Your machine is set up for passive operation and doesn't have the required connections for active. You will need to replace the concentric reducer at the bottom with one having a flood connection to bottom flood.Basically just went back to what I know today + dewaxing sleeve and pump assist w/recovery(which took longer than me labouring on other unit).
Still can't figure out how to run active with my machine, still can't figure out why the ball valve is valuable if no one really uses them or why late into wash/recovery I can still see LPG flowing through Sleeve out of the blue.
So strange.
And greywolf, by keeping the ball valve open does this not allow whatever fats/lipids that have coagulated in tune to end up getting back into Colomn?
If you hooked the top of the column to the tank liquid valve, you could top flood and recover the way you have it hooked up.
The ball valve goes under the injection tee, so that you can bottom flood when closed.
The columns are typically drained through a filter to catch the fats and lipids. The LPG left behind is soaked into the material and leaves everything behind when vacuumed out.
