 and here we go we've got a bunch of things down so I'm thinking we got a leak we're just gonna look for something big all right so the next day we got them both going both out here clicking away here's the old H10 you guys want to see this it's workout Dave this is gonna hurt buddy hold on a second this is gonna hurt a little bit we are on our most sensitive we'll even go up to the highest tick tick we'll get just below green watch this this video is brought to you in part by TrueTech tools quality tools essential support all right so we've got us a grocery store that's not working very well supposedly it's up to 50 to 60 degrees which generally means nobody was watching possible alarms so let's go in here and see what we can find out alright so we just climbed up here and here we go we've got a bunch of things down so I'm thinking we got a leak a8 is working but a7 is not and then the only case here is not doing well I think she told me produce too so that's all on a this is a press is running press is running press is running press is running click the levels nothing that's at zero quite a bit of disturbances there I just came out of a deep Ross we got a hot gas deep Ross going on all right let's go ahead and get this thing juiced up a little bit that go grab the long hose because I'm not run that thing up here yeah everything's on I changed one of the deep Ross clocks which these are all working I doubt they're all going into deep Ross same time as you see they're all staggered let's get this turned on and calibrate it outside here all right we're zeroed out hopefully don't go off oh boy so they've got that already blanked it off just do a little coast along here if it's a real leak we're gonna maybe picking up something we're just gonna look for something big the way we don't dump it in there right away have problems got a rubber seal in there works pretty good now we'll leave this hose out to the outside so I say I want false alarms we're just bleeding out the air yep got it been trying out these crescents they've been pretty good I like the side cutters and the lines have been pretty good he's got a nice end on them that rips right a hold of a cap you can see you can't hardly get in here with your bare hand you'd think they'd put a suction port on the suction manifold but there's one there but it's more hassle and it's worth the screw with there we go let her eat and then we'll dump the other side into another port here take your pick I picked this one because it was so warm I wanted to make sure it was going to be on for a while and we'll start dumping in there too we're gonna go ahead and start scanning the rack see if we got anything going on here in the rack area unfortunately we got nothing so far we'll check up here on the up on the roof and see if there's anything up there I'm in PPM mode which usually is not the fastest thing in the world it's not as fast as super or any of those so we can go ahead and do more of the super mode I've had a lot of leaks on these uni struts the idiots put them on and didn't put clamps on all of them now these ones here look like they all have clamps but they don't they'll rub right through and eat right through it I mean you should figure it's gonna be a decent size league something I should be able to pick up pretty easy I just went ahead and scanned over all this here here all the manifolds briefly underside it is really windy out here our fans are not even running but I went through all the different ports on the side of the condenser through all that if it was a monster leak you would probably see some oil up here on the roof I see nothing out here now something that's kind of bothersome they said that bakery freezer which is on the B circuit not the A circuit or rack the wrong rack that's on this one so unfortunately we might be having some problems that like I said the level in this thing is really pretty high yeah this one here it's just finally maybe 5% see even with 5% still have still have a sight glass that looks like that all bubblies or 90 pounds pressure you see that's why I like the sight glass you can see what's coming through the heat reclaim comes off a heat reclaim valve right here so it can either go one or the other then it'll come back and then finish out on it but comes out goes to that wall it's gonna go over there to that air handler alright so we're inside the air handler that line comes on through that side I just scanned all this coil in here I do not see any oil anywhere in here so the lines coming right through there like I said we went through there it's being pulled that direction so it'd be pulled away from me but if we lost a hundred pounds not granted it was pretty low begin with so it ain't probably a full hundred that just happened like today but it's gonna go that direction and we should be picking it up in the store and I'm going to and I'm still not getting anything yet everything's working fine in here we've already scanned this room and that one over there these things always leak I picked up something in here went to the PPM scale and of course it's not gonna do it now they turned the camera on while you're definitely low I got itty bitty hit on this one I didn't get anything big enough to lose a hundred pounds or more I mean I got at least I was on the roof already and I looked at the reclaim and it seems like it's nothing over that either I don't see no oil anywhere so I mean it's like when the whole it basically the whole systems low so everything gets starved so what whoever's the last on the loop is the first one to get starved out of refrigerant then they get warm but I mean it wasn't that high when I was here last week either that's not uncommon they don't like to put too much in it because if it does leak then it's all that extra for no good reason all that frozen and right here this section right there is all on the pink and the pink comes back to be in B B actually has a pretty good level this is still warm the A14 which is what I was originally working on that was low so 14 it's coming back cold still pretty low not even really moving so we're gonna go ahead and tie on to another one let's get this thing up and go and I got to do something so right there is my pet brush it's one of the used to have one of those little push buttons I ripped that off these are pretty well planted in there but that works really good to get evaporators clean we just cleaned the evaporator off in the walk-in the battery went dead I'll show you that here in a second these coolers right here we just cleaned up got the backs cleaned up there a lot better what they were here's what we got out of it off the back of it all right so the rotary clocks here connect to this plastic thing and I changed this clock the other day and used the one that was with it while it ended up breaking off that basically like two fingers put it onto a flat surface and it rotates them it's working they're all out of defrost almost all of them you actually see a refrigerant level there 20% whoo-hoo but come up the top I think the easiest way to see what's going on you can see there's a black lever that's gonna snap backwards and that's going to put it in the defrost we're at 10% right now so heat reclaim is technically locked out which it ain't sending none over that direction anyhow we just lost 10% again dang it what we're gonna need to do is come back tomorrow follow these lines across the ceilings I'm not getting anything in the case is on this rack I got up and double-check some of that area over there and didn't get nothing on that basically there's not a whole lot more I can do tonight I'm not staying here all night it's almost seven o'clock hold one of them out of defrost that was just recently gone into defrost because it was see there's 30% that's what sucks you can go from zero to 30 that easy all right so the next day we've got them both going both out here clicking away got my power top there for when this H10 Pro goes dead which will probably be in a half hour at least while battery power I want to see if we get anything as we come through the door I mean I've done a million tests on these two and for the most part usually Stratus does really good on everything so what we did we're shutting down the deli and VNZs are pretty much controlled only by the suction stop and mainly the EPR valve the PR valve mainly regulates it there is no liquid solenoid on this thing we're gonna stop it that's gonna allow the refrigerant to come through the valve and the TXV come back to here and it's gonna stop it's gonna build suction pressure and we'll be all recheck it I only have two that have hot gas defrost which is circuits 10 and 9 when I put those in hot gas defrost that's gonna allow me to get a lot of pressure out there in the evaporator heat reclaim lockout happens anytime this goes down to zero I don't know a lot about the CPC control these things were installed in 1987 top left one so yeah this thing's just a couple years old that's the kind of electronic you can actually fix the old capacitor still going you won't see none today's technology last that long but you know we were at zero just a little bit ago we were at 40 now we was back to 30 it's just all over the place the H10 is already dead so we're gonna plug that in just gonna put that on the side of my belt right there and like I said we're gonna see if we can find a stupid we've only got time for this crap so now that we've outed off that pressure should be built up pretty good in that delicacy all right we may be into something here this whole row I went ahead and shut both suction stops there's two circuits coming into the air band look at that now look how that's pegging out in super mode didn't have that earlier here's the old H10 you guys want to see this it's gonna hurt it's gonna hurt or Cal Dave this is gonna hurt buddy hold on a second this is gonna hurt a little bit we are on our most sensitive because that's how I run my detector all the time we'll even go up to the highest tick tick we'll get just below green watch this same spot oh wow we got a little bitty bitty bit and we are we've been running nonstop for about an hour now we got a little bitty bit look how long it's taken yep back away from the H10s the new song bud back away back away from the H10 see we get a little something there but see if you're crawling along whoever comes along goes I'm gonna go slow yeah more like it most people are so impatient they're gonna come along go huh oh look at that oh wow whoa hardy cow oh yeah look at that we're getting it down here even yep crazy and what kind of parts per million are we at here let's find out here oh it's 25 it's over this way and a H10 couldn't tell me that yeah even at high it's getting it here is medium medium it's not getting it so you need to learn your detector what's it take to make this thing go off okay mediums not getting it only in high all right so we found no other leaks except for right here so it's gonna get this thing opened up unfortunately I'm having a bad feeling this is gonna be up in the coil you get this fans run in there it's not gonna help yeah that's what the fan off let's go to parts per million this ain't gonna be good oh boy look at that 205 so it's got to be right during that second one see how to start to climb up we're gonna have to pull that panel there have them remove some orange juice see if we can get away with not removing the shelf see if I can fix it in place if not off to yank the coil out we're gonna have to shut down this whole section here most of it's pretty resilient all right so we got it open coming in we're on low get down here in low and unfortunately it's going down off there it's not going off here I don't have my superior acutrack with me so that somebody borrow it yeah it's here and something I wish I gooseneck because I could get in there tighter it's going to get the headphones on so we can hear actually what it sounds like I'm not getting like I was earlier using even the nozzle on the end I can hear a little bit going through the TXV there that's about it so we're going to spray and pray picking stuff up in the middle here but it may be bleeding down I mean this stuff is 30 plus years old oh yeah there we go now daddy's getting a little happiness look at that 9th out 900 I was able to pull it out a little bit I'm going to cut it right here unscrew it here after I drain this circuit all back to the rack I'm gonna pull it out and hopefully be able to fix it in place because this thing's probably not real light and I have no one other than maybe some stock boys to help and honestly I don't take a chance of them damaging it worse I'm already a little bit worried about this here coming through that that may end up leaking when we're done you can tell this here's been pushed down which put more torque on those fittings we got a little more of the bleak blue you never need that torches I think it was three-quarter inch we'll know here in a minute got a flare plug should be able to plug that TXV off for the pressurization so we got that looks like I got that one there too just pump this turkey down now what we want to do want to go in there we want to shut that circuit 8 off here at the liquid valve should use your refrigeration wrench most likely not bad we're open there and then when we get down we'll valve off our sort valve SORIT sort valve so we can do they come in here turn off some of these other circuits so there's our suction dropping we don't get too berserker just yet we want to get that suction down I was able to get it down force it down about five pounds maybe had a force one compressor to run slowly bringing it back on because I don't want to just hammer out all these fans on top are obviously all tied directly to power contactors only the smallest ones in so we're gonna bring in one circuit at a time so that pressure starts to drop then they hopefully the other compressors will start to kick on here I did reset it was an alarm cookies that'll work pretty nice so now we got to get the nitrogen out and see what we got to fix that is beautiful warm that up that way it will bend easy put this on the end the very end here I don't want to gum up my stuff too much I only just want to get it on there so we can do a pressure test on it that's all I want we're not worrying about nitrogen on something like this right here you you don't run nitrogen on a rack unless you absolutely are doing a full-blown galore thing you'll cause more issues if you contaminate several hundreds of pounds of night refrigerant with nitrogen and what you will get a little carbon on one of the screens just because it's bigger don't mean it's okay but what it does mean is don't be an idiot and create some major issues take it for what it's worth do what you want I've I've done 20 pounds refrigerant contaminated by accident that's enough to make me not to get too stupid on certain types of jobs so let's get pressurized and we'll that way we can see where we're at there's another we got multiples end up rebuilding this whole stupid coil on so sudden don't right there that one there's definitely the mouth breather have a group so what I do on that we'll know that's one of them we know that I know every one of these here are leaking so we're just gonna do all of them on those I it's gonna be a bear to get in there to get those that one right there's leaking really right on the end of it not granted they're never gonna have over a hundred pounds on this coil this is not hot gas but that's the bad boy right there or is anything leaking on the backside I hope it ain't we're gonna spray it as best we can they seem like they you know did a pretty good job on building these back in the day compared to the junk we got today hope is that you can get that heat in there I don't know see what's going on on the other side you need to be able to get in here and you can't do it very good when you're fighting all this product is right beside you we're going to warm up a little bit right down to the bottom or into the inside a little bit two and three I'm going to bend this back because I don't want to break the leaks I'll be able to find out on this pressure test any of my tools are down in the links below I don't see anything out of that one that's what I want to know before I waste a bunch of a bunch of nitrogen I only got two of these tanks in my truck make sure not these other ones started leaking because we missed with them hundred and eighty five pounds didn't mean for it to go that high I didn't want to create a leak it was an accident but guess what we are not leaking granite lasted that long but you can see I helped my dad was a welder and he taught me the basics of how to apply your heat and how to make a good weld he didn't do much brazing but he did build a M1A1 and M1A2 tank so you know I think you might know a little something about making good welds you won't believe this but we got another one right there itty bitty stupid piece of junk I want a piece of crap that is beautiful oh my goodness that is beautiful I could never do something like that with a bigger tip that makes so much control it's so so nice pretty handy there got all the inside that crevice real pretty light yep somebody already did a repair on that look at that little scab job there he did one there's another scab job look at that there's been some repairs on this already wants you know all these could have used it but I am a little bit afraid of creating more leaks on what I fix good spray this in here make sure we're okay here coil box I do keep brushes to try to get any carbon out of their wild can you know you'll get that out now before we do the other side so any little bits that we got in there we got it out inside the pipe a little less likely to have happened but it can with the nitrogen being purged through it it's gonna just place the oxygen right here by the thing by the edge you're gonna get oxygen what's going on in there all right so we're gonna go ahead get this thing pulled down at the big blue hose on there we broke that backing with the suction there brought it up to maybe 15 pounds of pressure named took that valve core tool off because they didn't want to come off it was too tight back to 20% heat reclaimed back to working here we go well good thing I double-checked it the detector went off leaking on that flare not there I'll say the least went ahead and pumped it down got that freaking thing cut out and we're gonna try to make that thing braze back on to it without screw with the brasses right beside it it's not fun too dark to get a good picture but use those again I think we got it okay I'm cleaning the face of that flare with a scouring pad here to soften up any edges that might be messed up from the old flare I can't figure out why it didn't seal it should have but whatever it's starting to freeze on there unfortunately but it's it's it's enough there that it would definitely bubble really lucky I mean we only had a step about that much and yeah that's pre-made flare made a lot easier and I don't usually like using them but it's nearing like this you'd have to swedge it flare it get it not screw that all right guys if you enjoyed the video hopefully you did more than what I did doing it leave a comment or thumb $20 whatever so until next time catch you on the next one later
