For filter monitoring, the filter pressure is shown in the display of the controller. If the
display reaches the red area, please exchange pre- or intermediate filter first. If the
display value drops by 100 Pascal or more, the unit can be operated again. If the value
drops by less than 100 pascals, the HEPA filter must be replaced.
