HELiOS
Introduction
A liquid oxygen system is designed to provide sup-
plementary oxygen as prescribed by a physician.
Your liquid oxygen system includes a HELiOS
reservoir. This user manual contains the instruc-
tions for using the HELiOS reservoir.
The Helios reservoir is intended for the administra-
tion of supplemental oxygen to the patient in the
end user’s home and can also be used in institutions
such as nursing homes or sub-acute care facilities.
The device is not intended for life support nor does
it provide any patient monitoring capabilities. It
is recommended to have an alternate source of
supplemental oxygen in the event of mechanical
failure.
The device is used by COPD patients or those
with diminished breathing capacity. The device is
prescribed to the patient. The device is sold to a
provider that is trained to operate and service the
Helios reservoir. The provider trains the user.”
Your liquid oxygen system may also contain a
portable unit to provide an ambulatory source of
oxygen for an extended period of time. Refer to the
user manual supplied with your portable unit for
information on its operation.
The HELiOS reservoir is lled with liquid oxygen
by your health care provider. It is designed to store
the liquid oxygen for the purposes of lling a por-
table unit, and breathing directly from the reservoir
for stationary use.
The HELiOS reservoir stores liquid oxygen that
can be used to ll a portable liquid oxygen tank.
HELiOS Universal reservoirs can ll any CAIRE
top ll (TF) portable with a compatible ll connec-
HELiOS Universal Reservoir shown.
Universal & Standard reservoirs are available
in 36 and 46 liter models.
tor. HELiOS Standard reservoirs can only ll the
HELiOS H300 Plus and H850 Marathon portable
units (see Standard and Universal Reservoirs sec-
tion for model identication).
The HELiOS reservoir is also designed for station-
ary use. Continuous oxygen ow from 0-10 LPM
can be taken directly from the reservoir with the
attachment of an external ow control valve.
Another method of stationary use is to connect
a HELiOS H300 or H850 portable unit to the
HELiOS reservoir using an oxygen supply line.
When the portable is connected to the reservoir in
this manner, the reservoir supplies gas oxygen to
the portable and allows you to breathe from the
portable as a conserving (demand) device without
lling it.

5. Turn the knob on the external ow control valve
until your prescribed continuous ow rate (nu-
meric in LPM) is displayed in the window and a
positive detent is felt.
NOTE: The knob should not be set higher than the
maximum flow rate prescribed by a physician.
NOTE: Out-of-specification oxygen flow will result if
the flow control knob is set between flow rates.
6. Properly position your nasal cannula and adjust
it for comfort.
NOTE: Ensure the cannula is fully inserted and secure.
During inhalation, you should hear or feel oxygen
flow to the prongs of the nasal cannula. The proper
placement and positioning of the prongs of the
nasal cannula in your nose is critical to the amount
of oxygen delivered to the respiratory system of the
end user.
7. You should be receiving oxygen now. Check
to make sure you feel oxygen ow into your
nose and that there are bubbles in the humidier
bottle (if used).
8. Turn the ow control knob to the off (0) position
when the reservoir is not in use.
9. Under certain environmental conditions with
continuous use, the HELiOS reservoir may
develop an excessive amount of ice on the coils
visible under the shroud. You should defrost the
unit between uses to minimize this ice buildup.
To de-frost the unit:
• Fill a portable unit so that you can continue to
receive oxygen while the HELiOS reservoir
defrosts
• Set the knob on the external ow control
valve to the off (0) position and allow the
unit to warm to room temperature, as indi-
cated by the melting of all ice from under the
shroud.
• Check the moisture container frequently dur-
ing defrosting and empty as required.
• The container should be emptied whenever
the water reaches the (1/1) line visible on the
outside of the container. If the water is not
emptied, moisture may spill onto your oor.
• To empty the moisture container, pull out on
the container and pour the water into a sink
for disposal.

HELiOS
User Troubleshooting
The following information is intended to help you troubleshoot and solve simple operational problems that
you may experience when using your HELIOS Reservoir.
Issue Solution
The Reservoir makes a
hissing sound.
• Hissing can occur to maintain the correct operating pressure within the Reser-
voir. It is most likely to hiss after filling or when the position of the Reservoir
is changed. Hissing can last for 30-60 minutes after filling. Furthermore,
improper filling or lower than normal operating pressure in the Reservoir will
contribute to the unit not being able to fill portables and improper flows
The Reservoir flow stops
during use.
• Ensure that the cannula is firmly attached to the Oxygen Outlet.
• Ensure that the cannula is not kinked.
• Ensure that there is oxygen in the Reservoir.
The Portable does not fill. • Verify that there is oxygen in the Reservoir.
• Ensure that the Portable and Reservoir fill connectors are fully engaged
throughout the filling process.
The Portable vent valve
does not close properly
at the end of the filling
process.
• If the vent valve fails to close and the hissing sound and oxygen vapor cloud
continue, carefully remove the Portable by depressing the release button on
the Reservoir. Venting from the bottom of the Portable will stop in a few min-
utes. Allow the unit to warm until you can close the vent valve. The Portable
may require as long as 60 minutes to restore adequate pressure for accurate
oxygen flow. If needed, use an alternate source of oxygen such as a flow
control valve attached to the Reservoir.
The Portable does not
disengage easily from the
Reservoir after filling.
• The Portable and Reservoir fill connectors may have become frozen.
• DO NOT USE FORCE OR USE WATER. Allow a few minutes for the frozen parts
to warm, then disengage the Portable when the ice has melted. To prevent
the units from freezing together, always wipe the male fill connector on the
Reservoir and the female fill connector on the Portable with a clean, dry cloth
before filling.
Liquid is spraying from the
top of the reservoir.
• Contact Oxygen Provider
• Open doors and windows.
• Leave the area immediately.
Frost and ice buildup and
or condensation.
• Some frost and condensation is normal on the warming coils
• Condensate collector is full; empty the tray.
• Ensure the Flow Control Knob is closed if not in use.
Maintenance
Clean the ll connectors on both the stationary
and portable units with a clean, dry, lint-free cloth
between each ll to prevent freezing and possible
equipment failure.
There are no user-serviceable parts in the Helios.
Your service provider is responsible for any mainte-
nance that my be required per the technical manual
of this device. Call your service provider for any
maintenance requirements.
The expected service life is a minimum of ve
years.
