After the Wash
After the wash, the sippers remain in the down position to prevent air from entering the system. Leave
the cartridges in place until the next run.
Replace Air Filter
The air filter ensures air flow through the instrument. The NextSeq 550Dx Operating Software in the
diagnostic mode of the instrument displays a notification to change the air filter every 90 days. When
prompted, select Remind in 1 day, or follow the following procedure and select Filter Changed. The 90
day countdown resets following Filter Changed selection.
1 Remove the new air filter from the package and write the date you install it on the frame of the filter.
2 On the back of the instrument, press down on the top of the filter tray to release the tray.
3 Grasp the top of the filter tray and pull up to lift the tray completely out of the instrument.
4 Remove and discard the old air filter.
5 Insert the new air filter into the tray.
NOTE
The air filter does not work correctly if it is backwards. Make sure to insert the air filter into the tray
so that you can see the green "Up" arrow, and cannot see the warning label. The arrow should
point towards the handle of the filter tray.
6 Slide the filter tray into the instrument. Push down on the top of the filter tray until it clicks into
place.
