4.5. How to load the media filter
The media filter must be loaded inside the vessel afterthat the placing of the filter is
completed or in the case the media have to be replaced.
Open both the side man-holes
Check that the filter nozzles are correctly fixed and not damaged.
Load the supplied quartz-sand (2-3 mm size for FC/D filters, 1-2 mm size for FAC/D filters)
into the vessel, through the lower man-hole, until the sand covers completely the filter-
nozzles. Make a flat surface of the sand using a wooden tool, in order to avoid any damage
to the coating of the vessel.
Close the man-hole, after checking the integrity and correct position of the gasket, by
tightening the nuts.
Load the rest of supplied media filter into the vessel, through the upper man-hole (or through
the upper head, see components drawing). The media filter are shipped separately; check
that the shipped and available quantity complies exactly with the quantity listed in the Weight
Table (see § 3.5 pag. 6).
Filtering media must be loaded, one after the other one, and according to the following order:
quartz sand 2÷3 mm (only for filters FC)
quartz sand 1÷2 mm
quartz sand 0.4÷0.7 mm (only for filters FC)
anthracite (only for filters FC)
activated carbon (only for filters FAC)
Take care to make a flat surface of each layer of sand, before load the next one.
After completed the loading, close the upper man-hole (or upper head), after checking the
integrity and correct position of the gasket, by tightening the nuts
4.6. Electrical wiring connections
Make the electrical wiring connections inside the control panel, as below explained (see also
WIRING DIAGRAM).

A free voltage contact for remote segnalation of running regeneration (max 1 A, max 24 V) is
also available, directly on the output Q4 of the programmer.
DUAL arrangement only :
the free voltage contact of output Q4 of the programmer reports the running regeneration of
column A, while the running regeneration of column B is reported by free voltage contact of
output Q4 of expansion card
It is also possible to inhibit the starting of regeneration by mean of a free voltage external
contact. It will be connected to one of any clamp + and the input I2 of the programmer.
