9.23 Reconfigure sample gas return line
Note
In the U.S., it is not permitted to return sample gas to the breathing circuit.
Sample gas return is directed to the scavenging system as a factory default. Perform
the following to reroute the sample gas back to the breathing system. Refer to “Tubing”
on page 11-11.
1. Remove the tabletop (Section 9.4).
2. Port 4 ( A ) of the ABS breathing system
is connected to the expiratory circuit,
downstream of the expiratory check
valve. As a factory default, Port 4 is
plumbed with a length of tubing that is
plugged (
B ) at the far end.
3. Remove the plug from the tube.
4. Find the sample return line at the left-
rear corner of the pan assembly. The
sample return line includes an inline
connector (
C ) at the point where the
sample line goes down into the vent
engine housing.
5. Separate the scavenging tube,
removing the inline connector from the portion of the tube that extends into the vent
engine housing. Plug the open end of the scavenging tube with the plug removed in
step 3.
6. Insert the inline connector from the sample return port into the open tube to Port 4.
Pull on the connector to ensure that it is securely connected.
7. Replace the tabletop.
8. Perform the checkout procedure (Section 3).
