Manual Oxygen Filling

The following information applies to the : CAL3K-A , CAL3K-U, CAL3K-F.


The oxygen bottle is connected to the filling station via a pressure reduction regulator, which reduces the bottle pressure to 30bar. The pressure can be adjusted.

Open the oxygen bottle valve and observe that the oxygen pressure indication on the filling station rises to 30 bar.

Place the vessel under the filling nozzle and lower the leaver.

Observe that the vessel pressure indication on the filling station dips and then rises slowly to 30 bars. Wait 10 seconds and then raise the leaver. The vessel is now charged and ready to be placed in the calorimeter well.
