During Use
WARNING
Always keep the portable oxygen unit in one of the
following positions: upright, flat on its back or
angled at a position in between the two. Do not
place the unit on its face. Doing so could cause the
device to malfunction and release liquid oxygen.
Such leaks increase the risk of frostbite and shorten
the time you can be away from the reservoir.
The portable oxygen unit design allows it to
operate in a variety of positions. Always keep the
portable oxygen unit in one of these positions or
liquid oxygen may escape.
1. Sitting upright
2. Lying flat on its back, but not on its face
3. Angled, anywhere in between upright and flat
on its back.
