3. Connecting the filter
discharge to drain
Connect a rubber tube reinforced with canvas to the drain
funnel or hose fitting at the base of the filter, secure with a
clamp and have it discharge into the drain ( figures 4A and 4B).
The drain point must be lower than the drain funnel or hose
fitting. The rubber tube reinforced with canvas must not be
more than 2 metres long.
WARNING
Avoid bending or pinching the rubber tube reinforced with
canvas.
4. Filter start-up
Proceed as follows:
• By gradually opening water supply to the filter, make sure
there are no water leaking.
• Gradually fill the filter to about full and then release air in
the filter as following: by opening the vente valve on the
head of the filter.
Now the filter is ready for proper functioning.
WARNING
Only use self-cleaning filters to filter mains or well water and to
filter sand and other large impurities from water with pH levels
between 6.5 and 9.5. Do not use the filter to filter silt. Do not
filter other liquids.
Self-cleaning filters do not make water drinkable. Do not use
the filtered water as drinking water unless water quality is
known.
WARNING
Make sure that there are no water leaks from the product, and
especially control the tightening between the housing head
and the housing bowl. Continue checking that the tightening is
good and there is no water leakage for 48 hours following the
installation and start-up. In case of leakage, open the housing,
remove the o-ring from the bowl, place a new o-ring and apply
lubricant, then re-tighten the bowl to head and repeat the
leakage check as above. Ask your vendor for o-rings, lubricant
and other spare parts.
Remark: after the installation, slowly turn on a water supply
(tap) downstream the installed unit and let the water flow for at
least 5 minutes before the use.

5. Routine maintenance
Clean the filter cartridge with back-wash in counter-current
operation by opening the drain valve for 15/20 seconds.
Repeat the operation with the same procedure one or more
times until the desired cleanliness is reached. If acceptable
cleanliness is not achieved for a good filter operations, follow
the extraordinary maintenance procedure as described here
following.
Notes for a proper routine maintenance:
1. Carry-on the routine maintenance before the pressure
difference between the inlet and outlet manometers
exceeds 1 bar.
2. For mains water we recommend routine maintenance at
least once a week.
3. For well water we recommend routine maintenance
several times a week.
WARNING
During cleaning operations discontinue the water supply by
closing faucets or the by-pass faucet downstream from the
filter to reach maximum pressure in counter-current and the
best cartridge cleaning results.
6. Extraordinary maintenance
In time, extraordinary cartridge cleaning is required as follows:
• Shut-off water flow upstream from the filter.
• Release the filter pressure by opening a tap downstream
the filter.
• Open the filter by unscrewing the bowl from the head
using the supplied spanner.
• Remove the cartridge.
• Clean the cartridge under a jet of cold water and use a soft
brush to remove impurities.
• Insert the clean cartridge in the bowl.
• Screw the bowl onto the head.
• Follow the procedure under "FILTER START-UP" to put the
filter in service.
WARNING
At re-start after every maintenance operation, when the filter's
bowl is unscrewed from head, change the o-ring with a new one
and carefully lubricate before tightening the bowl to the head.
Make sure that there are no water leaks from the product and
especially control the tightening beteween the housing head
and the housing bowl. Continue checking that the tightening is
good and there is no water leakage for 48 hours following the
installation and start-up. In case of leakage, open the housing,
remove the o-ring from te bowl, place a new o-ring and apply
lubricant, then re-tighten the bowl to head and repeat the
leakage check as above. Ask your vendor for original o-rings,
lubricant and other spare parts.
