8 - ENG PN MN234 G | User Manual
Liberator
Humidifier Bottle and Cannula are not included
8. Adjust your breathing cannula to the proper posi-
tion to breathe comfortably.
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.
9. You should be receiving oxygen now. Check to
make sure that there are bubbles in the humidi-
fier bottle.
10. Under certain environmental conditions and
with continuous use, the Liberator may develop
an excessive amount of ice on the warming and
breathing coils within the shroud. You should
defrost the unit between liquid oxygen fills to
prevent this ice build-up.
Caution: Always turn the flow control
knob to off (0 position) when not in use,
or when the unit is empty.
To Defrost the Unit
1. Fill a Portable so that you can continue to receive
oxygen while the Liberator defrosts.
2. Set the Liberator flow control knob to 0 and
allow the unit to warm to room temperature, as
indicated by the melting of all ice from the unit.
3. Check the condensation collection bottle fre-
quently during defrosting and empty as required.
4. If the Portable runs low before the Liberator is
fully defrosted, you may refill it as needed.
