Observe all applicable installation regulations, ge-
neral guidelines and technical specifications. Install
the filter in the cold water pipes upstream of the ob-
jects to be protected. Always provide stop valves.
Caution: The installation site must be protected
against frost and must guarantee the protection of
the filter from solvent vapors, fuel oil, lees, chemi-
cals of all types, UV irradiation, and heat sources
see tecnical data. The filters should be according
to the nominal connection width in the same di-
mension fitted in the pipework. Install the filter in
the direction of flow in the vertical or horizontal
cold water pipe.
Caution: Keep plastic parts free of oil, grease,
solvents and acid or alkaline cleaning agents.
Avoid extreme pressure blows (closure-beat by
downstream magnet valve e.g.).
5. Installation
See installation drawing.
Install the filter and the stop valves before and after
the filter in flow direction in the water pipe (see
flow direction arrows an top section).
Route the flushing water connection with hose to
the sewage channel or provide a collection basin
(capacity approx. 10 l). Please note: According to
DIN EN 1988-200, the flushing water hose must be
installed at a miniumum distance of 20 mm to the
highest possible waste water level (free discharge).
6. Startup
Check the filter for correct and proper installation.
The shut-off valves must not be opened yet. Check
the filter bottom part and rinsevalve to ensure cor-
rect fit. Close the rinsevalve. It should not used any
tool. Maximum torque 8 - 10 Nm at recess of plastic
parts in brass parts. Slowly open the shut-off valves
before and after the domestic waterstation and dea-
erate the piping at the next tapping point after the
domestic water-station. Check the filter for leaks.
The pressure reducer is set to a back pressure of
4 bar at the factory. To change the back pressure,
loosen the locking screw (6) and turn the rotary
knob (7). The back pressure can be changed by tur-
ning the setting knob (7) (control range 2 - 6 bar).
Clockwise rotation = higher back pressure.
Anti-clockwise = lower back pressure.
During setting, an outlet valve downstream from the
pressure reducer must be briefly opened and closed
again a number of times. When water is removed,
the back pressure is temporarily reduced. The back
pressure must not exceed 80 % of the response pres-
sure of the hot water safety valve (DIN 1988-200).
7. Operation
The filter must be checked at regular intervals, i.e.
every two months (according to DIN 1988-200)
and also must be rinsed. If there is a noticeable
drop of the pressure, caused by increasing pollu-
tion of the filter cloth, the filterelement must be
replaced. The filterelement must be replaced after
6 months at the latest (according to DIN 1988-
200). Close the stop valves before and after the fil-
ter and provide a collecting basin under the filter.
Open rinsevalve for pressure relief and empty the
filter. Open the filter bottom part with tool (wrench
width 21) or by hand. Clean the filter bottom part.
Exchanging the filter element:
Water is a consumable liquid. When exchanging the
filter, proper hygiene must be ensured. The plastic
parts may only be cleaned with a soft, damp cloth.
Do not use any solvents or detergents nor acid
cleaners. Remove the filterelement and exchanged
against a new filterelement. Place the filterelement
in the top section and screw it with the bottom part.
Close the rinsevalve. Slowly open the stop valves,
first those before, then those after the filter. Check
the filter for proper sealing and then deaerate the
pipe at the bleeding point closest tot he filter (af-
ter the filter).
8. Warranty
In the event of a failure during the warranty peri-
od, please contact your contractual partner, the
plumbing company, stating the appliance type
(see specifications and/or rating plate of the ap-
pliance).
