6.5 Make-Up Panel<br />
11.The BPR loader regulator, regulates the pressure set on the Reprocessing Unit<br />
back pressure regulator.<br />
6.5.1 The make-up gas panel has two basic sections: the make-up gas section <strong>and</strong> the<br />
oxygen enriching section. The make-up gas section provides both gas to increase the working<br />
depth of the system <strong>and</strong> make-up for any losses either at surface or at the diver. The oxygen<br />
enriching section provides means of rapidly adding oxygen to the system at a much faster rate<br />
than the metabolic oxygen addition system. This is used when changing to a shallower depth, or<br />
when a higher oxygen content is required.<br />
Fig 4 Make-Up Panel<br />
1. O 2 supply gauge – indicates oxygen pressure available to the panel. Note: This gas<br />
comes from the O 2 regulator on the oxygen panel.<br />
2. O 2 supply valve – provides manual shut-off of oxygen to the O 2 enriching orifice.<br />
3. Vent valve- is normally open to prevent accidental addition of oxygen into the<br />
system.<br />
4. The HeO 2 supply gauge – indicates the HeO 2 pressure available to the make-up<br />
system.<br />
5. The HeO 2 supply valve – provides manual shut-off control of HeO 2 to the regulator.<br />
6. The HeO 2 regulator – is a high flow, self venting regulator which controls the makeup<br />
gas pressure available to the volume tank.<br />
