Filter box replacement
-
The filter box may contain dust particles, bacteria and viruses, so it is necessary to use appropriate
protective equipment to prevent contamination or contact with harmful substances. When carrying
out any work with the filter box, we recommend to use at least disposable polypropylene gloves and a
fine dust protective mask (protection level 3).
-
The need for replacement of the filter box is indicated on the main control panel by the orange indicator
for filter box clogging
-
The indicator activates whenever the filter box is clogged as set by the manufacturer.
