10. FILTER MAINTENANCE
Maintenance differs by method and time of intervention depending on the type of filter:
a) replacing the filter fibre in fabric pre-filters
b) washing pre-filters and the electrostatic cell
c) maintenance of the FI Ionisation and FX Ozonisation sections
d) replacing the activated carbon
e) washing the droplets separator or turbulator
These operations are very important and must be carried out with great care to always keep your equipment
active over time.
10.1
WASHING THE METAL + SPONGE PRE -FILTER
open the galvanised sheet frame
remove the sponge and metal pre-filter
components
Wash the separated parts with a degreasing
detergent in hot water
Squeeze the sponge and let the metal pre-
filter and frame drip
Put the components back in the frame
close the frame
put the filters back in
If the sponge or metal pre-filter are worn, replacement is recommended
10.1 WASHING THE PRE-FILTER AND ELECTROSTATIC FILT ER
To perform correct maintenance, as the first operation, extract the pre-
filter incorporated in the electrostatic cell by lifting it for about one
centimetre and extract it as shown in the figure. For cleaning, prepare:
1) a plastic or stainless steel tank with decanting bottom
2) detergent (we recommend the one supplied by the manufacturer of
the machine).
3) protective gloves and glasses
4) suitable clothing.
5) running water.
Set up a stainless steel frame that keeps the filters raised from the base
of the tank to obtain a sludge settling bottom. Prepare the tank with
warm
(maximum 45 °C) or cold water depending on the type of detergent
being used. Add the diluted detergent according to proportions shown on
the label of the can and proceed:
a) immerse the electrostatic cell in the tank
b) allow it to soak for the amount of time indicated in the instructions for
use of the detergent or until the total all of the dirt has dissolved from the
cell
