Low-pressure leak testing the machine
1. Remove the breathing system from the machine.
2. Attach the Machine Test Tool (using only the Thru Port) and the low-pressure leak test
device to Port 3 of the breathing system interface as shown above.
Note: To prevent damage to the airway pressure transducer, ensure that the gauge
port (Port 1) is not connected to the Test Tool.
3. Access the Ventilation Schematic (Section 12.3.3) of the Service Application.
4. Ensure that the Circuit Setting shows is set to Circle.
• For machines with an ACGO outlet, ensure that the ACGO selector switch is set to
the ABS (circle breathing circuit).
5. Compress and release the bulb until it is empty.
6. If the bulb completely inflates in 30 seconds or less, there is a leak in the low-
pressure circuit.
