Question on NX remote bottle opener

I ordered on last week and it will be here on Tuesday. Do I have to release all the N2O from the bottle to install it (like with a blow off cap and tube)?

It shouldn't be fixed on an empty bottle, b/c u'll need to conferm that it closes the bottle fully after installatin. You use a plug on the bottle outlet in this process and when the openner is fixed you test it by openning and closing then slowlly open the plu to see if its holding.

Not necessarily. If you have your n2o system already setup, you can attach the main line to the bottle, then install it. So when you open the bottle to install the valve, you'll keep the nitrous in the lines against the solenoid.

Thanks for the help! :bow:
