Installation
Before fitting the extension piece remove the protective foil.
Screw the extension piece firmly to the upper retaining plate at each side with two 3.9 x 7.5 mm screws.
Bend the top hanging retainers ap- prox. 45° inwards. This makes fitting easier.
RecirculationExtraction
Pull the extension piece slightly outwards and push over the upper retaining plate.
For recirculation make sure that the openings in the extension piece are po- sitioned at the same height as the air outlets in the directional unit of the fan motor.
Only with recirculation mode: Fit the recirculation grilles into the extension piece and into the directional unit be- hind so that the slats point down- wards.
