I normally put a thermometer on the lowest spot to check if I have liquid trapped. I am glad the company owned up to theeir mistake .

Ever hear of push pull?
Wow!! Great thread. Glad all worked out! And in my opinion , 10k even tho expensive , not too bad . Now , I have to follow up w the cold pot application , it's been a while since I have done this .
Would have taken a lot fewer man hours, too. On the bright side, lessons learned this way are far less likely to be forgotten.
Agreed! It was suggested a few times before to use one and my attempts to fabricate one were unsuccessful. Since this instance I have actually used someone else's cold pot to dehydrated a flooded WSHP. Worked great.

So its certainly been awhile..... like almost 3 years! I almost forgot that I even had posted this on here for recommendations. Anyway, the machine is running great to this day. After all was said and done, the recovery company owned up to their mistake and covered all of the repair cost incurred, close to $10k. We had the entire sub-cooler re-tubed, 16 tubes total. It took the re-tubing company less than a day to pull and install new tubes into the condenser. I was blow away at how fast they had gotten it done. Then I was in for the longest evacuation/dehydration process of my career. Thinking back on it now, I remember it taking almost a month and about 30 gallons of vacuum pump oil and countless nitrogen bottles. I was able to dehydrate the machine completely and I also added a few extra dryer cores in the motor cooling line and liquid injection to remove anything else left behind when the tubes ruptured. Replaced the gas with virgin and haven't looked back. We've had this machine eddy current tested within the last year with no other signs of damage. All moisture indicators are still dry to this day. It was a good lesson for me, If you want something done correctly, do it yourself!!

He hasn't been on the forum in two years.

He had no excuse because he broke the cardinal rule of continuing to remove vapor below the freezing point. Yes i understand completely, I have personally recovered and overhauled many machines and i understand proper recovery techniques. The only reason i decided to sub out the recovery process was because our large high pressure recovery machine was being used on another job at the time. I am the service supervisor for my company so even though i wasn't the lead mechanic on the job, you can see why this whole situation would fall into my lap.
