Indicator of filter box clogging - signalisation of need for filter box replacement
-
The orange indicator activates when the filter box is clogged. At the same time, it informs the user about
the need to replace the filter box (box replacement is described in the chapter 7.1.2. filter box
replacement).
-
The indicator activates automatically depending on the current, actual clogging of the filter box, which is
set by the manufacturer.

One of the parameters that affect the activation of the indicator is also power-flow the whole unit is
operated at. In general, the smaller the power-flow of the unit, the longer the time for indicator activation
(the less air is filtered).
