• With the cannula on, close your mouth and
breathe only through your nose to verify that
the H300-50 Portable has stopped pulsing.
5. The H300-50 Portable does not fill.
• Verify that there is oxygen in the Reservoir.
If the Reservoir has a pressure gauge, make
sure it reads between 47-psi and 58-psi.
• Ensure that the H300-50 Portable and
Reservoir fill connectors are fully engaged
throughout the filling process.
6. The H300-50 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, care-
fully remove the H300-50 Portable by gently
rotating the Portable counter-clockwise and lift-
ing from the Reservoir. Venting from the bottom
of the H300-50 Portable will stop in a few min-
utes. Keeping the H300-50 Portable upright,
allow it to warm until you can close the vent
valve. The H300-50 Portable may require as
much as 60 minutes to restore adequate pressure
for proper oxygen flow.
