All right today we are gon na be prepping an evaporator coil for replacement for a this is a tiny little guy, so we're gon na be putting in a TXV selenide valve. I am taking out the Schrader out of this process, stub right here. So that way, I can relieve the pressure from the coil. My straighter core removal tool won't get in there better option over here, always save these little tools right here that come with your access valves.

There we go. This is that little tool. It comes with a little access fittings that you get. I always save a bunch of them, so we're just gon na relieve the pressure from here up here on the side of this coil is a nozzle.

You got ta make sure you get the right nozzle for the right refrigerant way. The coil feeds promptly. Okay, we'll have to read the instructions on which one to use located inside and panel. So it tells you right here what refrigerant to use for what nozzle.

So we're dealing with our 404 a our unit model is LS o six five, it's a tiny little coil, so in LS o six, five, four, oh four, a it says to use the L three quarter, nozzle. Okay, what we've got to do just pull this stuff out? I'm gon na cut the end off of this. If I can, I'm gon na break this off there, we go to reduce the amount of pressing down in there. I'm gon na go ahead and remove the burrs nozzle pushed in there get your little hanger pushed in there.

This is the tricky part is getting the hanger in. Don't you get that pushed down? You can take whatever you're gon na use, I'm using a drill bit. Sometimes you can use a quarter inch bit and just push it up. Okay, push! Try it up in and I could be able to see inside, but it's pressed all the way down.

So now we can move things around and get this guy put in the position. We want it to be in pull the caps out of the TXV or the TGV, so we're just gon na get it kind of fit up in here where we think it's gon na go about like that and then being very careful not to mess up the External equalizer kind of bend it get it where we want it, something like that and then our liquid line will come straight in me cool. I, like it a lot just kind of mocking things up, get an idea where I want to be: okay, okay and then we'll cut this equalizer lime. Okay, we've got it kind of mocked up about where it's gon na be ready to get some nitrogen hooked up, and we can braise a little Milwaukee m12 fuel driver still doing really good.

I'm really impressed with this little guy kit has a lot of power. Nice clean bit, don't get me wrong, you could do it a lot faster with an 18-volt, but when you don't want to carry an 18 bolt around the Milwaukee 12 volt works. Just fine next thing, we're gon na make sure everything is properly sanded. I like, when you know I don't always use this stuff, but when I can this is the Viper wet rag dig that stuff so we're purging nitrogen through there watch out for your calculator.

I was gon na be careful when you're, braising and there's populated nearby don't want to melt it. Okay, so we've got a key to therm temperature controller with defrost built in and then we're kind of all prepped. We just got to bring power once we get it installed through. One of these knockouts same thing right here will connect the suction line.

Liquid line, pull the sensing bolt through once we're good. So this little guy's prepped, it's just a little guy. I don't like to prep these ahead of time, so I don't have to waste the time on the job all right, so we are piping, the new condensing unit and just like I've done on some other ones. I've made videos about.

I put a bigger receiver on the system, so we're going to repipe. I cut out the old receiver, which is this tiny little thing and making a spot for my liquid dryer to go so we're getting along I'll show you guys so slow progress. We've got the new receiver installed. We've raised the fitting right.

There flared it right here, this receivers, a flare, so we went flare down to the dryer and then we're gon na go flare out of the dryer here's my suction line. I moved it because it wasn't a different spot, so I moved it. It already looked like crap like this, so let me go. It gets my OCD because I like straight line, so I didn't change any of this.

This was already here. I just cut their thing off this valve, which was on the backside over there. So we'll move the valve over here, we'll secure it down. That's 5/8 we'll run the 3/8 and the 5/8 together.

We're not gon na put them on top of the condenser shroud we're gon na go high so that we can take the convinced or out off later on some of these you see like that one I put it on top, but you don't have to take that Shroud off to get this motor out of this shroud, you got to take the whole shroud off. So, that's why we don't want to lay anything on top of that style of shroud, so yeah we're gon na stay high and we're redoing the line set, but because the penetrations in a really crappy spot - and they have this rubber roof. We're not going to put a new penetration, we're going to use the existing like two feet of line set as it goes down and that's it and then we've got all new downstairs and the rest of it up here here. So we're just reusing.

Essentially, one two wells just because I don't want to have to I - was part of them redoing this roof, because I had to come over here and lift up this whole refrigeration rack and that unit right there and this roof is like. I think it's eight inches of insulation. I could say it's: they raised everything really high, so it was but anyways. So I'm rambling at this point so we're getting there.

We just I'll show you guys again I'll show you guys some stuff downstairs in a little while all right, so we pretty much got the condensing unit wrapped up we're gon na you know, zip, tie some lines and clean it up a little bit. That's it. We've got a vacuum down, obviously, but we've just got it all: set up and ready to go. We have a dual pressure control tucked back in this corner over here.

There was no good place to put that. Actually there was no good place to put that. So I put it back there, but I made sure I left a whip on it. So that way, if someone needs to Jack with it, they can lift it out and work on it and then put it back and we tried to secure these to make sure they're not rubbing anywhere and yeah.

That's pretty much it we're all braised in you know, everything's good on the dryer and make sure the sight glass was in an accessible location. That way you can see it we need to. I noticed that this brackets broken right there off to come up with another one of those brackets for that but yeah. That's it nice big receiver, plenty of room in it yeah and that's pretty much it so we're going to go downstairs and work on the bottom section, so we're still working on it.

The new coil is significantly smaller because they had oversized it by a crap-ton plus. This one's more efficient, so I've got it on a vacuum and then we've obviously got to clean up electrical conduits. Do the drain line. You know, put the sets a bowl on so we're getting that p-trap coming through over there.

Nice and good will seal up all the holes and everything so slowly but surely finished with the pressure test. Looking good, so we are vacuuming down right now. What about 500 microns were aiming for about 200 microns, so the refrigeration system, so we're going to try to go 200 and then decay that doesn't go about 500, but everything's gon na get so far using an app beyond hoses a little tight in some places. But they're doing good so far, all right so we're all operating everything's.

Looking good clear-site glass pressures look good boxes at about 42 degrees. It's going to take some time because we had that box up for, like 60 degrees today, yeah everything's, looking good everything support it. Just everything is running just breaking it downtown a little while this little Hardaway we're gon na come back and pull the blue tape off. That's just a little foam back, okay guys, so you guys saw everything that happened inside there.

I broke this up into two videos that way, you know, wouldn't be as long so you guys saw the diagnosis and then you saw the installation. I tried to show you as much as possible, but it's hard when I'm working with all my employees, because I really don't like to show them on camera. So so I showed you guys as much as I could, but everything went good. There was really nothing too difficult, you know.

Whenever possible, I try to feel prep, I mean um, you know prep these before I get out in the field, the coils, it just saves you. You know three hours of two hours, whatever it is of time out in the field everything takes longer when you're out in the field. So if you can do it in an office setting at my shop like I was doing it's so much easier because my bands right there, I could leave the door open. I can come and go from it so anyways.

Just whenever I can. I like to prep them at the shop you know and try to save some time later, the condensing unit, you know nothing special. You know. I told you guys before I really like to use flare dryers up on the roof.

Okay, I'm not a fan of flares in general anywhere besides on the roof, I don't mind them on the roof, but I don't use them down at expansion, valves and evaporator coils because they just tend to leak because of expansion and contraction and in a colder environment. I tend to see more leaks popping up on a flare, so I like to use them up on the liquid line. So that way you know if we ever have to do a repair down in the evaporator. I don't have to take my torches necessarily up on the roof right, because if it's a flare, I could pump the system down.

You know basically change the dryer, tighten it back up and then just take my vacuum pump up and do that so you know that's. That's how I like to roll in those and then I also this one was out in the Palm Springs area. So I went with an oversized receiver to make sure that we had enough room inside there for the hot summer days when the pressure builds up really high. So that way we have plenty of room that is technically an indoor condensing unit.

So that's why we have it. You know mounted outdoors and they put smaller receivers on them because of that, but, okay guys, I really appreciate you guys taking the time to watch these videos leave me some feedback down in the comments. I'd really appreciate it guys. Let me know what you think.

Let me know how you think I could improve all that good stuff. Okay. Until then, I will see you on the next one: okay.
