Assembly

Installation Guidelines

• 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 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

Assembly instructions

1. Thoroughly flush pipework

2. Install rotatable connector piece
   • Note flow direction
   • Install without tension or bending stresses
   CAUTION!
   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.

3. Install filter with sealing to rotatable connector

4. Tighten the connecting nuts (7Nm)

5. Screw-in discharge connection

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:

• Direct connection:
• Connector DN 50/70 as well as the necessary pipes and siphon (3 elbows 90°) in DN 70.
• Discharge into floor drain
• Drain into the open container.

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

Start-up

Setting outlet pressure (FK74CS/ FKN74CS only)

Set outlet pressure min. 1 bar under inlet pressure.

1. Close shut-off valve on the inlet

2. Release pressure on the outlet side (e.g. through water tap)

3. Close shut-off valve on outlet
   Connection sizes 1 ¹/2″ – 1 /4″
   Slacken tension in compression spring
   3.1)Lift adjustment handle
   3.2)Turn adjustment handle counterclockwise (-) until
   it does not move anymore

4. Connection sizes 1 ¹/2″ – 2″
   Slacken tension in compression spring
   4.1)Loosen the slotted screw
   Do not remove the slotted screw
   4.2)Turn adjustment handle counterclockwise (-) until
   it does not move anymore

5. Slowly open the shut-off valve on the inlet

6. Turn the adjuster knob until the manometer shows the
   desired value
   • Turn clockwise = increase pressure on the outlet side
   • Turn counter-clockwise = reduce pressure on the outlet side

7. Connection sizes 1 ¹/2″ – 1 /4″
   7.1)Push the adjuster knob down and latch it in to activate the locking mechanism
   Connection sizes 1 ¹/2″ – 2″
   7.2)Fasten the slotted screw to lock the mechanism

8. Slowly open shut-off valve on the outlet

Reverse rinsing

During reverse rinsing, an inlet pressure of at least 1.5 bar is required.
The filter must be cleaned by reverse rinsing at the latest every 6 months! (According to EN 806-5.) Producer recommendation at least every 2 months!
To ensure convenient and regular adherence to the reverse rinsing interval, we recommend installing an automated reverse rinsing system.
(Connection sizes:
1 ¹/2″ – 1/4″ Z74A
1 ¹/2″ – 2″ Z11S-A

CAUTION!
Filtered water can also be tapped during 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 handle to the stop
   • Handle must be upright
   • The patented reverse rinsing system starts

2. Close ball valve again after approx. 3 seconds.
   Repeat procedure three times
   • 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.

Maintenance

In order to comply with EN 806-5, water fixtures must be inspected and serviced on an annual basis.
As all maintenance work must be carried out by an installation company, it is recommended that a servicing contract should be taken out.
In accordance with EN 806-5, the following measures must be taken:

Inspection

Pressure reducing valve (FK74CS/ FKN74CS only)

1. Close shut-off valve on outlet

2. Check outlet pressure using a pressure meter when there is zero through-flow
   • If the pressure is increasing slowly, the valve may be dirty or defective. In this instance, carry out servicing and cleaning (See 6.2 Maintenance)

3. Slowly open shut-off valve on outlet

Filter

• The filter must be cleaned by reverse rinsing at the latest every 6 months! (According to EN 806-5.)
  Producer recommendation at least every 2 months!

• Non-compliance can lead to the filter becoming blocked This results in a drop in pressure and decreased 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 the visual check of the ball valve. Exchange the KF11SB filter bowl in case of drop
  formation!

(Connection sizes:
1 ¹/2″ – 1 /4″ KF11SB-1A
1 ¹/2″ – 2″ KF11SB-2A)

Maintenance
If necessary, the outside surface of the filter combination can be cleaned.
Use only cold, clean drinking water to clean the surfaces! Any other cleansers cause damage to the plastic components!

Pressure reducing valve (FK74CS/ FKN74CS only)

1. Close shut-off valve on the inlet

2. Release pressure on the outlet side (e.g. through water tap)

3. Close shut-off valve on the outlet
   CAUTION!
   There is a spring in the spring bonnet. It may cause
   injuries if the spring is derailing.

4. Connection sizes 1 ¹/2″ – 1 /4″
   Slacken tension in compression spring
   4.1)Lift adjustment handle
   4.2)Turn adjustment handle counterclockwise (-) until
