4. Chose operation time for filter
(fig. 12) . Standard factory setting is 9 months. This is sufficient in areas
where the outdoor air has a satisfactory quality. If the outdoor air is polluted by exhaust from traffic,
industry etc, filter change every 6 months is recommended. Even if the outdoor air quality is good, and
the fresh air filter is not clogged, maximum recommended operation time for filters is 12 months
