It is possible to set the period to 6, 9, 12 or 15 months (12 months factory setting). The fi lter
clogging depends on the pollution of the area where the unit is installed. We recommend chec-
king the time in which the fi lter clogs and adjusting this period. It is advisable to do this after the
second fi lter change. Of course, after the installation, the extract air is dusty and not represen-
tative. During the second fi lter check, if you notice that the fi lters are clean you can increase the
time (9 or 15 months), if you notice that the fi lters are very dirty you should decrease the time
(6 months).
Open the box and adjust the timing as shown. To do this, set the micro contacts 1 and 2 as
shown in the drawings below to adjust the month.
