I have recently come across a system that has a HELPMAN receiver that is quite visibly full of liquid from looking at the upper receiver sightglass when running. Were talking about 30 kgs + of gas and i wonder how this can be right.What is the purpose of this amount of standing liquid ,there is a system next to this one which has the same full receiver. I reckon i could take 10-15 kgs from each tank with no problem as long as the diptube is well below the line of liquid. Someone has left the system like this am i missing something. Thanks
