Well i didnt get to go on my road trip to fix our
troublesome freezer some miles away today. Instead they gave me a selfcontained reachin freezer much closer to home to retrofit to 404-a from r-5o2. Ill spare you the boring details just to say that original charge was 22 Oz 502. I charged in 20 Oz to start. after 1 hour pulldown, measured -10 degrees farienhiet in box and our superheat was 8 degrees.
some say this is a little high but i couldnt bare to add any more liqid, it pulled down real nice. CAPTUBE SYSTEM
by the way. any similar experiences?
