5. Open the handwheel to pressurize SEA.
Closely examine the dial indicator to ensure
the cylinder is filled to its maximum capacity
as marked (Fig. 12).
NOTE: SEA utilizes a "GO" / "NO-GO" system of RED and GREEN
segmented dial indicators based on usable gas volumes in accordance
with EN 4856. The "GO" GREEN ZONES are set as follows:
0.25 L 232 bar system has an indicated GREEN ZONE FROM 222 - 232 bar.
Cylinders are primarily measured in their floodable volume and secondly
by their expanded volume as follows:
Usable gas is defined as: "Volume of breathable air available to the user
while the demand regulator is operating within the specified breathing
performance". As stated in EN 4856 paragraph 3.22 usable volume of air.
6. Remove any mouthpiece covers from the second stage. Immerse SEA in water to
check for any signs of leakage coming from the first or second stages. If any leakage
is found, do not attempt to use SEA until it has received a thorough visual inspection
and functional test by a manufacturer trained service technician. Upon completion
of the immersion test, remove SEA from the water.
7. Briefly depress the purge button to ensure that sufficient airflow is provided to clear
the second stage of water. Immediately after releasing the purge button, listen closely
to ensure that the second stage does not continue to allow any airflow.
8. Close the handwheel and depressurize SEA, refill the cylinder to its maximum
capacity as marked.
Provided that these Pre-Use Inspection requirements have all been met, SEA is now
ready for use.
POST-USE INSPECTION
1. After use, close the handwheel and completely depressurize SEA. Check for signs
of damage and contamination. Report any discrepancies to maintenance personnel.
