 All right, so we're replacing a water valve on an ice cream machine The water here is kind of bad So this has happened a few times Basically it controls the refrigerant pressure by the water coming through the system and the more the pressure increases the more it opens the valve and causes the water to come through and Controls head pressure that way so water pressure control valve So we've got that to put in and then I don't know If we got anything else we've got to do. I've got so many freakin parts in here So there's the valve. That's what it looks like. I've had to replace these before so we're gonna do that again and Kind of see what else we run into I'm sure there's other things we've got to do here It's always something broke. So let's go take a look and see what we got See where the ice cream comes down right now. They're running sanitizer through it It's in the back machine. It's just As usual a lot of things stacked inside of its water cooled Looks like they got new lines on this one, which is awesome We got the good stuff this time. So hopefully they have less problems than what they didn't have them It goes back to the walk-in cooler and They keep that pipe cool, but we're bringing the cool air from the walk-in cooler This it's no longer approved by some places, but if you're a grandfather, then they let it go this one here So all the same same thing so We're gonna go ahead and pull it out. I guess it's just like a little water. So we'll go ahead and Get that out there miss things been Treated hard So I had to put hot shot to in this thing. So we didn't even know it was in it before You can see the emulator here. It's what I'll call it It basically boils off the refrigerant and they run the hot gas through it and obviously was leaking so my bypass that that was before me The compressors are cranked in here nice and tight can't hardly get into it yet, you know vows that just barely I mean This thing has been ran hard Very very hard. So here's the vows in there right there It's getting hard real hard It's just matter of time to let them shorts out I think it's worked out many years if you've ever counted and seen how many times these things are on on and off on and off on and off You'd be blown away That one There we go. Yeah, like how it goes out of there. It's just pretty cool I'm not seeing anything drip right this give a moment Won't play with it for a little bit and make certain that's what's wrong with it They ordered the parts that they come change it That the refrigerant line comes over to here Chances are this doesn't have a straighter for that. So we'll either have to pull the refrigerant charge Or try pinching that off which I've pinched it before which is usually what I try to do And for you people out there in California, you'll have a ship that about this and so the water just basically comes right down the drain Now the alternative to this is have a water-cooled condenser like on the roof or circulates the glycol Or you can do a pump and dump basically where we just pump the water through and dump it down the drain if you're on a On a well or if you're on some place that has cheap city water, it's not a big deal Otherwise it can get kind of expensive So it's kind of wasteful usually Two gallons something like that. I think a minute maybe a little more. I'd have to check the book I forget I'm going off to you a thermal shield thermals usually one and a half gallons per ton and So I forget exactly with how I'm looking it up, but it's it's a considerable amount of porting just people that pay a lot of money for their water So and I'm seeing what looks like it's leaking out of there down there So I need a call a guy There it is There it is leaking out of the How that area there pop this back off those belts are looking a little bit bad They do their own maintenance on that so Like I'm dealing with that see if you go to Not be a little there missing Usually goes up there So here's a better look at the vows basically just crank them in or out to adjust your head pressure to maintain whatever head pressure you want and Nothing fancy see if we can find out where it's leaking out of here All right, so we found out which one of those it's that one over there You come down to here you can see Water and stuff that it's leaking off of it So we're gonna get that off of there Need to follow that refrigerant line there and see where it's going to it looks like it But surprising that hasn't leaked Yeah, it comes over there. So now we're gonna go on the other side, which is not really Literally gonna tear whole all three sides off this machine to get into it Things have changed so much over the years crazy amounts We can come over to the other side and see I mark DC to find them left and right And when you come down to here, you can follow that refrigerant line that goes to there Which also splits off because the high pressure reset So if the water don't run it shuts it down that refrigerant line goes From right there up to there so we could try pinching that Or we can pull the charge Which it makes those about two pounds If I remember right this thing has leaks and just see the Rough rough work. It's been done on this thing Yeah Go ahead and get that let me figure out what I want to do here Pardon me says good and pinch that thing that way you don't have to screw the charger charge So I think I'm gonna do that I think I can get in there pretty decent on it I've got the unit off so won't run Right pinch it about right there I've got two different tools The Imperial 105 ff which I have a link to this down on my Amazon toolbox down below and then these generic ones here Yellow jacket made a pair of them, but I had problems with these sometimes not pinching things off very well so like if you You can see there You have a little bit of a gap and when you think of the thickness of the copper It usually doesn't do too bad I'm gonna try these today just because it's so hard to get in there when you're doing these you need a little more room Nice thing about this those that rerounds it. However, if you're using your nipx pliers with the Like the crescent wrench style you can actually squeeze it because all we need to do is get the pressure through We don't need crazy amounts of flow like you would for a liquid line or something like that So I'm gonna probably go ahead and go with these here. They've been doing a pretty good job These are some cheapies. I found these have been really good. I'll be honest with you He's been halfway good. So let's go ahead and do that if it don't work. I'll pinch it with those But this should be fine Now some I definitely strongly recommend. I usually am not a big Harbor Freight pan, but things like this you just can't get wrong These are the Pittsburgh Automotive hose clamps pliers these things work really really good if you're working on ice cream machines these things will pinch water lines off Mixed lines you name it and holds back beautiful. So I had these things since 2017 I always date my tools which seems weird But it helps me keep track how long the tool lasted and stuff So you're gonna get that on there and then now we don't have to shut down the water on all the other machines and they keep on running So we got it off there and Works pretty good. There's some major pressure behind this thing And we'll be chopping that end off there because you tell it's been split So we'll go and get that redone when we do it a lot of hokey pokey going on here a lot of homemade repairs So we'll just keep on doing what they've been doing. That's not a barb fitting I don't think it looks more like a Some sort of first-generation pecs fitting or whatever Okay, so it came undone just used a right angle tool got in there and loosened that up Got it out of there, but the Frigid cap tube there's wire tied so it vibrated into stuff So kind of pinch that thing off yet. We'll do a little rig them around and actually that should work out just fine I don't know which way they get this in there. Usually I like to see it on On the outgoing side because that's usually how you do it on geothermal, but Get it set up so that's a flow through I guess that's my positive sides the flow is gonna come that way so yeah, it works out well It's probably Yeah Probably was wired in wrong to begin with but it's the most part of there's two philosophies either keep it under pressure all The time that way it's always got water on it, which should really be the outgoing side that way there's water in that evaporate earn that condenser or Let it drain out, but honestly it really should be water in the condenser. So when it kicks on Got some in there to absorb the heat before it kicks on so Whatever, we'll see if we figure out which directions what it's a little hard to tell a bunch of anything right now see why that's a little easy to do and then The other type it gets in there a lot better, so we should go get a backup wrench on there and get that thing Done in we'll bleed this off to make sure it's completely pinched All right, so we went ahead and cleaned up the inside of that bell so you can see how bad it looks I've got the backside fairly decent Got these fittings taped up I should say got my Sheet in here on my q-tube. I'm gonna bring it through here so it's a little less likely to be such a pain in the butt in it won't rub through on anything and I'm gonna go ahead and go with the fact that it's been like this, but I'm pretty sure this is supposed to be going on the outside of the unit Let's work this long why change it now these things already rated beyond being replaced so We'll put it back the same way it was. Otherwise. I got to re-pipe everything They basically got them you would think it's backwards, but they've been keeping like this forever It's one on judgment calls. Do you change everything for what reason so? Let's keep on trucking. So we've got that on there Got room for gauges for when we need to hook up our gauges and get in there and screw on that I'm looking at that set there like that. It won't rub through I'm gonna hook my Service files on there and make sure my head pressure control is set correctly Got everything hooked back up here and mounted up everything's good there And then once it's running on to whether that flare fitting is gonna leak or not She seems to be holding good around a hundred degrees and our sight glass not that you should charge off of it Staying full Our other side looks like it might be just getting a little bit low which wouldn't surprise me this thing's got leaks and a coax coils I believe It they're very very small, but because of the age of the machine It's not really worth sinking a lot of money into it, which is why they bought the other machine off of us And that's been a better investment of a lot less problems. I thought it was low But I was looking at the wrong side glass Like I said, you don't want to charge by that but um I'm not gonna go into a great feel of detail on a lot of this stuff because it's very proprietary far as learning it and you know, there's very It's very limited on what you can find out there on information There's not a peer to be leaking. I think I might go ahead and valve it back off because it wasn't low I thought this was one of the ones that was leaking more Brutally, I got everything soaked I don't have any leaks from what I can see there in here, so We're looking pretty good For the aging machine, so I'm gonna let them know about these belts. They're starting to look a little bit Little war, but they they keep a pretty good idea or a good eye on that stuff. So That's about it guys Go ahead and go under this next machine over here That's got a control board that they want to change out because it's cycling too often They already change a sensor and they order their own parts and just have us put them in sometimes It just depends on what it is. So we're gonna go ahead and get that put in now and Double-check for any Wires that might be rubbing into things because man it it happens with these machines Happens quite often All right, so we went ahead and changed that board there because it had some cycle rate problems So after I went through all the trouble of trying to program this thing and then checked out the cable and everything else and actually Check pin by pin to my keypad membrane and all that The board they bought on eBay Ended up not being exactly the right board. So they Part number the board and a few other things didn't match up So there is something for anybody out there that tries to get parts online be very leery about buying them from places like eBay or online because You might be thinking you're saving some money, but unfortunately they just bought this board and it's worthless So basically now I've got to sit there and take all this back apart and put the other board back in and Just was a total loss all this here is unplugged right now You don't want to get any of this live and even then you got to make sure you're you're Completely grounded out so other than that guys this one here ain't much to show it's just a Frickin milkshake machine the blender on it. So I Appreciate you guys taking a chance to look at the video if you guys enjoyed it You want some more like it make sure you subscribe and click the notification bell We're on Facebook under HVACR survival and until next time guys. We will catch you on the next one So here I am getting one of the other machines ready at another place We got the you 431 I2 and we have you 431 Pre-turbulation so Went through look for leaks Check the belts changed a couple contactors up here. This was probably one of Stoning's biggest pain in the butts out there. So we changed on that one that one These ones here. They made look a little bit Pitted but they're really not this is for the this one's for the drive motor same thing with that one and the compressor The compressor ones are mainly what I changed. They're gonna order some new Day and night controls here potentiometers. Those are out of whack You can pick up some crazy resistance readings on it and stuff And then like I said, we checked the belts went through look for some leaks. These are water cooled pump and dump I sold them some extra contactors for later and that's what I used today. So I had those setting here Believe it or not. Those actually worked out great because these are 24 volt where the other ones are usually 230 volt Got that in there Check the mix pumps back here in the back made sure that those aren't all wore out So we're basically right now kind of wearing off this rough edge because this is an old machine you can see right there where Kind of I think it's a stupid thing to focus you can see the sharp edge here and it tends not to want to pull out of the machine Stainless does not focus for crap There you know, that's not horrible. It's what I'm doing. It's kind of in you know, here's the new machine even Even this new machine here's got some wear already and they lubricate these things but they still wear out So using the old handy-dandy file and kind of just rounding that off a little bit So that maybe it'll pull out a little easier then we're gonna get her together and make sure everything comes down to temperature that way It's good to go and that way they can open next week So that's that's what we're doing here on this one here. Just basically do is preventative maintenance Which is always smart to get done in advance so That's about it this old beast here Have to look up the date, but this thing's old and still going great. So that's about it for this one goes
