HELiOS 300 & 800
7. You may see vapor around the fill connection.
This is normal due to the great difference in
temperature between the liquid oxygen and the
warm surrounding air.
8. Maintain a downward force on the H300/H850
with one hand during the entire filling process
and keep the vent valve lever open with the other
hand.
9. Approximately 20-30 seconds into the fill, close
and re-open the vent valve one or more times.
This will prevent the valve from freezing open.
10. The unit is full when the hissing sound changes
in tone and a dense white vapor is seen coming
from under the shroud of the reservoir. When
this is observed, close the vent valve by raising
the vent valve lever. This will terminate the fill.
11. Hold the handle on the H300/H850 and push
the release button on the reservoir until the por-
table separates (release button varies by model
of reservoir).
12. Check the contents indicator to verify that the
unit is full.
