9.1 LEAKAGE AND FUNCTION TEST
Carefully open the cylinder valve to fully open. Close the valve a quarter turn!
Check the pressure on the pressure gauge to make sure that there is the required amount of
air for the planned dive. OCEAN REEF recommends that the cylinders should be full before
every dive.
If using primary breathing valve press the purge button on the breathing valve. Check that a strong flow of
air is heard. Release the purge button.
If using an octopus breathing valve, press the purge button on the breathing valve. Check that a strong flow
of air is heard. Release the purge button. Reset the locking lever against the valve housing.
Test the entire system for leaks with the following steps. Close the cylinder valve. Wait for one minute.
Check that the needle does not fall by more than 10 bar (145 psi).
If the test has been successful - open the cylinder valve following the procedure describe above.
If leakage is greater than the specified value, the equipment must be repaired by an OCEAN
REEF certified service technician.
