5.3 Adjust Drive Gas Regulator

5-10
The drive gas regulator must be adjusted while maintaining a flow of
15 l/min. To adjust the flow, you must set the system to the Install/Service
mode and use the PC based Service Application to control flow through the
regulator.
The drive gas regulator should provide a constant gas input pressure of
172 kPa (25 psi).
Calibration setup
1. Attach a pressure test device to the regulator pressure port (shown below)
• Remove the 6.35-mm (1/4 inch) plug.
• Attach test device to the open port.
2. Remove the ABS breathing system from the machine to allow continuous
Insp Valve flow through the exhalation valve.
