20 SEA USER'S MANUAL

NOTE: If the second stage purge was checked during the

lling procedure, it is not necessary to repeat steps 7 & 8.

5. Closely examine the pressure

indicator dial to determine whether

the needle is within the green zone,

indicating that the SEA cylinder is full.

6. If equipped with a pin indicator, the pin

should be exposed. If the pressure indicator

does not indicate that the cylinder is completely

full, repeat the lling procedure using a supply

cylinder that is lled to 3,000 PSI / 206 BAR.

7. Remove the protective retainer cover, immerse the SEA in water to

check for any signs of freeow from the second stage, or leakage from

the hose, pressure gauge, safety disc assembly, rst stage, or cylinder

neck. If leakage is found, do not attempt to use the SEA until it has re-

ceived service from a qualied technician. When complete, remove the

water from the SEA 1st & 2nd stages and reinstall the retainer cover.

8. Briey depress the purge button to ensure that sufcient airow is

provided to clear the second stage of water (N/A to PN 108382 & PN

108545).

9. Immediately after releasing the purge button, listen closely to ensure

that the second stage does not continue to allow any air ow.

10. Turn the valve handwheel clockwise until it is completely closed. In

the closed position, the red indicator ring is visible in the handwheel.

Provided that these pre-issue inspection requirements have all been met,

the SEA is now ready for use.
