Have some fun out here we're out behind the shop where all the bad kids hang out and that's kind of what we're doing now? We're going to be messing with the system, which is actually cooling the building inside where there is a classroom currently, and we just don't care because we want to have some fun. So that's what we're doing right now and you guys are going to join us. It's going to be a long video, so hang out see what happens so i just wanted to ask this is all your idea, so why? What? What are you wanting to figure out here? What are you trying to prove to yourself? I wanted to see this in a real world application. We've been running it all day for the last two days on a coil that simulates a five ton unit.

The two cfm has worked wonderfully on that coil lasted multiple pull downs on that coil on a single battery pack, no charging of the battery, except for initial, and it's done wonderful on what would be considered a dry system, in my opinion, as a technician to relate That to a system that's got some oil, it might have moisture in it. This unit's been open multiple times in training um. So i'd like to see it in more of a average situation for my tech in the field. Okay, so that's what we're going to represent here today, so what's our process, what are we going to do we're going to go ahead and recover all the refrigerant out of the system? We are going to open it briefly to the outside air and then we are going to go ahead and put on our 2cfm battery powered and battery-powered navec pump and um.

We are going to start an evacuation and we are going to see how long it takes to get down to a vacuum. So you're going to pull a vacuum on the whole whole compressor all right, all right. Let's get this started as soon as possible and we'll keep chatting afterwards andrew tell us what this recovery machine is. They just have an automatic shut off.

There's a couple options there for that. You can program uh for different different levels of vacuum. You can have it behave differently, you can have it alert you with an audible alarm. You can have it automatically kick off for you.

If you're not there, there's a couple different options in the manual and you can select, which you know would be your preference all right yeah. So this is our nrdc program again, you know who's with the guys here a few minutes ago. This is a little bit of a mismatched application. This is a dual compressor: four-cylinder three-fan recovery machine with application intentions.

You know in the heavy commercial, maybe industrial space, chillers large rooftop equipment, brm - something like that so yeah, so we just walked by some of the boosted displays out here and we're just grabbing stuff off the shelf, and he was nice enough to let us use his Stuff to kind of demonstrate: oh yeah, it's going to be off the unit, so yeah yeah uh. Well, it's kind of a neat juxtaposition right, so we've got kind of our monster here with our baby yeah yeah. Let's see we'll see how that works out. Maybe it all evens out yeah, i don't know i love it.

We've already pulled out four and a half pounds of refrigerant and we're nearing the vapor phase of the refrigerant. Now, all right, four and a half pounds out yeah, you can hear it. How many seconds are we into this? Is it going to the live, yeah um, three minutes and 43 seconds? 4. 13.

6.. So we're at like five pounds, pretty pretty right away, and so we actually have a micro gauge on our pump that we're going to show you we're going to test this thing first and so we're going to turn it on and that's how we're going to check Our oil and if it pulls down to what the vacuum's rated for we got clean oil, and this has been used a couple times already today - the oil, that's in it, the vacuum, so we're going to see if it pulls down to. I think it's rated for 20 microns yeah, if it pulls down below that i don't think 26 looks like. Then we got clean oil and we're going to keep going everything's going good.

I think that's something that's going to make more sense in its intended application. I think here it's probably not going to have much trouble right on you guys know what you had charged in here. You should have coming out uh. We should have what's listed on the data tag.

It says five. Six, we stalled it. Okay, okay, all right! Did you actually shut the valve right just curious all right, would you tell us if you did no no yeah? Last year we opened this up and put a little ball valve, so you can simulate a restriction. He threatened to shut that down and seal half of our system off just to make this harder.

While we're going live, yeah well, how's the weight, did it look close to what the data player had close he's off by about six ounces? Now let me see if i got a nice line, because you want to make sure you have everything out of the bottom of that accumulator and your pressure starts coming back up if you've pulled down and it's frozen down, there you're still going to have that liquid. In the bottom of the accumulator, that's going to boil out a little bit longer: oh yeah, there's a little bit of frost down there. You might go a little longer. Save yourself, some trouble is it well.

It will show zero, sometimes right here at this port. You have a little bit more pressure on your system and then further back in where you have liquid. It's still boiling off at that point, and also it's just kind of fun running that can we get a little uh camera showing the camera here please on the live stream. If we can look into each other's eyes here we're doing good on time going on wow.

That's beautiful, that's a rare moment. Yeah, i'm glad we captured that that's important yeah. That was a sensitive moment. Does anybody around here want to talk about how they felt right there? I want to know how many people are watching this on youtube right now, if you guys could all pull out your phones and log into youtube and watch this, so we have an audience that would be.

That would be important. I want to see some comments yeah as long as i'm in there it's live youtube. You can see yourself on tv right now we're pretty much locked at that four pounds: 14 ounce mark yeah. I, like i like to see minus 14 psi yep, so we're already pulling it back in so we don't even need the backhand yeah, so mine will go down to -20 and start beeping at me.

Be like hello. You can do the purge now and i'll switch. It over into purge and you've got 32 people watching all right. I got an audience, that's what i like.

So i like to hear it's going to be fun how's that a cumulative, so anybody that's just joining us. We are going to be actually testing the 2cfm battery-powered navac vacuum in a real system, real application. Let's imagine we're replacing a compressor and we got to recover the whole system. We got a unit here, it's our training unit, so it has been opened up lots of times and we've had.

You know liquid, probably in here we might even have liquid in our oil, which would be a problem we'll find out when we start to pull a vacuum on this um, so real life application. What how's this 2cfm gon na you know hold up battery powered. So probably do your purge now 14-6 and then what you do here. So what you'll do is turn it down into purge and push start again and that'll.

Take everything that's sitting in here and you'll watch your scale, suddenly you're going to start moving stuff out of the coil, and it's in the compressor. Now we're now we're at our weight. Yeah! That's that's where the rest of that was hiding, and then you just let it run out of there. Let it run until it stops itself.

So this thing holds a decent amount of refrigerant. Inside of it yep, you got, you got compressor the larger the compressor coil, the better job. This thing is going to do so plan on testing that nice we got to verify all our components are working, how they need to before we use them. I'm happy with that.

Let's see if bryce checks the world out before we i'm going to show you better. Not now hey do a little uh walk around show some of the stars that are standing in the audience we got. We got some good stars yeah right over there. Zach he's already he's got his camera out.

Maybe you guys you guys, might actually see something for sure. Look, good, okay, good camera and some people just don't need me. What happened? Did you test it? I'm about to? No, i mean the pump i'm about to oh, okay, all right, you should be good, so the next thing. What are you going to do next next thing? We're going to do is we're just going to go ahead and make sure our vacuum pump.

Oil is good which we looked at, but visually inspecting it's not going to make much of a difference, we're going to pull a vacuum on our pump to make sure it comes down to the rated on the name plate nameplate on this pump's 23 micron. So we're going to make sure that we can achieve 23 microns at the pump. Do you have a vacuum hose out here, yet uh we're going to use the blue ones up top? Oh, you already got them. Okay, all right, so how's our! So as we pull the vacuum on the pump, we just want to make sure that we come to at least the rating on the name plate, which is 23 microns for this particular pump.

So right now it's pulling on your fittings, any moisture absorbed into the rubber seals and our gauge that has been sitting on a display table all day, open yep. So right now i never doubted you for a second. You know i just had to feel it myself. You had to make sure okay, let's get the vacuum set up, so we used, so i can pass it to people like you yeah.

What do you have to say for what's going on here? Hey um! This works really good. If you go like this, oh wrong way, it's like this. Oh we have a new star, all right, yeah uh-huh. I think i should.

I think i should start a youtube channel. Oh, that's, not a bad idea! You look good on camera. Your voice stinks, but you look good on camera. He thinks i should clip this on right on.

It doesn't really feel real right now it does. It feels more like impressive. If i'm holding my two fingers like what the heck is that thing we're going to go ahead and put on these blue vac hoses, so we're going to do this right, i don't think you have a tee you planning on using them both. Oh you do that.

One will take both okay, all right, sorry, jim and i'd say we're within the margin of error just kind of casually observing. Oh, i need the yeah. Oh yeah, okay, yep, we've pulled down. Yeah i mean if we need to change the oil we'll we'll change the oil.

If you think, if you want to change it over two microns, no, i'm going back to the booth. Okay, all right, we're good! Then here's somebody watching the movie show the status on our sorry yeah. So we've pulled down within two microns of what it's rated for. So i'm happy this vacuum's ready to go and actually no i'm still.

Let's see that one's good, we'll just put that no we'll just put the gauge on the end here, yeah the when you walked away next thing, you knew two hoses came out. They were so excited to use the hoses, we're going to hook two of these giant hoses to that 2cfm vacuum yeah, it's america! We want right all right. What do you charge a customer, a whip that you've made out of a vacuum hose? I'm just gon na charge you an extra 200 for this whip out of vacuum. Hose out of vacuum did not hit that button nice.

I love this. This is so fun. I'm glad you did this. This is the complication.

He warned me about yeah bryce said before i decide. I want to buy something like this. I want to take it off of a dry coil that was set up for display and use it like. I would in the field all right and our vacuum gauge.

Oh, you have a t over there. We need to cap that yeah so maybe use the t using the instead yeah. Well, you won't be able to do this. Okay right, my bad, my bad man there's some there's some good voices over here.

Chiming in it's not good, because we got too many people here, hey back there paying enough attention to one thing at a time, just like a customer standing over here. I know look at that camera! That's when you zap yourself and you do stuff wrong and like make an idiot yourself when you're someone's standing over your shoulder, that's normal! You want to stay for more that one ran out of batteries all right, so we're going to go ahead and turn on our blue back. Can you hear me when i whisper to you austin, i'm going to whisper instructions live whispering because you're whispering straight in the mic yeah. Why am i holding the mic so close when i whisper whoa? What's this? What's this we're gon na go ahead and use our blue vac app to monitor our vacuum gauge holy cow? These people are going all out.

What are you guys charging a customer for all this stuff? I mean it cost us 200 yeah, okay, each we're charging per man hour out here. So every technician out here all right, so we're going to go ahead and start our vacuum. This is a big building boom. It's on someone marked the time.

Okay, talk about timing, uh; no, we recovered so that the whole system back in huh - and we got like an old oil in there and everything our vacuum gauge is leaking, didn't seem like it was depressing schrader. Okay, it'll take a little while it takes a second and then kicks right in and starts see. If you watch this, it was doing something it usually takes about 60 seconds before, depending on the size, your system, before high pressure, is going to go out. The entire system right now yeah, so we're pulling on the compressor yeah full of that peo oil that has there we go probably moisture in there from how much crap this unit's been through yeah.

We do need to start the timeover. We have a timer based on the back as well. Are you getting paid for this um? Not enough, actually, no more more than enough all right right now, he probably is watching his head. Yes, so we've been running our vacuum for roughly two minutes so far.

Okay, boom we're below 25. starting to pull down. That's why i'm doing what i'm doing right now, all right, so anybody who's joining the live stream. A little bit later, uh bryce wanted to test the vacuum on a real system like as if he was replacing a compressor on an old unit and this one's been through so much trouble.

So we recovered everything from the whole system and then just now started the vacuum and take a look at the vacuum. This is our 2cfm battery-powered vacuum that we've hooked up to this unit, so he wants to see real-life application. Is this going to work? It looks like it's not going to work now mind you. Our battery time is proposed to be one hour on the standard battery that comes with this two cfm right now we have it on a nine amp hour battery, which can achieve up to two hours of runtime, mind you.

We are at less than four minutes of runtime on this vacuum and we're under 5000 microns we're currently dropping about 55 microns, a second um, not this one. This one does not um they're higher versions who gave me these hoses and why am i holding them? Um andrew baby, those poses they can go back on the neck. Okay, i need two competitors. We are going to do a hose fight who's up for this.

You you're holding the camera somebody you can beat on him. Try not to hit the camera. We need some entertainment, there's no cap in the other end of that right there. It's all you ac, nerds, caring about caps and open ends, good grief.

What do you do? Tape your copper ends after you cut it four and a half minutes 3000 microns. This is what i do for all my trainees, and i understand this is not a training moment, but you just once you've done this long enough and had so many problems. You can't trust anybody else ever ever again with a single connection ever so no offense bryce. All offense taken yeah, that's what i wanted to hear.

Okay, so now we're gon na have another fight. Hoses there's been a lot! Oh yeah! We got a fried lizard in there nice and that it's probably still live. Does anybody want to pull it? Yes remind everyone? It is live so go ahead and pull the disconnect. Oh no, it's not live you're safe.

It is not live okay. So where would you like this as far as like good camera shot, i feel like he needs to be remembered. This is the kind of thing that is pretty sad. You never really see it in real life and uh.

Here we are here. We are in a moment like this capturing something that's you know once in a lifetime sort of thing that happens so we're just gon na remember we're gon na bury that hbac burial touched it, and now it's climbing yeah you're right did i mess it up. I think he touched it and touched it. Ah, i did touch it.

Can you not tell anyone about what happened? I did touch it. Sorry. That means we're doing some work yeah. No, that would have been a good idea yeah.

What are you saying if you do that right now, i don't know yeah, maybe not, maybe not so. This is a trainer right. Yeah, there's going to be a lot of moisture in this system. Yeah.

The problem is the ice ring on the bottom of the accumulator. We never really purged it with nitrogen before we uh hooked up our vacuum, so we could be starting to boil some of that out. I'm gon na leave since i messed up the fittings there we go now we're coming back down was engaged until i pulled the wire from hit him with a stick. We had a brief moment of some gasses flashing off from the accumulator.

It also might be an application where it would have been better for us to purge with nitrogen or even to do that again and start restart a vacuum. So we might end up doing that if, if this doesn't keep dropping - and this is a real world application for text - because how many of your techs are going to actually on every job sweep it with nitrogen yeah, especially some of your more rookie techs. No, this is a good example or your nitrogen is sitting here yeah if you're sitting here watching a vacuum like this, it might be because you're pulling on an accumulator that still has. It still has something on it and been a good idea with nitrogen being 410.

It is hydroscopic it's gon na hold moisture in the oils. Yeah, as our lovely jim bergman, told us that um you don't get that moisture all out. I love everybody. I think he's done 400 phrases at that table this weekend, so i think he'll be ready to get it done.

I hope you guys are enjoying this moment of calm the middle of our project. Some of you watching live, live stream might want to take a a smoke break right about here. Um, let's say: go grab a beer, but it's still 11 30.. It is yeah, go grab yourself, coffee, i'd, say for a 2cfm in its application.

It's doing a very good job at this point. We've got a pretty good drop rate yeah. We got a really good drop. All of a sudden, i think we're still flashing off that yeah as soon as we get over the curve of what we're flashing off.

It's going to start coming down pretty quick and that's. Another thing is that, with that happening, you might run into a situation like this, where you have a lot in your system and you need to change your oil halfway through. You never know so you once a lot of times when my vacuum goes down, and i see it start climbing back up again, shut everything off i'll purge with nitrogen change, my oil and start up again and right away. Just boom drops back down in there, especially if you just finished up working on acid systems right thirty yeah, another good lesson: when your system has had moisture or acid in it, you want to replace that accumulator if you can and if not at least dump it.

Oh, it's in second stage now is that what happened that pump tightened up a little bit wow that was cool. It just made a sound change now mind you. How many pumps are that quiet um? None are you sure the pumps are running? That's awesome. We're approaching 2 000.

boom so now we're starting to drop. We flashed off some of that that refrigerant sitting in an accumulator turbulence to the system, and so when you're, adding turbulence to the system and you're kind of breaking up that oil. It's not it's not nearly something. People think that it's somehow the nitrogen is absorbing moisture.

It's that's not what's going on it's that you have refrigerant trained in the oil in the accumulator and the compressor and running some nitrogen through that. Just helps displace it, and it's just experience teaches you that it's not a lot of people are like. Oh well, the pump's not pulling the hoses. It's it's it's refrigerant in the oil.

That's the issue that you're facing, because this is not a wet unit. Of course it is my training unit, so i shouldn't say that yeah, it didn't very well could be a way yeah yeah. It was a good lesson. We went over purging nitrogen if you're running into a situation like this, where you're all sudden your vacuum gets stopped somewhere, yeah um before you pull a vacuum, purge nitrogen through the system flush it out, save yourself a lot of time and we didn't.

Essentially, if we were doing a repair on here, i hope that we pressure tested it yep, yeah yeah. Normally this the pressure test would have automatically been in there. So we're not this right here, it's kind of a worse scenario. You know: maybe your tech got there.

It was empty on gas and he you bear in mind. This is a 2cfm pump, light enough to carry up the side of the building. You don't need your power, you don't need your cheater cord, your widowmaker, nothing like that, so it makes makes it a lot easier on a technician in the field. So we've had a lot more people join live.

So why don't you just tell again why you decided to do this so again, um? What i decided to do is put the equipment to the test in more of a real world application. We've been here for three days and they've been pumping down an equivalent to five ton system, which was a large coil of yoga pipe and on average i mean it was pulling down in a matter of five to six minutes at the most. However, that's a dry system: that's when your guys go install. They do brand new line, set all new equipment.

It's going to be quick, you don't have much in there. This is to kind of represent a system that technician got to maybe change an expansion valve or a compressor, or something like that, and now he's working with potentially fighting against refrigerant in the oils or moisture that's sitting in the oil and then the system hitting an Evaporator coil or wherever, and we're just testing it to see what kind of pull down time it actually has and again this is the two cfm battery powered navic pump. It comes with a 5 amp hour that is capable of up to an hour of run time. Continuous and the 9 amp hour is an upgrade for it and they say you can get upwards to 2 hours out of that battery.

So what did we do wrong in this process? From the start, we did not agitate the oil in the compressor. We did not purge nitrogen through the system, so this was just pulled down recovered. We ended up opening it to the outside air and now we're back. Excuse me now we're evacuating it yeah, so you guys are witnessing us suffer with you live just from the simple step of purging that system with nitrogen, especially when you've opened up to the condenser accumulator.

We went straight from recovery hook, up a vacuum, turn it on nothing, purge and cleaned out and and we hit once we hit 3000 we just boom. We sat there for a long time going up back and forth between 3000 and 4000, as some of the gas still left in the system and the accumulator or the compressor was flashing off and then now we're back down and dropping again. Nitrogen bird surely would have saved us some time classic. Where were all of you? Where were all of you when i needed you, you know i'm.

I got this mic. I can't think about stuff. Where was everybody when it when it came time to be like hey nitrogen purge? Where are my peeps? How much you're charging me per hour it's taking a while anybody around here have something to want to say or add good times. I did hear somebody back there earlier offer up another point for stressing this this test here and i kind of missed it, but they wanted to see this in a little bit different of an application.

Mr steve, can you tap that screen for me perfect see. I wanted to put the four cfm to the test and the navic rep decided: let's go with the two cfm to show you right now. Our restriction to our vacuum time is actually our pump. We have the capacity with our hoses to increase our cfm rate on our pump and we would actually have a little bit faster evacuation time right now.

So jim's prediction was um again. What was his prediction on how low we were going to be able to pull? If moisture has been introduced to this, if moisture has been introduced to the oil of the system many times, he proposes that we'll be most likely sitting around a thousand microns okay. He said it's going to be hard to get under that, because the moisture will bond with the pe oil and the only way to get rid of that is with a fresh filter, dryer good times. It's doing good, though so, probably if i had already had the nitrogen sitting out here - and i was in my work van so we're now under 15, 000 or 1500.

Excuse me under 1500 good. I would have probably by now pulled out my tank flush. It a couple times with purging it with nitrogen yeah and then started it up, because i already know from experience. The dry system is going to take me 5-10 minutes with these hoses.

Regardless of what pump i hook it up to. I like how you, when you see that threshold across all of a sudden, it starts diving again, it hits another either moisture in some another level, refrigerant something sitting in another level. It hits that and it'll dry out it'll stabilize for a little while and then boom. Once it starts dropping once it's cleared that out of your system, that's the awesome thing about having that the app actually connecting to your microphone gauge, you can watch that happen and the wonderful thing about the blue vac app as well.

Is you know it's? It's all recorded all that data can be passed forward and saved to a pdf file. You can even record your your readings while it's happening, i'm looking around who's. Getting paid to stand here must be nice right. All i see is attendee attendee no one's getting paid to stand here.

Wow. This is fantastic. You guys are all a bunch of nerds they're still here right now, hello, youtube. I just wanted you to check a live stream.

Yeah. If you have comments or anything, is there someone who can check on comments? I keep kicking him and, for some reason, he's bothered by this, like you know how many people would pay big money to be kicked by me, 80 people right now, i'm one of them wow, that's cool comments, um! Oh you want me to look yeah any questions. Steve's over here monitoring the comments right now, all right, steve, okay, all right wait! We got some mandu uh 5 30 says call it good charge it beer can cold. Okay, that's not what we're planning on doing, but i get the feeling i said bert should be serving refreshing birds to be serving the refreshments.

Okay, again, not going to happen, yeah any questions not yet well. If you're watching live - and you have a question what's happening. What's going on, why this, why not now's your chance, yeah, we haven't come back up at all good! What's that t-lex says: okay, it's time to bring out the 12 cfm right uh! Also, if you're using this i mean we, we, we have live videos already in the application that you're installing a new system, and you have a clean lines. You've already seen if you watch the other live videos that we've done on this pump.

At this event, you've seen what it can pull down um on a dry system too. So as an installer have something this small, that's capable of pulling your system down a dry system within five minutes. That's pretty pretty hard to beat compared to my times in the field. This is uh still doing pretty good.

All things considered. Can you see that so this is the app we're talking about actually connecting with our bluevac microphone gauge, and you can see the trend. Can i go back yeah and walk through it yeah, i'm just looking at when we actually started dropping once we start stop boiling stuff out of our accumulator yeah. That was a good 21 minutes ago.

Okay, all right right on, we might be walking away from this. Just so, we can take care of some other things of the event, but we're going to leave the the system running we're going to leave the gauge on. We do have a time graph on the app, so it's going to indicate how long it took for us to get to any certain point considering our practices today. This is not going to be the fastest that this can pull down in such an application.

Um we missed the nitrogen purge, but there's an argument against that. Okay, that one right there you're complaining yeah, that's fair! So he said that uh burt was the last one to work on it and that's why it's leaking and has so much moisture contamination and i can attest to that. Personally. That's absolutely true, but again, that's why we wanted this unit because we knew this one had been open so many times and stuff done to it and probably not every time brian's not watching this right is he is he on live he'll, say no, we'll say no, Probably not every time the line dryer was replaced.

Six ten, eight ounces yeah, which is true, which is true yeah. We didn't actually have we isolated all to see if it shoots up like indicating a leak uh. No, we haven't, but we did um. We did hit.

Definitely where the moisture was actually boiling out of the accumulator that we didn't fully finish recovering and the fact that we didn't purge and all of us we do a vacuum, we recover. We do our repair, we have our nitrogen to test the leak, we're already purging. So normal application, we would have done that. Just get my mind in this side, so we kind of scraped this together at the last second, because i was the one that spearheaded this, i wanted to see it on a live piece of equipment.

The the great thing that about this, though, it's a good lesson for somebody who's trying to pull vacuum, how much time you can save yourself actually doing each step in the process right, but another thing um is that you could see immediately once we crossed that threshold Of about 3 000 boom, then it started diving down into a normal backing process, so hey yeah um somebody asks you ever heat, the liquid accumulator or compressor with warm water to help get the refrigerant out of the oil um. No, i haven't done that. That seems like a good idea. Yeah! No! I haven't just torches torches heat gun.

Another question: why doesn't it matter? No matter what pumpkin levels um? The part where i said that is that something i said: it's it's not it's not so much the pump. Okay, you have limiting factors depending on what you're using yeah um. In this case, our limiting factor is the pump simply because we have more capacity available in our hoses right now to use a larger cfm pump and actually have this process moving along, even quicker. However, if you're, using just your typical manifold or hoses that would come on your manifold, you have a major restriction in those hoses that even your 2cfm pump anything over that 2cfm pump you're, not doing anything 2cfm.

At that point, your restriction to speed is going to be your hoses. Another person asking how much that nav pump is talk to your distributor. That might help too. You think you tighten it anymore.

Yeah got another quarter turn out of it. Yeah i got a little more than a quarter. I think it was actually hitting the top of the handle yeah so bert found another limiting factor. We were apparently not completely tight on top of our pump and now we're dropping a little bit faster yeah.

You can see him dancing when i move that that's good. In other news, we've reached a hundred viewers on the live stream. There we go okay. Now we need to just hit one thousand yeah great all right, so, let's, let's hit it from the top again, so anybody that's joining the live stream.

Um go ahead, so we decided i decided to do this. I wanted to put one of the navic pumps to the test on a live system. We've been pulling down what would be equivalent to a five ton. Uh fresh, install new copper, new equipment, gon na be a pretty dry system when you pull it down now.

This two cfm pump that we're actually using right here that you may see in the other videos you'll see how quickly it would pull down your five ton equivalent system and now we're actually working with a system that has some oils some refrigerant in it. We did not do a nitrogen purge on it, so we are missing a portion of the step that would have sped this process up considerably. Yeah yeah. We didn't replace the line dryer, so we went straight from recovery into throwing a vacuum on because you know we're just experimenting we're having fun out here.

This is kind of a worst case scenario for when the pump gets put on a system. How long it's going to take yeah and so there's things like you got a line: dryer that's holding stuff in it. That's had moist been collecting moisture from when it's running and doing its job. That's still sitting in the system accumulator that just had a recovery machine hooked up to it.

No nitrogen perched through and we hooked on, and you could see that you could see the vacuum not be able to pull a certain level for a while, and then it would drop past that and it would stay for a little bit and then pull another layer Out and stay so yeah, so i think we'll hit that 1000 micron by the time we need to step back toward the stage. Okay, yep also helps to have all your connections tight. What's the name of this app, it's a blue vac pro, so yeah blue back pro connects uh with the bluetooth micro engage and then you track keeps track your time and the vacuum rate and it stores it. You can store it permanently in the in your app it'll, actually keep track of the vacuums you've pulled before when you need to pull that out, and it's awesome to see your visual patterns right there and now mind you these uh, these navec battery pumps.

They do have an alert that will alert you when the battery is getting low. It gives you approximately five minutes to go ahead and shut off your pump. There is a valve that will isolate your pump on the side. You can isolate it, go ahead and change your battery turn your pump back on and open your valve back up and continue where you left off yep or your oil.

In this circumstance, so i shut off the um pump to watch the decay test to see what would happen because we never did a leak, leak, detection or anything with this before, and it is popping up pretty fast. So you shut off the pump yeah to the system yeah. So right now we're doing a just a quick decay test um on the system because, like we said we didn't do leak detection, we didn't do pressure tests before to see if the system was actually tight. We are climbing pretty fast.

That is a little concerning, so this poor vacuum's probably been working against at a minimum moisture in our line, dryer moisture and our oil all right open it back up to the vacuum. So we're going to go to go ahead and do is get back to different classes that we have going on in the event leave this on. Let it actually dry this system out fully and we'll come back to it. Anything you want to add before we head out.

Yes, sir thanks for joining us, it's been fun, actually something real life. Actually, thanks everybody for joining in giving advice, we needed it. There you go.
