Aqua Lung SEA MK User Manual page 9

1. Using a calibrated pressure gauge, check the supply cylinder to
ensure that it contains at least 2,700 PSI/ 186 BAR and less than 3,100
PSI / 214 BAR. It is very important to ensure that the SEA is filled to its
total capacity but not overfilled.
2. Remove the protector cap from the threaded nozzle of the fill adapt-
er. Inspect the nozzle to ensure the o-ring is present and seated evenly
at the base of the threads.
3. Mate the threaded nozzle of the fill adapt-
er into the open fill port, and turn clockwise
by hand until snug. DO NOT apply a wrench
or otherwise overtighten the fill adapter into
the first stage.
4. Loosen the fill adapter yoke screw as needed so that the dust cap
can be removed from the inlet fitting and the yoke can be placed over
the valve of the supply cylinder.

5. While supporting the SEA with one
hand, place the yoke of the fill adapter
over the cylinder valve to align the inlet fit-
ting flush against the valve o-ring. Tighten
the fill adapter yoke screw clockwise into
the small dimple on the backside of the
cylinder valve only until finger snug.
