R-290 REFRIGERATOR NOT WORKING
Вставка
- Опубліковано 15 вер 2024
- This was a service call on a R-290 refrigerator that was not working, I found that the unit had a bad low pressure control that was not letting the unit turn on, I replaced the control and the drier and the unit is now working properly.

For those wondering, R-290 is pure propane. As mentioned it does not have an odorant like the stuff you'd usually use on your bbq because that would become a non-condensible and hinder the efficiency of the refrigerator or AC unit the gas was used in. Aaanyway. The reason it's safe to vent into the atmosphere is because unlike R-22, R410A and other HCFCs, R290 doesn't cause problems such as ozone layer depletion when it is vented into the atmosphere and is not potentially toxic to life... it just gets a little explosive if you keep it captive with a spark nearby...
Also, have a funny thought.. If Hank Hill was a HVAC guy... I'm 100% certain he would refuse to work on any refrigeration systems that didn't use R290 as a refrigerant... He would also probably recover the charge so he can use it later on for his barbecue...
Here is a couple tips, When working with R290. You won’t be able to easily move a R290 Refrigerated Case. In a difficult case, You can use a small recovery tank made for flammable refrigerant. Put the small tank in a vacuum and release the refrigerant into the tank. Take the tank outside in safe location and cut the R290 loose. Repeat step if all refrigerant wasn’t removed. They did make recovery bags for refrigerators, That will also work for temporary containment to release R290 outside enclosed building. Good Video.
I never get bored watching a professional work. I'm an 66 year old Boomer that's been in the trade since the 70's. 50 years of work experience & still pick up a few tricks from other professionals.
Never stop learning.
The big deal here is VRF, variable airflow, rectifier and control boards. Systems having state of the art inverter techs confound a lot of techs. The biggest problem are these systems need surge protection for dirty power areas or lightning pulses.
AN HOUR VIDEO ARE YOU KIDDING ME!!
Thank you sir 👌👍
Loved it
Damn right STOOOOOPIDDDD!
That's where the details are as simple as it is..
Haha I only needed an answer that was 45 seconds of the video.
I was one of the guys that hung on till the end, not because I'm that kind of 'Fan Boy' but because the content was on point. The stressing of safety when working on R290 systems paired with the idea that "Your safety" is paramount, really got my attention and assured me I was listening to someone who not only demonstrated safety but expressed it toward fellow Tech folk. After all, despite what you may learn, you've got to make it home at the end of the day. Then there was the learning part that was good troubleshooting to start and then catching your power cord issue and the correction was good stuff. To conclude, it's always good time spent watching a 'Craftsman' walk the walk. Good job.
Thanks so much!
Right on the money. Just recently had a service call on a 290 unit. Two other company's previously worked on unit. Took me a minute, replaced all they wire nuts they used with the right ones. Found low pressure switch failing. Replaced. Unit runs great. Follow up 1 week later customer stated not one issue. Gained business on the rest of their equipment. Keep up the videos. Learn alot from them. 7 months in the trade and getting stronger.
A hour video but watched all over till the recap.
Thanks buddy.
My expertise has nothing to do with refrigeration but your videos are mesmerizing. Your editorials are great. I felt as if I were right there working with you. And I did watch this entire video. Thanks!
One of my instructors( Mr. Lang) at UTI back in 1978 told us that Isobutane, Propane is a great refrigerant but never will be used because extremely flammable. He passed on decades back. I bet he is rolling in his grave after hearing about these new refrigerants. Great training video!
Listen people, take R -290 recover it and vacuum the system for 30 minutes. Add r404 to the system and thank me later. I have units running that I fixed and did this method and it works.
We have used hydrocarbon refrigerants in the UK for over 20 years and I've never heard of anyone getting hurt or starting fires when servicing them. If you don't like brazing flammable refrigerants then consider Vulcan lokring fittings which are approved for this use and eliminates the risk of fires and having to get hot works permits. I agree with the use of oem parts though as they need to be atex rated. Great video mate.
A tech was killed about 10 to 12 years ago through incorrect procedures on an industrial refrigeration system using HC refrigerants, the resulting fire caused serious damage to the business. This happened in the UK.
@@cambridgemart2075 , I didn't hear of that one, must of missed it. I think as long as people get proper training then the risk is very low. I'm glad it's separate from the F gas regs as it has its set of risks.
@@cambridgemart2075 An idiot was killed when he turned on his gas BBQ with the lid down and hit the igniter. The explosion propelled the lid into his head. You can't fix stupid.
@@solexxx8588 Very true, but nature does try very hard!
Colin, i remember reading your comment here awhile back. I just asked this question on the video comments but thought id also reply to your comment to maybe get your opinion.
What would happen if you had a compressor blow out an electrical terminal on an R290 system? Would you have a huge flamethrower?
Thanks for the tip on snapping the 1/4” copper vs. cutting all the way through! That’s a great pointer
Thank you for the second detailed video on r290. We lost some refrigerant there towards the end, and I lost a lot of sleep.
Just watched the whole video lol Chris does everything textbook style doesnt miss a beat.
I try my best but I'm not perfect!
i do oem on air recycling units for a scandinavian manufacturer and we had a machine that tripped the breaker every time they turned it on until it gave the fault code LP (low pressure), and when that happens it switches to using an immersion heater as these units are used for heating the house. Anyway we get there and the machine has 0 pressure and the compressor has a short so we disassemble the entire thing and find that the compressor wiring has rubbed against the hotgas (high pressure) line until it shorted against the copper and burned a hole through the line releasing the r290. remember these units are often placed in like laundry rooms and such, very centrally located in the houses. imagine tripping the breaker on and a flamethrower just starts flaming away in the middle of your house...
sorry for bad english but i think yall get the point, r290 can be scary stuff
Meanwhile, in many rural settings, we use propane for cooking and heating.
R290 leak is safer than a leak in some systems if it's in a small space even though it is flammable because of the poisonous (de-oxygenating) nature of them killing people in their sleep
I remember having a discussion once about the types of refrigerant to be used in cars to replace R-134a. Flammable refrigerants like R-290 and R-600a came up, but were quickly dismissed due to the fire risk in the event of a crash.
AbyssalReClass and yet they started replacing gasoline with propane or hydrogen anyway....... so why not use the R290 in the propane powered vehicles??
@@jojomorgan8556 Because LP/Hydrogen would be stored in a hardened tank in the rear of the vehicle, while the condenser for a car's air conditioning is up front, just in front of the radiator where it can take advantage of cool air from outside.
I don’t mind what people technicians Comments about you you are doing a amazing job ..To teach us your skills...And I really appreciate Your time ...I learned a lot from this video...And we have to understand that you are working for a warranty you’re not working for the regular customer
Chris I gotta say thank you so much for this content. I just got certified for r290 thru my job and worked on it for the first time today repairing a leak. It was sooo nerve racking and I came to your channel for more clarification. I really appreciate it and you don't know how much confidence your videos build in other service techs! Thanks again!
have done my fgas and passed but keep telling the company im not confident doing Daikin air source vac and pressure testing etc. watching your videos is helping me massively
Pisses me off when the manufacturer knows the parts they send out need other adapters (drier fittings).
I wish you had shown in your video what you used to connect the wiring for the low pressure control, some of these guys were probably wondering why not use wire nuts and then you didn't show the proper connectors.
Great video brother 👍👍👍
This seems to be some low quality import fridge... who the heck measures stuff in grams anyway.
@@castirondude the whole sane world measures in grams.
@@casemodder89 It's good for weighing cocaine, not much else.
@@castirondude because ? Nobody could survive an sqare yard of inch pound of frankenstein degree amount of coke ?
Considering that before propane, there was ammonia gas, this is a bit of a step up in safety.
Dont forget sulfur dioxide
Ammonia, best refrigerant
@@Valairable 👍 👍 👍
They still use ammonia as coolant on the ISS to distribute the heat from the "front" to the "back", but they have solid titanium connectors for each module that cost 30k$ each.
Ammonia isn't flammable and has a very distinct odor at very low concentrations. Not so much with Non-Odorized Propane. I've worked with ammonia, sulfur dioxide, propane and even lithium bromide as refrigerants. I'll take R-12 any day of the week over any of them.
Loved this repair, i work on R600a on a weekly basis, your safety procedures are spot on, thanks for the info.
I live in California and as a consumer the bureaucrats added $10 to every 12 oz can of refrigerant to save the whales or something. I have 90 days to claim my refund so I can't keep cans as spares without eating the cost so I retrofitted to r-290 because it's way cheaper and compatible with PAG and mineral oils. When the question of safety arises just remember that your sitting on 15 gallons of explosive gasoline compressed to 50 psi (up to 3000psi in direct injection engines) compared to a few oz or propane at maybe 300ish psi.
Exactly my point, as well. Without good carburetion, there is little risk of a dangerous flame-out or explosion.
Very comprehensive and professional videos on working with R290 refrigerants. You provide a great service to the HVACR community.
Thanks bud, I will be going live this evening 9-2-19 @ 5:PM (pacific time) to discuss my most recent uploads and answer questions from emails, the live chat, and UA-cam comments. Come on over and check it out if you can! ua-cam.com/video/n540KJDIk6A/v-deo.html
Never worked on 290, but I'm really not digging the crimping off of the lines to put a stem on them. They should just put king valves from factory. Great video thanks
it probably to keep the idiot that just got some gauges from harbor fright away :)
Master class. Thank you so much for these videos Chris. 1 hour, 5 mins & 37 seconds for the begining to the end. 👍
Got to be the first time I’ve been on the edge of my seat watching you work on that. R290 is no laughing matter. Great work as always.
please keep sharing ur commercial refrigeration videos, very helpful! thanks
10/10 video thank you very much - HVAC guy here with minimal r-290 experience. This helped ALOT
Good safe work practices. I've played around with propane and butane when making potato cannons. It explodes quite powerfully in the right conditions.
When evacuating the refrigerant we do a triple vac, so vent to atmosphere, then vacuum , charge with ofn, then vent, vacuum, charge with ofn, then vacuum again. This forces all the refrigerant to boil off in the compressor oil under the vacuum processes, also shake the compressor when venting too. I rarely get any flame when brazing doing this method. Hope this helps mate.
I've been finding failed compressors on True R290 reach-ins left and right lately. Not sure if it's the Embraco compressors, or the R290. But they're keeping me busy. Oh and I use double pitch off tools back to back and Soap bubble before torching!
My dad says R600a is a bastard gas.
It’s the embraco. I’ve been replacing a lot as well. 😂😂😂😂
Embrace made horrible r600 compressors. We have replaced so many. The replacement sourced is the meizhi. At least I think that is the spelling.
Just found your channel. I've trained in HVAC/R years ago, but never really did the work in the field. I've been working on electrical Light Rail Vehicles for over 20 years. I wanted to say that what I like most about your channel is you show everything, and that you are willing to go the extra mile to get a job done right. Much respect to you and your continual commitment to improve. Looking forward to watching more of your videos.
Can tell you were thinking, “damn my reflexes and focus are on point” after catching that 290 canister 😂👍
Very interesting I wondered how the process would go. The possibility of creating a torch in your face part made me chuckle a bit but understandably true. I like the idea you have plans ready so you don't panic.
Good Vid Chris. a tip for ya --- if u want to circulate some nitro while welding u can just stick a tiny access tube on the end of your nitro hose and just stick it in any piece of open copper.

The pressure control cry! ah I'm too hot 😞 . Nice video🙂
Replace it with R-22 and end of story. Oil is compatible and has the same working preassures.
As he said - Warranty job. Gotta do it by the numbers! ;)
Are you for real? Putting R-22 in there? In the Netherlands we aren't allowed to use R-22 since januari first 2015. (new installations can't have R-22 since januari first 2001)
Great video! Thank you for your experience. The only thing I would add in the course of your work is filter cooling when soldering (but that's just my attitude towards soldering filters). Good luck with your work.
"this is hydrocarbon based. No odorant."
Me: oh neat, he's going to show us how this stuff gets serviced. *Lights gas torch and starts brazing.* Wait excuse me what, you can do that? How are you not on fire right now I am profoundly uncomfortable.
I have new found respect for "the Air Conditioning Guy."
Your comment is likely to cause this thread to flare up.
@@gyrgrls 🤣👍
This comment is totally 🔥.
You gotta love the new chest freezers that have R600A in 'em. You just know someone with a cigarette in their mouth is gonna chip the ice off with a knife and blow them selves up! I know...It's already happened!
@@johninmilford7719 Butane isn't really that dangerous, with that low of a charge. Before you can have an explosion, you need proper carburetion. But we have natural gas or propane piped into our homes for heating and cooking, and we think nothing of it. A butane refrigerant leak is going to dissipate fairly quickly, anyway. I believe the EPA here in the US has raised the HC charge limit to 5.5 oz, or 150 grams, whichever is greater. But, for instance, 3 oz of 290 is roughly equivalent to 8.8 oz of R22. Propane and butane are excellent refrigerants.
good old days r 12, 22, 502...... i used to manipulate heat... but refrigeration like automotive engines is getting complex... stopped counting when replacement refrigerant got to 10 products... add on to this all the electronics (which would be ok but every manufacture uses different hardware and software even as far as on different models from same manufacture} then all the engineers with solutions looking for a problem.... all this requires more tools... Kudos to you in keeping your sanity
A true expert like yourself never takes that kind of credit, but that was a beautiful job, especially showing us the safety measures taken, how long was the actual start to finish, I feel that these flammable refrigerants add a lot more time to the job, all to protect the environment
Man I enjoyed that. This is the first time I watch a video on UA-cam that long. You are the master Mister. Great professional work. What I hate about these restaurant owners and hotels etc is that they don't like paying for regular servicing to keep their fridges maintained well they only call when there is a breakdown.
The fear about R-290 is hilarious to me. People think it will just spontaneously explode. Yet these same people will smoke a cigarette standing in the fuel vapors refilling the gasoline in their vehicle. Unless oxygen and the hydrocarbon or another oxidizer are mixed right it's not going to burn. You will have to have done something REALLY wrong to get a conflaguration of R-290.
Loved every minute of it. Just got a new restaurant at my food court I maintain and it's all r290 stuff. This was great info for future reference. Thanks.
I run a propane/isobutane mix for my truck A/C because it's an older R12 system. I did it because I wanted to test the system integrity before I shot it with some R12 I keep on hand. Worked so well I never changed it out. People think I'm driving a nuclear bomb when I tell them.
ohnestly I don't know why vehicle AC isn't propane. would make my life easier (as a spanner monkey) and vehicles are so well vented a leak won't do a thing, furthermore 90%of leaks are in the engine bay. the new 1234yf costs more than gold plated cocaine.
Super Duty 455 You are running a bomb, why didn't you just charge with R134a like I have been doing for the last 20 years without a problem. If it bothers ya just add a 3oz can of poly oil with 134a.
@@nunyabusiness6746 I did retrofit with 134a - properly with a flush and vacuum. Worked okay when driving down the highway. Here's the rub:
I live in a magical place called Texas where the system can't come close to keeping up.
Tell me with a straight face that I have a higher probability of blowing up compared to a Tesla.
@@nunyabusiness6746 I'm going to bet you drive gasoline like 90% of us. I'll clue you in on a little secret; those gallons of gasoline have more energy than the hundred odd grams of propane/butane/isobutane Super Duty has in his truck AC. Oh and the relatively high vapor pressure means it'll burn like a Bic lighter, not an oxy/acetylene torch like you're thinking.
@@sivalley, but the gasoline isn't piped into the passenger compartment like it is with an air conditioner...
The only thing I noticed wasn’t even in the video. I was hoping that maybe you linked where to get the R-290 dispenser that you use from. But I’m sure when it’s time that I need one I should be able to find it. Thanks for the awesome tutorial on how you do thing’s Chris. You are an awesome teacher.
Kinda makes ya love and hate the field. Well our school district just got our first R290 cooler and it will be the last. Heheh... Outstanding video and work as always. Always something to learn. Thanks to you we can all be safer at it as well!
Kaboom?
So by the time Im done with this equipemnt (out of service) you can connect your barbecue into one of the ports and still use the gas for cooking. Genious. Good vid Man as usual.
Great job...But, one thing you should never do is to fast-cool a brazed, or soldered joint. It weakens the bond between the surface areas, and may lead to cracked joints that will eventually fail.
He literally said that when he did it
I àint a hvac tech but i still find your videos very interesting to watch.
Again, the constant professional. Thank you!!!!
I work for gas station and Convenience store all of our new 3 door freezers and beverage coolers are r290 thank you for the tips and advice i will be working on them after warranty is over
6:15 "my tip is dirty" hahaha I think most of us have that problem
I hate it when my tips dirty
I've had the hardest time finding the torch tip cleaning rods.
Braze police haha
Speak for yourself. No one likes a dirty tip, and it's not the hard to keep it clean.
By far, the best HVAC/R channel. I wish I knew this stuff as well as you...
I usually just put a piercing valve then remove once I fix refrigerant/component issue. Having to braze either way I suppose.
Same here. A pierce can be brazed over easily also.
Like consumer fridges
@@broken1965 Right, there are the factory process stubs on the OEM consumer/residential and commercial also! Just add the pierce valve, perform the service, then use a pinch-off tool on the stub and simply braze the pierce hole shut. EazyPeazy
@@johninmilford7719 piercing valves leak meaning you can't get a good vacuum with them on. I use them to check pressure and recover, then sweat in access valves to pull the vacuum and recharge then pinch the line cut the access valves off and solder the line shut.
@@mikecrocop1 Sir, apparently you are not understanding the posts. We are saying to use the pierce valve as a temporary solution then pinch and braze the pierce hole. In most cases, I have been pinching the stub, cutting the original braze off and adding a standard access fitting. If using 290/600 etc, then you can't leave it, so why add it? Just make sure you put on the pierce valve correctly and you'll get a good vacuum
We got many new small refrigerator units in supermarkets and so on with R290. No problem at all ill usually just let the r290 flush itself out and vacuum pumo before brazing. U get used to it np. even if it starts burning just blow on it^^
Seems like it would be a good idea to adapt a small backpacking stove or Bernz o matic torch to "flare" the released refrigerant for situations where you can't vent to open air.
Thank you Chris! Now I know how to fix R290 system. It’s not very many of R290 system in Iowa, but there are some for sure.
you don't use flame proof mats behind the solder joint to protect the background? plumbers here in the uk use fiberglass or carbon mats as a flame guard
Great work. I've not had the opportunity to do any system work on R290 box. That drier is TINY... Thanks for the video!
Didn't know it was an hour long till you said it was a long video,lol!!! Good content
Nathan Peterson same here! I looked at length after. Haha. Great video Chris!
I’m glad to see that I’m not the only person to get a leak from time to time!
If it was me I would leave the service ports in place but maybe add some green loctite (lowest strength) and put on the cap tight. This should prevent the cap rattling loose (already unlikely) but also prevent someone bumping the cap loose.
When I do brazing I use pieces of shim metal to cover flammable components such as cords or even plastic parts of a unit so I don't have to be super critical with holding my torch. Great video BTW
I feel like a really wet rag might be a good idea to wrap the pipe that has the gas in it while brazing
No doubt
Very well done and safe . Solenoid magnets ! Learned something new . Back in 1981 we were using 24 inch of 1/4 tube a flare nut and a 1/4 inch flare union as access with a bar pinch tool with holes in it to round the process tube after use and cover the pinch area with silfoss , You may want to try this method of sealing the process tubes , After the pinch tool is on, cut the pipe and pinch the pipe 1/4 inch down from the end using the cutter of your lineman pliers , This will create a cavity on the end of the tube to be filled with silfoss . I have had great success with that method ,no leaks .
"I'm not going to stress about that fitting" as you know his OCD is kicking his ass
Chris,a fine job...you see to detail w/o rush in order for correctness.I did this work 66 to 2002, Wish that I'd had the swell new tools back then.Gauges...just about it.I braze the joints along with you...thanks
Chris, I’m reporting you to the EPA for dumping refrigerant into the atmosphere... 🤣
I vented a R290 system to atmosphere once (as per instructions), but I felt so dirty not using a recovery cylinder, it just didn’t feel right...
404 Refrigeration lmao you must be a younger technician?
It doesn't have that much effect on the environment
Probably less harmful than two bean & cheese tacos worth of farts!
actually alot more dangerous to put a flammable gas in a big empty steel cylinder./Bomb. don't ever put r-290 into a empty recovery cylinder. very dangerous ! Just vent it in an open space. r-290 is propane gas. just like your barbecue.do you feel dirty lighting your barbecue & cooking a steak ? lol.
@@OcRefrig "actually alot more dangerous to put a flammable gas in a big empty steel cylinder."
I wonder how they get all those "dangerous" gases like propane, propylene, acetylene, hydrogen into cylinders in the first place? Oh, maybe because people with some actual knowledge know what is required for combustion to take place.
Sad what America is turning into.
You have one of the best HVAC videos top class top tech.I have been doing hvac and controls for 35 years retired today keep up the good work.
There was a fairly good R12 replacement. It was called "Hot Shot". It originally had butane in the blend, but they took it out due to liability issues. Now we have straight up propane. I watched True's videos, and they tell you to take the unit outside, if I remember right. It seems like every time government makes a new regulation, it costs the industry billions of dollars. I tend to think that this is the reason for the regulations.
They make regulations first and let the industry figure out the rest.... I will discuss this on my Livestream this evening 7/13/20 @ 5:PM (pacific time) on UA-cam, come check it out ua-cam.com/video/5scxopj_QUU/v-deo.html
Thanks for the good advice. Do you have very good teaching skills. Very good knowledge of the equipment you're working on keep showing all of us up man
I've never actually worked on one of these units, but I would've probably emptied the charge before leaving and put 100psi nitro. This way no explosions overnight and a bonus leak test.
A lot of the times i have no clue what is happening, non the less i am fascinated and entertained.
I'm pleased to see that you have a fire extinguisher handy, but it appears to be a class A extinguisher, you should have a class B extinguisher, or even ABC, but not a class A. A class A extinguisher is typically just water, and will cause flames to spread. Even CO2 would be better. Besides, with a CO2 extinguisher you can always use it to cool your beer :)
I could be wrong, but it sure looked like an A bottle.
Most Kitchens today have an ABC Extinguisher for the protection.
Thank you for the r290 videos they are very helpful. I talked to a local hvac/r equipment rep and he says r290 or whatever the Freon they will user is about to replace 410 Freon in the near future.
Don’t be scared, but be VERY respectful of r290.
It's Propane. People use it for grilling all the time. It's not scary.
That said, respect any flammable gas, whether it's in AC or a grill.
Some manufacturers want you to use a double pinch off. Another great repair.
My only question is whether there was a reason you didn’t wrap the low pressure cutout switch in a wet rag while brazing? I figured you just didn’t think of it but I didn’t want to assume if there was a specific reason.
Outstanding work though - you’re a true professional! Thanks for sharing these videos :)
Very good class, I run into Refrige that has R290 and I was confused either take out refrigerant and add R134 but I wasn’t sure what to expect so told customer I come back Monday with R209 and too it off, but since watched your video, make me think differently, I have to follow your procedure ! Thanks for good advice as well!
I love that Schrader tool man. Use it everyday
Hydrocarbon is world's no 1 gas / refrigerant for refrigerator best substitute of R-12 I used hydrocarbon from year 2004 no choking problem you can charge any weather 😁😀 means rain winter best cooling effects compare to R-134a thanks 👍👍 for your helpful information 👍👍
I never score all the way through copper tubing. Just like you i lightly score then snap. saves me from reaming.
Wow, I feel like such a rebel charging up my 1988 Mitsubishi Montero with propane since I didn't have access to R12. I know the Mercedes guys do this all the time on the old 240 and 300TD's. I no longer have the Mitsu so don't rip me a new one. Great video Chris, I'm not an HVAC tech but an IT dude, and at work, we are tied into the whole iVue Kool-Aid. I make sure all my networks are up to snuff for the techs.
Remember the good old days when we blew the dust out with r12 and just dumped it to the air..didnt need no ozone layer back then
it's even more funny when they finally admit the stuff they replaced old chemicals with is actually worse, and the ozone has been fixing itself without any help.
You betya!! R12 gave the best blow j.. especially since the stuff was $20 a jug!!
Well, y'all may use recovery systems but most of the world doesn't. I can't tell you how much refrigerant of all kinds I've bled in to atmosphere, but I can tell you how much I've recovered...none in 50 years.
A few years later canada reached 49°C for the first time.
Maybe back in the days no one felt the need of an ozone layer.
But today... think twice.
Recovering nasty stuff isn't that big of a deal.
You are truly a professional. I love your attention to details and safety

I hate working on r290 because I know it's perfectly safe but others hear propane and they freak out. When around people and unable to purge it I bring in a small recovery tank that I put in a vac and let it suck out the propane so I can bring it outside and dump it.
If you told them it's legitimate to vent it lol. You can't do that with 404,134,22,502,12,407..... Why is that 😂😂
@@tjdot8 good rule of thumb, if it has R in front of it,That also means recovery, not just refrigerate, besides, one could reuse it if you ever come across another system of same!, recycle baby!
Well I did go to delfield r290 training And was told that we can vent 290. It's like 6oz in the system and you are not required to recover.
@@tjdot8 it wasn't about the legality of venting it was they hear propane and don't want me venting something flammable into the space so I do the recovery tank trick so I can just vent it outside. People are weird I try to explain that it has about as much propane as what a few bic lighters hold in butane but some people won't let go of the fear
Still is a good practice to recover any and all refrigerant, not just for safety purposes for you the tech but Clint but also for system purposes, it doesn't not take long at all to provide thai extra care for EVERYONE involved but again if you newbie, it gives you extra refrigerant for recycling, maybe and maybe not for the next Clint depending upon situation but for yourself, still I stand by to NEVER vent any refrigerant if at also possible. It also in orrdicance with EPA law, you can simply run the refrigerant through a drawers and bottle it for later purposes, you never know when you will come a cross a junk refrigerant system which you then could use for your purposes or restore it to tell sell.. thank smart people, recovery is ALWAYS better for EVERYONE involved.
I don't work on refrigeration but this video was very informative and interesting to me thanks for the video
Would it not have been easierer to install piercing valves for a first checkup?
I have to say I enjoy watching these videos, I work residential hvac and plumbing, not so much kitchen reach in or walk ins. The educational value even in this makes me think about new ways I can perform in my area of the trade. Keep up the good work.
The company I took my epa cert . For auto and universal . Main stream engineers also has 4 or 5 at home coarses where you take an on line test . And get a small certificate that says you are familiar with it . Theres hydro carbon , indoor air quality . 410 . And a few more . Great educational courses . The universal exam is administered in a private room . But these others are at home . I took all of them . Right before I got my state certified contractors . In Florida I also went to the department of agriculture and consumers services and got my propane certification . Sales and services of lpg equipment . And small gas sales . It comes in handy when safety is crucial .
Great video appropriate the real world day to day jobs we face everyday. I have not yet experienced a R-290 system.
You might wanna try using two pinch off vice grips when doing the final braze joints. It makes me feel better at least lol
Nice Danfoss system.. I have been working for that company for 10 years. Fabrication of the TU valve you have beneath the damper.
Hello Chris, your videos are awesome!
I’m a residencial service tech and I’ve been learning a ton with your videos. I really appreciate you brother. I’m a much better tech because of guys like you. Thank you.
On a different note, is this really the refrigerant of future? As a tech I love new stuff but from a customer point of view this thing kind of sucks.
It’s seems to be lot more involved with especial parts, tools and procedures. More dangerous, more time , more waiting and I can only assume higher cost to service and/or maintain. If there are other options available, it does seem like a good idea to own a system like that just for sake of being able to vent it. What do you think.
Thanks Again.

I’m just now seeing this video, yes it was long but I enjoy learning new things although I won’t be doing this because I’ve been retired for 10 years now I’ve gained a lot of insight from you doing this R-290 unit. Very interesting thanks
Here's some news, being the last guy to touch it is the guy that gonna get the blame.

Not your UA-cam program that you have. It fascinates me a lot, in fact, it helps a lot to focus on certain strategic points of this unit. And one learns many things.
Im sure someone said this already.
TRUE has a video on r290
God bless you sir! We don't work on 290 systems just for the reasons you described.
