Installation Guidelines

• Install shut-off valves before and after backflow preventer
• Install backflow preventer downstream of the filter or strainer ­ This protects the appliance against dirt
• Install in horizontal pipework with the discharge valve downwards
• Ensure skillful access ­ Simplifies maintenance and inspection
• In order to avoid flooding, information technology is recommended to arrange a permanent, professionally dimensioned wastewater connectedness
• The installation environment should be protected against frost and ventilated well
• Install discharge pipework which has acceptable capacity
• These armatures need to be maintained regularly

Associates in  structions

1. Thoroughly flush pipework
2. Ensure that connections on back flow preventer are make clean
3. Install backflow preventer
4. Install in horizontal pipework with discharge connection directed down
   ● Notation menstruation management (indicated by arrow)
   ● Install without tension or bending stresses
5. Provide a straight section of pipework of at to the lowest degree five times the nominal valve size after the backflow preventer
6. Maintain assembly distances
7. Load the middle screw only in axial direction
8. Connect discharge pipework close coupled and without tight bends according to connexion dimensions (see tabular array)
9. Install discharge pipework in such a way that the belch connection and the discharge valve can exist removed for inspection

Maintenance

In order to comply with EN 806-five, water fixtures must be inspected and serviced on an almanac basis. Equally all maintenance work must exist carried out by an installation visitor, information technology is recommended that a servicing contract should be taken out.
In accordance with EN 806-five, the following measures must be taken:

Inspection

The inspection should also include ancillary equipment such as strainers and shut-off valves.

Testing inlet check valve

Take note of the instructions of the test control unit TKA295

1. Procedure according to instruction of the test control unit TKA295

Testing discharge valve

Take note of the instructions of the test control unit TKA295

1. Procedure according to instruction of the examination control unit TKA295
   Quick test for the belch valve:

• Lower the inlet pressure ­
  – if the belch valve opens (it drops), the function is o.chiliad.

Testing outlet check valve

Take note of the instructions of the test command unit of measurement TKA295

1. Procedure according to instruction of the examination command unit TKA295

Maintenance

Do not use whatsoever cleansers that contain solvents and/or alcohol for cleaning the plastic parts, considering this can cause damage to the plastic components – water damage could issue.
Detergents must not be immune to enter the environment or the sewerage system!

Discharge valve

1. Close shut-off valve on inlet
2. Close close off valve on outlet
3. Release force per unit area using the 3 ball valves
4. Unscrew pressure level command line
5. Open screws on the chapeau
6. Remove cover
7. Push clench together and remove
8. Remove discharge valve upwards
   ● Clean or replace equally required
9. Grease O-rings for drinking water installation well with admissible greasing agent, supplant damaged O-rings
10. Reassemble in reverse gild
11. Exam function (see 5.i Inspection)

Check valve

1. Close shut-off valve on inlet
2. Close shut-off valve on outlet
3. Release pressure using the three brawl valves
4. Open screws on the lid
5. Remove cover
6. Push button clamp together and remove
7. Twist securing ring out of the receiving slot
   Circumspection!
   ! Adventure of injury – Cheque valves are under spring tension!
8. Pull out the check valve
   ● disassemble the outlet check valve first, and the inlet check valve
   ● Make clean or replace as required
   ● Leaking check valves must exist replaced.
   ● If the edge seals are worn, you can switch the cases of the 2 check valves with each other (see conversion check valves)
9. Reassemble in reverse society
   ● Grease the O-ring on the check valve with greasing agent admissible for drinking water
   ● Exercise not harm `O' ring during associates
   ● Securing band Pos. seven (moving-picture show five.2.ii.) that the opening is facing down
10. Test function (see v.i Inspection)

Conversion check valves

Caution!
Take a chance of injury – Cheque valves are under spring tension!

1. Detach both bank check valves by loosening the hexagon bolt
2. Assemble the housing of the inlet cheque valve with the components of the outlet backflow preventer
3. Assemble the housing of the outlet bank check valve with the components of the inlet check valve

Disposal

Troubleshooting

Problem	Cause	Remedy
Belch valve opens without credible reason	Pressure strokes in h2o supply system	Install a pressure reducing valve upstream the backflow preventer
	Fluctuating inlet pressure	Install a pressure reducing valve upstream the backflow preventer
	Inlet bank check valve and/or belch valves are dingy	Remove check valve or discharge valve and clean it
	Leaky inlet check valve	Supervene upon check valve
Discharge valve don't close	Deposits on valve seat	Remove discharge valve, clean or supplant it
	Damaged 'o'ring	Remove belch valve and replace 'o'band
	Leaky discharge valve	Remove discharge valve, make clean or supercede information technology
Belch valve don't open	Blocked force per unit area control pipe	Remove control pipage and make clean it
