Functional Tests Periodic Maintenance<br />
6.8.6 Breathing System Checks<br />
6.8.6.1 Waste Gas Scavenger Test (if available)<br />
1. Connect one end of the low pressure waste gas hose to the port on the Waste Gas<br />
Scavenger Assembly. Connect the other end of the hose to the EVAC port.<br />
NOTE: If operating the AS3000 with other types of waste gas<br />
scavenging, ensure that waste gases are directed from the<br />
EVAC port to that scavenging system.<br />
2. Connect the respiratory gas monitor exhaust output to the barbed fitting port on the<br />
Waste Gas Scavenger Assembly.<br />
3. Cap any open ports on the waste gas scavenger assembly.<br />
4. Ensure that the waste gas scavenger flow adjustment is able to be set throughout its full<br />
range.<br />
6.8.6.2 Internal Gas Connections Test<br />
1. Close and remove all gas cylinders from the AS3000<br />
2. Connect only the AIR line pressure hose to the AS3000 from the wall supply. Leave all<br />
other line pressure hoses disconnected.<br />
3. With the AS3000 powered OFF, rotate the AIR flow control knob to ensure a<br />
continuous flow increase throughout its full range<br />
4. Disconnect the AIR line pressure hose from the AS3000, and connect the O 2 line<br />
pressure hose from the wall supply.<br />
5. Fully rotate the N 2 O flow control knob and verify that there is no flow.<br />
6. Fully rotate the AIR flow control knob and verify that there is no flow.<br />
6.8.6.3 Drive Gas Pressure Loss Alarm, N 2O Cutoff Test<br />
1. Set the O 2 flow to 2 L/min using the flow control valve.<br />
2. Set the N 2O flow to 2 L/min using the flow control valve.<br />
3. Set the AIR flow to 2 L/min using the flow control valve.<br />
4. Interrupt the O 2 supply to the AS3000.<br />
5. Verify that the flow of N 2O and O 2 stops within 2 minutes and that the flow of AIR (if<br />
available) continues to flow at 2 L/min.<br />
6. Verify the following alarms are activated:<br />
O 2 Supply Failure appears on the screen<br />
An alarm tone sounds.<br />
