How To Use Your H850 Personal Oxygen System
To keep from wasting oxygen, you should connect the
H850 Portable to the Reservoir at least 10 hours per 24
hour period. It is important that the H850 Portable be
nearly empty so that the oxygen from the H850 Portable
comes directly from the Reservoir. This will maximize the
efficiency of the system. Connect your H850 Portable to
the Reservoir as follows:
1. Thread the oxygen supply line nut onto the
oxygen outlet

2. Connect the opposite end of the oxygen supply line to

Reservoir oxygen supply outlet as pictured below
(Figure 8). Make sure the oxygen supply line and
connection is tight. If a hissing sound is heard,
tighten until the hissing stops.

the H850 Portable at the oxygen supply connector by
pushing the supply line into the connector (Figure 9).
The connectors should snap together. If the supply
line does not easily engage into the H850 Portable,
push the silver release button on the H850 Portable
connector and try again
