  Speaker: Welcome to the Refrigeration Mentor Podcast. I'm your host, Trevor Matthews. Super glad that you're here hanging out again. This is so awesome. There's lots been going on at Refrigeration Mentor, continuing to grow the training, helping develop technicians and contractors all over North America, all over the world actually.

  What we're gonna dive into today, tonight, this evening, wherever you're at in the world, whatever time of day or evening it is, we're gonna dive into something that's really close to me. Something I, I talk about mostly in our paid training courses, but. Supermarket, refrigeration installation procedures.

  But inside this package that you would get is that this is the first step for the project manager of the store. So you'd have a project manager that would be working with a foreman. Of that site, looking at all these drawings, getting a game plan before they even get the roof on the building.

  How many fittings do you have? Do you have the installation? Do you have the piping? Do you have the ready rod? Do you have the unistrut? Do you got the hangers? Do you got the, what else? The saddles, all these different parts, and you got glue, you got and then you'll get it in different orders, but you gotta count, I remember counting all those fittings out.
• 0:12
  Then you roll out your pipe and you roll out the pipe and then you put in, you slide in that if it's one in five eight and a five eight line with the insulation on glued really good. You gotta do your best not to rip it. So you put it in there and then you foam the edge so you don't get any air in there.
• 0:15
  All depends, right? So one of the things is when you're starting doing these first starts, there's really nothing there. So you gotta envision where those pipes are gonna go and you're start doing it because before the pipes can even go up, you gotta build those hangers. I, we use three eight ready ride, a lot of that with three eight bolts, nuts and washers.
• 0:18
  So you'll get, depending on how big the job is, how many people you have on there. Us, we usually a lot of like three or four man crews, so we would be like, okay, we're gonna do the 60 foot of produce and we're gonna do, 25 doors tonight or whatever it is, or 50 doors. It all depend on what we needed to get done for that day.
• 0:21
  So what we would do before, we're adding that to another lineup and piping it into like four or five, six other cases, then trying to look for leak. We just look for it right then and there. So if there's no pressure and you get some nitrogen, you get someone to jam it with a bunch of nitrogen, you get two or 300 pounds of nitrogen in that case, and then look for leak, because if there's no nitrogen in it or, and no pressure in it there, it leaked out somehow.
• 0:24
  That just really set me up to really understand the system at whole, because it's a big undertaking to do an install. Like it's a big undertaking. And after you lay out the walk-in box or you lay out the cases, the ne the next step is to, like, for the cases would be to pipe them. And so how are you gonna pipe them?
• 0:27
  Do that behind you, but you get all that in there. There's also the drain that you gotta do. So if you guys are doing the drain, you gotta make sure that you set that up properly. Just remember you gotta have a trap on the cases and then it gotta flow downwards towards the drain. Okay? And so you don't want to double trap anything.
• 0:30
  Well, that's not correct. Actually it should be, if it's three, three and three should actually have it closer to each side. So like, say one and a half and one and a half, and then you have. Four. No, let me do it. That's probably not a good measurement. It's not easier. You'd have two on one side, two on one side, and four in the middle between them, because that's gonna be the way to curve that.
• 0:33
  Cut, troubleshooting times in half, stop guessing. Stop callback, stop stressing and build a team where your best guys aren't carrying the whole load. If you want these results, click the top link in the description, get in contact with my team, and we'll walk you through step by step and how we can get you these results.
• 0:36
  And then after that, if you may not do this is probably, this is an electrician job, but there was lots of times where we're, I'm working with the electricians and we are pulling the wire, all the control wire out to the right places. Some places didn't like that because this is an electrician job, not a refrigeration technician's job.
• 0:39
  What are they going to, where are they daisy chained to? Are they got a star pattern, depending on the manufacturer? But this is so, so important because now, especially with CO2, there's so many case controllers. So we gotta pull wires for the, well, it's usually not so bad if it's RSS 45. So you're pulling two wires or you're pulling mod bust yeah, so usually RSS four, a lot of it Modbus RSS 4 85.
• 0:42
  It all depends on the size of the pipe. The bigger the pipe, the further the hangers can be apart, the thinner the pipe, the closer because they'll just sag. So when you have the. The saddles, you can put the big pipe down and then you can put your liquid line on the top of it, depending on the size of it.
• 0:45
  So if you get non-con condensable in there and then you get a drop right off, like you get when you're coming out, you look what's coming out, it should go down, natural down. And so you look the Hussman manual, the Hill manuals, zero zone manuals, they explain exactly how to do that, how to properly pipe that.
• 0:48
  You get that vapor charge of say, 150 PSIA 10 bar, then a lot of times you're gonna add oil to test the oil system to see how the oil system works to make sure it works, make sure all the component, everything fires properly. So you depressurize the oil reservoir, you fill that up with oil, so it's just say 80% of whatever the charge is supposed to be.
• 0:51
  Wire and issues sometimes. And just programming. And that's why you'll see a lot of manufacturers sending out field startup guys just to help with that, some of that programming. And so af like during this, 'cause this is still kind of part of the install, most of the guys that were doing the pipe work and the case work, they would be moving on to another job.
• 0:54
  Grand opening is this day. We need it open. And there's still, the final commissioning hasn't been done. Like all the safety's checked, the door heaters, the anti switch, making sure the de defrost schedule is firing properly. The light the light settings or the night curtains, making sure the gas cooler logics working. So there's lots of these different things. And then writing all this stuff out, like all the set points that this is before you, you're full of product, right? Grand opening, you're gonna have. It's gonna be full of product, but before that, you're trying to do this with no product in there.
• 0:57
  So important to do this. And there's a lot to it, because it, it comes back to a lot of things in. A job. And really, I'll give you the final note here is the quick synopsis of what we talked about. One of the things is that you need to break it up into different phases, and that's cr probably what it is.

  Well, that means more opportunity for you. For you to learn faster and quicker and fast track your knowledge. It does not take 5, 6, 7 years to become a great refrigeration technician. You can do it in a couple years. You just, all you have to do is put the work in. You just put the work in, put your head down, grind it out.
