Filling the SEA with compressor fill adapter
NOTE: the Compressor Fill Adapter (P/n 1006-56)
is not included with SeA, and must be purchased
separately.
WARNING:
Do not attempt to fill the SEA directly from a
compressed air filling station unless you have received
the necessary training and authorization to do so. if done
incorrectly, this procedure poses certain hazards which
may cause severe injury or death.
NOTE: Part number 108382 does not have an on/
off valve; therefore, the pressure indicator gauge
and second stage are always active when the cylin-
der is pressurized.
1. Inspect the fill adapter to ensure that the o-ring is present
and seated evenly inside its groove, and the male fitting is
clean and free of any damage to its threads.
2. Mate the male fitting of the fill adapter into the high pres-
sure fill port of the first stage, and turn clockwise only by
hand until lightly snug. DO NOT apply a wrench or other-
wise overtighten the fill adapter.
3. Loosen the yoke screw of the compressor fill yoke as
needed so that the yoke can be placed over the block of the
fill adapter.
4. While supporting the SEA with one hand, place the yoke
of the compressor fill yoke over the block of the fill adapter
to align the inlet fitting flush against the valve o-ring. Tighten
the fill yoke screw clockwise into the small dimple on the
backside of the fill adapter block only until finger snug.
CAUTION:
DO NOT attempt to fill the SEA from a com-
pressor or air supply where the regulated pressure
exceeds 3,000 pSi/ 206 BaR. Doing so may weaken
and damage the safety burst plug assembly and/ or
SEa cylinder.
5. While holding the first stage and fill adapter secure, turn
the SEA valve handwheel counterclockwise until it is com-
pletely open. When the handwheel is in the open position,
the red indicator ring is not visible.
6. Ensure that the SEA is supported, then turn the compres-
sor valve very slowly until it is slightly open to fill the cylinder
with approximately 500 PSI/ 34.5 BAR. Turn the fill valve
shut and wait 45-60 seconds before proceeding to fill the
cylinder any further. Repeat this procedure to fill the cylinder
very slowly in small increments of 500 PSI/ 34.5 BAR or
less, until it is filled to exactly 3,000 PSI/ 206 BAR.
WARNING:
use safety glasses when charging with hp air.
NOTE: Always fill the SEA as slowly as possible by
turning the hand-wheel of the supply valve slowly to
control the rate of fill. Rapid filling will generate heat
and will result in an incomplete fill after the cylinder
cools. If the cylinder is warm to the touch afterward,
the fill rate was too rapid.
7. To conserve the limited air supply of the SEA, it is
strongly recommended that you perform the following pre-
flight 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 suf-
ficient airflow is provided to clear the second stage.
b. Immediately after releasing the purge button, listen
closely to ensure that the second stage does not
continue to flow any air.
8. While holding the first stage and fill adapter securely, turn
the SEA valve handwheel clockwise until it stops and the red
indicator is visible. Turn the compressor fill valve until it is
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.
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 valve can be removed from the block
of the fill valve adapter. Return the compressor fill yoke to its
storage location.
12. While holding the SEA secure, turn the fill adapter block
counterclockwise at the fitting to loosen and remove from the
first stage.
13. Thread the port plug back into the fill port until finger
tight.
