5 - WARNINGS /REMINDERS BEFORE THE DIVE
Before connecting the regulator to the cylinder, check the following:
•
Check that the O-ring on the cylinder is in place on the valve and is in perfect working condition (INT
WITH Yoke nipple CGA 850 version only). If it is damaged or missing, it should be replaced.
•
Verify that the instrumentation and accessories have been installed correctly.
OCEAN REEF first stages are available with various cylinder valve fitting connectors (according to
ISO standard): DIN: screw connection up to 300 bar INT: yoke connection up to 232 bar.
While opening the cylinder valve, the pressure gauge face must not be directed towards
the user or others, in the event and risk of a pressure gauge malfunction.
If you use quick connection hose always pressurize the Neptune III gradually by opening the
cylinder valve slowly. When opening the cylinder valve, the second stage purge button
should be slightly pressed, so that the second stage valve is open.
The octopus is usually considered as an auxiliary emergency second stage to be used by
the diver in case of need (Emergency auxiliary breathing device). The OCEAN REEF Octopus
described in this manual is intended to be used connected to OCEAN REEF first stages - Maximum
depth: 50 m / 162 feet (According to EN regulation).
If a SCUBA second stage is configured for and used by more than one diver at the same
time, then it shall not be used at depths greater than 30 meters.
Do not push down on purge button for extended periods of time in low temperatures, as this
may facilitate a second stage freeze-up.
Insert hoses into the ports and tighten using a wrench without using excessive force.
Verifying quick connection hoses before the dive is imperative. Attach and detach hoses from
male connections multiple times (before and after pressurizing) to ensure the connection system
operates smoothly. Make sure, once finally connected, that the coupling is secure by pulling on
the female part of the hose, without unlocking the quick connections. The hoses must remain
assembled on the male part firmly. Always make sure you do not get dirt, sand or other material
in the hose mechanism.
Check the COMMUNICATION port plug: it should be in place, screwed into it's fitting if you
have not installed a communication unit microphone/PTT assembly. IF you have opened and
closed this port plug, make sure youu have placed the flat gaskeet that should be on the inside
perimeter - back in place.
