Near Regina, Sask. | I have an older 1680 that still uses R12. It obiviously has a slow leak as I put a can in every year (I still have a few cans of actual R12). I never know if I'm putting in enough or too much. Any suggestions how I can tell. I don't have any gauges but I'm planning on purchasing some. Any info would be appreciated including working pressures etc. Thanks!
