of this manual). If unit ceases to alarm after
a minimum of two minutes and proper flow
appears to have returned, this was the issue.
2. Vents in back
are blocked.
Check the rear cooling vents are not blocked
or restricted. If unit ceases to alarm after a
minimum of two minutes and proper flow
appears to have returned, this was the issue.
3. Blocked
tubing
Detach cannula, catheter, or face mask from
oxygen outlet. If unit ceases to alarm after
a minimum of two minutes and proper flow
appears to have returned, this was the issue.
Check for obstructions or kinks in external
cannula, catheter, face mask, or tubing.
Clean or replace, if necessary.
4. Blocked /
defective humid-
ifier bottle.
Detach the humidifier from the oxygen outlet.
If unit ceases to alarm after a minimum of
two minutes and proper flow appears to

5. Flow meter
set too low.
Turn flow meter dial counter-clockwise to a
minimum of 0.5 LPM or greater. If unit ceas-
es to alarm after a minimum of two minutes
and proper flow appears to have returned,
