5. Carefully Open the valve of the large gas bottle(The valve on the Soda-Strean Cylinder closes the flow if it is opened too much. This will happen if you open the big cylinder too much / too fast. The trick is to open the big cylinder very carefully. You will hear the airflow. So to fill it successfully).

8. Opening the bleed screw to drain residue remaining gas.
