Safety Features

The following information will acquaint you with
safety features of the NewLife Oxygen Concen-
trator. Make sure you read and understand all the
information contained in this manual before you
operate your unit. Should you have any questions,
your Equipment Provider will be happy to answer
them for you.
• Compressor Motor: A pressure
relief valve is fitted to the
compressor outlet and is cal-
ibrated to 280 kPa (40 psig).
Thermal safety is ensured by
a thermal safety switch which
will cause the compressor to
shut down (65 °C / 149 °F).
• General Malfunction: If any of
the conditions listed below oc-
curs, the general malfunction
light ( ) will illuminate and
an audible intermittent alarm
will activate. This includes:
• Obstruction to the flow of
oxygen such as a pinch
or kink in the delivery
cannula, triggered by high
product tank pressure
Note: 10 LPM Single Flow Meter Only
• High device product tank pressure condition
of greater than 38 psig (±1)
• Low device product tank pressure condition
of less than 15 psig (±1)
• High device temperature of greater than
135°C (275 °F), triggered by low product
tank pressure if the thermal switch located
within the compressor trips (shutting down
the compressor)
• Oxygen Monitor: The oxygen monitor detects
any drop in concentration below 82%. If this oc-
curs the low oxygen concentration warning light
( ) will illuminate. If the low O2 condition
persists, an audible intermittent alarm will also
activate in addition to the alarm light. See Figure
10.
• Power Failure: In the event the unit is operating
and a loss of power occurs, the power warning
light ( ) will illuminate and an audible
intermittent alarm will activate. See Figure 10.
• Product Filter: ≥ 10 μm filter
Note: New Life Elite and Dual Flow New Life
Intensity—Obstruction to the flow of oxygen such
as a pinch or kink in the delivery cannula will cause
the flow meter ball to drop to zero as an indicator
of no flow.

Oxygen Monitor

The oxygen monitor is a small electronic device
within the NewLife Oxygen Concentrator that
monitors the concentration of oxygen produced
by the unit. If oxygen concentration falls below
the acceptable therapeutic level, a yellow oxygen
monitor light on the Oxygen Concentrator turns on.
If the light remains on for more than 15 minutes, an
intermittent alarm sounds.
Note: When you turn the unit on, it is normal for the
yellow oxygen monitor light to turn on and remain
on for up to five minutes.
Device warning label
and alarm display.

CAUTION: Contact your Equipment
Provider immediately if the yellow
oxygen monitor light remains on for
more than 15 minutes.
