    Oil trap or double riser.

    Depends on the system. I had systems where the liquid is so "dry", we need to inject oil in the liquid line to let solenoids and electronic expansion valves operating freely. On screw systems

    3/8" oil line on solenoid valve, 3 seconds on, 20 minutes off.
    I am not always right, but I'm never wrong!

    Common guys! Chill out.

    No sense for humor, or simple nerds?

    Not if you drain all the oil out first.
