18.6 Maintenance and Cleaning

18.6.1 Occlusion handling

If the AG module passage is occluded, the screen will prompt “AG OCCLUSION”.

Following are a few examples of occlusion, which you may remove one by one until this

message disappears.

Entrance occlusion

If the part at the entrance such as the filter, sample line or airway adapter is occluded by the

condensed water, the system will prompt on the screen that the airway is occluded.

The optimal method to remove clogs of this kind is:

•

Check the filter for clogs. If it is clogged, replace the bacteria filter at the entrance.

•

Check the sample pipe for clogs or knots. Replace it if necessary.

•

Check the airway adapter for water. If necessary, drain the water and install the adapter

again.

Internal Occlusion

If the interior of the AG module is contaminated by the condensed water, the system will

prompt on the screen that the airway is occluded.

The optimal method to remove clogs of this kind is:

Check, as usual, the entrance or the exit for clogs, and remove them if any.

If the occlusion still exists after step 1, check for the existence of interior occlusion. In

this case, contact our Customer Service.
