Looks like you got that old bugger in decent shape. That's a great lesson in patience and working the bugs out. There are people from all walks of life who become ridiculous pennypinchers. Usually the same few.

+Randy Kocian thanks

[@ianpalmer1482]

Great video Jim. Years ago a had an account with several hundred water source heat pumps. Inevitably one of the coaxial condensers would spring a leak and water would get into the system. I had an old timer show me how a cold trap before the vacumn would not only save the oil but speed up the pull down. He used an old r-22 can with another tap brazed on. I used an old recovery bottle placed in ice. Thanks again for all the videos, I look forward to them.

[@JamesPettinato]

+Ian Palmer thanks

[@Littleton98]

Ian Palmer. I would love to know more about that. Can you post some pictures?

[@RRada-kx8ip]

Nice job Jim, patience & optimism makes an old and fired tested system run once again...When I saw water running out of the liquid line in part one I thought no way will this system live to cool again!

[@JamesPettinato]

+Rich Rada I had a customer who shut his water cooled ice machine for the winter and he didn't drain the condenser, it froze up and split, the gas leaked out and in the spring he turned the water on and it filled the refrigerant lines and the compressor, when I drained the oil out of the compressor , it looked like a gray milk shake. Three oil changes, gas changes, drier changes and vacuums, it worked. thanks

outstanding,excellent.had my druthers bout the water/heat exposure but being thorugh took care of that.reminds me when my first job at major industrial plant where house mechanics totally snafu the wiring,but I did it within cost/time.and they loved it.as for asians,here in ny they have their own clique of companies to call,so that guy really was up a creek.great job as always,stay well,Brian

[@arnaldosantini1939]

Hi Jim my name is Al Santini from Puerto Rico and I really enjoy your videos, As a matter of fact some of them I had show them to my young helpers, thank you for your knowlege and way of showing how refrigeration relly works. By the way on the video that you record it on JJ's Greenhouse wich was an installation of a slow fan and Hi humidity by mid recording you mention a call you recived by a bussines owner from N.Y. in regard to a Ice Machine that after the first day was not working. I appreciate very much that coment on Grainger and the Cheap Chinese because unfortunate here in my Island do to the competition in between the supply house they forgot about us and they are salling there products to any one that walk in to the stores. So our profession is in bad shape. you know the rest. We got to do something in that matter. Poeple and Bussines owener are bieng Cheap. Keep up the good work and thank you for sharing you professionalism. Thanks

[@stevewood5447]

Very nice Jim! Woody

[@jonhexom8310]

+Jon Hexom thanks

[@J-Colt]

Hi Jim, Have watched a few video's before I noticed your in my neck of the woods. I'm out in Elyria. I'm not a HVAC guy but in maintenance and can tell you know your stuff. Enjoying very much and thanks.

[@dav1099]

Nice job Jim, way to go on the long vacuum pull down, I used to follow a "hack" a few years ago who never used a micron gauge, he would just pull a vacuum for 30 mins and call it good. lol needless to say we had to go fix it and the customer would be so pissed to have to spend more the second time to fix it again. Never pays to be a cheapskate like you said. thanks for posting.

[@JamesPettinato]

+dav1099 thanks

[@eagletek1]

great video.your knowledge has helped me alot.

[@leslieorm4905]

its amazing how you made a silk purse out of a sows ear

[@JamesPettinato]

thanks

[@Maxim_Davidov]

Nice work Jim!

[@JamesPettinato]

+Максим Давыдов thanks, how's your winter doing, it's been exceptionally warm this winter here in Ohio, USA

[@Maxim_Davidov]

+Jim Pettinato A week or two ago, there was a lot of snow and the temperature outside is about -15, standard warm winter. Now very warm and it rains. It's very strange. Winter has gone mad.

[@JamesPettinato]

+Максим Давыдов look up "pole shift", the north pole is moving towards Russia at 40 miles per year, someone said it's effecting the jet streams

[@Maxim_Davidov]

We know about the changing positions of the poles of the planet. This fact disturbs us very little. We have many political and social problems. Our country is run by bandits. Our country may be destroyed prior to the moment when a change of poles will pose a threat to human security.

[@JamesPettinato]

+Максим Давыдов I hope all goes well for you

[@jmrhvac4542]

good video Jim a lot of information on the hook up of the system.Very nice install how hard is it to start a refrigeration business or service company. thanks again for all the videos.

[@JamesPettinato]

+james rook get a truck and have stickers printed up and go around handing them out, you'll get calls, thanks

[@romtopinstal7870]

Nice video Jim.

[@JamesPettinato]

[@marcuscash5171]

[@JamesPettinato]

+Marcus Cash once you jump into the water and start swimming you'll do good

[@mrlevelle]

Great work Jim as you can see by all your viewers

[@marvingarcia8982]

Great Job. looks like u put lots of hours in this. Job looks very good Jim. I enjoy watching the video. hey would you mind making a video on that supco solution? how you apply, how much you apply, to what applications and what exactly it does?. thanks

[@20antman]

nice video Jim! I have the same vacuum pump. I called JB in the past and asked about the oil level in the vacuum pump. they told me the level should be between the lines in the sight glass WHILE ITS RUNNING. they don't care what the level is when the vacuum pump is off. so usually on this pump when its off the oil level is near the bottom of the sight glass. Also when my oil is up above the line I noticed in my experience it wouldn't pull a deep vacuum. But while its running I drained down the oil to the correct level and my microns started to drop lower. This is what made me start to wonder what is the proper level. Is it when the pump is on or off. So I called JB. just something I thought ill mention

[@JamesPettinato]

+Anthony Reardon hvacr great input, every little bit helps, thanks

[@edwardhvacr4815]

Great job of retrofit very interesting that call you got from Chinese Restaurant everyone trying to save money must low end restaurant try to beat up bill when you do service for them. When I started in the field of refrigeration work for a small 3 man shop that did restaurant the hot side & cold side we did must high end restaurant learn a lot .

[@JamesPettinato]

+edward socha thanks

[@Pyridox]

Another good job Jim. Yeah, it's not good to diagnose over the phone. Like you said without being there in person to see the machine, and use your tools to properly diagnose.

[@JamesPettinato]

+Pete Ciallella thanks

[@ritewayguy]

I've been serving a Chinese buffef for a few years. They have been good customers and good to pay. Like you said, they like to tinker with equipment. The stuff belongs to them, so, have at it. Now they are wanting to get me to lower my prices on each job. Over the years, I have given them free service calls and even even did free checks for them to show appreciation for past business. I have rarely charged them for all my time on each job. Now they want me to cut my prices. If I let them keep negotiating me down, I'll be paying them to do their work(lol). I can't work any cheaper. I may lose this customer before its over.

[@JamesPettinato]

+ritewayguy a few years back I was servicing most of the chinese restaurants around here, all of a sudden, no calls, found out some chinese guy with an old station wagon and a big mouth showed up and they all ran to him, good, thanks

[@Littleton98]

Some times you need to fire the customer

[@Believebible]

Hey Jim after watching most of your videos it seems one of your best traits is how calm you are under so much pressure. I work in this field too, mainly A/C, I and co workers get very frustrated at times. Do you stay away from caffeine? How do you stay so calm under pressure?Thanks Jim

[@JamesPettinato]

I drink two large mugs of strong coffee every morning. how do I stay calm, I've run into most every problem many times and have confidence I'll find that light at the end of the tunnel, thanks

[@ultracooling1035]

your so right on the ice maker hapens in uk all the time great vids

[@JamesPettinato]

+Ultra Cooling thanks

[@rusovich1999]

jim i not understand the valve 10 15 y calibrate i not find this range is same to r22 404a??

[@airmechanical7163]

Do you use the Supco oil on air conditioning units?

[@JamesPettinato]

+Air Mechanical sure, it's a cleaning solution it will clean cap tubes, it's main function is to line all the metal parts and make them extra slippery, so if you have a compressor binding, drawing high amps and running very hot , it will help loosen things up.

[@meerscan9101]

correct me if im wrong, isn't 67.4 psig @ 44:16 a temp of 26.2 degrees f on PT chart for r407f?

[@JamesPettinato]

+refrigeration tech I opened the valve to get a lower TD for humidity, this increases the flow of refrigerant back to the compressor thus a higher suction pressure and head pressure, as the temperature drops in the cooler the pressures will also drop, thanks

[@meerscan9101]

+Jim Pettinato sounds good, keep up the great vids

[@tazalots]

do you try to flush out the old min oil if you can

[@JamesPettinato]

+tazalots Emerson recomends mixing some mineral oil with POE oil to help keep it from hanging up on top of the liquid refrigerant in the reciever tank, thanks

[@tazalots]

+Jim Pettinato ok thank you sir

[@danamodeo1768]

Jimmy do u use nitrogen with stay brite

[@JamesPettinato]

not really, I'll displace the air/refrigerant mixture in the system then braze , thanks

[@rubencastillo9641]

Tht much water all system must be flush out with nit. New evap fked up now might last as long as a fart maby

[@saltrue1555]

Chinese restaurant owners are so chip they don’t want to pay what is fair , i always refuse to work for people like that .

[@garysmith9772]

I would have told him can I bring my bacon and eggs to you to cook, they would throw you out. When you wrestle with pigs all you get is dirty.

[@JamesPettinato]

+gary smith I've used that analogy with them , they shrug it off, thanks

[@meerscan9101]

1st thing dont buy manitowac, hoshizacki is way better! plus its evaporator coils cubers last 10 times longer...

[@JamesPettinato]

+refrigeration tech I just have a problem sending US dollars to japan or china, they're just too agressive at grabbing our money and our quality of living goes down, I've always felt if it's spent here it gets circulated here, thanks
