SUPERMARKET RACK OIL CHANGE!!

Supermarket Rack oil change. This is for educational purposes only.

[@garypoplin4599]

29:21 - Yeah, when one of the two guys is not standing there holding a camera! Love the step-by-step videos. Very informative! It takes all the mystery out of something I’ve never done before. Builds confidence even before I get started on my first oil change! Keep ‘em coming!

[@john198292]

Thanks, good video! One thing to mention, it's good to pump some oil into the separator before starting the compressors. The float can bang around and get damaged if running the compressors without oil under the float. If you look in the ac&r separator manual it states this is important. I've only seen that cause a failure one time, but it can happen. Thanks for recording this, I always learn things from someone else's methods!

[@gr82becool]

Thanks for that information on the separator float. I will do that 👍

[@adammiller2246]

You are 100% correct

[@tram5724]

@@gr82becool I thought of 2 things as you dropped the separator plate. 1, hussmans only good product, the turboshed separator and 2, the office calling, " gotta move you"

Thanks, this is a good supplement to other instruction vids. These racks are very "valve complicated". When it comes to The Valves -- liquid, vapor, oil, whatever -- there's always a big glossing over of what's going on, e.g. "we're going to isolate XYZ by shutting off the A B C valves...." Problem: the rookie is totally bewildered by that. If he can follow, and knows That Much about rack systems, he doesn't need to watch this video. Solution: multiple "cuts" to a diagram that shows the lines being valved -- opened, closed, isolated, whatever. Onward and... Thanks and regards.

[@jrh86]

Excellent tutorial procedure and commentary 👍👍👍

[@alexanderboyd2280]

Can’t thank you enough for this video. Imma resi tech getting ready to bounce to commercial. This is a huge help

[@vadimkochkin9095]

Thanks for thorough and detailed video . Airconditioning engineer myself but very useful to know how to replace oil in a fridge pack as want to do fridge more.😁

[@JaimeMartinez-uq5we]

Great video. We appreciate all the info for a new tech like myself. Thank you

[@derrickenbuenosaires]

That's some quality work right there my friend. Practical and efficient. If I posted a vid like that I'd have everyone questioning why I didn't purge the lines with 141B lol people are crazy. Good to see you in action still. Hope all is well.

[@refrigerationconfidential4376]

Good video man keep up the great work. My favorite line “that’s just a liiiiittle bit of flood back” 😆 My guess is you have some iced up cases or someone opened some valves when the rack was low on gas.

[@gr82becool]

I see you caught that😂

[@eriknunez8757]

This makes me excited to do my first oil change on a rack system.. way better than working on package units

[@gr82becool]

You will like this trade better, of course my personal opinion. Hope this video will help 👍

[@Mgear1217]

Thank you for making this video. Appreciate it so much.

[@palamidi13]

A video worth watching, like a seminar!!!We thank you!

[@rookierefrigeration4357]

WELCOME BACK OG!!!! Nice to see u doing the thing still. Great video bro.

[@gr82becool]

Thanks 👍

[@adammiller2246]

Looks like we change oil the same way. This is the best way that keeps the rack running, making the shut down time short as possible. I carry spare float plates in my truck for two reasons. 1. When I changing oil on the rack, we shut down the rack to clean the float plate. I brought a new one and spare gaskets a long time ago. ( I have 3 most common float plates ) so when I shut down the rack, and remove the float plate, I just swap it out with the spare in my truck. Gets rack running in about 15 min. I then inspect the used plate and clean it or buy a new one if the float is damaged. 2. Here is that 2 am call again. If I am on a job where the float plate needs to be changed, or cleaned, again I just swap it and inspect/ clean float plate for the next oil event. I am sure you know what an aggravating job it is to remove the old gasket on an old Temprite 506 or 507 float plate. Always add oil to oil sep to keep the float from getting damaged. I am glad to see you also clean the sight glasses on the oil regulators and compressors. Looks like an old Tyler rack. I have worked for a contractor that services the major supermarkets in Westchester, Putnam, Dutchess counties in New York and also in the rat hole they call the city. Very well done video, you are truly a good mechanic. You work neatly and have good experience. I would hire you in a New York minute! Be safe

[@gr82becool]

I too use to carry a spare bottom plate. Until the one I had didn’t fit. So quickly started to clean up the old one to reuse. So I just stopped carrying one. Or I would need for each type, we don’t have that kind of room in our truck. And thanks for the Kind words

[@jeffreykubiak5126]

SuperMarket Guys know the trade! Thanks for showing very detailed awesome! Always learning since 1987 I know guys work some hours! HVAC tech here! Be safe out there! Happy Holidays!😎 Stay Cool!

[@gr82becool]

Thanks for watching, stay safe

[@Artisan.HVACR1]

You're back! It's been awhile since I've seen a video from you. Good to see you back.

[@gr82becool]

Thanks appreciate it 👍

[@austinhiggins6799]

so glad to see you making videos still. love em! hope youre able to keep making content. my wife thinks its hilarious i watch videos of work when im not at work xD

[@gr82becool]

It seems like we are always working 😂

[@pauljbrooks3]

My wife too is totally dumbfounded by how much work videos I watch haha

[@adammiller2246]

Well, refrigeration is a big part of your life. It helps you to be able to have a home, family, eat etc. It is a good thing that you watch the vids. You can learn what to do or not to do. Experience is the major difference between a good mechanic and a grease monkey parts changer.

[@carloscervantes618]

Great video glad your back!! 💯 Would like to see video on flood backs that would be great knowledge

[@miketomlinsonflooring3725]

Great Video!! Learned a lot!! Looking forward to your next one friend!!!

[@petervasilev7924]

Another great video! I found your channel when i started working on parallel racks and i learned a lot. Today actually i had bunker case down due to breaker down, i remember your video about short on frame heater-and guess what, my issue was the same! Unfortunately i couldn't find the size for that brass fitting you installed, for crankcase pressure. What size is that? I tried the one i installed on Carlyle, but i think Copeland is different.

[@gr82becool]

What video are you talking about with the brass fitting ? remind me.

[@petervasilev7924]

This one. On the first compressor. The plug you replace with brass fitting, on some copeland docs is used for oil removal or filling. But there's no info what size is the threat

[@gr82becool]

I believe that is a 1” deep socket

[@mth2068]

great video but did you break apart the other two compressors and clean the screens to?

[@gr82becool]

Yes we went back the next day to clean all filters

[@FallenAEbay]

@RefrigerationTech What Sockets and sizes please? I heard the 1" but the 2nd one? 1" 3? 3/4 - 3/8 - 3/16?

[@gr82becool]

I believe it’s 3/4

[@hg2.]

Min 3:00 Need diagram to show - what's pushing the oil out the yellow hose, - where the yellow hose is connected in the refrigeration cycle, - where the oil is coming from (crank case?).

[@hg2.]

Thank you for making. Some places are confusing. A diagram of the pipes would be helpful here. If a rerun of this could be made that had segways to the diagram when valves are being turned it would be great.

[@johnwalker890]

Serious maintenance work, skills and know how.

[@gr82becool]

Thanks

[@robertklein2349]

Thank you, just wondering what the spray is that he’s using?

[@gr82becool]

I’ll have to look at the video again

[@gr82becool]

He was using a degreaser to clean the screens

[@garypoplin4599]

11:05 - That oil shut off valve will need to be remounted to the rack. Did you see that mounting bolt pop out as he was pulling on the oil line? 28:58 - That oil line valve mounting bolt is still there laying loose.

[@jordanhorvath1440]

Great video. Nice trick on pumping the high side to suction. Did you put a vac on after the separator? Or did you purge it somehow? Keep up with the videos, awesome job.

[@hectortorres542]

Do it a little different to it. This is one way of doing it.Personal personally, I do not run the compressor To remove oil Cracking Suction line With about 2PSI pushes out all the oil in the compressor. But a very good video to show

[@jacobh4059]

hey man im glad i found ur videos! im just over a year into market myself and some of these tips have helped already. have u thouhgt about doing a video or two on what bags u why u run certain tools in certain bags. i find myself overloading my veto small backpack and sometimes swapping a 5411 just doesnt need that much back up lol. thanks! keep up the good work!

[@gr82becool]

Thanks, for watching. I only use two bags. Veto Back pack and MB2.

Did you have the inlet and outlet of the reservoir closed the whole time?

[@pauljbrooks3]

Welcome back!

[@rosskious7084]

What was you spraying the Sentronic sensor and oil screen with?

[@DisgustedGenXr]

Cleaner degreaser. Reducer. Virginia 10 , brake kleen etc

[@gr82becool]

A degreaser

[@JuanTodoli]

Great video 👍

[@johnwalker890]

Thanks.

[@brucecrutchfield3473]

Have to get up for work early and there’s a new video. Guess it’s gonna be a long day 😆

[@albertobartolome1882]

How many times should this Be done or is it time life maintenance routine

[@gr82becool]

It all depends on the valve. But this usually will take years for this to happen. In my 19 years of doing this I only had to do it 5 times. But this is a really old store

[@850EstatesEnterprise-n6q]

Did you make a video to address that flood back?

[@MKMMECHANICAL]

Keep posting them videos man !!!!

[@je9893]

Different than we do oil changes but this video teaches a good way to do it, great job 👍

[@SupermarketRefrigeration]

How do you do it?

[@christiansommer914]

One fine job😎

[@Bluecollarrebel]

Nice👍

[@engeclimarefrigeracao3644]

I was in doubt, because there was no vacuum? in this case it is not necessary? why? Good job. .".

[@snpdg1]

You purge it with the low side gas. Or the best is vacuum yes

[@gr82becool]

Right 👍

[@sdrgaming665]

Depends on the country, in the UK we are not allowed to purge..

[@maheradous9257]

Good job

[@hg2.]

Min 6:00 Can you let all the oil drain out that big hole?

[@micahjamestt]

You can... but using the compressor oil pump is less messy

[@DisgustedGenXr]

Didn’t notice a vacuum/purge on the separator🤔

[@sdrgaming665]

Exactly my thought as well 👀

[@D_Nice981]

👍

[@ryanellinger103]

What sizes were those sockets for the sensor and the nut for the screen in the bottom of the compressor?

1” deep socket

Do you ever have a customer say "hey, why are you making a tv video ON MY TIME??" I wonder how many tech's in the field are wasting company time by making videos to be youtube stars on the company and customer's dime. I have been in HVAC for over 50 years and it seems like every Tom Dick and Harry wants to have their own tv show while they should be WORKING. If I ever have anyone working on anything on my property making a video about it, they either stop or leave now. It could easily add an hour to an hour job. I know some guys will say "hey I'm talking while I'm working", maybe, but your concentration is not 100% on your game and HVACR is dangerous, one of the most dangerous careers in the world, OSHA investigates many injuries and deaths a year and almost all are due to lack of training and/or lack of paying attention. I wonder if any large HVACR companies have rules about it, like text and driving you're fired, tv show while working you're also fired?

[@gr82becool]

Nope not here, sorry that happened to you.
