Hey there, everybody, how are you guys doing this evening? I'm sorry about the delay. There was a problem and I think, there's still a problem. I ended up creating two streams. I think so there's a few people in here.

That probably don't know I'm in here yet so we'll try to get this figured out. Let me type something in here and then I'll pay attention to you guys here. Sorry, it was a very frustrating thing right now. Okay, so I got a couple topics I want to cover this evening.

Hopefully you guys can hear me loud and clear. If any of you guys in the chat would let me know, I'd much appreciate it, and I will we'll talk about a couple topics here and then I'll try to get to some questions and we will we will get going on this yeah sorry, this kind of Really threw me for a loop right now for some reason. My streaming software wasn't doing it all, but anyways we'll get going with this. So alright um a couple topics I wanted to cover.

You know I released a video today on on the the ice machine that wasn't working properly, and that was a really really interesting one, because - and I want to cover a couple questions about that, because it was a prime example. I had another one of our service. Techs, because this was a new customer for us, so I had another one of our service techs with us just because I kind of wanted to show him what was going on, and I thought it was a really cool training experience for him to be able to See too, because if you guys haven't already watched it, I'm gon na give a little recap about it, but go and watch it after we do the stream - and you guys, you know, you'll see what I'm talking about. But so we had an ice machine call and there was multiple things going on: okay, they had another service tech that was working on it and I'm not.

He wasn't a horrible tech. He just made a few mistakes and kind of created a bunch of problems that I had to trip over to try to figure out what was going on with that ice machine. Okay, what I ended up finding out the cliffnotes of it was that the water caught it was a water-cooled ice machine, so it had a water-cooled coaxial condenser and the inlet and the outlet were swapped, so that was problem number one. Okay, once I corrected that I kind of got excited when I saw that problem, because I was like wow.

That was a really unique thing and I fixed it. You know, and but that wasn't it you know I I didn't get I didn't. I I had the urge to go ahead and call my contact at the particular location that I was working out to say: hey, I figured it out, but I decided to hold off because I wanted to watch the Machine make another batch of ice after I did That I noticed that the machine was a little low on refrigerant, went ahead and talked to management. Let him know what was going on and decided to go and recover all the charge out of the unit, and when I weighed the charge back in then the real problem jumped out at me and it was an expansion belt that was bad on a hoshizaki ice Machine, okay, very, very common problem on the Hoshizaki machines.
When the expansion belts they'll start flooding, it happens quite often, okay and that machine. You know, I don't know, who's worked on it, what they've done, but even machines that I've maintained the entire lifecycle. They have. Expansion.

Valves that go bad, they just tend to start flooding really bad. So my thought was: is that the service tech that previously had worked on it thought I mean again I'm assuming because I'm just kind of guessing as to what his mindset was, and maybe it was I'm thinking. Maybe he thought it was overcharged or something I you know. I don't know, I don't know his exact mindset and where he was going with that.

But I thought it was a really important one to put on film because it really stresses the fact that you need to look at the big picture. Okay - and you know I get these comments from people on the videos saying hey, you know. Basically, you know you're taking too much time on your calls. My company doesn't allow me to do that stuff, okay and that's great that some companies don't, but that's the way that I work.

I take my time. I try to go through it. I try to fix it right, the first time. Okay, that's the way that we do things, and you know I tend to find more problems that way.

Okay, it was, it would have been very easy just to you know, fix that real, quick problem and they say: okay, the machines gon na make ice and walk away, but then they would have call this right back right. Another important thing to is is, and it doesn't even have to be on ice machines when you're working on anything. You need to give it time to show you that it's working or it's not working okay on a hoshizaki ice machine. I take I like to watch two to three cycles before I leave that restaurant or location, wherever I'm at okay, two to three cycles on a hoshizaki ice machine can be quite some time right because if you guys work on any of them like I do in The middle of the summer, when it's a hundred degrees outside a Hoshizaki ice machine, can take like almost 45 minutes for a freeze cycle.

So if you got to watch two to three cycles, each time after you make an adjustment, and that can take some serious time. But sometimes it's just what you got to do same thing on a Manitowoc ice machine on any ice machine. Okay, but pretty much Hoshizaki has pretty much the longest cycle time. So that's the one that it takes a while, and you know I showed in the video too, that I like to take the my notepad and write down.

You know everything about the machine so that we can analyze everything after I'm done, and I find that to be very important too, because we can, you know, evaluate things after the fact all right, I'm able to look at it and say: okay, look at the trend Here, look at what's going on, so you know the point I'm just trying to make is is take your time. You know fix it right. The first time look at the big picture, just like I always say, and let's be thorough about it. Okay, guys.
I'd really appreciate it. If, and I know it would really help Justin Justin my moderators in here and we'll try to get to all your guys's questions, if you guys have them that would really really help us a lot. If you put direct questions to me and capslock, so that way, either Justin or I can get to them, okay, and if we don't get to your guys's question, just keep putting them in there. You're not gon na upset us okay.

This chat Scrolls by really fast, and we really don't - I don't want - have to spend a bunch of time with dead air reading. The chat for the questions that I miss so I'll continue to try to get to them. Okay, you know so there's that I'm gon na address some other questions to that that we have in I've gotten in emails and texts, and I also went through the last live stream. That's something I'm gon na try to do.

I went through the last live stream. It just kind of went over all the chat and you know looking to see if there's any questions that I missed, because I really do want to try to get to your guys's stuff. If you guys have it okay, we only have so much time, but I'm gon na try my best. So let's see so I've got some important ones, but I do want to kind of look at the chat, real, quick right now and see if we're missing anything.

I really don't see nothing jumping out at me, yet in caps-lock, okay, so throw it in there again guys if you haven't already put it in caps lock that way we can get to it and hello to everybody. That's saying, hi! Sorry! I was late. It was just the stream wasn't working, I just still don't even know what happened, but for whatever reason we got to go in now so okay, so I did have a question from someone that sent me, and this is, I think, the second time someone sent me This question and they were asking about pricing: okay, how I go about pricing jobs, how we run things at my company all right, I'm not gon na go into crazy details, because some of that stuff is kind of private okay, but I will say that we are A time and materials company, okay, we bill hourly all right. We deal with restaurants here in our area.

Restaurants, will not let you do flat rate or anything like that. Okay, they have to be time on materials. They want to see the breakdown they want to know exactly how long it takes that's just the way the market is here. I know in some other places I've heard of restaurants dealing.

You know they do flat rate and different things like that, but they don't go for that here. Okay, so we bill hourly, we pay hourly and that's just the way. We do it. Okay, I'm not going to go into specific numbers.

I will say that we're right around $ 100 an hour give or take, and that's pretty much right in the middle of my market right now we have some people in the high 80s and we have some people in the low 100's and we're right in the Middle in there, okay, so we're competitive with our competition, and we do base that. We look at our competition, but we also look at what kind of you know what our expenses are. As a company and different things like that. Okay, I am in no way a business expert.
There are a lot of other guys that cover that topic a lot better. I would highly suggest that you guys seek out tersh Blissett on the service business. Mastery podcast he does. He goes into a lot of the business topics and has a lot of different people that talk about different ways to do business properly in different things like that.

Okay, so I'm gon na lean more towards the technical side with my stuff. But that is how we go and we do you know with our commercial customers with our restaurants. We are net 30, so we do give them credit, basically and they're supposed to pay within 30 days, but if any of you guys deal with commercial restaurants, you know that that just doesn't happen. Okay, most restaurants out there that you're gon na be lucky.

If you get paid within 90 days and that's just kind of something you got to deal with and you got a hound and it's just unfortunately part of the business, so that was a quick one. I had a okay, so I'm gon na attack this one right. Now so Shawn Mac asked, if I buy extended for your compressor warranties with all your knee condensing units. No, not necessarily it depends on the customer.

I have one customer that specs that they want me to sell them a for. You know an extended warranty on every single compressor, so we do that for that particular customer, but other ones they don't want them, so it just depends on each customer. I mean, if I have my choice, sure I'd sell them a. You know warranty on that compressor because it's an extra sale basically and it gives them peace of mind.

So I don't think it's a bad idea, but it also depends on the supplier that you're buying the equipment from because I do have one particular supplier in my area and their extended warranties are ridiculous, but then I have one supplier that self finances their extended warranties. So basically, they have enough capital to cover the cost and they don't use an insurance company or anybody to handle their extended warranties. So it all depends on the supplier and who you're going through okay. But I'm not going to go with an aftermarket third-party warranty company or anything like that.

I'm only gon na get them directly from my suppliers, because if I'm gon na sell something, I want to be able to take it right back to the place that I bought. It from to get a warranty on it, so that's just how we roll on that. Okay, let's go into here and see what I'm missing missing too much. Yet I am working on something new, I'm not going to give too many details, but well I mean I I have been for a while working on a podcast and I'm not gon na release it until I have a bunch of different episodes.
So I have been working on that, so that is going to come out soon. I just had a guest on, so you know we're working on that. I want to build up quite a few episodes, so I'm not basically living week to week having to record a new podcast all the time so, but that will come eventually, so you guys will be seeing that coming through and I'll make sure I announce it on All the different social medias and different things so that'll be coming up soon: hey there Rick how you doing but Rick with Northwest Ohio, HVAC videos, that's down on the bottom right there, okay! So one thing I wanted to point out to I: this is really interesting. So I was at, I was emailed by Erno.

There was a comment on one of my youtube videos and it was a guy asking me if he thought he saw me in a training class a while back and he was curious. If it was me - and it was, but I want to point out to you guys - I've had that come up a few times where people or in supply houses or something. And then you know I. I may look like an from the look on my face, but I don't mind if people come up and say hey, so if you guys see me any you guys are local or anything like that, and you see me come say hey, you know, stop me.

I just have that you know look on my face all the time. You know that makes me look like an basically, but I don't mind talking to people and saying hey to people. So if you guys do see me out in public, stop me and say: hey so, do I have lots of customers that buy their own equipment and that was Kane. I've astir? Yes, I do, unfortunately, that's something that you have to deal with when you're dealing with commercial restaurants, especially chains yeah.

They get big national accounts and you know they have national accounts with all the major AC manufacturers and refrigeration equipment manufacturers, ice machines, regions all that good stuff. So I do have a lot of customers. It's one of those things you have to evaluate it. If I only you know, if I had a chain restaurant that I only did you know two of their restaurants, then I don't know if that would quite fly with me, but most of the chains that I do you know I do ten to fifteen.

If not more of their locations, so it's beneficial for me to still just sell in my labor and extra materials. But yes, I do have a lot to buy their own equipment. So fortunately they, let me do the installs on the equipment. So you know that does help a little bit.

I mean it's, not the perfect business model. You know, but you kind of kind of roll, with the punches when you're in my little niche of restaurant refrigeration. So just one of those things: okay, so, okay, I'm going here, do you? Okay? So how do you use a magnet for the scylla node? Well, I mean it's a cylinder right. I don't have to.
I have one sitting right here. No, I don't. I had one, but I must have put it in my van, but essentially a solenoid valve is just a valve that has a magnet or magnetized plunger on it and when you put the solenoid coil on the top, it creates a magnetic field. Then it pulls the plunger up.

So with that being said, if I have a perfect magnet that it hauls a whole drill through the middle, we call it a cylinder, eyed magnet right. We set it on top of the coil and what it does is it opens the Silla Knight valve okay. I hope that's what you're looking for. Hopefully, I answered that correct.

If there's, if you need more context than that, you can put something down in the chat or you can email me more, but I use them quite often and they're actually very important, because when you're doing a proper evacuation or recovery on a system, you want to Reduce the restrictions and if we've got a cylinder, it's closed down the line and we're trying to recover. You know the refrigerant we could have refrigerant trapped on one side of it. It gets especially tricky when you're working on ice machines, because ice machines can have three four solenoid valves inside of them because they can dependent if you're, working like a Manitowoc cool, vapor machine, you're, quiet, cube machine. You know you can have two hot gas valves, one for each evaporator.

You can have a liquid line, still annoyed valve, you can have all kinds of stuff and then you can put check valves in there to it. So you got to be very cautious and make sure you read manufacturer's installation and service instructions when you're working on a particular piece of equipment. So you know how it works. But if it's just a straight forward, walking cooler like I'm gon na be doing a walk-in cooler install tomorrow and when it comes time for the nitrogen purge before we braise I'll, put Silla night magnets on the solenoid valves.

Actually, this one's going to be electronic expansion valve. So I can't do that on that one I'll have to energize the coil, but you got to read it. You got to eliminate those restrictions, so you're gon na you know either turn on the electronic expansion valve or put a magnet on the solenoid valve and recover and/or vacuum. So, okay, okay, so Aaron, Himes Hames! You said you sometimes you spoil in there in Austria.

I'm su me in Australia and you have a lot of trouble with their sight glasses leaking. Have I have no? I have not. I have not come across a spoil in sight, glass leaking in a very very long time. I haven't come across any sight, glasses leak.

Well, no, I have, but I prefer to use spoiling pretty much spoiling everything, because I have a really great luck with their their products. I've had some people reach out to me and say: they've had some stuff with dryers and different things, but no I've had nothing but great luck with spoiling products, so I loved their sight, glasses. I would say one of the only things I'm kind of bummed out about their sight, glasses, especially their sweat ones. The ones that you have to braise in is that they're like a copper coated steel.
So when you go to sand them, it's very easy to sand off the copper and or if you're, trying to braise them in it's very easy to overheat, the valve and then, if you're, using sill Foss, it won't bond to the the steel that you've exposed. Basically, okay, so you there is a technique to brazing in a spoiling sightglass and you kind of have to ignore some of the the rules that you learned about brazing. Maybe I can get that on a video one time and kind of explain what happens there, but there you'll actually come to find that there's a lot of products out there, even like on a Copeland compressor. You know this.

The service stubs sticking out at the top of a Copeland compressor typically are sometimes they're like a copper coated, steel too, so you it's very easy to sand the copper off. So you got to be cautious about that kind of stuff. Okay, what do I know? What do I say, apparently I say a lot Jason. You know someone's someone and hey to each their own.

I appreciate everybody's feedback on my videos and stuff and I appreciate everything, but I got a comment that just made me laugh today. The comment said: can you talk less in your videos, please? I was kind of blown away by that one. I really don't know how to take it. If you're in here I'd love to hear more context.

Whoever wrote that, but apparently I talk in my videos too much so I was supposed to talk less. I don't know okay, so I thought that was a funny one. Let me see what are all the reasons? Ok die for truth. You said what are all the reasons you will have equalized pressures on a system.

I kind of need a little bit more context on that. Ok, but I mean equalize pressures on the system, means that I mean it just means you got equal pressures right. So if your compressor is yeah, I kind of need more context on that one, but I honestly would like to oh, hey Zacks. Thank you so very much dude I keep on talking.

It is ok. I really appreciate that Zack died for truth. I kind of need more context on that, but so either put it down in the chat I'll, try to get to it or send me an email to HVAC our videos at gmail.com, and we can talk about it a little bit more. I need to move something on over here, all right cool.

Could I break down the ice machines into an too long of a freeze cycle? You don't know about them: big, J's BBQ. Thank you very much man. I'm gon na go back up. I'm gon na answer.

Your question real, quick, big J's, my thoughts on the new refrigerants coming in via the EPA in 2020 Demetri. Thank you. So much personally, you think it's pointless well, whether you believe in global warming or not, there's nothing. We can do about it.
Okay, 2020 EPA regulations are coming, whether we like it or not. So it's something we just got to learn to deal with, but I will say for us: in California those 2020 EPA regulations are already coming into effect because the state of California already passed the law. This past year January, 1st, where we're not allowed to use certain refrigerants, especially our for for a which is one of the 2020 regulations coming out, so we get stuck with it a little bit earlier, so whether you believe in it or not, it's just something. We got to deal with, it is what it is.

You know you know yeah, I'm not even gon na, I don't know, send me an email, we could talk more about it. I don't want to waste everybody's time because I'm not like the smartest person when it comes to politics and different stuff, but yeah. It's just one of those things you just got to learn to deal with guys that are putting in these super chats. Well.

Thank you very much. I really appreciate it. So, okay, let me go up into here. I'm sorry, I'm missing questions here guys.

So what are all the reasons when it's running, oh okay, so die for truth. You said what are the reasons why a system would have and equalize pressure when it's running normally well, first off I'm gon na you know, I say that I make my videos off of the mistakes that I've made right so make sure that your manifold valves are Closed on the ends, okay, you know the valves that you open on the left and the right of the manifold to you no charge or do whatever don't be like me, and leave them open and wonder why the pressures are equalizing in the system. That's a big one and then other than that, your compressors, not pumping dude. If the compressor has power and your pressures are equalized, there's something wrong because your compressor should be pumping.

So, okay, can I explain TXV hunting a fellow technician and I watched it happen today, but weren't too sure how to approach the problem. It really has a lot. It depends a lot on. What's going on your system, okay, we need to know you know.

Is your expansion valve sensing bulb mounted properly? Is it insulated properly? You know, there's a lot of things that can affect the way the system is operating and causing hunting, so you'd kind of need some more more details. It's kind of like a shot in the dark for me to jump onto that one. Okay again, I think that's one that you might want to send me an email on and I can get some more context and then either I can address it in an email or address it in the chat next time or something like that. Okay, so HVAC our videos at gmail.com, and you know we can talk about it more and I can get some more context for those of you guys.

Also to that that have questions I don't mind and I try to get to as many as possible, but you guys are more than welcome to message me on Facebook. Direct message me on Instagram that kind of stuff and I'll try to get back with you or email me and I'll try to get back with you and answer your guys's questions that way too. So all right, I'm going here, is there a solution? Additives, possibly for a stuck TXV die for truth is asking that ok, there's all kinds of additives that people say will do things. The most popular one would be AC.
Renew AC, renew used to be a product called zero ice new Calgon, I believe either they changed. The name or they bought it and changed the name, but now it's called AC renew. I have not had any luck with that. I've used it probably two or three times and and again I'm not a fan of additives guys but has been a couple instances where a system was being thrown away and the customer wanted to do something to try to make it work until they could replace it.

And will put an additive in there. I really don't see any will any luck from that stuff. Ok, I've heard from you know other podcasts and different things that some of these additives they aren't even really anything other than like certain oils and different things. So not a fan of additives and no, I have not had any luck getting an expansion valve to unstick something's plugging it up.

So you need to clean up your system and replace the expansion above unless it's you like a refrigeration, you have a screen that you can clean, but getting a valve itself to unstick, not so much okay. I will say, though, that sometimes you can take an expansion valve apart depending on the brand, if it's like a spoilin expansion or if you can take those things apart. I'll even tell you a hack that I've done before you know it's one of those things, but I've taken an expansion valve apart because it was in a really hard place to braise in a new one and just replace the guts pull the whole valve apart. Powerheads stem and everything and just put the new valve basically because it was the same valve and piece everything together.

So I didn't have to braise in a new valve done that before many times cain i've astir have ice. Have I been seeing problems with heat craft evaporators leaking in the tube sheets for years? In no, not not yet I'll be honest with you. We used to have a lot of problems with like the rustle and the cold zone. Evaporator is leaking at the the expansion valve distributor bell on the expansion valve, but no, I haven't really had a problem with the heat craft ones.

I have seen other people posting on social media about the heat craft ones, having leaks and the micro channel condensers a lot, but I've yet to see anything with that. So not not myself. No, oh! That's a good one, big J's BBQ! How many installs do I come across, where there's a callback do to them installing crossed wires, and/or wired backwards? I've seen that many times, especially on some of these manufacturers, such as like Cole pack or RDI. I've done work for them too, but I see some of the installation companies they've used and some of the stuff has been so twisted and inside-out.
I think the biggest problem that I see is when you have a new start up and you have different trades doing different jobs. Okay, here in Southern California, we're allowed to do the electrical for our device, I'm not supposed to really run to the panel. But but I'm talking, you know like a walk-in freezer, install I've seen jobs where they have electrician, do all the electrical and it always gets messed up. You know the refrigeration guy just do the piping for the refrigeration and then they would have the plumber do the drain lines for the walkin coils.

I know in other areas: that's how you do it, but out here in Southern California. That's not how we do it. So when they have the electrician do that stuff, it never gets wired right, it's always a mess. So I have seen that and I don't mean to talk crap about electricians and stuff guys.

It's just maybe just the particular electricians that are working on these new installs. Maybe they aren't using the greatest ones or something. So I don't want to talk crap. I know there's good electricians out there too, there's bad air conditioning and refrigeration companies too, just as much as there's bad electricians and plumbers.

So I'm not singling out any one trade saying that there's a problem, so, okay, I'm gon na, go to some of my topics that I have on here and let's see I thought this was a good one. So someone had asked me a question earlier. If a grounded, compressor always means that there's gon na be acid in the system, okay and the answer to that is no okay, there is the potential, especially with the newer oils and the newer refrigerants with the older refrigerants that had chlorine in him. I know that it was a much bigger problem and I had like mineral oil.

You could have acid present in the system if there was a grounded situation. Okay, but on the newer refrigerants that don't have chlorine, it is possible to have a grounded compressor with no acid. Okay, you could have dirty oil burnt oil. That's totally legit right, but if there's no moisture present in the system with like pol, you know, you really don't get acid buildup okay.

So it's very important when you do have a grounded compressor that you do a proper oil test. Okay, whether you use those little cheap things that you push on the Schrader's, you know, I don't know how well those work. I know the proper way to do it is to do an oil sample or you get a sample the oil and then you analyze it and you add it to different chemicals, and it reacts telling you if there's acids and different things so, but I thought that Was an interesting one but yeah there's it's not always necessarily acid. If you have a Burnout.

Okay, so just keep that in mind - and you know the old-school way. This isn't necessarily the right way. You still need to do an oil test, but a lot of times on a burn. You can usually smell it so as you're recovering the refrigerant.
If you know, if you can actually smell the refrigerant, you can usually smell like a tiny, a little bit of a funky smell and that's the burnt refrigerant usually means that there's something going on there, but okay, reefer tech mark you said: do the units? Do you the units that any of you work on have automatic phase reversal well, Reaper tech mark on a lot of the equipment that has variable frequency drives on it? It will correct phase rotation. Now I don't know if it'll hat like I don't know if it'll correct phase rotation while it's running, I don't know about that, but yeah a lot of VFD drives will have phase reversal in them and it will check for proper phase rotation and correct it accordingly. So with that being said, if you do a start-up on like a packaged unit and it has a VFD drive, you know the old-school way of checking phase rotation without doing it properly would be to go. Look at the indoor blower motor and if the indoor blower motor was running right, there was a very good chance that your compressors were wired up a B and C the same way as the indoor blower motor.

So therefore you are correct. You know you had the right rotation, but it is important that you actually check rotation now, because, with the advent of VFD drives and our equipment, it's possible that the VFD drive corrected the phase a reversal, basically so that the V you know the indoor blower motor Could be running in the right direction, but the compressors could still be running backwards. That's one of the things that I really like about the field piece. Sc 660 clamp meter that I keep in my bag because it has phase rotation on it and granted.

It's probably not the like most high-tech fluke meter, that does phase rotation, but it gets me in the ballpark. So basically you grab the meter. You you check line voltage to the unit and you hook up line one to line two and then you you go from line one to line three and it tells you a b c or c ba. You know to tell you that things are wrong or whatever.

So I do like that, but it is important that we check proper phase rotations, so our rides, the key to therm controls are my customers liking the benefits cane, I've astir? So yes, and no it's hard for me, dealing with commercial restaurants, I'm sorry chain, restaurants, sell them on energy efficiency stuff, because a lot of times my contacts that the restaurants aren't the bigwigs that are concerned about energy efficiency. When I'm dealing with like a regional facilities director for the most part, he just wants the thing working. So if I go to him and try to say hey, I want to quote this job: it's gon na cost. You know two thousand dollars more because I want to put this high-efficiency thing on there.
That's gon na save you money a lot of times that might go to deaf ears on the regional facilities level. You know if somehow I can get an email up to the higher-ups they may jump on that, so are they seeing and enjoying the benefits? I wouldn't say that that, on my level of communication with the facilities Department that they're enjoying and no, I think that my level of facilities most of the time, the guys just see money and they just want things working for the cheapest, don't get me wrong. They're not you know, I choose to work with customers that like to spend money and do things right, but as far as selling someone on an energy efficiency upgrade and a chain restaurant, that's a really really hard sell. Okay, unless you're dealing with the corporate office and I've never been able to bridge that gap with the correct person at the corporate office to get energy efficiency sold to them.

Essentially so, okay VFD Craven dick hurts, you said VFD can be wired single-phase 208 in to power three-phase out to equipment. I guess the right VFD right. If it has the right amount of capacitors in it. I guess I guess that's possible.

I've never seen something like that, but I mean essentially you can yeah. I guess, because what I would have to do it have to convert it to DC right yeah. That's interesting! I'd have to do some more research on that, but I I have heard about that. I don't I don't have a lot of knowledge and talking about that, but yeah.

That's interesting! I'll have to do some research on that, but but thanks for bringing that up, I'll actually write that down: okay, okay, so just in PH vc recommendation for upgrading from beacon it II. Let me correctly say what he wrote from shitty beacon, one systems with two evap s: -- kita, therm, back to t --, xv and mechanical switches and other options. So i mean personally, i would like to stay. I would I would try going to kita therm and seeing how you like that.

But you know one of the downsides that we have in our equipment is proper installation practices right and a lot of people. Don't follow proper installation practices so even on Akita therm system, you know knowing where to properly place the probes in the evaporator for the coil sensing is very important. You know the higher you place on the better for defrost termination and different things like that. So it's important that that you know where to put that stuff and if you don't, then it's going to cause a lot of headaches and people are gon na get frustrated with it.

So, honestly, I have no experience with the beacon systems. I've worked on the. What do they call it? The quick response controllers, the qrc, which is just a dumbed-down beacon system, that's their new model that they came out with before they came out with the intelligent, which is the new one that they came out with they're coming out with stuff to Faust's or too often. Basically, but I've worked with the qrc and I really haven't had too many problems other than improper settings and a few few factory issues, but nothing major.
But I've heard I've heard good and bad about the beacon systems, especially the older beacon, like you said, the beacon one. I've heard better results about the beacon two, but I would would like to say: I'd go to the kita therm products, but I mean mechanical is true and tested right. It works so I mean if they just want a working system and don't want to have all the fancy bells and whistles a mechanical is a good way to go because it works, and we know how to fix it right. It's easy to get parts for mechanical.

Changing out a headmaster tomorrow, any pointers obviously you're going to recover the gas out of the system, and then I what I would highly suggest you do any time you read the installation instructions. Is you want to clip the tip on the headmaster valve before you put your torch to it, because the the refrigerant charge in the dome of it can be a problem? So you want to clip the tip after you've recovered all the gas before you unswept the valve, so that be the only tip. I'd give you other than that make sure you protect the valve with like a heat compound or something like that. To make sure you don't overheat it and make sure you pull a proper vacuum and proper liquid dryer, of course, okay, so purge with nitrogen all that good stuff, I would also argue you know with headmaster valves.

I will make a bold statement and I think that most of the failed headmaster valves are going to be because people aren't following proper refrigeration practices and stuff is getting stuck in the valves and or when they're installing them. They overheat the valves and so the mechanics inside of it have a tendency to get stuck, especially when you're dealing with spoilin valves. I don't have a lot of bad things to say about the spoiling had master valves. I've had good luck with them, so, okay cool all right, let's see what else? Okay, so I'm gon na go to my sheet here cover cute couple more things, Oh got to point out my flaws right.

I want to want to tell you guys. I made a big mistake and, and probably only about four people caught it in my last, my video that I uploaded on Friday right. So I uploaded a video on Friday, where I installed a new evaporator and the beer walking equipment that I condemned the previous Monday before right. That, let me tell you, too, that that work was actually done all the way in last year.

Yeah, I want to say it was done in like November December, but I'd been sitting on that video because it took a lot of editing and different things and piecing together, different cameras and stuff, and I was kind of slow and lagging on it. So I finally got it edited and so that equipments been running for a couple months now, and someone pointed out really actually four people pointed it out that when I was prepping my coil before that I installed the wrong nozzle on the expansion valve and I went And reviewed the footage and sure, as I did so, what I was supposed to install was a 1/2 nozzle and I installed a 3/4 nozzle on that. So I just want to point out. I make mistakes too.
You know that, like I always tell you guys that these things that I say in my videos are usually from me making mistakes and having to learn from them. So hey, hey, Ralph! Thank you, so very much man. I really appreciate it so, like I said you know just like everybody else, my stinks too so I I make mistakes and I'm human. It happens.

Ok, so in that situation, the nozzle that I installed is a slight hair too big. I'm not really going to do much to correct it, because it's not going to make that big of an effect I'd be more concerned. If my nozzle was way oversized, you know or way undersized, but just going that half to a 3/4. It's not going to be a big deal, but I do want to point out that I did make that mistake.

So all right Chris did. I cut the compressor open. Yes, I did yes, I did I cut I I haven't me I I do have some footage of cutting open the compressor from the beer walk-in a couple weeks ago, the one that had the single phase overload protector when it was three-phase. I did cut that compressor open.

I am gon na piece together a video about it, but I did post pictures on social media. If you go to my facebook page or my Instagram you'll see him. It was very interesting. I am gon na say that that compressor, that valves inside of it looked like someone shot it with a 45.

I mean the valves were just blown apart. It was very interesting. It looked like it was like a liquid slugging thing coming back and blew the valve apart and then a piece of the valve got stuck in there and the piston was even damaged because it was pumping on that broken parts in there. But as far as the single phase overload, I do have to say, if you guys remember that video the single phase overload on that compressor is correct.

That is a very strange compressor. It has a different winding than normal, so from the factory on that compressor. If you own out the windings the they will not all three equal the same, it's it's something I was doing a little bit of research on it. It's called a Scott T, motor winding and one of the windings is going to have a higher resistance value than the other windings.

So that is normal, and that was reflected in my video. But then also I was tripping out because it has a single phase overload protector. Well, I was going through the manufacturer's information for that compressor and they actually call for that single phase overload protector. I did open up the compressor and look at the windings and they were on the inside only monitoring with an overload two legs so for whatever reason it probably had to do with that Scott T whining they had an external overload just on that higher resistance leg.
So very very interesting, one all right everyday tools that I carry on myself, Ralph the only tool Ralph Holley Lee asked me that the only tool I carry on myself is a flashlight and a pocketknife other than that. I keep them in my bag and I have a Vito backpack that I carry around with me and that basically has all the tools that I carry with me every day, but I don't carry like a six and one in my pocket or anything like that. I don't carry a multi-tool, I just have my pocket knife and my flashlight and then you know occasionally you I don't know if you guys have seen. I don't think I show it very much, but I do keep a mirror and my pocket and a marker.

I don't even keep a pocket screwdriver in my pocket anymore, so a DJ sub err. Do I require a three phase relay on three phase systems shut down the system. If the phase rotation is wrong. Well, there there's some holes in your question there, but yeah.

I kind of get what you're saying so you know you should have three phase motor protection, I'm gon na kind of answer. What I think you're asking so you should have three phase motor protection. So if you lose a leg it it basically doesn't single-phase the compressor, because that can be a big problem. So you should have single phase.

Protection is what we call it, but a lot of times motors don't have single phase protection, so they do have an overload inside, but it won't necessarily. So the theory is, is that if you single-phase the compressor, the overload is gon na cut out, but a lot of times. I still see problems with compressor that I'm in single phasing for too long and they'll still get damaged, even if they do have an internal overload. So they should have a single phase overload on the outside one that monitors single phase conditions.

Companies that make those I'm trying to think of the name, I can't think of them, but yeah I'll, think of in a minute. But there is companies that make them. But it's not something that people install and their equipment very often, and I will say that when we deal with any kind of electrical equipment, a lot of the problems that we have, especially with like variable frequency drives and different things is because we don't have proper Power conditioning, so we don't have proper monitors that are watching the power coming into that particular piece of equipment, and I think that's a fatal flaw that we have, because in our industry, we're bringing in all this new technology - and we have all this fancy equipment. But we don't have anything monitoring the power.

So in my experience with the restaurants that I deal with, we, you know like it. Had these fancy exhaust systems made by male Inc that have variable frequency drives and all that stuff that speed up and slow down and they lose motor starters every three years and in my opinion, if we had proper power conditioning on that equipment, we wouldn't be losing Those motor starters or variable frequency drives as much you know. So it's just one of those things where we don't do enough to protect our equipment. When you get into big industrial stuff, they have a lot better power conditioning because their equipment costs a lot more money and they're more concerned about that.
But when you're dealing with restaurants most of the time, they don't really care too much about that stuff, even though they should hey Justin Bieber. I would say it's funny because I was going through the comments and I noticed that you had posted that you got the new s, man. What are you thinking of it? But okay, so yeah, I see that's your comment. I just saw your name but you're, loving it huh, that's cool.

Have you been using the wireless features in it? Has anybody else in the chat? Got the Newfield peace manifold, that's capable of working with the wireless JobLink probes, okay, I'm gon na. Let you guys answer that, let's see! Oh, I want to post something in here. I know he's not gon na he's, not asking me to do this, but I just wanted to post it to help him out. Is this post right here, ctrl C, let me post it right here there you go if you guys haven't already copy that link that I just posted in there and subscribed to Zacks new YouTube channel he's trying out something new where he's not posting about HVAC is More or less talking about different stuff on there so check it out and that's stack with HVAC shop Talk.

So okay appreciate as eck just want to you know. I see that you're trying and I know that Zack wasn't really gon na try to push that on his his other channel. So I'll put it up in here. So how do you troubleshoot a current relay Ralph? That's not something that I'm gon na be able to cover in here.

I will say that there's a great great explanation of current relays and how they work in the refrigeration for air conditioning technology, fridge eration for air conditioning technologies book by dick wars. It has a great it starts at step, one on why we need a current relay and then at all, I'm not gon na be able to explain that all to you off the top of my head right now. I understand how they work and I can understand how to troubleshoot them, but telling you exactly how to do it over this stream is gon na be difficult, but pick up the book for any of you guys that are in commercial refrigeration, even if you're an experienced Tech pick up the Burke commercial refrigeration for air conditioning technicians, bye, dick wars. It will explain so many things and help to fill in a lot of gaps on things that we know how to do.

But maybe we just don't know how to explain them. It really fills in those gaps and I'm gon na grab the book real, quick and show it to you guys probably need to put my bookshelf a little bit closer commercial refrigeration for air conditioning technicians, bye, dick wars. You can it's published by sin gage. You can sure you can go to sin gage brain calm as their website.
I'm sure you can get it from Amazon or something too so definitely pick up that book guys. It will really really help you with that. Okay, let me go up into here and let's see, what's going on Zack your channels for therapy hey, I was just working on a podcast episode. Again, I don't know if anybody heard, but I was talking about.

I am working on a podcast, but I want to get a bunch of episodes before I release it and I was working on one today and we were talking yesterday and we were talking about therapy so very interesting. I I will go a little bit into it and I don't want to get all mushy and stuff like that with you guys, but I did go to therapy because I had mental problems in my head and I still have mental problems that you can see. The on my face, it has to do with my mental problems, but therapy and seeing a doctor really helped me, so I'm not afraid to admit it. Alright, on the mechanical defrost timer, can you adjust the length of a defrost time? Yes, you can gear mo a mechanical timer yeah.

It should have a little pin on the outside everyone's different, so I don't know which one you're working on you're. More than welcome to send me a picture in a email, and I can talk to you more about it. But yeah. You definitely can adjust the length of defrost time and then a lot of times too, depending on if it's a walk-in freezer a reach-in freezer, they might have electronic defrost termination built into it too.

So I've got some videos on. I explain how to adjust the timer, but I explained how the timers work so I think there's a video I have titled walk-in freezer defrost electric defrost explained you may want to look that up on my channel and it explains how electric defrost works. But again, it's not gon na tell you how to adjust the timer so jeez solace. Thank you, so very much man.

I really appreciate you guys. These super chats are awesome, really really appreciate it. Okay, let's see hey Isaac, Isaac is deaf, hvac are SoCal, I'm gon na type hi to him. Guys.

If you guys don't know, Isaac is deaf, so he can only read what's in the chat so, but he is a service technician here in Southern California and I'm gon na say hi Jon real quick. So I don't mean to ignore you guys here: hi Jon there. Alright, which i think is crazy, because to think that Isaac is an HVAC tech and deaf, it just sounds so interesting to be able to troubleshoot. I mean you got to think he's got a he's got to know you know and, and his other senses have to be heightened right to be able to hear because he can't hear things so he can only feel in touch and very, very interesting.
Ok, so, let's see Thank You, Guillermo really appreciate it, but alright, what's the easiest way to match evaporators to condensing units for equipment that is not marked, and you have never been there before for refrigeration units, drawers, pans and drawers well in in Doug Brown. That's a really good question, so you have to understand properly sizing, equipment, right and sizing equipment is it's there's a fine line with oversized and equipment and under sizing equipment. There's a lot of factors to look into so when you're sizing equipment. It's just like a house.

Doing a load calculation you've got to start with your load calc, depending on the reach in now on, reaching coolers and reach and freezer well reach in coolers, especially especially like prep tables and different things. Our evaporators tend to be oversized and they're oversized for a reason, because we need to be able to bring that box temp down a lot faster. Ok, we tend to run higher TDS on regions, especially manufactured equipment, from like true and Charlson, and different things like that. Those guys are going to be running like 20 to 25 degree, evaporator tds on them.

Ok versus you know like a walking cooler that is mainly dependent on the what's being stored in it sized with, like a 10 degree, evaporator TD. So it's very important that you're you you're gon na start by doing the load calculation on your box or at least placing coils in your box. Okay, again, you don't want to oversize those and there's a lot more to this, but I'm gon na give the cliff notes of it all right, so you're gon na start with your evaporator size. Once you know what you want in your evaporator once you know how many fans you need to move the air around the box and that that's a very important thing, because a lot of times on reaching coolers, because we only have so many options, we end up Sizing via the fans, so we end up adding fans or you know coils that have more fans, so sometimes they might be oversized BTU wise, because we need the air movement inside the box.

But you got to start with the evaporator. So once you start with the evaporators, you add up all the BTUs and then you base your condensing unit size off of that. Okay, once you have your evaporators and once you know how big of a condensing unit you need. Typically, I don't want to go.

I typically like to be about a thousand BTUs over on my condensing unit and again these are rules of thumb. I realize that if you go through a proper training class, they're gon na say to get the evaporator and condenser as close as possible. My thing is: is I like to see a little bit of space, so I don't like to go under. I don't like to you know I, like my my condenser to be at least a thousand BTUs bigger than what's needed for the evaporators, and I don't want to go.

You know you really don't want to go too much bigger, because then you might not bring enough suction gas back to that compressor. Okay, cuz a lot of times. Our compressors are such and cooled right, so we need the proper amount of gas coming back to them, but you really need to look at your evaporator load.

    New Regulations in Denmark 2020 if they get approved are… Maximum charge 2,4 kilo R410a, 3,5 kilo R134a/R448a/R449a, 7,4 kilo R32 .. The reason that you don't see R404a is that the GWP is 2 high and can't be used.. At the moment the government is trying to outface R404a, the method they are using is GWP tax.. 1kg R404a cost 450$… R22 is banned, and has been for a long time.. I am not allowed to 2 open up the line system 2 fix it.. I think the plan in Denmark is that, every unit most be Co2..

    I have herd that a three phase motor will run on single phase if you use a VFD. I have never done it myself
