resideo FKN74CS 1A Primus Plus Filter Combination Pressure Reducer Instruction Manual

Braukmann
FK74CS/FKN74CS
Filter combination
with pressure reducing valve and reverse rinsing fine filter

APPLICATION

The filter combinations comprise a reverse rinsing filter and pressure reducing valve in one appliance. They ensure a continuous supply of filtered water. The fine filter stops the
ingress of foreign bodies, for example, rust particles, strands of hemp, and grains of sand, and thus reduces the probability of corrosion. The pressure- reducing valve prevents pressure damage and reduces water consumption.
The filter combinations are fitted in systems where a pressure-reducing valve is required. Both horizontal and vertical installation is possible.

APPROVALS

• DVGW
• SVGW

approval for all filters with 100 μm mesh sizes and with a rotatable connection piece

SPECIAL FEATURES

• Integral pressure reducing valve with a balanced seat
• Inlet pressure balancing – no influence on outlet pressure by fluctuating inlet pressure
• Filtered water supplied even during reverse rinsing
• Patented reverse rinsing system – fast and thorough cleaning of the filter with a small amount of water
• Memory ring indicates when the next manual reverse rinsing is due
• Automatic reverse rinsing actuator with bayonet the connector can be retrofitted
• Large filter surface
• Shock-resistant clear synthetic material filter bowl enables easy checking of filter contamination
• Filter insert fully replaceable
• Standardized discharge connection
• All materials are ACS approved
• All materials are KTW approved
• Approved by TÜV LGA for low noise, Group 1 without limitations

METHOD OF OPERATION

The filter combination combines reverse rinsing filter and pressure reducing valve in one appliance.
The filter insert comprises an upper part and a lower combination section. When in the „filtering“ position, the small upper filter is closed so that the water can only pass through the main filter from outside to inside. When the ball valve is opened for reverse rinsing, the filter is pushed downwards until the water supply to the outer side of the
main filter is stopped. Simultaneously, the water flow is opened to the upper part of the filter. The water needed for cleaning the filter passes through the upper sieve, the rotating impeller, and the main filter from inside to outside.
By this means, the filter is fully cleaned over its whole surface area at the full inlet pressure. The filter automatically switches over to the operating position when the ball valve is
closed again.
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 the opening or closing of the valve. Inlet pressure fluctuation does not, therefore, affect the outlet pressure.

TRANSPORTATION AND STORAGE

Keep parts in their original packaging and unpack them shortly before use.
The following parameters apply during transportation and storage:

INSTALLATION GUIDELINES

Setup requirements

• The installation site has to be frost-proof and the protection of the device from chemicals, paints, detergents, solvents, and their vapors and environmental influences must be guaranteed

• Install in horizontal or vertical pipework with filter bowl downwards
  • This position ensures optimum filter efficiency

• Install shut-off valves

• These filters are armatures that need to be maintained regularly

• Ensure good access
  • Pressure gauge can be read off easily
  • Degree of contamination can be easily seen with a clear filter bowl
  • Simplifies maintenance and inspection

• It is recommended that a straight section of pipework at At least five times the nominal valve size is provided after the filter (according to DIN EN 806-2)

• Fit immediately after the water meter

• Related to the EN 806-2 it is recommended to install the filter immediately after the water meter

• In order to avoid flooding, it is recommended to arrange a permanent professionally dimensioned wastewater connection
