After the oil leak checks. Fill the system with a given amount of
compressed air. Use a tire air fitting at the service port, put in about 150
lb's or so. Use a spray bottle filled with soapy water, sprayed on fittings,
etc. (look for bubbles), check to see if it holds pressure, should hold
indefinitely, 24 hr test should tell the tail.
If the system holds, then vacuum system of the air, and fill with 134 a
as usual. Of course recheck for leaks with an electronic tester. The most
important test of all, the road test, ENJOY!!!!
