: Do not place the oxygen concentrator in surroundings where its airflow is obstructed.
: Do not place items on top of the concentrator.
: Always place the concentrator on a hard surface. Never place the concentrator on a
surface such as bed or couch, where the concentrator may tip or fall.
: NEVER leave the concentrator unattended when plugged in.
: Always ensure that both the intake and bottom exhaust vents remain clear of
obstruction. Obstruction of either air intake or exhaust venting during operation can
permanently damage your concentrator.
: It may take up to 5 minutes for the Oxygen Concentrator to reach regular function
and normal performance.
NOTE: If oxygen does not seem to flow, first verify that the flowmeter ball is registering a flow.
Then, place the tip of the cannula into a glass of water; if bubbles come out of the cannula,
oxygen is flowing. If bubbles do not appear, turn off the oxygen concentrator immediately
and refer to Troubleshooting.
NOTE: There is never a danger of depleting the oxygen in a room when you use your
oxygen concentrator.
Radio Frequency Interference
Most electronic equipment is influenced by Radio Frequency Interference (RFI). When
there is strong electromagnetic interference, the LCD may be slightly affected, but the
oxygen concentrator is still running. ALWAYS exercise CAUTION with regard to the use of
portable communications equipment in the area around such equipment.
