Corrective Action
Measured inflow is excessive when outflow and scavenging circuits are closed.
If pre-use check also fails with a therapy cassette, replace and retest in the following order:
• Missing, damaged, worn Mechanical Connector Valve o-rings.
• Mechanical Connector Valves
• Valve Block
• Flowmeter Block
NOTE: If pre-use test passes with a therapy cassette the Test Cassette may be leaking.
Replace and retest in the following order:
• Outflow Zero Valve
• Flowmeter Block
• ADB
Replace and retest in the following order:
• Inflow Valve
• Inflow Check Valve
• Backpressure Valve
• Flowmeter Block
• ADB
Replace and retest in the following order:
• Scavenging Valve
• Flowmeter Block
• ADB
If 'Reading' is significantly below ambient pressure, replace flowmeter block and retest.
If 'Reading' is high, manually depressurize cassette and retest.
If failure persists, replace and retest in the following order:
• Flowmeter Block
• ADB
Replace and retest in the following order:
• Check altitude setting (Section 4.3.1).
• Flowmeter Block
• ADB
Replace and retest in the following order:
• Check altitude setting (Section 4.3.1).
• Flowmeter Block
• ADB
Mixer and Vaporizer measured pressures do not agree at the second of two test pressures
(high pressure). Replace Flowmeter Block and retest.
If problem persists, check troubleshooting procedures for Electronic Mixer.
If mixer is not at fault, replace the ADB and retest.
Mixer and Vaporizer measured pressures do not agree at the first of two test pressures (low
pressure). Replace Flowmeter Block and retest.
If problem persists, check troubleshooting procedures for Electronic Mixer.
If mixer is not at fault, replace the ADB and retest.
Replace and retest in the following order:
• Flowmeter Block
• Mixer
• ADB
