Remove the exhaust tubing from the exhaust port of the
generator.
Occlude the prongs and set the CPAP level to 5 cmH
approximately twenty (20) seconds for the valves to stabilize.
Occlude the exhaust port and verify that the pressure and flow
immediately go to zero and a 'High Pressure' alarm activates.
After three (3) seconds, flow will reinitiate.
Remove the occlusion from the exhaust port and allow
approximately 10 seconds for the valves to stabilize. Verify
CPAP level is at 5 ±1 cmH
Press the Alarm Mute/Clear button to clear the 'High Pressure'
alarm.
Replace the exhaust tubing into the exhaust port.
Occlude the prongs and set the CPAP level to 5 cmH
approximately twenty (20) seconds for the valves to stabilize.
Remove the occlusion of the prongs.
Ensure that a 'Disconnect' or 'Low Pressure' alarm activates.
If a 'Disconnect' alarm is active, verify that the flow is within ±2
LPM of Target Flow.
If a 'Low Pressure' Alarm is active, verify that the flow does not
exceed 3 LPM over Target Flow.
Occlude the prongs and verify that the CPAP level returns to 5
±1 cmH
O within ten seconds.

Occlude the prongs and set the Target Flow to 13 LPM.
Remove the patient Pressure Line to generate Disconnect and
Low Pressure alarms. Allow approximately twenty (20)
seconds for the valves to stabilize.
Verify that the Driver flow reading is between 13 ±2 LPM.
