This video is brought to you by Sporland Quality, integrity and tradition. All right. I'm getting ready to go up onto this roof and uh, I've got my backpack on my back that way I can use two hands going all the way up okay and I've got everything roped and staged. Now this is where people might get a little sketch: I went ahead and have a carabiner on my rope and I have it attached to my belt loop.

Now people may say that's dangerous, but this rope is longer than here so never is that going to put a load on my belt loop and possibly drop and pull me down or anything like that. This is just so I can use two hands to get up under the roof and then be able to rope everything up safely. So it's always important that your rope is longer than the the height of the The Climb You know I usually do 75 foot ropes I think is what this is so that way honestly usually this rope can do pull two things, you can have it hooked to this, go up, drop it down, hook it to something else and still have excess on most of the roofs that I deal with. So we got to get up top and we're going to be repairing an exhaust fan this morning.

All right, we've got a utility Style exhaust fan. This is an older Supreme fan and what happened on this guy was the three-phase switch shorted out and uh, shut down all the fans to the building. This was uh, about a week and a half ago when it was pouring rain. so I had to come out here in the middle of the rain, get it going and now we're back here to replace this three-phase switch.

Now the reason why it shorted out was the top right here broke and the wire or the it knocked out the knockout right here. and the conduit basically allowed that box to fill up with water. So it's kind of a bummer, but we're gonna go and get that guy replaced today. All right.

I'm working in a shadow right now because the sun is right behind me, but this guy right here shorted and the reason why was because this busted and it filled up this box with water. so I was able to dry the switch off I don't like that it I had to dry it off but I was able to dry it off I knocked out this hole down at the bottom so that way if it did fill up with water again it had a place to go and then I uh taped up the switch temporarily got them running also. just so you know I have the power locked out downstairs at the breaker panel so we do not have power here but still always treat it like you do whenever I want to get these uh, nuts loose. What? I Do this guy right here is I Typically just take a screwdriver you don't care about and tap on it like that to get it to break free.

So the new Switch that we're going to use is going to be a little different, but should still work the same I Prefer not to use a switch that has fuses on three-phase exhaust fans because you always run the risk of uh, a fuse blowing in it single phasing the motor. So I got a new three-phase Switch This guy right here should work. Let's get it lined up. We'll get it figured out.

We're gonna have to drill some holes I always do this I carry an impact with me but I have a normal drill because I needed to use my pole saw and I always have to go get it because I forget. All right? So we want one end to come in right here in the bottom. This is an electrical hole saw. It's made for electrical panels and it has a little Ridge on it so it won't let you go too deep.

I Love this thing all right. So we got that one. Now the next thing. this conduit's in really good shape because this is a fairly new motor so we don't need to change it, but I will change the fittings on both of them.

This one not much you can do because it's going under the fan. so on this one we're going to go ahead and come in the top too or the same side. Now this is plastic. If this was a metal box, just pull the switch out so that we don't get metal shavings and stuff in there.

I'm not worried about this. Let's go ahead and see if we can change this fitting. Get one with the gasket. Sometimes you can't get these off.

Let's hope I can. Yeah, it'll come off nice and easy. Foreign, looks good, looks good. All right.

So now I'm going to put this guy in there. make sure the gasket's on it. Good to go. Okay, not right there.

Looks good. See if I can get one of these anti-chafe bushings on here? Oh yeah, Oh no, it won't grab sometimes. you can get them. Oh nope, no, it's not grabbing whenever possible.

I prefer new stripped ends because the old ones tend to be kind of jacked up. It's my ground over here. It's not gravity very well. I can't write about that.

Oh yeah, it's got to go in the back. I Got it all right. So you got to pay attention and if something don't seem right, look into it. I wasn't going in the right spot.

There we go. That's a good ground. Well, actually, this is going to be tight. This needs to go up top.

What was I thinking: make sure that you're not pinching on the insulation of The Wire and I do the run approach so tighten, loosen, tighten loosen and each time you'll notice you can go Tighter and Tighter you're smashing. Down The Wire Stranded So here we go. Now the color combination is not going to be the typical color combination because they're reversing the phases up here. So I'm going to make it black blue red like normal on the inline, but on the out it's going to be blue black red because they're reversing the phase up here.

These ones actually don't really look bad, so I'll leave them the same length that they are my head. Everything's nice and tight and snug wires are safe where they're at. Foreign goes on I Like it. It's actually pretty nice.

You know in the work that I do I don't see a lot of this stuff now. I'm not a huge fan of the plastic, but as far I'll consider this to be like a European style disconnect switch I Like these: I like the idea we I don't think we use enough of this stuff here in the United States or in America but I like it I think it's pretty cool. just got to make sure we get it tight so it makes a water. Tight Seal There we go on off.

I like it and it has when you turn it off you can pull that and you can do a lockout so that's pretty nice. All right rotation is correct so we're good to go. Nice little disconnect switch. um I need to run over here because this exhaust fan right here I'm going to get some information off of it because it's in really bad shape.

It's leaking grease everywhere I Noticed that the holes are wallowed out on the lid and water was getting inside there when I came out here and all these fans are controlled off of one breaker. So I was trying to find the electrical short that caused the breaker to trip and I was really leaning towards this fan because of how bad it is like the gaskets are coming out. It's a lot cleaner now because the rain's gone but before it was a mess there was just grease everywhere. So we're gonna get try to get the information off this fan so we can quote a replacement.

Now this doesn't always work, but there happens to be a model and serial number down here if you take a little bit of a solvent I use rust Buster just because I have it in my thing. it's a penetrating oil really but in lightly brush. you can get most of the Gunk off like stuff off right there and just carefully with a towel. Between this and a towel, sometimes you can get to the model and serial number.

I Wasn't so lucky on this one. I was able to get to it the tags right there but the the numbers are not legible, they're rubbing off. That's one of the downsides, but it's all good. We could just measure the fan.

We have a good Hinge kit I'll just hinge it, measure the wheel height and width, measure the curb of the fan, find out what the voltage is it's 2083 face. find out um, what the horsepower of the motor is and the size of the pulleys. And with all that information and I know the manufacturer of this fan is Ilg. So with that information, I can call the Ilg distributor local to me and they can quote me a new fan.

So I'll get all that information right now. So I hinged the fan I got the dimensions off the pulleys, the motor and the drive pulley I got the information off the motor. It's a three-quarter horsepower 208 three-phase see the inside of it's horrid, full of grease and all that nastiness. Um, came down here I measured the fan curve itself, the wheel size, height, and depth, and I got it all written down right here.

Fan Curve: 26 inches Square Wheel six inches tall by 15 inches wide three-quarter horsepower motor. Ilg is the manufacturer motor pulley 4.25 Drive pulley four inches. So all that information. We don't need a Hinge kit because that Hinge kit is in perfectly good shape.

even though it looks worn, those things last forever. So yeah, we're good to go. This is what I'm talking about that is a fuse disconnect that was more than likely put up when we were in a bind or something I know we did that years ago, but I don't like those because if one fuse blows, then theoretically you could single phase the motor and ruin it. so I prefer not to use fuse disconnects if possible.

but sometimes you got to do what you got to do. But all right, we're going to put this one down, start it up, and get the heck out of here. and uh, give the customer a quote. I wish I could have gotten footage, but it's kind of difficult when it's raining outside to film.

So this was, um, okay. the video that I released last week where I had to change a pressure control in the rain I think that was last week. this was the service call right before that so it was the same day it was pouring rain. I Got an emergency service call and the funny thing about this was this particular restaurant I Know it really well.

Okay, so they have low profile hoods meaning that the hood canopy is very low and it doesn't leave a lot of room for the heat to escape. So they called me and they said hey, it's really smoky in my kitchen and I go are all your exhaust fans down or just one and they said well, it's most Smoky by the Friars and I go Okay again knowing this restaurant I Advise them you guys need to stop cooking. Stop what you're doing, Turn off all your cooking appliances I'm on my way and they were like okay so I get up there. It took me because it was pouring rain and there was snow and everything so it was probably about two and a half hours to get there because of traffic and it was just horrible.

Um so I get up there and I walk in the restaurant. all their exhaust fans are down every single one and they had been cooking for like two and a half hours with no exhaust fans. I Looked at the manager and I Go Stop cooking Right now. So they shut everything down and then I went ahead and found the problem.

Okay because this it's a silly setup, but they have one 30 amp breaker three phase powering their Hood control panel and then there's individual motor starters in the hood control panel. so when the power switch got wet right, it had a path to ground, it shorted and it tripped the main breaker. shut down every fan. So once I isolated the fan that was down I turned everything else back on.

they were able to start cooking and the fryers and stuff and they just couldn't cook where the one fan that wasn't working and then I was able to dry out the switch, get them back up and running. but I told the manager it was a Friday that this happened and I Go! You guys are so lucky that you didn't trip your fire suppression system because they have an automatic fire suppression system that distributes like essentially fire extinguisher stuff. Okay, it's just like stuff that blankets the fire slows it down. it's made by a company called Ansel uh, whatever.

Anyways, it distributes that automatically via heat links that are usually around 500. Degrees if the temperature at the hood filters essentially gets above 500 degrees or right at 500 degrees, I think that's the number I'm not a fire suppression technician, but they have these little links in there and when the links melt at 500 degrees, it auto triggers the fire suppression system. So anyways, I told the manager I go when I called you guys and I said to stop cooking I meant it I go if the fire suppression system went off I tried to explain to the manager I said you don't realize that you wouldn't have been open throughout the entire weekend in probably three days into the next week because when fire suppression goes off in our area, at least you have to have the fire suppressions technicians come out. they have to reset the system, put new stuff in there, Then the restaurant has to do a deep clean because the fire suppressant that they spray on everything makes a giant mess and it's like the whole building has to be deep cleaned.

Okay, then health department has to come out and sign off on the building being properly cleaned. and then sometimes the fire marshal even has to come out and make sure that everything's okay. Okay then more than likely there would be a truck roll from the fire department because when fire suppression goes off, it auto triggers the fire department alert system and you know through their fire alarm and it's a giant mess. So I told him I was like it was a Friday when I went out there late in the evening I said all those people were not going to come out on the weekend.

You might get the fire technician out there, but you wouldn't have gotten the fire marshal, the health department, all these different people and and it's so silly. like I told them I go all that to make how much money like Okay, so two three hours worth of sales like I get it, that's a lot of money and then to a restaurant, it's not just two or three hours worth of lost sales, it's reputation and different things like that. But if they would have had to be closed for like three four days, that would have been huge. You know? So again, you can't fix stupid.

You really can't But I try I try, you know And I was like guys, you need to listen to me when I tell you to stop cooking I'm not trying to be a jerk I'm telling you that you know. Plus on top of that, forget about just the fire suppression system. Those poor Cooks were in that kitchen cooking with no exhaust fans. Health and safety.

Someone could have passed out from smoke inhalation like heat exhaustion. It just dumbfounds me sometimes, right? But it is what it is I was able to get out there I got the system up and running. then I was able to go out there and replace the disconnect switch and size up that other exhaust fan and I quoted it I Haven't gotten a response yet, but I'm sure they're going to approve it so we'll be replacing that other fan here pretty quick. So understanding the sequence of operation I can't stress that enough of your equipment and understanding the operation of the restaurants.

Understanding the locations right? I Know In a perfect world, you're always familiar with the locations you're working at, but it is. You know? sometimes you can't be right. But it's so important for companies to at least have you know a a general area that certain technicians work within. If you're bouncing around to every which location and you have no idea you have no relationship with the management it, it doesn't allow you to the opportunity to be able to give them sound advice in this situation like I tried to give them because I know that location.

if I was just a an on-call technician that had to travel 200 miles to a location that I normally don't ever service, well, you may not have been able to give them that advice. Okay and again, it happens. I Know that service companies can't always have the same technician going to the same restaurants. neither do I I Don't always send the same technician but we're a small company and we have a small service area so all my technicians are familiar with the restaurants that we work on anyways.
