so So far so good It's the beautiful thing is is I can lift up my thing and see hey my coil is starting for us, but I don't have fans running yet So we can't really do a whole lot of anything in particular just yet There's what I'll shoot before I added some and we're at about nine ounces I had about one to go for that dryer is about two and a half to three. I think somewhere not both part And fans might have just finally came on to head pressures running in there at 233 And still got a seven degree super heat Which is beautiful. We're running about a hundred degree condensing temperature. It's probably about 75 back here So 85 95 so about a 25 degree of rambia And we're solid cyclists. So it's so far this thing is working beautiful Not worried about that frosting on the compressor because we have proper super heat We're checking it right after the valve coming out of the evaporator. So we're good there And we're going to write down exactly what our final Refrigerant level is when we finish up. So we'll have it for later Because a lot of times I'm the one that comes back. So I want to make sure it's uh accurate and it's easy for me for later We'll check our clock here see where that's at A little bit off, but we'll let that go for a while. This is uh This does not pump down or anything like that That's a good thing 11 and a half amps run about a nine degree super heat 256 on the head We got a solid sight glass there Things don't look too pound of line super heats good Condensing temperatures a little bit up there. I mean We're starting to pull you know The heat out of the box, which you know that could come back down. I'm not changing anything right now I said run about 9.6 uh degree super heat. So I'm probably gonna put the cap on there and leave it go for a while. That's uh, pretty good in my book I like somewhere between six and eight on most normal freezers I'm not sure what the effect was on this little burger. I would say probably somewhere in the same vicinity All right, so just scan that Compressor and we're pulling up here. Here's your mcc maximum Compressor current. I believe is what he said it stood for So this compressors maximum amps is 20.5. That's where it trips out and goes off on thermal overload the 1.56 is the ambridge that you use to Choose for your breaker selection the wires And then the other one is for your contactor selection. So Contactors just a little bit heavier duty Lock rotors obviously 77 which is probably on there. Yes, it is I mean, it's a really neat app. You guys haven't already gotten it. I mean, you can sit there and see what your capacitors are your relay The voltages that kicks in and out on The resistance of the windings But all I ended up doing Was to find out scan This ends with a cfa clicked on it boom There you go. And then I picked my refrigerant 407c 448 449 and 404 Around 404 This is rated for extended medium temperature poe oil So capacity like I said 6680 the other one was 7,030 350 btu difference, but I don't think it's really gonna make much of a difference honestly. It seems to be doing really good so far Super heats a little high yet head pressures coming down You noticed Cyclases starting to flash some So like I said, when we don't let this thing run to box temp That's where we'll make sure we got a solid uh cyclase every in the normal operating conditions. We're good Checking back to the amperage. Uh, we're running right at 10.6 Glows they were doing a pump down on this thing just to see if they can do it Which my head pressure is going up some here once we get down to it just for kicks Interesting cool. So I would say that we're probably fine on charge She's uh, gonna go up a little bit. I didn't take it completely super low But I'll say guys, we're probably setting good. Um, I've adjusted the super heat a couple times We ain't quite the box temperature yet. I'm afraid to move it too much and have to go Go way too low After you know gets to temperature So probably just gonna leave around the 12 mark I think I opened that up quite a bit from the way it was even before with the other compressor I think it's been having issues. So we're gonna go ahead and open this back up And get this thing going. I think we're just gonna go ahead and head on to our next call And uh deal with we have any problems deal with it later, but Right now everything seems to be working good Which is great There's nothing wrong with a good successful Change up you got everything insulated And that seems to be working pretty good So guys if you enjoyed the video make sure you give it a thumbs up And don't forget to subscribe Check us out on facebook and instagram and until next time guys. We'll catch you on the next one
