INSTALLATION
Remove the grease filters before installing
the product, in order to avoid to damage the
appliance.
Open the glass by rotating it as shown in fig.
3; then remove the grease filters by acting
on their specific handle and rotate them to
remove them from their seating (fig. 4).
Make an opening on the kitchen cabinet bot-
tom of the following sizes:
SL921 520: 500mmX270mm
SL921 780: 760mmX270mm
Make sure the cabinet structure and the ma-
terial used allow you to make this opening
without causing any damages, even during
the appliance installation.
Prepare the power supply inside the cabinet.
Prepare the air discharge hole for the pro-
duct being installed either in the sucking or
filtering mode.
Use an air discharge pipe whose maximum
length does not exceed 5 meters.
Limit the number of elbows in the piping, as
each elbow reduces the air capacity of the
hood of about 1 linear meter. (Eg.: if you use
no. 2 x 90° elbows, the length of the piping
should not exceed 3 meters).
Avoid abrupt direction changes. Use a
150mm constant diameter pipe for the who-
le length. Use piping approved standards in
force.
Place the appliance inside the cabinet and fix
it by inserting the screws supplied into the
holes, as shown in fig. 5.
Both in the front and rear side of the ap-
pliance.
Rear air outlet
Models equipped with only one motor can be
installed having the motor air out let orien-
ted towards the appliance rear side.
If you choose this option, you will need to
remove the motor support by removing the
18 screws (fig. 6), taking out and rotating
the support, placing it in its housing , always
keeping the air outlet oriented towards the
appliance rear side. (fig. 7).
Secure it by using the screws previously re-
moved.
Blocking of the stop valve
Warning! Before connecting the flexible
exhausting pipe to the motor, make sure the
stop valve, which is on the air outlet of the
motor, can swing.
Exausting version
Connect the flange to the exhausting hole
with an appropriate pipe. Connect the ap-
pliance with the electrical mains through the
supply cord.
Filtering version
Connect the flange with a pipe suitable to
convey the air to the top of the cabinet. Con-
nect the appliance with the electrical mains
through the supply cord.
