Maintenance
Clean the fill connectors on both the stationary
and portable units with a clean, dry, lint-free cloth
between each fill to prevent freezing and possible
equipment failure.
There are no user-serviceable parts in the 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
The Reservoir makes a
hissing sound.
The Reservoir flow stops
during use.
The Portable does not fill.
The Portable vent valve
does not close properly
at the end of the filling
process.
The Portable does not
disengage easily from the
Reservoir after filling.
Liquid is spraying from the
top of the reservoir.
Frost and ice buildup and
or condensation.
Solution
• 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
• 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.
• Verify that there is oxygen in the Reservoir.
• Ensure that the Portable and Reservoir fill connectors are fully engaged
throughout 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 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.
• Contact Oxygen Provider
• Open doors and windows.
• Leave the area immediately.
• 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.

nance that my be required per the technical manual
