Maintenance Filters The unit is supplied with two G3 pre filters. If required, an F7 filter (FBP200+FBPF7) can be installed in the supply side for extra filtration. Alternatively a standard EU2 filter can be used (FBP200+FBPF2). Cleaning the filters The internal filters are designed as secondary filters (there should be extended surface filters cleaning the air before reaching the unit). However, when unit filters are heavily soiled, wash or replace the filter material with "HexFilter" (234x380mm) or "HexFilter 222" (222x380mm) for 2015 and earlier models. To wash: use vacuum cleaner to remove excess dust, then wash in warm detergent treated water, keep filters flat or leave in frame to wash.
