"and a machine right next to the one we were overhauling" what do you mean no air conditioning? Sounds like you had plenty

No air conditioning!!! The horror! Rob, you make it sound like that is unusual. I've only seen one owner with air conditioned chiller rooms. Thankfully it is a large campus with four chilled water plants. It was always a pleasure to work there.

Good stuff man! CTV Service Guide 3 in color.

For a machine like this, around two weeks to do a right proper job for the customer and to do it safely. Some are easier than others. As long as nothing crazy happened, most Carriers and Yorks can be done in about a week, I think.

That is, until they heard the sound of something inside "giving way". Yep, they completely skipped disassembling the compressor. I don't recall hearing what it was that broke.

Must have forgot to take the nuts off the torque converter. Kind of hard to pull a motor unless you do that.

When I read Rob's post requesting the mods to rename this thread, I immediately knew who he was referring to. And I laughed. Funny stuff.

So the purge discharges into the cylinder instead of the atmosphere?

I believe it just holds water/air/refrigerant/moisture/ to become a rust bucket??

Hello Rob, could you or someone else identify that "propane tank" on the side of the condenser for those of us not intimately familiar with low pressure refrigeration?

It appears to be a factory item.

(it still amazes me. the size of that suction line. to think of the volume of gas going through there. much higher than r22 for example per ton)

Thanks again for sharing~

Mods,

Could you please rename this thread "TechRob a professional HVAC tech teach you how to repair the centrifugal chiller from LaCrosse Wisconsin"

Just kidding

Those people are well-deserving of a Darwin Award. Stupidity of that magnitude is about as common as catching a glimpse of one of those comets or some other cosmic event that only appears once a century and the results are just as awe-inspiring and spectacular.
