S&P UVF ECOWATT Series Manual page 27

The microfi lters used in the UVF-ECOWATT are high effi ciency fi lters which can not be cleaned.
Cleaning these fi lters could damage them and affect the degree of fi ltration.
Disassembly the prefi lter:
Rotate the lower locks with triangular
shape (a) which hold the prefi lter.
To release the fi lter or fi lters, loosen the two threaded knobs
that hold each support (a), and move the arms until leaving
enough space to remove the fi lter or fi lters (b).
Release the prefi lter, making it slide by the
guides (2).
Remove used fi lters and
replace them by new
ones, respecting the air
sense, indicated by an
arrow in the fi lter frame.
