10. When you first notice a change in the sound of
venting gas followed by a dense, white vapor
forming around the Reservoir cover, close the
H300-50 Portable vent valve by returning the
vent lever to the upright position.
WARNING: Do not try to overfill the H300-50
Portable. Once you hear the change in the sound of
venting gas and see the cloud of white vapor, the H300-
50 Portable is full. Continuing the fill process will not
put any more oxygen in the H300-50 Portable.
Overfilling may cause drops of liquid oxygen to spray
from the bottom of the H300-50 Portable.

AUTION
: If the vent valve fails to close and the
hissing continues, remove the H300-50 Portable by
gently rotating the Portable counterclockwise to
disengage the connector. Ensure that the Portable is
kept upright and is not tipped at all during this time.
The H300-50 Portable will stop venting in a few
minutes. Allow the H300-50 Portable to warm until
you can close the vent valve. The H300-50 Portable
may require as much as 60 minutes to restore
adequate pressure for proper oxygen flow.
Note: For shorter planned use times, you can partially fill
the H300-50 Portable by closing the vent valve
sooner than normal.
