Fit a false ceiling with an opening of the following sizes:
WS952XM: 1050x645 mm with a minimum distance of 250 mm between the

WS958XM: 865x405 mm with a minimum distance of 270 mm between the
ceiling and the false ceiling.
It is possible to select the side of the hood where the air suctioned can be
discharged. After having chosen the most suitable position, prepare the
ducting: an air outlet connection piece, with a diameter of 150 mm to be
installed in the side selected, is provided with the appliance.
Leave any unused exhaust outlets closed. Draw the outline of the hole to
house the ceiling- mounted hood on the solid ceiling (Fig. 1), according to the
model chosen; make 4 holes in the ceiling according to the dimensions shown
in (Fig. 2); place the metric plugs provided in the holes.
Open the stainless steel panels, following the instructions mentioned in the
USES section, and remove the grease filters in order to avoid damaging them
in any way and too allow installation (Fig. 3); screw the threaded bars
provided into the plugs (Fig.4); the threaded bars are 250 mm long and serve
to install the ceiling-mounted hood at a distance from the solid ceiling of
between 270 mm and 370 mm (Fig. 5); in case of a larger gap between the
hood and the ceiling, you need to use longer threaded bars.
