large foreign objects out of the outdoor air (A).
1 x ISO ePM1 50% (F7) filters - complies to ISO 16890 fine filter; filters microscopic pollen and dust particles out of
the supply air (B).
The coarse filter; filters the extract air and keeps the heat recovery cell clean (C).
The filter replacement interval depends on the ambient particle concentration. It is recommended that the filters are
replaced every spring and autumn or at the very least once a year.
