The positions of the mode selector and the gas-ballast control define the performance characteristics of the pump.
These performance characteristics are listed fully in Tables
3
and 4.
Table 5
gives the ultimate vacuum and maximum water vapour inlet pressure for each of the six possible
combinations of control positions. The curves 0, I, and II in
