Startup
Check the filter for proper installation.
The stop valves must not yet be opened. Check
the transparent cylinder (3) for proper fit and close
the discharging screw (4). Please do not use tools.
Manual fastening of the screw is sufficient.
Slowly open the stop valves before and after the
filter and deaerate the pipework at the bleeding
point closest to the filter (after the filter).
Operation
The filter must be checked at regular intervals, i.e.
every two months (according to DIN 1988).
Water is a consumable liquid. When exchang-
ing the filter, proper hygiene must be ensured.
Exchanging the filter element
The filter element must be replaced if due to in-
creasing dirt accumulation on the filter cloth there
is a noticeable drop of the water pressure, or after
6 months at the latest (according to DIN 1988).
A Close the stop valves before and after the filter
and provide a collecting basin under the filter.
Open discharging screw (4) for pressure relief
and empty the filter.
B Open transparent cylinder (3) manually (no
tools!), remove filter element (5) and dispose
of it.
Clean the transparent cylinder.
The plastic parts may only be cleaned with a
soft, damp cloth. Do not use any solvents or
detergents nor acid cleaners.
C Leave the plastic bag on the new filter element
when holding it. Open the bag at the insertion
end of the filter element.
D Insert the filter element (5) into the top section
(1).
E Remove the plastic bag. Make sure not to touch
the filter element with your hand.
F Screw the transparent cylinder (3) into the top
section (1) and fasten it manually. Close the dis-
charging screw (4).
G Slowly open the stop valves, first those before,
then those after the filter. Check the filter for
proper sealing (visual inspection) and then
deaerate the pipe at the bleeding point closest
to the filter (after the filter).
Maintenance
All technical equipment requires regular mainte-
nance. According to DIN 1988, maintenance must
be carried out by expert technical staff who also
replaces the parts subject to wear and tear. We
therefore recommend closing a maintenance con-
tract.
Maintenance must be carried out once a year, or
twice a year for communal installations. It is to be
carried out by the installer or manufacturer.
Warranty
In the event of malfunction during the warranty
period please contact our Customer Service and

(see Specifications or rating plate).
Any warranty work may only be carried out by
our Customer Service.
Warranty work to be carried out by an external spe-
cialist firm requires the express consent of our Cus-
tomer Service Manager.
