10.3 Check air outlet
In order to ensure the correct function of the room air cleaner, it must be ensured
that no objects are placed on the air outlet opening and cover it. In areas with a lot
of public traffic, such as medical practices or schools, we recommend to carry out
the maintenance interval in shorter intervals (depending on the public traffic).
1.) Visual inspection of the air outlet. Make sure that no objects, including
magazines or similar, are placed on the grille of the air outlet. If necessary, re-
move these objects.

3.) Visual inspection of the area below the grid. If objects are visible underneath
the grid, the room air cleaner must be safely put out of operation. Then the ob-
jects must be removed. See Chapter Remove objects below the air outlet grid
