add sight glass on critically charged system
Hi.
I had to cut up a sandwich table to replace the compressor, so I added service valves and a sightglass. I also estimate that I have another 3" of 1/4" OD copper to accommodate the sightglass and enough room between the cap tube and next solder joint so I don't plug the cap tube.
So, how much extra r134a would you add to compensate for a sight glass and a few inches of tubing on the liquid line?
Thanks!
