[DML] Re: recharging my R-12 system with R-416A (another update on #2613)



My system has a small leak.  I'm using R134 so in the states that is 
what we can buy.  When my compressor starts cycling I know I'm low 
again.  Takes about 4 oz. to stop the cycling and I add another 8 
oz.  So as pointed out already....Your only down about 12 oz.

One place I found leaking on mine were the fill valves.  You can test 
these by just putting some soapey water on them and check for bubbles.
