55..33. . Filters and filter replacementFilters and filter replacement
The heat recovery unit contains F7 filters at the air supply as well as exhaust. The need to replace the filters is indicated
automatically. Recommended frequency of their replacement depends on the air quality in the environment where the unit is
used (1× approx. 2 – 6 months). Basic filtration can be supplemented with an optional carbon filter, which is inserted directly into
the unit under the supplied air filter.
Users are alerted to the need to replace filters by:
a change of the color of LED indicator on the front side of the unit (see the preceding table),
