Dear Mariners: I wish to remove entirely from my 1980 Hunter 36 an older Alder Barber refrigeration system that is not working. I'm primarily a day sailor, so its not at all needed. And in any case, I suspect just buying more modern ac/dc "cooler" will be less expensive than having the old unit professionally repaired (assuming that it could be repaired). My question: Before taking the unit out, do I need to have a refrigeration technician first check to determine if it contains the environmentally restricted R-12 Freon and have it evacuated? Thanks for any tips/suggestions. Rardi
