PRESSURIZE REGULATOR

WARNING:
Before pressurizing the regulator, check the condition of the hoses connected to the
regulator.
1. If there is a submersible pressure meter connected to the regulator, make sure the meter dial
is away from you.
2. SLOWLY open the bottle valve counterclockwise to pressurize the regulator. When the valve is
fully open, close it back a quarter turn clockwise.
3. Check for no audible leaks from hoses or other accessories connected to the regulator. NEVER
DIVE with a regulator that shows signs of leakage when pressurized. If there is a leak between
the regulator and the bottle valve, verify that the regulator is properly connected, and that the
O-ring is in good condition.
CAUTION:
Never attempt to reposition the hoses once the regulator is under pressure. If they are not orien-
ted correctly, close the bottle valve, purge the regulator, and replace the hoses.
4. Check to make sure that the submersible pressure meter shows an accurate measurement
of the air pressure inside the bottle at the time of loading and is appropriate for your planned
immersion.
5. Press the purge button momentarily to make sure enough airflow is provided to expel any
dust or dirt that may have entered the second stage.
6. Inhale slowly and deeply from the regulator several times. The regulator must deliver enough
air so that it can breathe easily without noticeable resistance.
NOTE:
When properly maintained, the external diaphragm of the proteus and GULL first-stage regulator
should be slightly indented when not pressurized. When pressurized, the external diaphragm will flex slightly outwards.

DIVING WITH THE REGULATOR

4.1

USE AS OCTOPUS

If a regulator such as octopus is to be used, it is recommended to cover the nozzle to prevent the
intrusion of foreign objects into the second-stage octopus.
While underwater, the regulator can begin to flow freely. If this happens, turn the regulator so
that the nozzle points down.
