    Lineset considerations for oil return etc



    Hey guys, I just want to run this up the flag pole before doing it.

    I'm stuck between concerns about oil return, and not wanting refrigerant running down towards the compressor during the off cycle. Or maybe even oil for that matter?



    Do I want pitch on the horizontal run as I assumed, or will this tend to cause slugging on startup?

    I was always told inverted trao right at vertical drop and if off on cycles are far apart then at the very least a compressor heater would help on migration
