Assembly

3.1 Installation Guidelines

• Horizontal and vertical installation position possible
  – In vertical installation position spring bonnet with adjustment knob facing upwards

• Install shut-off valves

• The installation location should be protected against frost and be easily accessible
  – Pressure gauge can be read off easily
  – Simplified maintenance and cleaning

• To guarantee perfect functioning, a filter must be inserted ahead of the pressure reducing valve

• Provide a straight section of pipework of at least five times the nominal valve size after the pressure reducing valve (in accordance with EN 806-2)

• Requires regular maintenance in accordance with EN 806-5

3.2 Assembly instructions
CAUTION!
When using soldering connections, do not solder the connections together with the pressure reducing valve! High temperature will irreparably damage important internal working components!

1. Thoroughly flush pipework

2. Install pressure reducing valve
   • Note flow direction
   • Install without tension or bending stresses

3. Set outlet pressure

The green adjustment knob must stay plugged on to prevent dirt from entering.

Start-up

4.1 Setting outlet pressure
Set outlet pressure min. 1 bar under inlet pressure.

1. Close shut-off valve on inlet

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

3. Fit manometer (standard version)

4. Close shut-off valve on outlet

5. Fit adjustment knob

6. Slacken tension in compression spring
   • Turn adjustment handle counter clockwise (-) until it does not move any more

7. Slowly open shut-off valve on inlet

8. Turn adjuster knob until the manometer shows the desired value

9. Slowly open shut-off valve on outlet

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:

5.1 Inspection

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 5.2 Maintenance)

3. Slowly open shut-off valve on outlet

5.2 Maintenance
Do not use any cleansers that contain solvents and/or alcohol for cleaning the plastic parts, because this can cause damage to the plastic components – water damage could result.
Detergents must not be allowed to enter the environment or the sewerage system!

1. Close shut-off valve on inlet

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

3. Close shut-off valve on outlet

4. Fit adjustment knob
   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 slackened!

5. Slacken tension in compression spring
   • Turn adjustment handle counter clockwise (-) until it does not move any more

6. Unscrew spring bonnet

7. Remove valve insert with a pair of pliers

8. Remove filter and clean

9. Check that sealing ring, edge of nozzle and ’o’-ring are in good condition, and if necessary replace the entire valve insert

10. Reassemble in reverse order
    Press in diaphragm with finger before inserting slip ring

11. Set outlet pressure

Disposal

Observe the local requirements regarding correct waste recycling/disposal!

Troubleshooting

Customer Services
Water is escaping from the spring bonnet| Diaphragm in valve insert is faulty| Replace valve insert
Too little or no water pressure| Shut-off valves up- or downstream of the pressure reducing valve are not fully open| Open the shut-off valves fully
Pressure reducing valve is not set to the desired outlet pressure| Set outlet pressure
Filter in pressure reducing valve is contaminated| Clean or replace filter
Pressure reducing valve is not fitted in flow direction| Fit pressure reducing valve in flow direction (note direction of arrow on housing)
The outlet pressure set does not remain constant| Filter in pressure reducing valve is contaminated or worn| Clean or replace filter
Valve insert, sealing ring or edge of nozzle is contaminated or worn| Replace valve insert
Rising pressure on outlet (e.g. in boiler)| Check check valve, safety group etc.
