4.7.4 Dirty filter sensor
The level of air filter clogging is checked by means of a differential pressure switch that measures the pressure drop
between upstream and downstream of the filter.
The control panel will signal, via an alarm on the display, the need to replace or clean the filter. The machine will
continue to work in any case.
The cut-in value is factory set and can be changed on the installed unit by turning the knob with graduated scale
using a screwdriver.
The fouling of the filter may cause a decrease in the flow rate and therefore of the machine's
performance; restoring the filter as quickly as possible from the time of reporting is recommended.
4.7.5 Air filters G4
The units are fitted with "G4" filters on the air supply side. To replace the filters, open the panel of the unit that shows
the indication for access to the filters.
Cleaning or replacement is essential to ensure good operation of the unit and the correct air flow rate.
We reserve the right to make changes without any prior notice.
