WHEN THE WALL IS THINNER THAN RECOMMENDED, THE SPA-
CERS ON THE FAN UNIT CAN BE SHORTED BY UP TO 25 MM AT
THE CORRESPONDING MARKINGS. IF THIS IS NOT POSSIBLE,
THEN AN OUTSIDE METAL HOOD WILL BE NEEDED.
5.7 Inserting the inside cover
Once all work inside the building has been completed, the inside cover can be installed.
Place the lter unit in the slots for the lter inside the cover. Insert the cover into the
mounting tube, making sure that the air vent points upwards and that the cover sits tightly.
THE UNITS MUST HAVE A FILTER INSERTED BEFORE BEING TURNED ON FOR
THE FIRST TIME.
