Hi Firestarter, and welcome.
I understand your use of voltage regulator.
Your first question.
OK, you do not need to discard anything on a strip run.
Discarding first 50ml on a turbo spirit run is probably not needed either,but why not?, it tastes like shit.
Your suggested volumes will be safe to drink, once diluted.
You would be better to collect in smaller quantities.
Unless you dllute the collected spirit, it will "burn".
In the days before I had an Essencia filter, I found a couple of Tablespoons of activated charcoal in a litre of 40% spirit, shaken many times a day,for several days and then rested in the freezer for 24 hours before pouring off, worked pretty good.
Have you read this?

I use bread yeast for everything.
Some people are very happy with Turbos.
