I was just curious, the lines that go into my outdoor Carrier CAC unit there looks like 2 valves(?) with caps on them which say " turn 1/6 of a turn after making contact with gasket". My neighbors on either side of me have identical Lennox units that say " turn 1/12 of a turn after making contact with the gasket". What are these caps for and why is it critical to tighten them correctly?
