Hey there, everybody how's everybody doing this evening. Hopefully you guys can all hear me. Okay should be coming through loud and clear. I'd appreciate some of the guys in the chat.

If they could. Let me know if you guys can hear everything. Okay, all right, so this evening we are going to be covering a few things. I kind of wanted to start out by talking about ice machines and then we're gon na kind of go from there and then I'll answer some questions from everybody and see what we can do.

Let me go ahead and clear my screen here, so I'm not staring at myself open up the chat, so I can read that nice and good hello to everybody. That's in the chat, you guys have all said. Hi and I know I haven't responded to everybody. Quite yet, right on cool, I'm glad trying to get past this stuff, I'm getting better and better at this stuff.

One of these days, I'll be ok at it. At this streaming thing, there's a lot of guys that can do it a lot better than I, but I want to clear something up real quick in the chat a few minutes ago. They were talking about air conditioning and refrigeration book. You guys were mentioning the commercial refrigeration for air conditioning technicians - that's this book right here, a very, very good book for those that are just coming in here.

This was just they were talking about this book in the chat. So that's why I'm bringing it up! This is a great book by mr. dick Wars he's a great professor. This is the third edition.

This is the newest one that they have right now they will be coming out with a new one. I've heard he's working on it, but it's gon na be some time before he's finished up. This is a great book for refrigerant to get apologize for that people that want to get into refrigeration it's basically, it doesn't start from scratch. Okay, it kind of covers.

You know it assumes that you already know a little bit about air conditioning and then it just kind of goes into there. It I mean it still does cover some basics, but it's meant to be for air conditioning technicians that want to transition over to refrigeration. So definitely a good read if you guys want to consider that book. I highly recommend it.

That is a great book. So very, very good thing. I know some of you guys they were talking about it too, in the chat are getting ready for a big cold snap coming through, and hopefully you guys do. Okay with that, you know I was joking around in the chat saying that we've got a cold snap.

Coming to and it's gon na get into the 50s, so I was here in California. We don't know what cold is so I wish you guys the best with that one. I know it's gon na be getting cold. Hey there tersh how you doing man yeah.

So I know you guys are gon na have to deal with that so bear with it and hopefully it passes soon and you guys don't freeze to death. So just keep that in mind. You know when you guys have a nice nice mild summer, we're gon na. Be hitting 120 degrees in the summertime here, so you know we're not as bad as Phoenix out in SoCal, but we're gon na be getting some hot summers that a lot of the Midwest and back east doesn't get so we'll get ours come summertime.
So so what I kind of wanted to start out talking about was uh ice machines. I'm gon na specifically talk about Hoshizaki ice machines because you know I, the video that I released this morning was on a hoshizaki ice machine and it was just kind of it. Wasn't like a real, full, in-depth video, it's just kind of a quick tip, one of the most common problems that I get on a HOSA sake. Ice machine is thin ice cubes and it's very common when you have a dirty ice machine.

Okay, and if you guys haven't watched my video already that I uploaded this morning, you know it. Basically, I had sediment stuck in the pump out Springs check valve and it was allowing the water from the water pump to bypass. So I'm not gon na break them down like crazy and depth, but I'm gon na give you guys just kind of a basic understanding of how the Hoshizaki ice machines work. Okay, so first off a hoshizaki ice machine.

When you turn the machine on, it is gon na start in a harvest. Okay, I'm not gon na go through every single thing, step-by-step. What I would HIGHLY highly do or suggest you guys do - is get a hold of your Hoshizaki distributor. Get you one of these tech specs book? Okay.

I know a lot of people keep asking me how they can get them. What you need to do is you need to call Hoshizaki PartsDirect. Okay. Now I'm sure you can call your supply houses too, but hoshizaki has their own parts, distribution, supply houses and you guys can order.

Then, okay out here on the west coast, they call it Hoshizaki, Western, okay and there's about five supply houses, one or two in California. There's one in Vegas there's a couple of them: okay. So when I order my Hoshizaki Parts, I don't order them from United refrigeration or RSD or allied or whatever John Stone. Okay, I go directly to Hoshizaki alright, so I know a lot of people have said they were having a hard time getting that book.

I would highly suggest you guys get a hold of the Hoshizaki parts distribution warehouse and they will be able to sell you that book, okay or they will at least be able to give you the part number. So then you can go back to United refrigeration or John Stone or whoever you guys get your Hoshizaki parts from. I know a lot of people have been saying: they've been having a hard time getting those now. You know a lot of the manufacturers of refrigerators and ice machines are trying to get away from the the printed books because they they're trying to save money and whatnot okay.

But you know the way that I go to them. Is I don't ask for a free book? I ask them hey. I want to buy three of those books. Can you give them to me, you know, and then I buy a couple at a time that way I have them.
Okay, so I highly suggest you guys get that book if you're gon na be working on Hoshizaki ice machines - okay, so I'm gon na break their machines down just kind of a quick overview. Okay, so the ice machines gon na start in a harvest cycle when it starts into a harvest cycle. What's gon na happen is some hot gas valves are gon na open up, depending on how big your machine is, once the hot gas valves open up, it's gon na warm up the evaporator okay, when the refrigerant coming out of the evaporator makes its way to a Thermistor, that's mounted on the outlet of the or mounted on the surface of one of the lines coming out of the evaporator. When that thermistor gets to a certain temperature, it's gon na initiate a sequence.

It's gon na stop the harvest. Then it's gon na put the machine into a freeze mode. Okay, now one of the and again I know there's more to it guys, but I'm just kind of giving you guys the little quick in a nutshell - breakdown. Okay, so I'm just gon na kind of go back and forth on different things on this, so it's very important to understand that when we are coming out of a harvest that that thermistor has to reach that certain temperature.

Okay, if I was more prepared I'd tell you the exact temperature. I think it's like 48 degrees or something like that, but it has to reach that exact temperature. Then it starts a timer sequence. Then it basically ends the harvest.

Okay, another really important thing when it comes to the harvest - and this is my is or - and I've had videos on this before - is that we have to have the right amount of water coming into the machine. Okay, when we harvest a hoshizaki ice machine, that's when we defrost the ice off of the evaporators. Okay, two things happen: number one: we've got hot gas flowing through the refrigeration lines, okay, but the other thing that's happening is we're bringing fresh water into the machine that fresh water has to come in at a certain rate, a flow rate, and if that fresh water Is not coming in at the correct flow rate, then what you can have is consistent. Freeze, ups, okay, those freeze ups are what damaged the Hoshizaki evaporators.

I would say I bet you a large percentage of the machines out. There do not have the right flow rate coming into the machines in the Hoshizaki Tech Specs book, okay, for the new guys that are coming in I'll. Tell you right now this guy right here in the tech spec book it is gon na. Tell you what size lines you have to have now: it's not just the line size that matters.

Okay, it's still the flow rate of water, the gallons per minute at which that machine can fill. There's a really quick, really easy test. If you're, looking in that tech specs book, it's gon na tell you how many gallons per minute that particular machine via your model number requires. Most of the machines that I work on are the bigger machines.
So they have a 5 gallon sump okay. But if you look in the book, it's gon na tell you how many gallons of water, the water, something that machine holds so the quickest way to test the flow rate of the water coming into the machine is to turn the Machine off. Then turn it back into a freeze cycle. Okay, the first thing it's gon na do is it's gon na start filling up with water? What you want to do is make sure your your water sump is completely dry and out of water.

Okay, then, what you're gon na do is you're gon na tight, you're gon na start a stopwatch when you turn the ice switch to on right when the water starts to flow and when the water comes out of the overflow, which would be down the bottom of The ice machine drain once it starts coming out of the drain. You know you have filled that sump on my particular case, we're talking about a five gallon sump. So if you have a stopwatch going and then the moment that you see water coming out of the drain, you know that you filled that sump up. You can stop your stopwatch and then you can do the math to figure out the gallons per minute at which that machine is filling.

That's one of the easiest ways. One of the first things I do after a afrezza on a hoshizaki is, will test the bin thermostat and then we'll test the flow rate of the water inlet. Okay, now things that can affect your water inlet is just plain and simple: low, building water pressure; okay, but dirty filters or improperly sized water lines or in the instance of a hoshizaki video I did about two months ago. Someone installed the wrong water inlet valve on the machine.

Okay, you don't use the same water inlet valve for every single Hoshizaki machine, again open up that tech specs book, and it tells you, via the part numbers on there. What water valves to to put in the machine? Okay and - and it tells you the flow rate of each particular water valve Hoshizaki - makes like five or six different water valves. Okay. So, a couple months ago I made a video where I found that someone had a water valve for like a 400-pound machine in a 1600 pound machine and it wasn't getting the right flow rate and they had damaged evaporators and all kinds of stuff.

Okay, so really really important, when you're working on a hoshizaki machine to make sure that you have the proper water flow coming into the machine. Okay and then you also follow the water line sizes that they recommend and remember that, just because you go to the hardware store or Home Depot or whatever, and you pick up one of those braided water hoses, that's 3/8 connections. It doesn't mean that the the inlet of that hose is 3/8 in diameter. Okay Hoshizaki tells you that, on you know whatever particular machine, they want a 3/8 ID water line coming into that machine.

Ok. 3/8 ID. So you got to keep that in mind whatever and it changes per machine. So it's not always 3/8.
Sometimes it's half-inch. Sometimes it's less okay. Now the reason why Hoshizaki is so critical on the water inlet most all the other manufacturers, it's not as critical on the water, inlet pressure or water inlet flow, okay, but Hoshizaki uses that water to harvest the ice. So remember two things like I said: the hot gas from the the hot gas valves starts to warm the evaporators, but then they have to have that water flowing over okay, the water does two things mainly: it breaks the the seal or the vacuum that the ice Has created on the evaporators okay now on some of the newer Hoshizaki machines, there's not a lot out in production yet, but on some of the newer ones.

They also have a positive harvest feature where it'll actually turn on the water pump for a certain amount of time to help, and that is a big thing that they've been working on to try to make that work better. Okay, so basically, you may see some different things so you'll see water coming into the Machine. Fresh water you'll see hot gas go into the evaporator and then every once in a while you'll see the water pump turn on and circulate water over to okay hoshizaki'he's been doing a bunch of things to try to help some of the freeze ups because they've been Having a lot of freeze up problems and they've been having a lot of bad evaporators where evaporators starting to separate, they had a huge run of that over the like the last two years, where they've, maybe three years, where they've had a lot of bad evaporators. Okay, I I'm sure there's something going on at hoses Aki side, but I really really think that the biggest thing is that people aren't realizing how important it is on a hoshizaki ice machine to have the proper water flow coming into that machine.

Okay - and let me clarify again just to reiterate we're not talking about water pressure per se, we're talking about water flow, because you can have sixty pounds of pressure go into that ice machine and it still might not have the right flow okay, so you got ta, Make sure that you have the right water flow going into it? Okay, so, okay, so really really important on that. The next thing on a hoshizaki ice machine - that's going to happen, is or that I want to kind of point out - is that Hoshizaki ice machines rely on the water flow to tell the machine when it's full of ice or to tell itself when it's time to Get rid of the ice off the evaporator okay, so basically, as the water pump starts to flow, okay and the evaporator starts to get cold. When we go into the freeze cycle slowly, the water is gon na get lower and lower inside that sump. Okay, because the odd the waters starting to freeze into ice cubes, okay, so as the water gets lower and lower and lower the water float, picks up on that and then once the water flow picks up on that there's some timers involved in that it knows that It's time to harvest the ice okay.

So it's really important to understand that now you know a lot of people like to blame. A water float for a freeze up. Okay, I don't really buy that. Okay, I freeze ups, in my opinion, usually aren't caused by a water flow.
Okay, freeze ups, in my opinion, are usually caused by bad water flow coming into the machine, bad bin, thermostats or it could be some kind of other mechanical problem. Hot gas valves not working or something like that. Okay, but freeze ups in my opinion, usually are not caused by a water float. So if you're chasing a water float down the you know, you know be very, very cautious about just changing a water float.

Okay, it's very rare that water floats go bad. Hoshizaki has actually redesigned their water flow and made it really less susceptible to calcium, buildup. Their water floats used to be square and have sharp edges, and now they have like a rounded dome and they really really calcium doesn't affect them as much as it used to a long time ago. Okay, so just keep that in mind.

So, as far as a bin thermostat test - okay, that's one of the other things that can cause a freeze up on a hoshizaki. So you again open up the tech specs book. Okay, everything I'm telling you guys is just stuff that I've read out of their book. Okay, you just got to open it up and read it so in the book it's gon na tell you, you take a scoop of ice and you submerse the bin thermostat.

Now the newer machines have like a paddle switch okay, but the older ones have a bin thermostat, so you submerse the bin thermostat in ice and basically you count how many seconds it takes for the machine to turn off and for the machine to turn on now. If I can give you guys a tip if you're working on an older machine that has a bin thermostat, take the machine out of freeze mode turn, the water pump on put it into a wash cycle and test the bin thermostat, the water pump, will turn on And off, even in the wash cycle with the ice touching the bend thermostat. So that's a really quick way of not having to wait for a compressor to turn on and then have to turn a compressor on and off, or listen for the circuit board. To turn on and off just turn, the water pump on put your hand on the water pump.

Take that ice scoop and you know, put it on the bend thermostat. Now the newer machines they've got that little paddle switch it's a little bit different. Okay, again just follow the the book. The paddle switches, in my opinion, don't go bad as much, but the paddle switches are a little bit more susceptible.

In my opinion to calcium buildup, calcium can get back behind the paddle switch, especially because people don't realize they have to clean those paddle switches and they come apart. But you have to be very, very careful because you can damage them and break the little ears off of the paddle when you try to pull them apart, so you can pull that paddle apart, you can take it. You could submerse it in ice machine cleaner and then you know go about that. But again you guys need to read the Hoshizaki book.
It's really really gon na help you guys with that stuff. Okay, let's see so we covered the fries up. So I'm not gon na go through everything on the hosh ease. Let's see, obviously I would highly suggest if you guys are replacing any parts on a hoshizaki ice machine.

You always use the OEM parts, don't try to get, and this is just personal preference. I'm not chastising anybody because they choose to buy aftermarket parts. Okay, I prefer to use OEM parts on a hose on any ice machine. Okay, because they're designed specifically for that machine, condenser fan motors, aren't typically just a fan motor.

You pull out of your truck. You know same thing with the water pumps and different stuff like that. Just just try to stay with the OEM stuff you'll. Your life will be a lot better when you stay with the OEM stuff, okay, personal preference of mine, so yeah, obviously just keeping the machines clean.

Okay, Hoshizaki machines can last a lot longer without cleanings, but still I highly recommend at a minimum. A hoshizaki ice machine has cleaned every three months, at least just like a fast cleaning and then like a thorough cleaning every 6 months. If you can get it, if you can get your customers to clean them more often, then it's it's much better. That way.

Okay, in all reality, most customers only clean their machines two times, maybe one once a year just depends if I could get them back to you know at least a minimum of quarterly cleaning. I find that the service calls go down quite a bit and the machines last a lot longer so, okay, before I forget, I'm gon na kind of probably stop talking about the Hoshizaki ice machines. Actually I'll go up and check to see. If there's any questions on him, okay, but I wanted to say just make a public announcement that I had mentioned - we had a RSES conference this past weekend, we had mr.

eugene silverstein, he's the author of a lot of different books. He works with the ESCO company. He came out and talked about air balance and psychometrics. I just want to say thanks a lot to Eugene for coming out.

That was really cool of him. You guys I've had a lot of people. Ask me about our SES. Our SES is a regional organization.

They're nationwide they're, even in Canada, they they do training for air conditioning and refrigeration. If you can find a local chapter, that's active I'd, highly recommend you guys look into our SES. It's a great resource and my chapters very active we're the arrowhead chapter here in San Bernardino, California, and we do a meeting the second Tuesday of every month and then once a year. We do a big seminar, which is what we just did with mr.

eugene silverstein. This past weekend, so but thanks again to him so before I forget, I just wanted to mention that. So, let's see I'm I'm assuming Carlos you're asking me Carlos Cervantes, you said: how can you apply with me? Anybody that's interested in sending me a resume or anything just email. My my email HVAC our videos at gmail.com, one of these days I'll give the nightbot that email address that way it can kind of post it throughout the stream.
Here, I'm just gon na go ahead and type it in here. You guys can email me any questions. You guys have anything that I don't get to in this chat. You guys you know, go ahead.

Send me those questions and stuff. Okay, okay, so I'm gon na go in here, real, quick and just see if I missed anything in the chat before I go too much further and see if there's anything going on okay. So let me go down in here: okay, cool um, seeing what I'm missing here yeah. I definitely suggest you guys get the Hoshizaki book um.

You can download them too just go to Hoshizaki americas website and you can download all the manuals and books and different things. But i just prefer to have a paper book in my hand: it's a great great resource, so hello to everybody, that's saying, hi! Sorry! I didn't get to you guys yet so, okay, so DJ sub err. You said where, where am i ad, I'm assuming you're asking where I'm out I'm in Riverside California, so okay gon na keep going down here? Yeah there you go Sackman. Do you said in the Ohio area? It's Hoshizaki north central.

So you know just just look for the Hoshizaki parts houses, because you'll you'll have much better resources there. Now I will say the interesting thing is: is that the Hoshizaki parts houses really aren't that much cheaper in my area, you can that what they started doing was they started stocking a lot of their parts out like united refrigeration and RSD and allied refrigeration out here, Which is a good resource, you can get the factory parts from those guys too so, and the prices aren't too too much cheaper, so are more expensive, so, okay, Brian Milburn, you said anyway, let's take the family out to eat and randomly check your ice cubes to See what kind of ice machine they use? Yes, I do and it's funny you bring that up. You know I posted some videos about dirty-dirty Manitowoc ice machines. Okay, we've all seen dirty ice machines.

They all exist. I'm gon na tell you guys that I still eat ice. You guys that that stuff doesn't freak me out as long as I don't see things crawling in the ice machines. You know.

If I know I have a restaurant that doesn't service their stuff and it's one of my restaurants yeah, I might not eat there, but I'm gon na be honest with you so long as I'm not going to the the famous sandwich shop that everybody knows where you Can get five-dollar footlongs? I get ice pretty much everywhere else. Okay, you know, ignorance is bliss. If it's not one of my customers, I just kind of you know move on as long as I don't see something nasty in my machines, I just I'll get it and I'll drink it. You know doesn't freak me out too much so alright, I'd love to talk about other ice machines too, but I'm not gon na fill this one up.
Maybe next time we'll talk about Manitowoc ice machines, so, okay, cbcb yeah, let's see that's it man. I there's some places. I mean if it's a place that I really really know is gon na be disgusting. I won't go there in general.

If they can't keep up their ice machines, they can't keep up their other equipment, but I still go to fast food and get a soda or water ice tea or whatever, and you know I don't really stress too much so I'm gon na keep going down here. Seeing what I'm missing yeah, I hope that solves your problem, Greg Greg Burnett said he picked up his water valve. You were the one Greg talking to me about uh. I was communicating with you about a freeze up right.

I believe that was you so hopefully that fixture fixes your problem. Jeff, you said so just run copper. Let's see the smaller machine, they come half-inch thread connection. I use half inch CPVC yeah, I don't know.

If I'm missing something there Jeff hoshizaki, I mean you can use I've used pecks lines before to pecs. Actually I'll be honest with you pecks lines, if you get the the food-safe ones, they actually, in my opinion, have better flow than then using some of these braided fittings and whatnot. So the only problem with the pecks lines is: is they they? Don't? You know you can't make them look as pretty you can't. You know I mean I know you can put 90s everywhere, but you know that that's defeating the whole purpose of using pecs.

So it's hard to keep them. Looking really really pretty, I've done a few of them in packs, and I mean it turned out. Okay, they were easier. It's just a little bit difficult case Services LLC, you ask when is it and when is my next giveaway? You know, I don't know.

Let's, let me lean on Milwaukee tools and see if they want to send me something for a giveaway, we'll see I'll see. If I can't get something going on, I'm trying not to to kill you guys with with tool, reviews and whatnot. So you know, but I'll see if I can't dig up some stuff to give away, let me reach out to a couple manufacturers and see what we can do. I'd really, you know it'd be really cool, but I don't think they're interested in it is.

If Hoshizaki could say me a bunch of those Tech, Specs books, maybe I'll, send him an email, I know they subscribed to my channel. I could ask him if they could send me a bunch of Tech, Specs books, and I can give those away too, because I know people who dig those so ok kind of going down here see if I'm missing anything keep on going. Bear with me here. Hoshizaki flaker x', it's been a while, since I've worked on a hoshizaki flaker, but those things are pretty darn easy just got to keep them clean when you start hearing a hoshizaki, flake or screaming at you as the gear motors.
Turning and you hear, though, sounds like coming out of the gear motor sorry, I know that probably sounded crazy, but that's usually what they sound, like. That's usually an indication of a dirty evaporator barrel on the Hoshizaki machines and they're, just trying to scrape the stuff off the side so yeah that Hoshizaki flaker is there they're, not too bad. I used to work on him a lot. You know biggest thing on a hoshizaki flaker is the gear motors.

They would fail because people weren't cleaning them properly. You need to do your bearing checks on the gear motors, if you guys open up again tech specs book right here. If you open up to the back, it used to be that they had a separate book for the flaker'he's right, there's a little piano wire, that's a bearing gauge for the flaker ice machines. So you take that out, got to read the book and it explains how to do it, but you put it you basically don't want that to be inserted into a certain part of the bearing and that's how you test to see if the bearings starting to have We're on a flake or ice machine, so it used to be that Hoshizaki had two different books.

They had one for the flaker and one for the cubers, but now they basically have the flake errs on the backside, cuber stuff and it's all in one book. So those same books, you can get from every ice machine app manufacturer out there. So okay kenny brown. You asked if i do any hot side repairs in my restaurants.

No, i don't. I don't do any hot side work at all. I just do refrigeration and air conditioning, so just HVAC are so yeah. Damien Damien says knowledge.

Is the giveaway I'm running out of knowledge, guys now, but any recommendations for refrigeration, specific books, Julius? I don't know if you saw the beginning part of the stream. If you want refrigeration books, commercial refrigeration, for air-conditioning technicians by dick Wars is one of the best refrigeration books out there other than that, you can lean on individual manufacturers for, for you, know, product specific information, and you know they can they can get you that information? Okay, so, but I highly suggest the commercial refrigeration for air-conditioning technicians, so, okay going to keep going down here, yeah exactly Rad's yok. You said just Google Hoshizaki Tech, Specs PDF available for download. That's right! You can download it yourself onto your phone also on the newer Hoshizaki ice machines.

They have a QR code on them. You just scan the QR code with your phone and then it'll automatically open up the it'll. Take you to their web page where the book is at so it's really easy. Steve Javie uh see you said: can I do an in-depth cleaning of an ice machine? Well, I can - and I can't okay so and I'm gon na go ahead and address this right.

Now I have had a lot of people asking me to make my videos longer to show more details to show me doing the actual work. I don't want to disappoint you guys, but that is what my channel. That is not what my channel is about. I will never ever be a do-it-yourself YouTube channel.
Okay, I refuse to be a DIY YouTube channel, so strategically. When I make a video, I usually show you the problem. I usually show you some interesting things while I'm repairing it, and then I show you the end result now I don't mind showing a little bit of cleaning or a little bit of this, but I do not want my videos to ever be a resource for a Non HVAC service technician to come in and try to do the work without having to call a properly trained service technician. Okay, so for those of you that are worried about it, I will never be that channel and for those of you that are asking me, I'm sorry, I'm not gon na be a do-it-yourself Channel.

Now I do have some videos where I I kind of talk about the cleaning process very thoroughly. I have a Hoshizaki ice machine service, video, where I talk about how I clean a machine and the interesting steps that I do. I'm kind of looking for a video right now and I'll share it with you guys, and I have no problem telling you guys about that stuff. Oh, I never show you every single step of my cleaning processes.

Okay, number one, because that hurts my youtube channel. Not so much that I'm concerned about my YouTube channel but YouTube if I make a 30 minute video and only 2 % of you watch that full YouTube doesn't like that, and they they D rank my channel essentially or whatever is you want to call it? But I mean that's not the main reason why I do it it's mainly just because I do not want to be a DIY channel ever okay. So let me find this video right now and I'll share a link to it and you guys can and if you guys noticed too on my channel, I have playlists. So all my videos are categorized in playlists.

So if you go to my channel and you look up the ice machine, playlist you'll find all my ice machine videos if you go to the refrigeration, playlist you'll, find refrigeration and the air conditioning and so forth, exhaust fans and all that okay. So I try to organize it in playlists. I wish that YouTube had a better setup as far as their organization goes so, but they don't so yeah and Hoshizaki does have a youtube channel. Almost everybody has a YouTube channel.

So let me see I'm looking for this. Okay, here it is right here, so let me pull this up and make sure it doesn't start, because I think it's going to try to start the video nope. Okay. So that's perfect! Let me click Share and ctrl C, and let me go ahead and share this on the chat, control V.

Whoops! That's not that there we go just one sec if you guys want to copy and paste this link, that's a good way to hey Mike how you doing you finally made it cuz. I started late today, huh so Mike Harrison he's been asking me to start my my streams a little bit later and I was running late today, so he was able to make it so yeah. So I just shared a link to the Hoshizaki video where I made. Okay, Ryan B, you asked me: what do I work on that gives me the greatest satisfaction, but the favorite my favorite thing to do is when I do get to do like refrigeration installations and retrofits, because I don't do new construction, but I do retrofit work.
My favorite thing is working with the tubing benders being able to go into a job, and you know, especially with like 3/8 and 1/2 inch, and make a really good clean job bending everything minimal, braze joints, nice clean bends. I love doing installation love working with my benders love doing that kind of stuff. I like to be able to finish installation job and step back and look at it and say man. You know the next guy that works on.

This is going to be happy because everything is serviceable. I really like doing that and, of course I love troubleshooting too. So, okay, so hang on. Let's see gee Martinez, you say you're feeling extra trollish did I say something you did.

That was troll a bull. Oh, I gotcha gotcha HVAC school shirt. Okay, god she got. You oh come on man.

I got to support HVAC school, even if everybody doesn't like HVAC school. I just I have a shirt. I put it on so all right. I see what you're saying there, but all right.

Okay, I'm gon na go back up here and see what I missed. What's on the CD in the words book, I believe it's questions. I believe it's like chapter review, questions Jai Juarez. I believe that's what it is.

So, okay, so um yeah, that's kind of what I go with Jay bug, oh six, beginning middle and I usually don't show the whole thing. So. Okay, I'm gon na keep going down in here, seeing what I miss him in the chat guys so yeah. Seeing here.

What's the worst AC, I had to fix Jay bug. Oh six, you asked, I found some interesting ones so last summer I haven't even fixed this one. Yet but last summer I posted a video of a five-ton split system in a restaurant that had basically enough duct work for a two-ton system. I believe it had one fourteen inch supply coming off of the plenum, and that was it and then that 14 inch supply ran full 60 feet and then split off to three different registers.

The restaurant finally just approved that repair. I have the equipment sitting in my shop, so we're gon na be doing that one here soon. That was a really interesting one. So you know someone else had installed a split system and yeah it had.

One 14 inch run coming off of it. It was a five ton split system, it had a leak in the evaporator coil, so I condemned the whole thing and just it's a fan, coil unit, so there's no heat at all. So I just got a whole new fan, coil and hopefully gon na - be doing that in the next month or so so that was all the way from last year. That was the interesting one.
Okay gon na keep going down here. Okay, interesting Chris Ian, let me see if I can find another one here: huh should work. It pulled right up on my phone, my computer. Let me try it again here: copy control C: let's try this again.

Krissi control V see if this works waiting for it to post here, just a sec. There we go. I don't know if this is the same link or not. Try that one okay.

So what determines how you position? The bin switch on an ice machine Mike Harrison. So on a hoshizaki ice machine, they basically make it plain and simple for you, the older machines have a thermostatic bin switch okay. So basically it's a temperature controller. Okay and it already has a bracket.

That's that's set up. It is important that you, you pay attention because the bracket, depending on what machine you are there is an extension you have to add to that bracket depending on the band too, but it's pretty much all set up on a hoshizaki and on the newer machines. They have like a paddle switch and the same thing like you. Don't move the bin switch at all.

It comes factory installed and you just leave it where it is unless it needs to be extended down, of which the factory has an extension kit for it. So usually it's nothing that you're gon na change in the field. You just keep it where it's supposed to be. Unless the machine is like completely butchered, you know, if someone's trying to make an on dispenser machine trying to work on a dispenser, then you'd have to do some interesting to make it work.

But okay, what is the most facepalm w2f call you had where it was something so simple like the client just had something unplugged or didn't turn on the system? Well, exactly it. I've had multiple calls where you go out there and the client just has something unplugged. I'm trying to think about that one for a minute. Let me think if I have a really funny one I mean I had you know, there's there's so many of them where the clients have called me and I try to well.

I try to walk my clients through things on the phone and say: hey, I'm sorry, Chris II I'll have to share that later or something I don't know why the links aren't working in here. That's strange! Okay, so it works for you HVAC our trucker. That's weird! Okay, so you said the second link does work. Okay, I'm sorry! I read that the wrong way yeah.

I don't know why I didn't work the first time, but as far as weirdest calls off to think about that. Maybe I'll talk about that on the next stream. Cuz I come across some weird, weird stuff. Someone had asked a little while ago.

If I work for myself. Yes, I have my own refrigeration and air conditioning company. I work with my dad. I was trained by my dad many many years ago and we work together.

Now we own the company together and run it together. So, yes, I've never worked for anybody else, but the company I work for now. So all right, how do you, okay, cool, Robby, G, interesting? You asked this question. He says: how do you unroll soft copper and keep it straight? You can never get it to look good, so you prefer running rigid.
Okay. If you're gon na do a piping job, then yes, you do need to run rigid because you're never gon na keep it straight, but there's some tricks you can do so if you're on the roof. What I would suggest you do - and I just had a technician where I one of my guys - we were just talking about this about a week ago and we were doing an ice machine installation is find the roof. The roof lines from like the tar paper.

That's on the roof, usually you can see lines or you can find straight lines from the PTO roof or something like that and use those straight lines as a guide for you. What you do is you place the copper on the ground and I could probably try to make like an Instagram video or something like that, but you place the copper on the ground. You very carefully make sure you get the outside of the role you don't want to unroll from the inside of the role. You start it with your hand, just roll it flat, then carefully put your foot on it and keep stepping on the copper carefully, not to smash it and roll it out as you're stepping on it.

That's a really easy way. If you're working down in the restaurant use the grout lines on the tile and the grout lines are usually pretty straight too, so that's the best way that you can get soft copper to be straight. Basically, okay, but if you're gon na be running a long long line set and it's gon na be visible and you're worried about the looks, then I'd highly suggest you go with rigid, because Ridge is the only way it's gon na look really pretty okay, so Jack Derp, if you said, can you have some free consulting uh-huh? I don't know what you mean by that. If you want to email me something Jack, I can talk to you in an email.

If you got questions, I don't know if you're a business owner or a restaurant owner or something I have no problem. If you want to email me - and I can talk to you over email or something like that sure, so how often do ice machines get cleaned? Well, Jo, its Jo 65. Basically, you know you need to clean them at a minimum. I would say every three months: it all depends on the water quality that you have in that situation.

Where your ice machines located. Is it? Do you have a lot of bake? You know like a lot of yeast in the air from like you know: sandwich shops and whatnot they'll get a lot of slime buildup in their machines because they have that yeast in there and it just gets into the ice, and it just makes it nasty okay. So it just depends on your situation and what you have in your restaurant that would warrant more cleanings or less cleanings. If you have like a Manitowoc ice machine, they require a lot more cleaning.
I would say a Manitowoc definitely needs to be cleaned every three months, but I one could argue. We used to joke that the Hoshizaki machines you could weld them shut and not touch them for a year. They'll be nasty inside but for the most part, they'll keep making ice. Okay, but a Manitowoc ice machine.

They those things, need to be cleaned. I mean yeah, they won't last six months without being cleaned, they'll, just they'll start breaking down because of all the water, sensors and stuff. At this moment in time, Hoshizaki isn't using sensors inside the water area. You know, for the most part they're just using a mr.

on the the refrigeration line outside of the water area, so they've done really good at keeping making their machines last a lot longer and not have to be cleaned as much but they'll still be nasty inside. You know, but they'll still just keep making ice. So, okay keep going down in here, oh yeah, I'm sure gee Martinez, I'm sure I got a bunch of stuff that can that you control me on so keep going down in here see what else I'm missing here see what'd, I say on ice machines. I get this question a lot.

How come I don't use PVC drain lines. I always use copper when I'm piping an ice machine, whether it be a hoshizaki or Amana talk. The reason why I do so most of the time it's very difficult when you run a drain line to replace it so on the newer Follet machines a lot of times. They have a smart gate system where the Machine sits up 3 feet, and then they have a cart that goes underneath them.

Those ones are a lot easier to get to ice machines pushed back into a tight space and what I find is is cleaning crews come through and they try to clean underneath the ice machine and they usually grab a squeegee and then they'll yank on things, and They get it stuck on the drain lines and they bust the PVC drain lines and then it's a mess to try to repair. That is my worst. I hate fixing PVC drain lines on ice machines, so personal preference. That's why I always use copper drain lines on ice machines.

That's just my the way that I do it and the cool thing about copper drain lines. I got a bunch of people being pissed off about my comments, but what I usually do is I braised or I solder the copper lines together, so it out of spot where you know once I've soldered all the lines and they're good I'll, usually take the ice Drain and that you know if I've got two ice machines sitting on there and the two machine drains and then in a very convenient spot, I'll, just very carefully heat them up and lay a bead of solder on there, and that usually adds all the support. You need, for the most part, sometimes you'll have to put like one more support, but I find that it makes it very easy by soldering the lines together. I just prefer copper.

So just a personal preference, okay keep going down here, Joel maneger! You said most of the time coming without the extension connection yeah. That is one thing that Hoshizaki does do. I don't know why they don't necessarily always send the long extension with their machines. So a lot of times if you're selling a new machine or you come up on a machine that has had a lot of freeze ups.
If you look at it, it needs that extension bracket. That video that I posted a link to. I talked about the extension bracket because that's something that I added to that machine to help reduce the freeze ups on there. So, okay, so I'm an you said you were an electrician for three months.

You loved the work but absolutely hated the tradesman. You have an interview first year, HVAC apprenticeship be humble and just learn as much as you can man. You know. Hvac is a great great career and the fact that you came from an electrical apprenticeship or you were an electrician.

You know that maybe you've got some. Some electrical skills, I'm gon na, say that HVAC is gon na mash, plumbing electrical and just basic common sense. You've got to have them all to be an HVAC technician. We really do do a lot when it comes to HVAC and refrigeration.

We are constantly working, doing electrical work, doing plumbing work, solving electrical problems and plumbing problems. You know we're doing it all, so we'll definitely help you guys. Oh yeah, that was an interesting one, DJ sub air. He reminded me that I had a service call.

I had to drive. That was a very good point. There DJ said her, so I had to drive about two hours away from our shop because of ice machine that wasn't work. You know the complaint was water was going everywhere.

I think I can't remember what the complaint was, but anyways I had to drive out there and people cleaning with the squeegee pushed on the ice machine drain. I don't even know how they did it and they shoved it onto the tile completely. Oh, that's right. Okay, so this it's coming back to me now, so the service call was on the ice bin was leaking, there was water leaking all over the ice and out of the ice bends.

So what was happening was the ice bin drain had got pushed up out of the floor, sink onto the tile and completely sealed off 100 %, so no water from the ice bin could drain out there. So as the ice melted in the ice bin, the water just built up inside of there, so I literally had to go out there and grab the drain line, and I made a video on it and just yank on the drain line and pulled it down into The drain, what I did was, I actually cut it shorter. So that way it could never happen again, but that was a silly call. I had to drive two hours out there billed for two hours.

You know and then drove two hours back to the shop and didn't get paid for those two. Our wallet company didn't get paid for those two hours and yeah that was kind of a silly one. That was a silly call for sure. So, okay, orlansky ellis, you asked constantly adjust the Hoshizaki bend thermostat.
Can it fill okay? I highly suggest you never ever adjusted in thermostat the only the only in my opinion, personal preference. The only reason why I would ever adjust a bin thermostat is, if I was in a really high elevation: okay, Colorado, you know or something like that - really really high elevations. I imagine you would need to just the bin thermostat, but most other times if the bin thermostat comes factory set, and I never adjust them if the if the bin thermostat is not, you know, working correctly, you change it adjusting it. You know it might get you by, but there's there's no reason to so III.

Personally, don't ever adjust Ben thermostats and, like I said you know, going into high elevations I've. Never even you know, adjusted one for high elevations, but I would imagine that you know someone working up in Colorado or Denver or something like that would have to maybe adjust them on startup, but then, after that you should never have to adjust, have been thermostat again. I know there's a screw slot on there, but really you shouldn't, I just don't even touch him. So okay keep going down and what's the worst HVAC our pump down gone wrong story.

You have heard or if you have dealt with personally, I'm assuming okay. So I don't know what you mean by HVAC are pumped down okay, so you know I mean I pump systems down via the the the receiver. I can tell you one thing: this was interesting. This was when I was.

I don't know if this is what you were asking me, but I don't know if you were kind of like implying the ones that have exploded on the microchannel, coils and stuff. I've never seen that, but I do have a story from when I was first coming up was probably six months working with my dad had just started in 2002 ish or something like that, and we went out to do a replacement. What did we do? We went out to go pump something down, so they could replace some bar equipment, that's what it was and what I did was. I put our service gauges on there and so what we were gon na do was.

We were gon na, put our service gauges on there, pump it down and then cut the lines loose, and then we were gon na come back a couple days later after they've replaced some bar equipment and we were gon na hook the system back up so not Knowing you know how things worked was I went up onto the roof? Put the service gauges on the receiver front, seated the valve pumped all the refrigerant out of the low side, cut the lines pinched him off and welded him shut. So that way we could. We wouldn't get any moisture in the condensing unit, then we went to go. Take the gauges off and I realized that I had put the gauges or the high side gauge on the receiver port and front seeded it.

So I had no way of getting the gauges off of the the receiver port because it had pressure behind it at all times. So if you guys understand how a king valve works on a receiver, a typical king valve only has one quarter inch port coming out of it and when you pump it down, there's always good or when you front-seat it. There's always gon na be pressure at that. King valve, or that quarter inch port the only time that there's not pressure at that quarter.
Inch port is when it's back seated all the way so because I had pumped the system down and already cut the system loose and then braised the line shut. I couldn't take the service gauges off and we had to leave him there now at the time. My dad wasn't the most prepared person and he only had one set of service gauges. They were just the analog set of service gauges, so we had to leave him there and then go buy another set and wait until the job was done to be able to get our service gauges back.

So that was something that I learned. You know one of those silly mistakes that you make so okay, Lou stoltz. You said this live stream, isn't live. It's live bro! I'm here we're live right now it should be live, we'd, better, be live, yeah, we're still life, hello.

All right keep going down. What is the best refrigeration leak, detector, JYP HC? I can't tell you which one's the best, but I can tell you the one that I really really like and have used for probably five six years at a minimum is the D text select. That is always the leak detector that I've used so love. It love it.

You know a lot does HVAC paid decent Luke. It depends on where you're at what part of the country here in Southern California and HVAC apprentice can start anywhere from fifteen to eighteen dollars. An hour depending on how good their stuff is and the sky is the limit as to the the top out pay, depending on companies and in little sectors that you go into and restaurant refrigeration, you know you know, experienced Tech's can make anywhere from twenty-five to thirty. Five an hour and then once you get into management, you can make more than that, but you can go industrial.

You can go big, big commercial. You can make more money, there's plenty of money to be made, so it just depends on what part of the country you're in though, because the cost of living is really high here, so we have to pay a little bit more. You know other places you might top out at fifteen twenty dollars an hour, but the cost of living might be a lot lower. So HVAC is definitely definitely a good trade and it make you can make great money, see you later Jean Martinez, alright, Cool, Runnings refrigeration.

If the machine is outside in the winter, you have to adjust the stat okay. So I guess I see what you're saying there imagine maybe a hotel ice machine. That's in a hallway. You know most of the time you know they do make a machine.

I believe specifically for that situation, so I guess I can see what you're saying you know, but that's not a typical installation where a machine is located outside, but I guess I can see why you would have to adjust a bin thermostat in that situation for sure.
