Adjustment of the fi lter maintenance period
It is possible to set the period to 6, 9, 12, or 15 months (12 month factory setting). The fi lter clogging depends on the
pollution of the area where the unit is installed. We recommend checking the time in which the fi lter clogs and adjus-
ting 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 representative. During the second fi lter check, if you notice that the fi lters are clean you can increase
the time, if you notice the fi lters are very dirty you should decrease the time.
Lift the cover of the control and adjust the timer as shown. To do this set the dipswitches 1 and 2 as in the drawings
below.
