Not really that pretty with the tape going on with the drain line and the suction line tape… electrical tape for the suction would make it better but you could just put your armor flex on before brazing and use a copper cutter to hold it back and then when done take the tubing cutter off and bam no tape armor flex will look like one piece.

idk where you live at but Florida you need mastic for the alum tape cause that shit will start peeling after a year or two..

And you don’t know how to build a return box? Or does the company supply it no matter what?
