2.6 Safety Features:
Ø Compressor Motor: Thermal safety is ensured by a thermostat
situated in the stator winding (135°C/ 275 °F). A safety relief valve
is fitted to the compressor outlet and is calibrated to 280 kPa
(40 psig).
Ø Power Failure: In the event the unit is operating and a loss of
power occurs, an audible single - pulse intermittent alarm will
activate.
Ø Oxygen Monitor: The oxygen monitor detects any drop in
concentration below 82% (±3%) and activates a visual alarm
(amber LED indicator on front panel). If the concentration continues
to operate below 82%, an audible 2 - pulse intermittent alarm will
also activate.
Ø Hi Pressure: An over-pressure safety feature prevents potential
damage to device components at a pressure of 207 kPa (30 psig
(± 2 psig)). An audible 4-pulse intermittent alarm will activate.
Ø Low Pressure: An audible 3- pulse intermittent alarm will activate if
the device pressure reduces to
≤
35 kPa (5 psig (± 1 psig)).
Ø No Flow Warning: An obstruction to the flow of oxygen, such as
a pinch or kink in the delivery cannula, will activate an audible
6-pulse intermittent alarm.
