Today we have a cap to their system, that's been given us a problem. We had some motor starters fail, they had an electrical issue and we bypassed them temporarily. That's what you see all these wire nuts, so we're gon na get in here and replace these motor starters today and then, hopefully, uh also gon na make some adjustments of the exhaust fans and speed them up a little bit. Okay, so we've got the new motor starters installed, we're using this one as a contactor, because they're just running two single legs through there and then the rest are used as actual motor starters that monitor the current running through the wires, and you know turn them off.

There's an overload situation. What I want to point out is: I have no power, control, voltage or high voltage in the system right now and what I did was I tripped all the motor starters. If you don't know how to do that, you hold down the stop button, okay on this particular motor starter and then right in this little grey spot right here. When you hold down the stop button, you you flip the little thing over and it'll say t so now it's tripped okay! So that way I can turn them on and what I'm gon na do.

Is I'm going to start with max amperage also, so I don't have a nuisance trip when I start these up and then we'll adjust the amperage as we go. We're also gon na speed these things up. So so that's for rest. So now we're gon na turn.

On main power and control voltage and then turn them on one at a time and monitor them. Okay, so we've got everything running now. We did it one. At a time I had a tech on the roof and we powered them up, checked rotation and checked.

Amp drop. We still have the overload settings maxed out because we are going to be adjusting air flow on these exhaust fans to because they need some more Pole. So what I did was, I got a baseline of the amp amp draw right now and then we're gon na go out at just the sheaves or the motor pulleys and speed the exhaust fans up and we're looking to see these amperages increase and not go over. The maximum motor amps so we're all finished up.

I labeled everything and we set the amperage on the motor starter, so everything's, looking good we're gon na go ahead and close everything up and we did speed things up. So we're gon na come to a follow up and make sure that you know in a couple days that they're smoked or that they're happy with the smoke pole and everything. So looking good so far, so this is the aftermath. I don't know what happened, but we had like a massive electrical surge or something it blew this starter apart.

We had bypassed him a couple weeks ago, so this was just a process of getting all parts and getting time to come out we're good to go now. Okay, welcome to Fabulous California. We have an earthquake shut off gas valve on this building, so I was doing work on a make up air unit. We we were up here and we probably hit this line when we were walking around up here, which is, you know, expected that's the main gas line going into this restaurant okay.

What happened then all the sudden as we're getting ready to leave? Glad that's happened when I was here. They said all the sudden II don't have any gas to the building, and someone mentioned that they had earthquake safety valves. That's this chingus right here. Okay, right on this chingus is a reset button, says reset right here I turned it all the way to the right and all of a sudden, you heard the gas actuate through.

So this thing is a vibration, sensitive shutoff valve, and you know this has nothing to do with me because I don't deal with gas, but obviously you know it happened. While we were here so we had to know how to reset it all right. So this was a return visit to replace some motor starters previous about a week to this video we had a motor starter short-out, we bypassed it temporarily. We actually had two of them short out.

We bypassed them temporarily and once I got the approvals to replace them, we came back out what we did was we went ahead and shut down. Everything, control, voltage and high voltage to the system replaced the motor starters. We maxed out the amperage settings. Then we turned on the exhaust fans, let the system stabilize out.

Then we set the amperage settings on the motor starters. Okay, we also sped up the exhaust fans, so we had to do a minor building balance by adjusting the make up air, also to compensate for speeding up the exhaust fan and then finally, at the end of the video was when I ran into the nightmare of The gas line earthquake valve that had shut off the gas to the building. If you follow my social media, you may have already seen me post about it, but we were just getting ready to walk out the door and the customer brought to my attention. They had already started cooking and they had the restaurant open and then all of a sudden everything shut off.

We still had a guy on the roof and more than likely just us, walking around on the roof, triggered their vibration, sensitive, earthquake, shutoff valve, which I still think there's something wrong with that valve. But I was able to after talking to the customer. I didn't even know that thing existed, but I went onto the roof to kind of investigate the customer mentioned to me something about an earthquake safety device, and I just started looking and I found that earthquake safety valve and I noticed that it said reset. So I reset it and the important thing is, is when I reset it.

I heard the gas go through it. I heard it wash as it went through, but then it stopped and that's important, because the customer had shut off everything downstairs. I specifically asked them shut off every gas appliance when I heard that sound of the whooshing gas going through the valve, then when I heard it stop that was comforting because those valves can also some of them. I don't really know if that particular one does it or not, but I do know that some of those valves can shut down on a High Flow incident.

Basically, so what happens? If you have a severed gas line in the Attic, or something like that? Potentially some of those valves could shut off because of that also so not just because of an earthquake. Okay. So by me hearing the gas shut off that herded me to know that there wasn't some major giant leak or something like that. So then I had the customer go ahead and turn everything on light all their pilots and everything was good after that moment.

I also instructed the customer to go ahead and call the utility out to have them inspect that device, because I honestly don't think it should have triggered that easily. That gas line is huge and III mean. I think you should have been able to run a car into that gas line before that thing triggered. But you know I'm not the utility technician, so I really don't understand how those things work properly.

I would also say too, if you guys notice in the video. That's like a hideous install on that whole entire gas line. I just think it's kind of silly that there's no upper supports on something that big on the gas lines and then also the way that they use the the unit strut channel to kind of support. The gas meter that just didn't seem very safe and very sturdy.

Anyways, I highly suggest you guys consider checking out some of the channels that are popping up right now. I want to say thank you guys very much for watching my video and, if you guys haven't already please consider subscribing to my channel. Okay thanks a lot, and I will see you guys on the next one:.
