I had to replace a steel a/c line on the 1086. It is a 134 system. I attempted to recharge the system but have a question about the valves that are present on the low and high pressure schrader valve. Do I turn these valves clockwise or counter clockwise to open and do you close them after charging the system. For those concerned I have the manual for the 1086 but there is no information regarding the a/c system. I have also read the a/c forum back to 2006 but could not find an answer. I did find some interesting feedback written by Allen regarding his charging methods. Your help is greatly appreciated
