2. Functional description The reverse rinsable filters hold back any dirt particles in the water. These particles are then completely flushed out by reverse rinsing. Filters with Double Spin Technology have turbine blades which circulate the water and thereby set the rotor on the upper filter into a rotational motion. The internal impeller rinses off particles that have adhered to the upper filter at the intersecting points with the rotor. The filter combinations (FK76CS and FKN76CS) combine reverse rinsing filter and pressure reducing valve in one appliance. 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.

Maximum 16.0 bar with clear filter bowl

• Install in horizontal or vertical pipework with filter bowl downwards o This position ensures optimum filter efficiency • Install shutoff valves • Ensure good access o Pressure gauge can be read off easily o Degree of contamination can be seen with clear filter bowl o Simplifies maintenance and inspection • Fit immediately after water meter o Corresponds to DIN 1988, Part 2 • The installation location should be protected against frost

F76CS/FN76CS: Operating pressure Maximum 16.0 bar The filter is constructed for drinking water installations. In case of a process water application the filter has to be proven individually.

1. Thoroughly flush pipework 2. Install rotatable connector piece o Note flow direction o Install without tension or bending stresses When connecting to an existing flange of another make ensure that the inlet flow is through the outer ring of holes. If this is not so, the whole connection piece must be installed the other way round, even if the arrow does not then indicate the actual flow direction. If the flange is threaded, the threaded holes must be drilled out to a diameter of 6.3 mm. 3. Install filter to rotatable connector 4. Seal in pressure gauge

During reverse rinsing, an inlet pressure of at least 1.5 bar is required. The reverse rinsing interval depends on the degree of dirt in the water. At the latest every 2 months, reverse rinsing should be carried out according to DIN 1988, Part 8. To ensure convenient and regular adherence to the reverse rinsing interval, we recommend installing an automated reverse rinsing system Z11S. Filtered water can also be tapped during reverse rinsing.

8.2.1 Manual reverse rinsing If reverse rinsing water is not to be discharged via a direct connection, a collecting container must be positioned beneath before reverse rinsing. 1. Open ball valve by turning the reverse rinsing button to the stop point o Select bar must be upright o The patented reverse rinsing system starts o When filtering with Double Spin Technology, a visual function check is possible through the rotating red rotor 2. Close ball valve again after approx. 3 seconds. Repeat procedure three times o If the filter is extremely dirty, the procedure may have to be repeated additional times With aid of the memory ring, the next deadline for manual reverse rinsing can be booked.

7.3 Discharge of reverse rinsing water The reverse rinsing water must be routed to the drain channel in such a way that no backwater can occur. To do this there are 3 options: 1. Direct connection: o Connector DN 50/70 as well as the necessary pipes and siphon (3 elbows 90°) in DN 70. 2. Drain free to existing floor drain. 3. Drain into open container. Filter size

8.2.2 Automatic reverse rinsing with the Z11S

*at 4 bar inlet pressure and 3 x 3 seconds reverse rinsing duration

The automated reverse rinsing system Z11S is available as an accessory. The automated system reliably takes over reverse rinsing of the filter at intervals which can be set between 4 minutes and 3 months.

8. Commissioning 8.1 Setting outlet pressure (only FK76CS/ FKN76CS)

Set outlet pressure min. 1 bar under inlet pressure. 1. 2. 3. 4. 5.

We recommend a planned maintenance contract with an installation company

Close shutoff valve on inlet Release pressure on outlet side (e.g. through water tap) Close shutoff valve on outlet Loosen slotted screw o Do not remove slotted screw Slacken tension in compression spring o Turn control handle to the left (-) until it does not move any more Slowly open shutoff valve on inlet Turn control handle until the setting scale shows the desired value Retighten slotted screw Slowly open shutoff valve on outlet

In accordance with DIN 1988, part 8, the following measures must be taken:

9.1 Inspection 9.1.1 Pressure reducing valve(only FK76CS/ FKN76CS) Interval: once a year 1. Close shut off valve on outlet 2. Check back pressure using a pressure meter when there is zero through-flow o If the pressure is increasing slowly, the valve may be dirty or defective. In this instance, carry out servicing and cleaning 3. Slowly open shutoff valve on outlet

Honeywell GmbH GB 9.1.2 Filter

2. Release pressure on outlet side (e.g. through water tap) 3. Close shutoff valve on outlet 4. Loosen slotted screw o Do not remove slotted screw 5. Slowly open shutoff valve on inlet 6. Set desired outlet pressure (e.g. 4 bar) 7. Align scale (e.g. 4) in middle of viewing window 8. Retighten slotted screw 9. Slowly open shutoff valve on outlet

Interval: every 2 months • The filter must be cleaned by reverse rinsing regularly, at the latest every 2 months • Non-compliance can lead to the filter becoming blocked This results in a drop in pressure and decreasing water flow • The filter meshes are made of stainless steel. A red coating as a consequence of rust from the pipelines has no influence on function or the way the filter works Do not forget to do a visual check of the ball valve. Replace if it is dripping!

9.3.1 Filter Interval: every 2 months • The filter must be cleaned by reverse rinsing regularly, at the latest every 2 months • Non-compliance can lead to the filter becoming blocked This results in a drop in pressure and decreasing water flow • The filter meshes are made of stainless steel. A red coating as a consequence of rust from the pipelines has no influence on function or the way the filter works Do not forget to do a visual check of the ball valve. Replace if it is dripping!

9.2 Servicing 9.2.1 Pressure reducing valve(only FK76CS/ FKN76CS) Frequency: every 1-3 years (depending on local operating conditions) To be carried out by an installation company 1. 2. 3. 4.

Close shutoff valve on inlet Release pressure on outlet side (e.g. through water tap) Close shutoff valve on outlet Loosen slotted screw o Do not remove slotted screw Caution ! There is a spring in the spring bonnet. It may cause injuries if the spring is derailing. • Make sure tension in compression spring is slakkened! 5.

11. Troubleshooting 11.1 FK76CS/FKN76CS Problem Cause Water is escaping from the spring Diaphragm in valve insert is faulty bonnet Too little or no water pressure Shutoff valves upstream or downstream from filter not fully open Pressure reducing valve is not set to the desired outlet pressure Filter mesh dirty Not fitted in flow direction The outlet pressure set does not remain constant

Remedy Replace valve insert Open the shutoff valves fully Set outlet pressure Reverse rinsing Fit filter in flow direction (note direction of arrow on housing) Reverse rinsing Replace valve insert

Filter mesh dirty Valve insert, sealing ring or edge of nozzle is contaminated or worn Rising pressure on outlet (e.g. in boiler) Check check valve, safety group etc.
