 So I just re-scanned it again and it does appear that we have bubbles forming right here. You can see it. Micro bubbles. It's such a big area all the way around there that that's... This video is brought to you in part by TrueTechTools. Quality tools, essential support. What's going on guys? So we're here for no cooling or I should say it's just too hot. What we've got is an old Beasley air handler. I don't believe I've done anything on this one. Not real super familiar with this system. It's just older than Methuselah. Outdoor air temperature. This is all pneumatics. It's Hodgepodge City. We've got humidity controls and some of it works. Some of it doesn't. A lot of it probably doesn't. It's hot deck, cold deck, which means you've got one cold coil with a hot coil and you damper between the two of them based off what you need. So what I just did prior to getting you know coming online here with you is I just turned off my disconnect box over there. I was looking at the compressor which just has trained stuff which means you can't really convert it to a different refrigerant because it'll blow up usually shortly after. We've had a few that work. Quite a few that haven't. So not the greatest you know idea to try to do. So it is R22. So they're looking at about probably 2500 plus dollars in refrigerant. What we've got here, we have a sight glass that was completely looking empty. We've got a hot gas bypass valve back here on the back that was dumping hot gas into the evaporator. This is water cooled on top of that. So it basically is a pump and dump. It dumps city water or well water I forget which one it is into the condenser coil there. The head pressure control valve here controls it based off a discharge which is down there on that liquid line. The last one I worked on the motor was bad so that was pretty easy. That's working so I stopped the flow air flow so that we can maybe look for a refrigerant leak. I guess recently we had the pop off valve back air pop off right there and essentially what that means on some of the bigger systems is they will blow the refrigerant charge. Now you gotta remember this is probably way before all the environmental stuff. This nightmare is 460 volts. We got the strata spray to go warmed up. I did see oil up here. Did find some leaking here on the valve there. That had popped off I guess like I said earlier possibly that had blown off earlier this year when the pressure switch failed to shut it down. So we get it on the super position. If I go to the parts per million usually that tells me if it's just an accumulation of something there and it went up to like 15 a little bit ago. Now the unit is off and there was something in there so when it's running with a couple hundred pounds of pressure I'd be curious to see how bad it's leaking. Now that could get a cap on it which would be potentially dangerous but don't know exactly what we need to do on that. It should be replaced but then you have to recover the whole system. We may have to put a cap on it until we can get back. I really don't know at this point but so far I've scanned all of the little capillary tubes and all these little valves back here in the back and for the most part everything looks pretty good. Nothing leaking off the discharge, suction anything like that and that's on my highest setting. Uh oh there we go. There we go. Got something there. Let's go to parts per million and see what we get. That's a pretty good size leak. That is a very good size leak. Cap would be kind of nice on that. Always should be checking in your regular mode here. Super mode, high mode whatever. PPM is not fast reacting. It's not made to be reacting. Did speak with Infacon at the AHR show and they did say that it does take uh 10 to 15 minutes to get the best performance out of this which I did not believe but I drilled and drilled and drilled and they're claiming yes. It does better as it gets warmer and even Clayton our other guy that I uh he's got the same one says he notices the same thing. I have not up until recently so the battery life on this is crazy long anyway. Yeah see there's a little bit there on that so we got a little bit of a leak there and we got a big leak on this one. All right let's go ahead and spray that. That is the only other thing other than the evaporator which I already was told leaks. Got the big blue here. See what it does. Oh my gosh look at that. See if we can get solid stream that's the way I like to do it. Look at that. That is a good size leak and that was running high pressure a little bit ago. Yes sir. Not good. All right so that is really warm from the boiler coil up above running. I did find the cap down here on the ground so we're going to put some nylog on that thing and crank it down and see how it does. So we got the nylog on there on the threads all over. Got a wrench on there going to tighten her up just touch and let's see how this does. See what we get on super mode here. Very little. Like I said there's a little that valve is actually hot. Three parts per million. Could be residual. Could be from the nylog possibly but not seeing any leak. But I tell you what that definitely would have done it. All right so let's see the air conditioning coil looks like it's right there. Fears that kind of goes up in here. That's a thick metal too. But like I said here's some of the dampers open and close. Got two different ducts going out and I'm pretty sure that might be the difference. One's hot one's cold but you can see they went over there. I don't think that's returned because the return's coming into the back side. Yeah yep so you can see here you've got one it's going to be cold and one it's going to be hot. You got your steam boiler lines right there. I don't know how big that coil is so I can't really just drill in there. I can maybe drill a hole into here in the duct just to see if I got something big going on. All right so I was correct you can see that top area there comes across there is the uh lines for the boiler and you can see right here is the fan. It's a fan blades going to be in here turning it's going to come through up through that area and it's going to go through that area there. The two ducts are going to be straight on out so the dampers are going to be out in the office area from what I've been told very similar to a VAV. You can see we've got a little leaking there's an actuator right there. Let's go ahead I'm trying to get my last scanning done here which I picked up on something a little bit back here yeah and I'm picking up a lot over here but I need to get inside there for a good uh yeah this is so super super safe it's a great setup quite the interesting venture. So what I worked on the last time was that motor up there you can see it's a newer one a little bit easier to get to sort of all right so what we ended up doing since this is the thinnest metal I was going to try to do it here but way too difficult so we went ahead and drilled a hole we're coming in there on our most sensitive mode scanning around I'm not getting anything we're looking for huge leaks here we already know that it leaks supposedly in that coil from what I'm hearing from some of the other guys that had been here I can feel that hitting the top so there is definitely a divider between there I'm not getting anything this thing is leaked on a routine basis and you just can't get them to replace it because this obviously is going to be super expensive and very difficult to get in here you've got so much stuff in the warehouse here in the way whatever excuse you want to say whatever it's their money so whatever so we got everything hooked up bled out we did have pressure on it which is good so let's go over here get this thing turned back on I did not want to turn it on ahead of time and have a potential of it being in a negative and then sucking air and not that this thing's probably working the greatest in the world but there we go just like brand new somebody asked me again what this was it was the mb5 b mb5 b so veto so far I really like it it's getting a little dirty but you know that's going to happen no nowhere or anything like that everything's working pretty good in there got my probes in there got my probes for refrigerant and like vacuum okay surprisingly we got a little bit uh we're on a 30 degree evaporator on r22 yeah we're really mainly just vapor down there and that so let's go ahead and slowly add it because we are dumping it right into the suction port we are doing in liquid but we're going to modulate it in slow we're going to watch our weight scale to see about how fast we're doing it now I did bump it so it is wirelessly transmitting over here to the test though this is the 557 which is their best model I got it because I had better luck with the older 557 not so much because it has a four port manifold but I did get it because the transducer seemed like it was better on the old one now on this newer one I don't know how the newer 5550s are so I got a little scratch on there but other than it wiped off there the 557 that's the model it is you can tell because it's a four port as always check out true tech tools save yourself eight percent with discount code survival but yeah starting to get a little bit of flashing that's good so hopefully we'll get get up there fairly soon we'll be able to maybe check some sub cooling and stuff see where we're at on that 1.6 degrees sub cooling so far four pounds starting to get some flow through there hard to see it but it is so why are that's adding slowly I wouldn't normally walk away from it we'll start skiing it for leaks while it's under pressure you know under high pressure yeah that's your economizer for outside air I believe here's the outside coming in and then this is going to be a return coming in and depending on which one it is they pick which looks like to me oh wow yeah that made a difference I could hear the fan start to crank having a heck of a time yeah you can see the ducts suck in so it's sucking outside air in there yep there's your filters there's your big ass blower so there's your outside air it's got one one open there because it's broke which is nice and then you can see here the other half so when you flip that up you can see that's outside air I don't know if they did on purpose or not kind of makes me think they probably did I think it's kind of scary is could be freezing up a coil if things went down it kind of makes it simple enough so let's go ahead and just kind of ready to see here see if that pop off there oh wow we're already leaking something fierce that's great go to high that's great go to low that's great so I don't know if I'm leaking on that could be leaking on my valve okay we're at eight pounds let's go ahead and stop adding we could either go to parts per million see how bad we're what we're going on crap look how bad that is okay there are the 200s up top geez man that's the last thing I need is this crap see how it kind of comes in handy so one thing I learned at the AHR was that the manual zero which is what I've got it in now where you basically hit the zero button allows you to narrow it down so you get close like now and you zero it knocks it down to nothing this gives you more range all the way up to something really high hit it again there just went down again then what the parts per million mode even does so what I think I got remember when I originally said that the suction port there looked pretty bad so I get over here hit zero keep getting closer hit zero I get right up on that bad boy and she goes berserker so we can go over here to parts per million we're already in the 190s this is going to get stupid I'm sure should be right up to the nine thousands yeah five thousand area I've been skiing in my sight glass nowhere near the level I thought maybe I had something leaking on my hoses even back here on that valve that I had before all in the 90s stuff like that which is residual you get up here though and even up on top I'm not really getting nothing stupid and my hoses not bad get down here where oil was at and that's where she goes nuts so let's go ahead and yeah they're four thousand let's go ahead and squirt it it probably blow it right off my hope is I can just tighten the bolts up we'll see it's kind of crazy I don't know if we're leaking on that service valve does not appear to be unless we're leaking on all this garbage back here so I just re-scanned it again and it does appear that we have bubbles forming right here you can see it micro bubbles it's such a big area all the way around there that that's likely distributing it all the way around I'm going to go grab a rich socket and see if we can tighten that thing up and then if not we'll have to order a seal for it must be just a 16th under maybe a 15 16th or something because the one inch was a little bit big but it fit three uh half inch drive I was going to use my three eighths torque wrench here which I don't have a half inch on the truck usually three eighths does most everything well anyhow I was able to get maybe a I don't know not a lot a lot a lot I maybe about that much swing if I'm lucky and it appears it may have worked so when I come up here now and I just leave it there I'm getting one to zero we were way higher than that earlier as you seen earlier may have gotten it we'll see I'm going to scan it all over again but it sure seems like we've slowed it down tremendously if that's the case which is great if so yeah we're getting a little bit around that packing nut there which I've got a cap down there that might fit it I don't think it will but I haven't tightened that packing at all whereas before we were leaking bad on that suction which I hate having to use uh king valves to open and close myself I prefer to have a straighter core built right into the copper any day over this crap because all you're doing is you got big wrenches you got to get out it's more of a hassle I don't like it uh anytime I get a chance to add one I will so we're going to go back to just high see what's going on take her away because I mean it will automatically lock out if it's a bad enough leak we're still liquidy and I got 21 pounds in there like I said it holds 38 cap there I didn't uh there's the suction one right here not sure why all these didn't get put back on somebody must have forgot the water overfills goes down to this uh spouting and the spouting goes down to a drain you can see we're starting to get decent liquid rolling through yeah you got decent liquid flowing through there and we're starting to get a little sub cooling um I'm surprised it worked it may start leaking again honestly they really need to make a decision what they're going to do because our 22 is not going to be available at all once it's gone it's gone so it's uh silly but a couple grants cheaper than lots and lots of grams so I have no clue what these cost but I guarantee you it's not cheap and those are the people in the UK and all the other foreign countries yes you can use it yes you can put it in a leaking system depends on how many pounds it holds it's under 50 pounds so yeah don't need to hear it it's not fair wha wha wha you know what your climate pair is accord and all that bull crap that's the reason why it is the way it is if you don't like it then change who you vote for even though they got everybody indoctrinated now all right we are solid and we have three degrees of sub cooling you can kind of hear unloading every so often see the oil down there still I think we'll stop right here at the four pound mark that puts us at 25 pounds there's no receiver on this so we don't want to go stupid so therefore theoretically you can't even charge by the side glass that's why we double checked it all against the sub cooling that compressor's rebuilt already you can see it says good as new must be referring to it been changed we'll watch it for a bit see if it starts flashing off but yeah I think we got it I know we can feel cold air coming out of our hole here which feels pretty darn good put a piece of tape over that here in a second let's go over here and look at that display and see if that temperature gauge is reading a little more accurate now cold deck running 40 42 degrees not bad that cold deck is running 43 so see the 41 or 42 actually I probably bet you it's two so 42 and this one here is running 246 46 hot deck on both of them that one's running 140 that one's running 120 return air temperature is 78 it's going up and down huh all over the place okay let's go ahead and scan that over that was our biggest one that originally does not appear to be going off we can try it on super which is pretty extreme nothing back onto that pop off nothing threads nothing I think what was happening is it was falling off the back side okay that's on super nothing nothing on that thing going on wow I'm going to say I got it I'm surprised I didn't figure it work and it may not work when it's all sudden done but as of right now it is working I'm not going to fit on it I think we're good obviously there's a little bit there on that service valve that's open but nothing nothing on that that seal there we are still solid we got three degrees of subcooling I'm going to write these numbers down so I have something to remember next time all right guys that's going to wrap this one up hope you enjoyed the video all right guys that's going to wrap this one up hope you enjoyed the video if you did give it a like give it a share keep subscribing click the notification
