VENTILATION THE RIGHT WAY

11 Filter maintenance
The level of soiling of the round filter cartridges is automatically monitored by the ventilation unit. A
pending filter change is signalled audibly roughly 2 to 3 weeks in advance.
As the time for the filter change approaches, the intervals between the audible warnings shorten.
The filters must be changed when the warning signal occurs every hour and lasts for one second.
This long warning period allows the user to order replacement filters in good time. No tools are
needed to change the filters.

11.3 Filter change
NOTE
►
Always replace filters in pairs, at least once per year and ideally before the period of cold
weather. The permeability of both filters affects the efficiency and power consumption of
the ventilation unit.
►
Always switch the ventilation unit off at the mains switch for the filter change. Otherwise
the open air flaps will make it impossible to remove and insert the filter cartridges.
