throttle bottle i cant judge from video, it looked ok to me. You are right about quality issues these days, its shamefull what is getting on the market today!
This must be a "Big box store" unit. Stores like Costco, Target, Walmart etc. I have worked on these units many times. In the 30 years of refrigeration, I had the experience of working on small self contained units, single compressor units, multiple compressor racks, ( I worked in a new Shop Rite supermarket that had a medium temp rack with 9 compressors and about 34 circuits. ) These days they usually use loop systems. Loop systems are just a main liquid line, main suction line, and some places a main hot gas line that goes around the store and the case circuits draw off of the loops. Have worked on CO2 racks, chillers, ( 134a, 22, ammonia, ) Of course water towers, with or without inverters, Regular condensers with or without inverters, self contained cases with R290, ( propane) Air conditioning units, window, split or ductless, roof top units from 1 horse power to units you walk into to service them, Fan units that are big enough to suck you into the blower wheel, water pumps, one I had the pleasure of working on, drew 985 amps while running, heat exchangers, both steam and cooling, motors from 1/20 hp to around 200 hp, compressors that were hermetic, semi hermetic, screw, scroll, Ice machines, cube, crushed, nugget, pneumatic controls, plc controls, and I am sure there is more. That is the good point of working for a company that services office buildings and supermarkets. Supermarkets have just about everything. They give you a great range of experience. The "on call " sucks, as some Ding - a - Ling will call in a case that has one nine watt motor out at 2 am and wants you to come out in the snow, on a 12 degree night to fix the freaking thing when it can wait to the normal starting time when the whole crew is in. This is one of, if not the best trade. I made a ton of money working in this trade, started my own business which is doing very well. You do have to be a person who is willing to hustle and work long hours for sure.
The wiring diagram showed the transformer at 460 vac incoming and step down to 230 vac. The guy mentioned step down 120 vac . He is very informative. He sounds young. Great video thank you.
I don't like how the "grasslin timers" are labeled AM/PM, they should have a a solid white line from both sides of the AM and PM to each end at (12:00) position I think that would better denote it, vs. looking at the hour/minute hands alone ;)
not watched yet, but it looks more "high level industrial mechanical" vs "basic refer" ;) you need good electrical, plumbing, refrigerant, oil, mechanical, framing, roofing, metal-working skills and more! to work at high end tech levels.... notice I didn't say college/engineering... Why because they are book trained mainly and have near ZERO hands on field experience, which automatically makes the majority of them useless for the first 15 years ;) DO go to college and trade schools for the field you want to work, BUT whilst working with/for a mentor in that field.....
Well said sir! I was an apprentice for a few years before I made it to Dubai where I worked for 37 years...never looked back ! Now happily retired ! :)
Thx for vid great training still learning alot in Hvac
Sweetest control panel I've seen in a good while. Must be new.
Nothing I have ever worked on was that well labeled and organized lol good video 👍🏻
I love your walk thru and style of troubleshooting approach
Awesome video, and an excellent, detailed description of control ops. Am looking forward to Part 2!
Thank you very much for your teaching , it was very instructive, God bless
Very informative video great explanation of how the circuitry works. THANK YOU
Nice condensing unit, very clean and easy maintainable. Thanks for uploading
good today, junk tomorrow ;) just the way the world of newer "chinesium" works, it doesn't

Great Information on the basic.
This was helpful!! ~ Looking forward to more videos like this!
Thanks. You have a ton of helpful videos
Great video on the topic - cant wait for Part 2 ! Thank you for the detailed explanation :)
When are you going to make some more videos about refrigeration troubleshooting
Where’s part 2?
Rookie Refrigeration that’s where you come in
Is it a 3 phase unit that connects to a Terminal Busbar then connects to the fuses that connects to the contactors. Is it like a step down system.
What do you mean by step down.
The 3 phase power trickles down the circuit?
texture6 it can go up or down. It doesn’t matter. It does have a step down transformer.
Usually on three-phase systems a control transformer is used to step down the voltage to 120, or 24 volts single phase.
The wiring diagram showed the transformer at 460 vac incoming and step down to 230 vac. The guy mentioned step down 120 vac .
He is very informative. He sounds young. Great video thank you.
Good explanation, thanks..
Very nice... Learning from YT
Cool thanks man you know your stuff keep up the good work!!
Realy its good job
I was also a fan of UEI meters. But their support is brutal so I unfortunately changed to Fluke, still think the UEI meter itself is better than Fluke
Good work!

Thanks ! very informative ! Please make more lol.
Thank you sir ! very informative !
What school did you attend if any to get to this point?
Dylan Schmidt ati. It actually shut down awhile ago. Also my dad had his own one man hvac business. I learned a lot from him.
Great idea!
👍🏻👍🏻👍🏻
👍
Sweet dude
