3.
Open cylinder cock.
Ä
The compressed air cylinder is filled.
4.
Close the cylinder cock once the final pressure is reached.
5.
Close filling cock.
6.
Remove the compressed air cylinder.
During filling, the compressed air cylinder heats up because of the subsequent
compression in the compressed air cylinder. Allow the cylinder to cool after remov-
ing it: this causes the pressure in the compressed air cylinder to drop. The com-
pressed air cylinder can then be reconnected and filled until the relevant nominal
filling working pressure is achieved.
