NOTICE:
Just put in a CA storage refrigeration system. Pulled the cap off the refrigerant line, prepared for brazing. Looked inside the tubing and its plugged solid.
Found the factor put TWO plugs in the end! The other was shoved inside the tubing.
So, is this a 'one time' incident or is this a potential major problem of Cero (spelling) having a machine breakdown.
This could have really caused us major problems. Be careful all those who are piping to check if you have a clear pipe.
