Introduction
B722-20-880 Issue D
The rate of pressure rise cannot be controlled by the manual vent-valve, so if the manual vent-valve is used it must
only be opened after the EXT pump speed has fallen to 50% of full rotational speed.
If a TAV vent-valve is used, but the rate of pressure rise cannot be limited, the vent-valve must only be opened after
the speed of the EXT pump has fallen to 50% of full rotational speed.
