HVAC REFRIGERATION: Walk In Cooler at 46

[@sknight0391]

I"m spoiled by the 👀glass on the Y.J. Titans . My favorite manifolds.

[@AlexGarcia-vv4ux]

Definitely going to start purging my gauges that way now makes sense, but I think majority of us are just use to or taught to purge the hose instead of our manifolds .

[@OcRefrig]

Thats how non condensibles get in the system. Moist morning & guages sit open in the truck overnight with water droplets inside brass manifold. 1st morning job , needs really good purge.

[@AlexGarcia-vv4ux]

OcRefrigeration , Hvac & Electrical Video's. Thank you for sharing knowledge and great advice appreciate it 💪

[@OcRefrig]

Thanks For the Credit on the vid ! 😉👍 Good vid Rook. Get yourself a Fieldpiece 4 valve manifold and purge everything out the vac. Port. U get a really easy purge that way. Much better / faster purge too. Like # 313.

[@royamberg9177]

If in doubt look at txv element to see what that's takes for refrigerant

[@OcRefrig]

Yep , Ftw. 👍

[@smod1994]

Great job! Unfortunately were im located in buffalo NY many "techs" would have just shot 404 in and called it a day. It pays to verify and reverify.

[@rookierefrigeration4357]

HVAC MaN yes sir.

[@SombraLocs]

Great video man! I don't work on too many walk ins, but all the WIC I've worked on have been R-22 and all WIF have been 404a. I shouldn't get too comfortable with my rule of thumb.

[@VentShop]

Always gotta double check things. It's good you caught it though and not afraid to say you make mistakes, honestly making mistakes is how we learn. Most of what I do is computer stuff but I still have to double check things so I don't screw it up. Trying to put a Point of Sale system together so I can make a few bucks on the side, bought parts and looked at a board today and was planning to toss 4 sticks of ram in it. Didn't double check and system only supports 2 sticks... Derp move but was able to swap a few things and will just stick the 4 sticks in a different system and make it work. I always try to write stuff down on the inside of a case as soon as I open them up so I can do a quick look and not think about it.

That is the most organized service van I have ever seen. You can actually see the floor. That's enough to get a Subscribed/Bell

[@chrisscinto889]

I purge my hoses starting from the can. Crack open then can, leave it up right, purge gas through suction hose. Flip the can upside down, purge liquid out of the high side hose. This way you know your fully "primed". Guys out there like to over complicate their purging methods. Again, if you can fill a water balloon, you can purge a set of refrigeration hoses/ manifolds

[@pralaypatel7110]

Nice video. Good catch on that freon!

[@andrewedis9907]

I had "The virus of unspecified origin" back when this was recorded. It nearly killed me but im still here...........which is nice 😊

[@articairrefrigeration9142]

Jim pettinato puts temp. Probe on cap type entering the evaporator and out going suction line for superheat when there is no suction port

[@rookierefrigeration4357]

I thought about that but after I was done. Lol. I’ll try it next time.

[@sherwinalvarez7365]

Rip Jim

[@mikestevenson1819]

Sherwin Alvarez Did he pass away

[@analogmoz]

Nor-Cal Dave said he talked to him this Spring of 2020. Jim P is still working but does not contribute to the KZbin pool of HVAC/R videos.

[@throttlebottle5906]

@@analogmoz I'm pretty sure he's happily retired and enjoying life (I believe he's around age 70 now). NO, I don't know him, but I do live in Ohio, 100+ miles away from his area and I think I was on some jobsites with him long ago(realtor/rental crapholes)

[@FlyEaglesFly19111]

I like the yellow jacket better.. I have a set of NRP.. they are leaking after 1yr. My yellow jacket oldest ones are from 2010 and are good.

[@sound39532]

I learned something today. Get the air out of your manifold.

[@andreware7536]

Thanks for the videos...really appreciate the information ✊🏾

[@reyrodriguez1005]

I’ve never considered purging back through to the tank. Interesting.

[@jamesmooney5348]

Great catch!

[@dpwade67]

Hahahaha thought I recognized that la Quinta then boom your in Dallas bro!

[@HardKnocks101]

Still using that Stratus - better man than me....

[@SoutheastHVAC]

I work on a chain of supermarkets lol. None of my walk ins have access ports except for the ones I’ve installed. Makes me furious lol

[@throttlebottle5906]

IRL, just another port to leak and they all do it ;)

[@joshstevens9826]

If u r a rookie? We need more rookies like u in sw Indiana. We cant find even a decent rookie

[@metalhead24922492]

I have 6” NRP whips for my NRP hoses 👌🏼

[@throttlebottle5906]

nothing wrong with liquid charge, just don't slug the compressor and all it well :)

[@Ted_E_Bear]

Very informational !!

[@harrydickson4575]

👍👍👍

[@philltafolla]

If in doubt , call the supply house give them the compressor info and they will tell you what type of refrigerant(s) it’s suitable with 🤷🏻‍♂️😎. Time for new equipment 🤷🏻‍♂️. What program do you use to edit your videos ?

[@HernanAnzola]

Nice video. Appreciated! Btw, what's the difference in suction pressure between cooler and freezer? (R22 talking)

[@rookierefrigeration4357]

You generally don’t use r22 in freezer because of high compression ratios.

[@mrkeynan11]

Thanks for great video. What kind of leak detect are you using.

[@Enrique-sx7dt]

Hey man great video! Super informational. Was hoping you give show me a thing or two. How come you add 30 degrees to ambient? Is that to your current psig? First year in the field trying to absorb what I can along the way

[@gregbowman3598]

Good video brother

[@frankbradley2852]

With that style gauge set up, purging through the recovery hose would in fact purge the manifold. Then you purged high low just like you originally did and it would be fine.... am I wrong? To lol

[@engeclimarefrigeracao3644]

Wasn't it quick to use the leak detector, because the liquid display showed a lack of operation?

[@rookierefrigeration4357]

ENGECLIMA REFRIGERAÇÃO yes. I knew ending everything was running. Just would not keep temp. So lack of refrigerant was the issue

[@kgmassTTV]

How do you like those yellow jacket manifolds, ive always used JBs

[@rookierefrigeration4357]

Kyle Maskell I’ll probably never use anything else. I used to have the Hilmir 3 and 4 port and gave them to a greenhorn. I’ll keep these

[@juan251100]

I like JB and been using them for a long time. I like how the hand valve angles with JB manifold

[@SaidSuil]

Hi man, nice job, just for question, why not close the valve on the deposit, and inject the fluid after the deposit? It would be much faster and will be store on the deposit whidout you need to worry, couse gas will go to expansion valve and the compressor is safe. Nice job

[@juan251100]

What is the deposit. Do u mean the receiver?

[@SaidSuil]

@@juan251100 yes the system deposit or receiver

[@rookierefrigeration4357]

True.

[@prettycureforever7102]

Why did they put black tape instead of insulation on that suction line? I'm surprised you didn't point it out and that it works though

[@rookierefrigeration4357]

Yeah. Since it’s getting replaced this was just a gas n go. Lol. 🤷‍♂️

[@throttlebottle5906]

probably customer did it to appease health department, they cry and throw fits if there's water dripping off the lines

[@manoliskritikos3825]

How satisfied are you with this leak detector , i have an inficon in Greece seems to be the best i had all this years!

[@richardcruz2630]

Is it recommended to attach your hoses to your high and low side b4 you turn the unit on ?.and is it better to do it that way ?

[@epicone2449]

If you can yea but it’s not required. 410A runs really high pressures while running, so if you put on your gauges or off while system is on it will spray on u a little. Always use gloves.

[@richardcruz2630]

@@epicone2449 thx buddy...

[@rookierefrigeration4357]

If you use ball valves you can avoid it entirely. I will try to make a video on that

[@kwiz8848]

I think its best if you can venturi effect could pull the air from hoses right into system. I like to purge my hoses soon as i hook up to the unit

[@steveblake8766]

#213 thumbs uP

[@geminithugbaby473]

24 mineral = 22 POE = 404 ?

[@hoag556]

Just purge your yellow line

[@ronnyoo9371]

How can u tell for sure ?with out tp chart i ran into a similar situation and the tp chart was a few pounds difference between 404 and r22standing

[@rookierefrigeration4357]

Txv should be a good identifier

[@manoliskritikos3825]

Inficon tek mate

[@midnightfoxxx8231]

Instead of r22 why didn't you use bluon r22 replacement don't even have to change oil

[@AlexGarcia-vv4ux]

Still would have to recover any r-22 in the system , replace the filter drier and pull a vacuum before adding any r-22 replacement. And the evaporator is most likely going to be replaced

[@rookierefrigeration4357]

This^^^

[@geminithugbaby473]

I thought 22 tanks had a tube inside that ran to the bottom of the tank and is why they don’t need to be flipped upside down I could be wrong though. Going to do some research 🧐
