Gas supply Spinning disk changed again

We have issues with the CO2 dispense system from CellVivo again. Currently an old TOKAI hit CO2 supply runs on the Evident Spin SR10 system. Turn on by the “on” button and make sure the gas supply valve is open as normally. The system is hard set to mix 5% CO2 with ambient air, check the air flow by the floating metal ball in the front indicator.
