Filling The Sea With The Mrs-Iii Mobile Refill Station - Aqua Lung SEA MK User Manual

14 SEA USER'S MANUAL
7. To conserve the limited air supply of the SEA, it is strongly recom-
mended that you perform the following pre-issue inspection of the second
stage purge while the SEA is connected to the compressor fill yoke and
pressurized via the compressor fill adapter:
a. Briefly depress the purge button to ensure that sufficient airflow is
provided to clear the second stage.
b. Immediately after releasing the purge button, listen closely to en-
sure that the second stage does not continue to flow any air.
8. While holding the first stage and fill adapter secure, turn the SEA valve
handwheel clockwise until it stops and the red indicator is visible. Turn the
compressor fill valve completely closed.
9. Hold the second stage purge button depressed until air flow can no
longer be heard from the second stage and the LP hose is depressurized
(N/A to PN 108382 & PN 108545).
10. Open the pressure relief screw on the compressor fill yoke to relieve
the line pressure.
11. While holding the SEA cylinder supported, turn the yoke screw of the
compressor fill yoke counterclockwise to loosen until the compressor fill
yoke can be removed from the block of the fill adapter. Return the com-
pressor fill yoke to its storage location.
12. While holding the SEA secure, turn the fill adapter block counter-
clockwise at the fitting to loosen and remove from the first stage.
13. Thread the fill port plug back into the fill port until fingertight.
14. When charging is complete, remove and store the compressor
adapter in a clean area.

Filling the SEA with the MRS-III Mobile Refill Station

The MRS-III is a self-contained Mobile Refill Station with an onboard supply
of approved breathing air pressurized up to 4500 psi. The MRS-III is designed
to fill up to two (2) Aqua Lung SEA (Survival Egress Air) units simultane-
ously to the operating pressure of 3000 psi. The following instructions are
the same for filling one unit or two (Refer to the MRS III instruction book for
more detailed instructions).
1. Verify that both panel-mounted Fill Valves on the MRS-III are
closed (clockwise).
2. Open the Valves on the MRS-III Supply Cylinders and verify that
the SUPPLY Pressure Gauge on the panel reads between 3000 and
4500 psi.
3. Verify that the REGULATED Pressure Gauge on the MRS-III panel
reads 3000 psi.
