We recommend that you wear gloves during installation and maintenance.
When installing an extracting version (the extracted air is sent outside = Fig. A), it is important to:
- prepare an air exhaust hole and duct with a diameter of 150 mm.
- use a duct that is as short as possible
- use a duct with the least number of curves possible (maximum curve angle 90°)
- avoid the use of flat ducts and ducts of different section as much as possible
- use a duct with the smoothest possible interior and conforming to the standard
- do not connect the hood to a duct that exhausts fumes produced by combustion (fireplaces, boilers, ovens, etc.)
- do not discharge the air into a cavity in the wall unless the cavity has been prepared for that purpose.
- provide the room with air intakes so that the hood does not create negative suction (no higher than 0.04 mbar).
When installing a filtering version (the extracted air is returned to the kitchen = Fig. B) there is no need to prepare a
hole and exhaust duct, but you must provide two activated carbon filters (request them separately as an accessory).
Fig. 1: using the fixing bracket (1), mark the positions of the fastening holes on the ceiling.
Fasten using no. 2 anchors Ø 8 + no. 2 screws Ø 4.8x38 + no. 2 washers.
Fig. 2: attach the cover with grill (2) to the fixing bracket (1). (If you wish this cover can be omitted in the extracting
version).
