I imagine the last guy said, compressor isn't running, it's low on gas, So you need a new system and here's the bid...

plastic fantastic and chrysler doing it's usual thing. you're lucky it lasted as long as it did....

"hey where do you want the control box", ""oh I don't know put it over there up high so it doesn't get hit or smashed with anything"". 🤣🤣

Will it detect a leak on copper tubing, example: I just brazed into a unit and my gauges are detecting a leak, could this thing find it for me?

Word of advice.....you really have to set fan correctly with those microchannel evaps. They will drip water into the space if it was a vertical config. With this being horizontal, you still will get water in the evap section if not set correctly.

I have that same unit at a facility, we have changed the ECM motor twice in 9 years. You need to remove the top, get a ladder and spend a ton of money to get that motor. Worst thing Trane has done

Great video. Thank you for sharing

From all brands Trane labels and schematics are the worst, most will fade out in the first year. Nice vid by the way 👍

Nice simple little unit. Got to enjoy thise days

Wooo, those are expensive Trane 8.5 Ton Precedent Package Unit, the ones I can easily find are around $11,600 plus shipping. At that price they better last a lifetime.

Absolute trash. God speed my man.

Nice work Subcool.

Nicely done, thanks Subcool.

I'm installing a 7.5T split where I work now. Didn't know you had to have an option module just to use the strips. They didn't say anything when we got the quote. With Reliatel, all you ever had to do was cut the jumper to enable them.

Both compressor are deference 1 is big than other why ?

do the 454b regs go with commercail applications ???

Good video)

First mistake was buying a dodge. Second mistake was keeping it. Don't make a 3rd😂

Oh no!

Nice to know we have a mechanic in the family

Try crayon wax. Learned that trick from a TH-cam mechanic. Thanks for the update bud

The oil cooler on those Pentastars are notorious for failure. Usually fail around 50K. Also the water drainage is an issue on the Pro masters and Ford's Transit vans. Usually end up shorting the coils out.

You have gorgeous eyes! That was nice that your son helped and you didn't try and drive your van without oil! THAT would have been a disaster! I really like your videos. Great content and good detail! Thank you.

Props to your son....he saved the day....proud dad moment there

“Outstanding” ✅

ABB > Toshiba

That sucker was dirty....when you blew it out....i was damn....how has that drive survived this long....kudos to you. Enjoyed the video 😊

I just find things are not serviceable anymore

One of the main killers of VFDs

Great video!

Nice work Subcool, thank you for the knowledge.

Oops, commented too early. But still, a head's up: Most drives have a parameter setting that electrically reverses the motor. It allows a lazy installer to reverse rotation without swapping motor wires. It is usually disabled by default. An extensive power down, faulty memory keep alive supercap/battery, or power surge can toggle that parameter when the drive is powered back up. Another thing that causes that is static electricity, which could have happened when you blew the drive out in the truck. Early versions of some Damnfussy drives were prone to that and defaulting to full factory parameters.

Damn! Yesterday I quoted an OEM indoor blower motor on a Lennox RTU, 3 phase 460v 2hp… at cost was over $1,000. And I thought THAT was ridiculous. What kind of unit is that? Never seen one of those before.

Was it $2800 for just the sensor or both sensor and interface?

Hey have you had any trouble with the Bitzer scrolls ? We've had tons of compressor failures with them .

Curious to your thoughts on Addison RTU? I still prefer Aaon with Prism.

It's supposed to go on North side to keep it out of direct sun. Direct sun on OA sensors affects sensor accuracy. Needs to be in a shaded place at all times. I Like your solution though, easy adjustment. Commissioning should have caught that.

Nice work as always Subcool.

Awfully nice unit for a kitchen lol. Thanks for the video sc

Addison and aaon must be cousins

Retired computer person. I enjoyed watching your video. I'll be doing a search for other chiller videos. I just enjoy learning new stuff.

Nice

Keep them coming bro good job.

Seems like there's a boat load of missing water. Gotta love LARPers who just screw with settings

Great video. Thank you for sharing. Happy New Year 2025

Shouldn't there be a check valve somewhere in the line to keep all the water from draining back to the tower sump when the pump shuts down? (Or if there is one, it's failed.) The scenario I see here is, pump shuts down, water flows back to tower, tower overflows, some genius at the facility sees the over flow and adjusts the float trying to stop the overflow. Side note: I did a lot of work on BacNet for Trane. Mainly at hospitals and other medical facilities. At one facility I had to, under Trane's direction, do an initial startup of a very large RTU. The one thing that was a real pucker factor was adjusting the blower drives, with the warning that if I overspeed the supply side I could literally explode the ductwork. 😮 And at the last one I did (with water chillers) we had to literally field rewire an air handler where supply and return sides were decoupled from inline to side by side (someone screwed up on the basement plans.) That was a nighmare to fix.

Nice....always fun when people just start pushing buttons without either the knowledge or leaving a note. Does those tower(s) have a bypass? That loop was air locked pretty good.

I wonder how long before the new fan will fall off. Gotta love all the new "efficient" engineering and design.
