Call your local dealer, they can set you up with access. A good relationship with your local dealer is worth its weight in gold.

HVAC partners website.

It's worth it. You can install software that you download from their website; gather information in a click instead of writing it all down. You can also use software to trend the units operation to...

You order a new rotor from Carrier. I would start there.

The retrofit will be fine; you will lose some capacity, but the end results will be worth the reduction. I have done these, and they worked great.

Good explanation of how to pull a vacuum.

I detected some sarcasm jman, so I believe this to be an equivalent response; if I inferred incorrectly, please excuse my retort.

Limited info! That was one of Carriers better books. I'm sorry...

This is a link to the book you need, it is the same one that came with the unit. Page 52, it even gives you the part # to order.

This compressor is not internally field repairable; you can repair unloaders,oil solinoid, the internal check, the motor, and motor terminals. Thats about it.

You run this compressor to failure...

Call service company!!!!

Assuming that they are on the same cooling tower or cells twinned together and piped into a header of some sort, I would test water flowrates before and after the second unit is brought online....

Need to know way more than that.

Why would you want manuals from someone other than the factory? They own the rights to the manual. Go there. Anything else is copyright infringement.

TP= Test Point for testing the board.

Not for normal operations.

Have rebuilt many, nice way to jump into the low pressure chiller game. Follow the teardown instuctions and use common sense, and all should be fine. Air is this machines arch enemy, keep it tight...

It's time for you to drop back and punt this repair to someone with more experience on this unit. It sounds as if you are in over your head, and about to inflict damage upon yourself and that poor...

You are in need of a person that is competent and has worked on these before. Call Carrier or another reputable repair company. There are a lot of variables that go into the operation and processor...

I/P converter and leave the air.

Can not find that paper, maybe RCD does not like you and this is their way of letting you down easy.
I have installed 32XR panels on 22,134,12; without issue.

Carrier and other OEMs spend a lot of time and money creating and testing software for their machines. Tell the customer to stop being cheap and pay Carrier to load the software. The customer should...

That's a big girl there, you may need more than a book.

Run it to failure, and it will take a long time to fail.

There are teardown guides for all centrifugal chillers, but they are supposed to be controlled documents. If you are asking for a teardown guide and think that’s it, go get some quotes from chiller...

I wish I had a season. Year round, no rest for the weary.

Earth liberation Front, Funny.

I needed the laugh, thanks.

When a company like Carrier has given so much to the industry that we are employed. Let them call it what they want. Most of the time Carrier would work in partnership with the refrigerant...

How much faith do you put into the leak detector. Just because the purge is tripping"depending on the purge" does not mean that it is leaking. Had that happen several sites. The unit was tight as a...

You should replace them first. Sometimes the filters will clog with assembly lube that is used in compressor assembly.

When was the refrigerant filter changed last?

You will work a lot, and at all hours of the day and night. You will be running temp hoses to bldg and temp units and start up of the systems. If you are young and energetic, go for it. Old and wore...

Take away the softstop funtion and the problem will go away.

There is a certain amount of pride in keeping the old girls running. By the sound of it, you do not like working on the relics. Do what the customer wants or pass it onto another company if you are...

STP oil from Napa, it looks like honey

Look for good machine shops or industrial pump shops.
New fixes it all.
I would only do repairs on impellers in a bind.

That machine should be almost 25-30 years old. Sounds like a good time to upgrade. I love work on the oldies. Its sad that the new units will never hit that life expectancy.

Mountains out of mole hills.
I bet Carrier paid a lot of money to have that procedure written and some choose not to read it.
Below is the procedure that Carrier has on page 54 of the OIM. Happy...

That is from the book. Word for word. It is the same info in any 19xr book

It starts off round and flattens over time with heat. The O ring was correct.
Should be KK71EW128

Ramp Loading — Ramp loading controls slow down the
rate at which the compressor loads up. This control can prevent
the compressor from loading up during the short period of time
when the chiller...

It is amazing how we made it this far. Must have been dumb luck.

Seems like a lot of work. Could you not have just replaced with a new unit, or is the unit in a bad spot? Sounds like costs could be getting rather high, time = money.

I give it to you for taking...

Call Carrier. If you mess this up, you will regret it.

A wye delta starter will draw less inrush than the soft start. But the choice is yours. Not very smart to spend the money on a drive and not use it.

The number is C0129

You need to upgrade the controls to a version that has the refrigerant sensor in the cooler. If the controls are newer, then just look at a newer IOM's wiring.

New chiller controls are able to detect freeze conditions; and flow detection is going away like the low pressure dinosaur that you just put in.

If you have never done this maintenance before, you may be in over your head. You should seek the help of a qualified tech in your area and ask for assistance for the first time.

Ship work is hard, remember that mechanical rooms do not rent out to customers so they are packed into as little space as needed. The rooms are tight and hot. Your help will be from overseas, because...

It used to be every six years, however the trend today is as vibration and oil samples go south. If it is leaking, go into it and do a full stop on the unit. I could find nothing with set dates or...
