3. If there is a slight amount of dirt, clean the filter mat at a suitable location. Depending on the
degree of pollution, you can also clean the filter mats using a vacuum cleaner. If the filter mat
is damaged, or the frequency of alarms increases, dispose of the dirty filter mat in the correct
fashion. Use a new filter mat.
4. Insert the filter mat in the frame of the fan opening. In order that dirt is not drawn in, insert
a clean mat in the same direction as it was installed before the cleaning.
5. Carefully place the louvered cover over the frame.
6. Retighten the cover screws.
