1-1 Scope.
a. Type of Manual. This technical manual is for your use in operating and maintaining the Special Diver Air
Support System (SDASS). It is a combined manual containing operating and maintenance procedures to be
performed by the operator, maintenance procedures applicable to unit, intermediate direct support, and
intermediate general support maintenance. Lists of repair parts and special tools, expendable/durable supplies,
and materials are also found in this manual.
b. Extent of Coverage. This technical manual applies only to specific components of the SDASS. Included are
the following:
1) Diver Air Control Console (DACC). The DACC receives high pressure (HP) air from the DASS or the
low pressure (LP) compressors, controls the diver air supply to the volume tank, and provides depth monitoring.
2) Volume Tank Assembly (VTA). The VTA receives LP air from the DACC for supply to the divers.
3) Diver Air Storage System (DASS). The DASS provides HP air storage. The DASS consists of two
groups of four racks, each containing two 5,000 psig HP storage flasks (total of 16 flasks).
4) Chamber Reducing Station (CRS). The CRS provides air control to the recompression chamber with
desired LP air from the DASS or the LP compressors.
