Re: [APD] proper sequence of turning on CO2 system

["Philippe Lemaire" <ph_lemaire at gmail.com>]

Hello,

the tank pressure is about 50 bars
after the regulator 2 bars, no flow regulation per se...

I heard not to go lower to "help" the needle valve working !

Needle valve fidling is tedious but bubble rate is stable afterwards.
