My package from Fish-Street and my CO2 adaptor were sitting by the front door this morning so I assembled the CO2 rig, although I won't be using it for a while, and here's how it went.
From left to right, CO2 regulator, adaptor and CO2 cylinder.
Clear instructions for installing the adaptor.
Regulator with solenoid.
Adaptor before fitting.
Adaptor fitted.
O ring for between cylinder and adaptor is a must.
O ring in place.
Cylinder before being attached to the regulator via the adaptor.
Now when I attached the cylinder to the regulator, no CO2 came out. I adjusted the adaptor to allow CO2 out and when I reattached it to the cylinder, CO2 leaked from somewhere and gave me VERY cold hands. After a good half hour looking over it, another half hour with assistance and a further hour tinkering with it, an O ring between the adaptor and the regulator was fitted and all the connections were tightened.
The set up all connected snugly, tested it in a glass of water and it goes. I will need to fill up the bottle due to the huge amount of CO2 lost during the fitting but I don't need it for at least a couple of weeks so it can wait.
