Installing filter (with recirculating and hybrid
operation)
The BackFlow port (Ø 150 mm) is located on the fan housing
as an aid for the installation of the filter.
The filter is placed correctly when the bottom edge of the
filter is parallel to the top edge of the fan‘s housing and the
gap is approximately 3 mm wide.
If accessories are connected, the filter must be positioned at
a slight angle so that connector interference does not arise
when it is fitted.
