I remember years ago a thread discussed this about a particular chiller. That model had a small portion of one of the bundles that still had liquid covering a few tubes even after "all" liquid had...

I thought flow through the decoupler can vary the direction due to which loop is flowing more water than the other. Although, I'm unsure if that is comparing raw GPM, or % of design GPM.

I have...

You could also use a class in reading comprehension. You took "can" to mean "does". Not so. "Can" in this context means "is able to". That is IF more moisture is added. In this discussion none has...

I've always suspected that they're often lying when they say it's broken. If they don't use it, they don't have to clean it. Or, maybe they've already cleaned it that day and they don't want to clean...

Thank you sir!

I just tried to duplicate yesterday's search that led me to that. I was unsuccessful, lol. I only spent a few minutes on it too. Yesterday, that is.

What is Jet Sweat?

Hand impact driver.

That one also popped up on that Google search.
I like the idea that, with that, you can use any length handle without having to do any measuring and any math. From a stubby to any length cheater...

This made me curious.
I suck at posting links or pics here.
Google "Durofix Torque Adapter".

I have something similar in my house. Made by Sioux Chief Manufacturing. Available in different connections. I have one with water hose connections installed at the washing machine hot water hose...

The OP was asking about a way to test all fans, without pushing contactors in. I believe that can be done the same for all, but the non-drive fans will stay on until returned the output is turned...

duplicate post

He mentions keypad functions, so since there is no keypad with the older drives, I think he is talking about the Dunfoss drives. I also think he's saying that the old way of testing the old drive...

Thank you. I remember that post, now.

Drivewizard sounds like he also a nice process to test them. At least for rotation. A signal generator would give a lot of flexibility. Such as looking for...

Manny, do you know if this also works with later units with the Danfoss drive w/keyboard?

I just reread the thread.

I have never seen an RTAC with a Danfoss drive in the electrical section, much less with a keypad. I do not know if what I remember would even apply to those.
...

My RTACs serial numbers both begin with "U07H0...", indicating they were built in August of 2007. I did the startup/commissioning on them.

I've been gone from Trane almost 14 years, and it sounds like that has changed. I have not had access to TechView since. Or KestralView. The drives I recall had no Hand switch. They were simply...

It may be as simple as moving the cursor to an "unexpected" location on the screen, while you're looking at the LLID in question. I seem to recall that on the right side of the screen there are two...

For a guy looking to retire in September, it's one more freakin' day I gotta work!!!! :censored: :gah::mad:

The OEM decides what the default setting is. Commissioning/startup tech usually leaves it at that. At least I did. And explain to the customer the value of adjusting it to less, if conditions will...

Thank you!

Tery's right.
My experience in surface ship Navy nuclear power is that the Navy has very stringent and exact rules concerning that. I would expect it to be even tighter on a submarine. Any deviation...

But is he willing to gamble that the local utility will always maintain the voltage abnormally low in the acceptable range? Right now somebody may be thinking "Oh sh!t, let me turn that up...".

Read your post again and saw you already have been in binding view. I'm thinking there is a way to toggle the device output, but like I said, it's been a while for me.

It's been several years, but you may need to go into binding view, pull up that device, and operate its output from there.

My experience with utilities is the same. But I'm not worried about winning the argument. I know how they play the game - I advise my customer to call them, the utility denies a problem, problem...

One of my earliest jobs was to help rebuild one of these. It was also when I learned NOT to sit cross-legged under there while removing the vane bellows assembly. Must have had a pint of oil fall...

I saw literature on these stating that they have "adiabatic pre-cooling" on the condenser. I suspect this means some kind of mesh or mat near the face of the condenser coils that is supplied with...

Welcome.
Not only do I not have experience on this particular chiller, or any Multistack chiller for that matter, in 25 years as a chiller tech in the field (those 25 years ended 14 years ago), I...

Very early in my career my shop circulated R113 through a severely rusted R11 machine that had filled with water. My involvement was limited. While riding with a tech, we stopped by to measure...

Do the efficiency numbers account for creating the vacuum that helps to produce the "steam"?

What do you do with 71C "steam"?

The H10 is all I have used, because it is all I have fully trusted. It was recommended to me by senior techs where I began and I never had a reason to try anything else. Although I did have to get a...

It was a new maintenance account on a few-years-old, air-cooled screw chiller (Trane RTAA). Found what I thought was wire-pulling soap in the electrical section. Cleaned it up, all other electrical...

I'll miss his talent and his support of the military.

I have seen a transducer, installed by an OEM and nowhere near any brazing or solder, leak out through the cable all the way to the control module in the electrical cabinet. And I have heard of other...

Captain Daniel V. Gallery commanded the task force that captured the U-505. He wrote a book about it. It's very interesting. He went on to write a few more books that were basically a collection of...

You are both. Doing something wrong AND misunderstanding.

US Navy, 1979-1985. Best decision I ever made, other than marriage. Navy training and experience set me up for a job/career as a chiller tech with Trane. The job with Trane resulted in a relocation...

Thank you for that link, slctech!
Another building in our complex is getting a new chiller. It is scheduled to arrive today. It is a Daikin, and it's my understanding that it has two Turbocores....

Thanks for the heads up Terry! I'm going to have to look those up.
It's been many years (30?), but I once toured the USS Drum in Mobile, Alabama. I recall it being very interesting.
What WWII sub...

Make sure coils are piped correctly. (I know this is very important with chilled water coils, entering water on the leaving air. Not so sure how important with hot water coils. I know one difference...

I have seen my infrared temperature sensor show a difference of more than 30F on a hot water pipe as I move it from the copper pipe to an iron fitting.

I find that the best use of it is to simply...

And keep an open mind. Once I found somebody had run conduit through the floor of the unit. Not only was the penetration inside the curb, but they didn't even attempt to make it waterproof.

This "out of phase" condition, is it something you've measured (if so, how?) or is it something you've assumed? I ask because I don't see how that can apply to what you're seeing regarding motor...

Pacnw, my google search did not bring up drunk driving. Makes me wonder about your search history... :whistle: :grin2: :cheers:
Just kidding with you!

Is this the capacity control module for the Classic Black control panel? The first control panel on CVHEs?

Many people who are off-grid do exactly that.

If the solar is to complement the grid, or replace it during outages, then some will have both AC and DC in their house.
