19dk

I have been studying our chillers just trying to learn as much as I can, that goes for all the equipment we have but after reading (more than once) my startup, operation, and maintenance instructions for our 19dk chillers I still can not figure exactly what the purpose of these lines are. any info plus whatever else you know about carrier 19dk chillers would be appreciated.

It has been a while since I had one apart but if not mistaken the line with the square flange is the oil drain and the round flange is the ref. drain line.

square flange is oil drain. the insulated round one is motor cooling suction line. There is a check valve in the flange.

Hey the machine looks nice. Insul is tight and paint looks good. That is the "motor drain down" line. Drains refrigerant from the motor shell back to the low side pressure.

Thank you, sir. These machine have been maintained well. Started in March of '88 and still running strong. When we have out next inspection I will definitely have the tech show me around this machine so I can take some good notes.

Nice machine! Square flange actually connects the upper and lower oil sumps together.

Thanks for your help everyone.

They even piped in the auxiliary oil filters. That has to be one of the nicer plants, I've seen to have machines that old.

That is a good looken chiller room.

I agree chilbrig, Reminds of prostrate cooler tube brushing, how low can you go!

Paint covers a multitude of sins

Get ready for some severe head scratchin when you have to calculate how to set up the dreaded kingsbury thrust bearing ??

I guess you might know that from experience.
I dont know what kind of band-aid shop you work at but we take care of our equipment.

Did you get that Graham, they are the only ones that know how to use can of spray paint.

Paint is cheap and obviously Impresses people.
Nice looking plant, but first thing I noticed was, the non Manufacture recommended external oil filter installation (by the way it's not painted). See how paint covers many sins. Hahaha

If you had taken the time to view my profile before you answered you would see that I dont work for a so called "band -aid" shop , and I too know how to use a spray can .
I am a licensed millwright, refrigeration and natural/propane gas technician . I have probably seem more chiller/machine rooms than you have had hot meals .I have been doing this since I was 17 yrs old . I have also seen the gammut of machine rooms from the pristine to the downright dump and everywhere in between. Just because it looks nice dont mean sweet s&#t .All it means is someone had some spare money and wanted to impress someone with a nice paint job . Hell everyone thought the AMC Pacer was a nice car with a nice paint job. See my point ?
Take a sows ear cover it with silk , it looks nice on the outside , but underneath its still a sows ear .
Personally I would not want to work on those chillers for fear of getting them dirty , are there hospital over booties and white gloves for the techs to work on them ?? Do the techs have to put on white spray booth suits and wear masks for fear of contaminating them . !!

He could have doubled the value of the machines if he had painted them executive beige.

A co-worker and myself just finished setting up a Kingbury thrust this week on a 19XR. Reading the tools/measurements correctly is way more difficult than the actual math that is used.

This thread has gotten way to confusing.

Wow!!! I'm glad he didn't challenge the size or function of your pee-pee.......
We might have got an accounting of every sports car you have ever driven or stood beside.........lol


Good on you for asking questions and keeping it wiped down . makes sudden changes in apearance like oil easy to spot...
