Startup Issues with Trane Chiller

- This is the sequel to the chiller vacuum and charging video. This was a very challenging chiller startup for this Trane CVHF centrifugal chiller. I had some mistakes that lead to other contractors getting involved.

Just got back home from a job that i messed up the diagnosis on. Ive been in the trade for 4 years now, and whenever i make a mistake now, i just think back to year one and two, and those long drives home in silence wondering if i made the right choice getting into HVAC. Now i can shrug it off, pick out the area where i should have done something differently, or double checked something, make those changes, and move forward. My supervisor said to me, "As long as you learn from the mistake, i dont care. It means youre a better tech now than you were yesterday." Youre working on stuff I hope i get to work on eventually. Thanks for doing this channel and showing the industrial side of it.
LOL I did industrial maintenance for 20 years before I got into Refrigeration. I thought it was going to be a breeze. It's one of the hardest jobs I've ever done. There are just so many variables and it's so easy to screw something up.
"As long as you learn from the mistake, i dont care. It means youre a better tech now than you were yesterday."
- That's how you know you have a Real Boss.
I am an OEM process chiller manufacturer at Fluid Chillers Inc. I thought my job was hard. This is on a whole nother level.
Love the humility in this. So much goes into heavy commercial. Honest mistake.
Life long learning! We often learn the most from our mistakes. These machines have so many moving parts its easy to miss something like that.
Some of the most overlooked problems are the ones where the machines are not set up properly to begin with. Apparently the load on the motor before then was not exceeding the offset in the error in the settings for the CT or else that problem would have been caught sooner.
Moral of the story is that it's never good to make assumptions that things are right to begin with. It's good to verify the instrumentation using something like a clamp on ammeter to verify what the machine is reading.
i have never worked on a chiller, I learn a lot from your videos thank you.
Great video and yes I have missed current sensor also rtaa get me on that lots loose wires lol 😂
Great learning video.
I hope you guys got that chiller running. At least you're chiller experience. I'm barly still learning.
I'm working as facility engineer.I always watched your teaching video because of our building is using trane chiller .May I know how can I learn about chiller service start from begineer level.I'm trying to become HVAC specialist.Thanks so much.
What type of refrigerant?
R-123
@@BlueCollarScumWhy not 123zd?
@@MR-backupi believe you meant R-1233ZD, and that is a possibility.
Last time i checked....none us are named Jesus Christ....so that inherently makes us flawed......and prone to mistakes from time to time....in this trade...if you haven't messed up....do you even HVAC bro...lol😂....great video as always
Ellipsis, nobody seems to know how to use them...
Nice video but the words trans and nice machine should never be used in the same sentence.
"She"? How dare you! 😢
Well if you made a mistake then I'm unsubscribing 🙅♀️
Your not the only lady in my life! Sorry you had to find out this way...

Got to go evacuation in cycles, to let trapped water to thaw out. Triple sweeps do not get all the water out. And keeping the vacuum constantly for prolonged time just keeps water frozen.
heat heat heat and more heat. especially the oil. likely impossible on systems that size, unless they have in-built dedicated heaters.
@@throttlebottle5906 Thats why I said to do it in cycles. You can’t just put heat gun under the compressor on those.
Run the water to bring heat - and vacuum in cycles.
Damn that's some good s***. What about on a 35-ton air-cooled chiller, would it help to have the crankcase heater on while evacuating?
@@aleonyohan6745" would it help to have the crankcase heater on while evacuating? "
cycle it on off; watch your temps closely.

- This Trane MIGHT have one in the oil sump.
How’s everybody else noticed who’s been in the game for last few decades?. Equipment is coming with software or firmware either from the factory, or whoever was responsible for setting it up, not correct in the last decade, then. The individuals responsible at the manufactures or selling distributor, do not retain their technical staff long enough to learn their own equipment, and be competent?
Many keep moving on to different companies without enough staying behind with long-term knowledge before they move on again to another company
Therefore, the end result us who take delivery who are responsible for setting it up, end up with time, consuming and costly delays, sometimes broken parts as a result of poor set up .
And there’s often so much wrong. It’s very easy to have oversight or get frustrated on the job and miss things, especially if you’re required to do more than one brand of equipment. .
And then everyone from the factory who built the equipment to the distributors, are always pointing the finger at somebody else blaming someone else, and nobody is responsible .
I have seen this attitude increased over the last four decades immensely.
And there’s been shift in ownership of contracting companies have even more percentage of owners who are technically incompetent and inept of the products they sell .
