Connection
The coupling ring B has a diameter of 120mm. The air must be vented out by means of a pipe with an internal diameter of 120mm. A non-return fume valve (120 mm diam.) is available on request, at an extra cost. This fits in the coupling flange.
Internal recycle version
�The air is purified through an active carbon filter and returned to the room. �The use of an active carbon filter is necessary when an exhaust pipe to the exterior is not available, or when it is not possible to install this type of pipe. In the case of the internal recycle version proceed as follows: a) Request an active carbon filter suitable for this model from your supplier. b) Remove the grill by turning knob A (fig. 3). c) Place the filter on its seat (fig. 4) and rotate in clockwise until it stops. d) Replace the grill. In this version vapour and fumes will be exhausted on the top of the cupboard where the hood will be mounted through an exhaust pipe with an internal diameter of 120 mm.
Attention
Le non respect des normes d�entretien de l�appareiI et de remplacement et nettoyage des filtres comporte des risques d�incendie. Nous recommandons donc vivement de respecter ces instructions.
