1. Safety Guidelines
1. Follow the installation instructions.
2. Use the appliance
• according to its intended use
• in good condition
• with due regard to safety and risk of danger.
3. Note that the appliance is exclusively for use in the appli-
cations detailed in these installation instructions. Any other
use will not be considered to comply with requirements
and would invalidate the warranty.
4. Please take note that any assembly, commissioning,
servicing and adjustment work may only be carried out by
authorized persons.
5. Immediately rectify any malfunctions which may influence
safety.
2. Functional description
The filter combination integrates a pressure reducing valve
and a rinsable fine filter cartridge in one appliance.
During normal operation, water flows through the filter mesh
to the body outlet. To rinse the filter, the ball valve is opened
which discharges the dirt particles. A continous supply of
filtered water is available also during the rinse cycle.
The integral pressure reducing valve functions on a balanced
force principle whereby the force exerted by a diaphragm is
balanced against the force of an adjustment spring. The inlet
pressure has no influence on opening or closing of the valve.
Inlet pressure fluctuation does not therefore affect the outlet
pressure.
3. Application
Medium
Water
Inlet pressure
FK06-...AA max. 16.0 bar
FK06-...AAM max. 25.0 bar
Outlet pressure
1.5 - 6.0 bar
The filter is constructed for drinking water installations. In
case of a process water application the filter has to be proven
individually.
In applications where UV radiation and solvent vapours
are present, use the brass filter bowl!

7. Assembly
7.1 Installations Guidelines
• Install in horizontal pipework with filter bowl downwards
o This position ensures optimum filter efficiency
• Install shutoff valves
• Ensure good access
o Degree of contamination can be easily seen with clear
filter bowl
o Simplifies maintenance and inspection
• The installation location should be protected against frost
• Fit immediately after water meter
o Corresponds to DIN 1988, Part 2
7.2 Assembly instructions
We recommend to install an inlet non-return valve
(accessories)
Observe the flow direction when mounting the backflow
preventer.
When using soldering connections, do not solder the
connections together with the fil-ter combination. High
temperature will irreparably damage important internal
working components!
1. Thoroughly flush pipework
2. Fit filter combination
o Note flow direction
o Install without tension or bending stresses
3. Set outlet pressure
7.3 Drain for rinse water
The rinse water must be piped to the drain in such a way
that no back pressure can oc-cur
1. Discharge into drain connector
2. Discharge into floor drain
