I don't have a lot of HVAC training but what I'm trying to do is turn in recovered freon from burnt out compressor, so I'm trying to consolidate everything i have into a larger tank. Basically i have a small bottle with freon in it, i want to move it to my larger bottle. So i hooked the vapor side small bottle to the blue side of my gauges, the yellow hose to the filter dryer side on the recovery machine the other side of the recovery machine hooked up to the vapor side of the large tank. The problem i was having was the smaller tank was creating frost on the bottom of the tank, so i was told to try putting the smaller tank in a 5 gal bucket of hot water and try that. It was working but the large tank was getting hot like really hot to the touch and recovery machine was also getting really hot. Is there something I'm missing or not doing correctly?
