8. Connect to air supply fill whip (Fig. 7).
9. Open the handwheel to allow the dial
indicator to register.
NOTE: SEA will fill with the handwheel in the "OFF" position (red indicator
ring visible). In this position the dial indicator will not register pressure.
This is not recommended.
This is not recommended
10. While supporting the cylinder with one hand, very slowly open the air supply
valve to begin filling (do not exceed a fill rate of 30 bar per minute). Make sure the
dial indicator shows that the cylinder is filling properly.
11. When air can no longer be heard flowing from the air supply fill whip into SEA,
completely open the air supply valve.
12. While holding the cylinder secure, close the handwheel on the air supply valve.
Close the handwheel on SEA and depressurize the system.
13. Open the bleed valve screw on the air supply fill whip to relieve the line pressure.
14. While supporting the cylinder with one hand, disconnect the air supply fill whip
from the fill adapter. Remove the fill adapter from the fill port.
15. Check that the o-ring on the fill port cap is present, not damaged and seated evenly
at the base of the cap. Thread the fill port cap back into the fill port until finger-tight.
16. Verify the cylinder has been filled to its maximum capacity as marked. This can
be seen when the dial indicator reads in the green zone.
NOTE: Always fill the cylinder as slowly as possible (do not exceed 30 bar
per minute) by turning the handwheel 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.
NOTE: These steps may vary due to the type of HP compressor.
