Before doing the line isolation test, you’ll pump down the system by closing both service valves at the condenser. In most cases, they should accept them and the manufacturer reps that i have spoken with have said that it is not a problem. Alloy selection the hvac/r industry uses these four common base.

This happens when the water in the lines is below 32 degrees fahrenheit. I have a question, as a subcontractor is soldering using stay brite 8 and flux better than brazing ac line sets. Although these aluminum parts are of differing thicknesses, super alloy 5 bonds the metals quickly and easily.

Begin By Heating The Tube.

The only question is in a warranty situation, will the manufacturer accept an indoor unit with the flares cut off? This is the braze most often used and will have a silver content of 5% to 15%, as you mentioned. Brazing is the technique of joining the components of copper and copper alloy inside of refrigeration units and air conditioners.
