So I've mentioned the particle counter a few times, in reference tot he pink discharge it gets after not being run for a while. This one is particularly picky. If it hasn't been run for over a week, lines will be lost, and the discharge will be noticeable pinker. This perhaps happens after a couple days.

However, a few hours of run time and all is as good as new.

The following is a before and after picture.

The before was immediately after firing it up after 2-3 weeks. The after is about 3 hours later. I will post another later tonight, and a final one tomorrow.

Before, 06DEC13 1700

How well does the pink stay away after a week - say after turning off the tube from a 50+ hr run?

I'm thinking something more than 3 hours run time could leave it in a longer lasting state of low pressure.

I've run it for a few days straight, and that'll keep it good for a few days. Though if I got 3-4 days without running, I'll go 14 before I start it up. If that makes any sense.
