Column Change Procedure

There are two columns (metal tubes) on the concentrator located behind the
particle filter. These two columns will be removed and replaced when service
is required. Ensure adequate time to complete all steps without disruption is
alloted when performing this maintenance.
1. Turn off the concentrator by pressing the power button to shut down the
device.
2. Unplug the concentrator from the electrical outlet.
3. Lay down the concentrator on its side.
4. Press the two latch buttons on the sides of the device to remove the cover
from the bottom of the concentrator in order to access the two columns.
5. Press the latch button with thumb or finger and pull the column out of the
concentrator using the pull ring attached to the bottom of the column cap.
6. Remove the column completely from the concentrator.
7. Repeat steps 5-6 to remove the other column.
Installation of the new columns (metal tubes):
8. Remove the upper and lower dust caps from each column. There should be a
total of two dust caps removed from each column. Make sure there is no dust or
debris where the dust caps were located.
9. Insert the new column into the concentrator . Do not leave the column
exposed after the dust caps are removed; it should be inserted into the
concentrator as soon as the dust caps have been removed, to minimize
environmental exposure.
10. The spring loaded latch button should fully return to the closed position
when the column is completely inserted.
11. Repeat steps 9-10 to install the other column.

13. Connect the power supply cord from the concentrator and plug into an
electrical outlet. Do Not Power On the concentrator.

will be illuminated and column will be reset. Release the plus button.
