checking 

•

After setting the regulator, keep it pressurized with a properly set 1

st

 

stage MC9, and carry out following final checking: 

•

Put the second stage gently under water with its mouthpiece upwards 

and its Venturi checking lever in the position Dive “+”, without letting 

water enter the mouthpiece; 

•

After about 0,08 and 1,16 in. of H

2

O,  the regulator must start letting 

air flow, until the second stage does so autonomously; 

•

Check the correct working of the Venturi flow deviator, turning the 

lever in the position “-”: the continuous flow 

must

 stop; 

•

Put the regulator completely under water with its flow deviator in the 

position pre-dive (-); 

•

Wait for about one minute, then check for any leakage, shown by 

bubbles columns (not to be misunderstood with outflow of the air 

enclosed in the 2

nd

 stage); 

•

In case of leakage, please refer to the handbook description of the 

setting phase.
