Sensitive location made me think DOD or Military. He's CIA I tell ya. CIA! :-P

I say government location as well. Most likely military installation or base of some kind

I wondered if it was a correctional facility. Yes much cleaner than a traditional restaurant.

I'm going with a prison or jail.

@@theronerd I doubt it, a jail or prison wouldn't be a sensitive location. They'd just schedule him to work on it outside of food service. More then likely this came from the cafeteria of a military, intelligence or a classified section of a defense company.

Less messy that way.

Brazing with propane might not be the smartest thing to do. But it is possible for sure :)

I’m guessing that’s because it’s not as hot as oxy acetylene?

Haha

@@Klokopf52 my plumber brazed with propane

My grandfather was in a nursing home - my mom got on him for smoking outside while on oxygen. He was indignant because he'd only had a "couple" of flame ups! Sigh. The very young and the very old. We will all probably be back there if we live long enough.

Nah its not that dangerous....

I will discuss this on KZfaq this evening 11/2/20 @ 5:PM (pacific) on my livestream, come check it out. kzfaq.info/get/bejne/ia1pmcKem5rGpGg.html

Smaller units can be equally difficult to work on. Because you don't have that many options. But usually easy stuff.

That's the case for any critically charged system

Yea no more that 5.2oz per circuit

Eh, just top it off with a lil propane. Keeps ya in business during slow times.

I try but i miss some of the comments....

You mean WELBILT not Mani right

@@dmiestercommkitchentech3043 no, We are a Manitowoc ice machine CSR and tech support told one of our other techs they won’t warrant the valve if it’s a bad braze joint. I have had them warranty this issue for years, probably close to 100 valves myself in that time but apparently they won’t cover it anymore

@@billymcguffin6038 I know but Manitowoc changed their name to Welbilt over a year ago because of the multiple manufactures they have under their corp umbrella and yea I know all kinds of things are changing when it comes to warranty Thanks 2 COVID-19 if the manufacturer can get out of paying for shoddy work they will and their will be more warranty rejections coming for shoddy factory work

@@dmiestercommkitchentech3043 Oof... Manitowoc changed to Welbilt, famous for crappy household kitchen appliances?

@@dashcamandy2242 like what do they manufacture in household appliances I have only dealt with them for Commercial equipment like Manitowoc, Delfield, Merrychef, Frymaster.....

Wait a small 290 leak didn't decimate the entire building?

I believe this one does it also, exept it stops ont a delay to prevent warming up the box, when cooling demand is present, it first turns on evap fans if there is a temperare decrease beacuase of melting ice on the evap the comp will stay off, otherwise it will come on.

Ive seen a couple brands that do that, i dont remember the names however

Or... he could use any sheet metal as a heat shield/reflector. Might be a PITA but he does enough of them he could easily do that in a few shapes and sizes. Put a wet rag behind said metal to further protect and it won't instacool the joint.

Maybe for the guys that use a tiny ass jewelers tip to braze so they lose all the heat in the metal. Work hot, work fast.

I used to work for Whaleys Food Service in Myrtle Beach SC before Heritage tried moving in

Government regulations pushed for R1234yf to replace R134a, which is lethally toxic. R1234yf decomposes into carbonyl fluoride and hydrogen fluoride when exposed to the atmosphere. Both chemicals are on the "get the fuck out as fast as possible when a leak happens" because just a small whiff of either can cause death or debilitating health issues. Fluorine is the gift that keeps on giving, you can find plenty of videos on why chemists hate working with it. I'd rather have another flammable gas than liquid and gas death flowing around my vehicle. German car companies did R1234yf testing when it was introduced and were horrified that in crash testing it *etched into the windshield* This happened because both of its products of decomposition (HF and carbonyl fluoride) eat glass, as well as many other things, like human bone. It's also interesting that Dupont Chemical is the company behind R1234yf, as well as R134a and R12. And that there is always a big public scandal about how each previous refrigerant is bad for the environment right when the refrigerant is about to have its patent expire and become widely and cheaply available. It's also interesting how Dupont has a revolving door relationship with the EPA, where executives shuffle in and out of both doors. It couldn't possibly be a conspiracy where they regulate themselves and create artificial barriers to keep themselves the only show in town. R134a is currently around $100 for a 30 pound cylinder. R1234yf is about $3000 for the same 30 pound cylinder.

Not sure why. R134a runs at about 16PSI less for the same temperature. I think it's a wash to totally change out components for a refrigerant that's about the same. You shouldn't need to be filling it so availability shouldn't factor in.

@@GGigabiteM I worked previously at a GM dealer, 1234YF was like $1000 for a 10lb bottle, most passenger vehicles only use 1lb, some of the dual evaporator systems used the massive amount of 2.2lb

Not about the engine bay, it’s about the evaporator making it even worse. I would like to see what happens if you let off a spark in a car with 400 grams of propane in the cabin

@@GGigabiteM I thought Frigidaire came up with r12 not DuPont

What happens does it eat the lines?

I've done that on heat pump reversing valves when possible also.

Is that safe on a 290?

@@DANIELSTv if you have never done that before then don't try it on R290. You have to use a very low flame.

That's an issue of the compressor and TXV. R290 can work just fine if compressed to high enough pressure to raise the heat above ambient and expel it and then metered correctly at the TXV to drop the pressure so low it'll absorb the heat. It's a design thing.. saving money or maybe safety but I doubt that. Propane can be safely pressurized to 200 PSI. So I'm guessing money on less metal and smaller compressor that can run on 120V

Its compression ratio, r290 has a ratio like r22.

He is in California so I'd say Nancy Pelosi's chocolate icecream cooler.

@@Anne_Frank00 You said exactly what I was going to comment ... Lol ,,,

Cuz the drier was in the front so change that first i guess.

Every hydrocarbon leak detector will eventually loose sensitivity. Which is why they should be tested regularly and if it is a halfway decent model will have a replaceable sensor.

That is if there is a suspected leak not to leak check he confirmed that he had a leak with the bubbles and the reason was because the sensitivity on the diode lessens over time but still use as a combustible gas leak in the background so if they did not want it used at all then they would don't use it at all
