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.

Correct installation of the oral/nasal valve is extremely important to your safety.

WARNING

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.
