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