11 | FREELOX PORTABLE V4 Level – User manual
7. Preparing and starting up the FREELOX PORTABLE
7.1.Preparing the equipment
Check that the remaining oxygen level shown on the stationary
tank’s level gauge is greater than or equal to 1/4. If the level is
lower than 1/4, do not fill the FREELOX PORTABLE, in order to
avoid any problems related to the filling of the FREELOX
PORTABLE.
Before filling, insert your finger into the opening (3) and remove the
condensate collector (2) located in the lower part of the FREELOX
PORTABLE, along with the felt (1) it contains.
Rinse, wring and dry the felt (1) between each use.
Remove the protective cap (1) from the stationary tank’s connector.
Eliminate any traces of moisture on the filling connectors of the
stationary tank and the FREELOX PORTABLE using a clean, lint-
free cotton cloth (moisture leads to the formation of frost on the
connector and can cause oxygen leaks).
Set the FREELOX PORTABLE’s flow rate selector button to the 0
position.
When using the FREELOX PORTABLE, as with any oxygen therapy unit, ice will form on some of the components,
especially the heaters located inside the device. When you stop using the FREELOX PORTABLE, the condensate
formed by the melted ice is found in or flows into the collector. This phenomenon is normal and poses no risk to the
user. The FREELOX PORTABLE device can therefore be immediately reused. .

12 | FREELOX PORTABLE V4 Level – User manual
7.2. Filling the device
Once the protective cap
has been removed from
the stationary tank’s
filling connector,
position yourself in front
of the tank, in other
words, in front of the
condensate collector, in
order to protect yourself
from the flow of cold
oxygen. This will also
prevent the oxygen
released through the
tank's air vents during
filling from accumulating
in your clothing and
posing a potential fire
hazard later on.
Line up the green markers found on
both the FREELOX PORTABLE and
stationary tank (if this is a FREELOX
RESERVE). Position and fit the
FREELOX PORTABLE vertically into
the base, as shown in the photo. The
FREELOX PORTABLE's female
connector must be opposite the
stationary tank's male connector.
Use both hands to exert
vertical pressure on the
FREELOX PORTABLE,
in the direction of the
filling connector, until the
FREELOX PORTABLE
is fully connected to the
stationary tank.
Maintain this pressure using one hand,
and with the other hand, open the vent
valve lever completely using a moderate
amount of pressure.
A low hissing noise caused by the
escape of gaseous oxygen will be heard
throughout the filling process.
The FREELOX
PORTABLE is full
after approximately
one minute, when the
hissing caused by
the escape of gas
changes and a thick
white vapour is
released from the
stationary tank's
cover.
Hold the FREELOX PORTABLE by
its top part and push the ejection
button.
After disconnection, the gas released
from the FREELOX PORTABLE
should stop in a few seconds.
While holding the FREELOX PORTABLE upright, put the felt and the condensate collector back in place under the
FREELOX PORTABLE. Put the protective cap back in place on the RESERVE’s filling connector.
Once all these steps have been carried out, leave the device to stabilise for one hour before use.
Warning: after disconnection, do not touch any cold or frosted parts (the connectors on the
RESERVE and the FREELOX PORTABLE).
In the event of a liquid oxygen leak after the disconnection of the FREELOX PORTABLE, reconnect
the two tanks immediately. After a few seconds, separate them again. If the leak persists, reconnect
them and ask the service provider to service the unit. Never attempt to stop a leak by pouring water
onto the RESERVE’s filling connector.

them on your face.
Adjust the flow rate (1)
to the value prescribed by your doctor.
Make sure that this
flow rate adjustment button is always accessible.
Warning: no oxygen is supplied if the flow rate valve (2) is positioned between
two numbers ( )!
After each use, rinse, wring and dry the felt located in the condensate collector
container located underneath the FREELOX PORTABLE .
7.4. Checking the fill level
FREELOX PORTABLE equipped with a V4 electronic level gauge (photo
opposite): on the electronic level gauge, press the level button for at least two
seconds to display the level.
Note
The oxygen level shown on the gauge will be incorrect if the FREELOX PORTABLE is in a tilted position. The
FREELOX PORTABLE must always be used in an upright position.
The level indication threshold can be programmed by the service provider.
When this threshold is reached, the display flashes and an audible beep sounds every minute.
After five minutes, the beep will stop automatically to preserve battery life.
7.5. Stopping the device
The device is stopped by switching the flow rate adjustment button to 0.
Ensure the device remains upright.
7.6. Checking the battery for the FREELOX PORTABLE with V4 electronic level gauge
The red indicator light (A) shows how much battery charge remains:
Steady red light: acceptable battery charge.
Rapidly flashing red light (5 times/sec) : schedule the replacement
of the battery
Slowly flashing red light (2 times/sec) : gauge not working. Contact
the service provider.
Indicator light off: battery not working or missing.
7.7. Are you ready to go out with your FREELOX PORTABLE?

10.5. Impossible to disconnect the FREELOX PORTABLE from the RESERVE after filling
Use the RESERVE’s ejection system. If this does not suffice, wait a few minutes and then try to disconnect the

connection and put the cap back on.

(9 V alkaline LR6 battery).
- Put the battery and its connector back in their
compartment, taking care to position the deflector
over the battery.
- Close the battery cover (1) until it clicks shut.
- On the level gauge, check the battery charge by
pressing the test button, and make sure that the
light is continuously displayed.
