Fill Termination

When the liquid oxygen level in the inner container reaches the end of the vent tube in
the manifold (Figure 2-11), liquid oxygen is expelled through the vent circuit to
atmosphere. When this occurs, the filling operation is terminated by closing the vent
valve and disengaging the Portable from the Stationary unit.
