Device warning label and alarm display.
• Compressor Motor: A pressure relief valve is
fitted to the compressor outlet and is calibrated to
280 kPa (40 psig). Thermal safety is ensured by
a thermostat situated in the stator winding of the
compressor (135°C / 275 °F).
• General Malfunction: If any of the conditions
listed below occurs, 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, trig-
gered by high product tank pressure
• High device product tank pressure condition
of greater than 33psig (±1)
• Low device product tank pressure condition
of less than 5psig (±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)
