Treated water has modified corrosive chemical parameters. Conditioning by means of inhibitors is to be provided for separately.

* In order to estimate the capacity of the cartridge for fresh water hardness > 26°dH/46,4 °fH/4.64 mmol/l a manual calculation method has to be used. (see Installation Manual of the P300 cartridges incl. in the packaging of the cartridges)

Assembly

It is necessary during installation to follow the installation instructions, to comply with local requirements and to follow the codes of good practice.

3.1 Installation Guidelines

• Installation in the inlet to the heating system, fasten the refilling combination (VE300S) to the wall
• Install in horizontal pipework with discharge connection respectively cartridge connection directed downwards
• Install at height of at least 610 mm from the ground to ensure that cartridges can be replaced
• Downstream of the refilling combination (VE300S), provide settling section of at least 500 mm before integration in the heating circuit
• The installation may not take place in areas or ducts where poisonous gases or vapours may be present or where flooding can occur
• The installation environment should be protected against frost and ventilated well
• The installation location has to be easily accessible: Simplified maintenance and cleaning, Pressure gauge at the pressure reducing valve can be read off easily
• According to EN 1717 in direction of flow, first install the heatwater treatment unit (NK300S) and directly after it, the refill combination (VE300S)
• The national installation regulations must be observed during the assembly
• Requires regular maintenance in accordance with EN 806-5
• In order to avoid flooding, it is recommended to arrange a permanent, professionally dimensioned wastewater connection

3.2 Assembly instructions

To avoid stagnating water the refilling combination (NK300S) must be attached as directly as possible to the service pipe!

The national installation regulations apply during the assembly.

• Only fasten the plastic sealing plugs by hand (without tools)

Start-up

For information on start-up, see the instructions of the individual components (included in scope of delivery)

1. Adjust the back pressure (see NK300S)
2. Set to complete demineralisation (see VE300S)
3. Fill the system (see VE300S)

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

For information on inspections, see the instructions of the individual components (included in scope of delivery)

1. Pressure reducing valve function control (see NK300S)
2. Drain valve function control (see NK300S)

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!

For information on maintenance, please refer to the instructions of the individual components (included in scope of delivery)

1. Valve insert and screen (see NK300S)
2. Maintenance and cleaning of cartridge insert (see NK300S)
3. Check valve (see NK300S)
4. Replacement of the complete demineralisation cartridge (see VE300S)

To determine the maximum capacity of the complete demineralisation cartridge, see instruction P300L

6 Disposal

For information on malfunctions / trouble shooting, please refer to the instructions of the individual components (included in scope of delivery)! Observe the local requirements regarding correct waste recycling/disposal!

7 Troubleshooting

For information on malfunctions / trouble shooting, please refer to the instructions of the individual components (included in scope of delivery)
