well , when I arrived today the chiller had been re assembled and once again it leaked when water was pumped into the product It looks like it is leaking at the bottom of the chiller .

We tried to tighten the studs a bit more but the leak did'nt even slow the leak down

I put a vacuum pump on the oil tank and pulled the isolated part of the unit to 10 inches. it held that 10 inches for about 1/2 hour and before I left I started it again so it will have another 6 hrs to run
