hi all, i have a blast chiller with some water in the sytem, i have done the normall stuff, decant the gas, change drier 3 times vacumed over night 3 times, and have broken each vac with nitrogen, i now have it on a new drier and expansion valve and on another vac overnight tonight, so when i come in 2morrow i will weigh in fresh refrigerant and run it up, question is if this doesnt work should i give up or does anyone have any tips on how to rid the system of water / moisture?
