Step 6: Install the required filters
Verify proper installation of the prefilters located on special counter-frames with safety springs or guides.
After removing the filters from the packing (that they are placed in to prevent deterioration during trans-
port and at the installation site), insert them into the containment section, paying attention to ensure a
rigid assembly and a perfect seal of the gaskets.
Remove the filters from their packaging only when ready to install them to avoid getting them
dirty and contaminating them.
Make sure that the inside of the filter is not contaminated by external agents.
This operation should be carried out after the first start-up of the machine, when the ducts are
cleaned of dust and various debris. Proceeding in this way preserves the filtering sections that
cannot be regenerated.

Installation of "pocket" filters and a pre-filter
To protect the components installed inside the unit, make sure that coarse filters (Prefilters) are
installed.
