7.2 Removal of components for their maintenance

NOTE
Note the factory settings.
The accessory connections on the turbopump have been preconfigured at the factory.

to malfunction or fail.

Do not mix up the control lines.

Accessory connections can be configured for operation with the DCU.

ve unit of the turbopump.
