Important
The unit is a “C type” with sealed chamber and forced draught; the air inlet and fume outlet must be connected to one
of the extraction/suction systems indicated below. Before proceeding with installation, check and carefully observe the
above instructions. Also, comply with the provisions on the positioning of wall and/or roof terminals and the minimum
