Filter start up
Proceed as follows:
•
make sure there are no water leaks by gradually opening
water supply to the filter;
•
gradually fill the filter to about full and then release air in
the filter by opening the breather screw on the head of the
device. Close the breather screw when finished.
The filter is now ready for correct use.
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 installa-
tion 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.

Routine maintenance
Self-cleaning pre-filter (figures 1, 2, 3):
Clean the filter cartridge in counter-current by opening the drain
valve for 15/20 seconds.

cleanliness is not achieved for good filter operations, follow the
extraordinary maintenance procedure described below.
WARNING
During cleaning operations discontinue the water supply by
closing faucets or the bypass faucet downstream from the filter
to reach maximum pressure in counter-current and the best
cartridge cleaning results.

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 retighten the bowl to head
