Correct installation of the oral/nasal valve is
extremely important to your safety.
7.8.3 Oral/Nasal Replacement
1) Snap the oral/nasal over the regulator mount nut
(45).
2) Reinstall the microphone.
3) Reinstall the nose block device.
4) Ensure that the oral/nasal valve has been installed
correctly.
The oral/nasal valve must be replaced
correctly to provide gas flow in the proper
direction. The flow through the valve must
be from the interior of the helmet into the
oral nasal mask. This will allow the diver
to breathe the gas from the defogger valve
freely, yet help to reduce carbon dioxide
inside the helmet.
If the valve is not replaced properly this
could make it difficult to breathe the gas
supplied by the defogger and expose the
diver to an excess of carbon dioxide. This
could lead to exhaustion and blackout
resulting in serious injury or death.
