Weight Installation location
see table "Dimensions and weights" Standard: horizontal inwards flow; switching
head not recommended underneath; other installation positions are possible; the
installation position affects the switching point and range.
Ranges Details in the table correspond to horizontal inwards flow with decreasing flow rate.
