Notes:
1. Do not try to overfill the H850 Portable. Once
you hear the change in the sound of venting gas
and see the cloud of white vapor, the H850
Portable is full. Continuing the fill process will
not put any more oxygen in the H850 Portable.
Overfilling may cause drops of liquid oxygen to
spray from the bottom of the H850 Portable.
2. After each fill, do not try to refill the H850
Portable again for at least 30 minutes. This will
prevent the possibility of the H850 Portable
wasting oxygen and prevent the vent valve from
potentially freezing.
3. The number of times that you have to fill up or
top off your H850 Portable depends on which
setting is prescribed by your doctor and the
frequency of your breath rate. On average, a
setting of 2 in demand mode lasts about 18 hours.
