HELiOS Marathon
TM
H850 Portable Oxygen Unit Home Use Guide
was designed to maximize freedom of
movement. Fill the portable with liquid oxygen
from the reservoir every day to use as far from
the reservoir as desired.

Tandem Mode
—You can connect the portable
to the reservoir. See
Connecting the Portable
Oxygen Unit to the HELiOS Reservoir
, page 31.
When at home and not moving about, connect
the portable oxygen unit to your reservoir with
an oxygen supply line. When the
HELiOS
Marathon H850
portable oxygen unit is
connected to a
HELiOS
reservoir in this manner,
the reservoir supplies oxygen, rather than the
portable oxygen unit.
Caution
The oxygen supply line should only be used when the
H850 flow control knob is set to a demand mode
setting.
