How to fill N2 tank

*Its desirable to have 3 scuba tanks in a sequence.  This is called cascading.  This is illustrated below:



1. attach N2 tank to scuba (make sure release valve is closed)
2. watch gauge, open scuba valve
3. fill until gauge stops
4. close scuba valve
5. open release valve
** repeat steps on other tanks until desired amount is reached.  Be sure to always go the same way when filling.  Example: If your using the left tank to fill dead tanks (tanks that have no air or very little) then always use that tank as your first one in the sequence.  From there keep moving to the right.  Also make sure that everybody knows which way they have to fill their tank.  

**Make sure that someone experienced is there to make sure you are filling properly.**
