Hi;

I am a student in Univercity for MS degree and I am working on CO2, I designed a cascade system with CO2 and R-404A for the test.

Do you suggest any thing to me before charge the CO2 to the system for security during the filling? Or is there any installation manual for commisioning and charrge the CO2 to sytem?

Thank in advance for your replies.
