Specifications

Liquid category backflow preventer BA: 4 (toxic, highly toxic, tumourigenic, radioactive materials)Installation position:

horizontal pipework with discharge connection directed downwardsSuitable for heating systems with the following materials: aluminium, aluminium alloys,steel, copper, copper alloys and plastics.Treated water has modified corrosive chemicalparameters. Conditioning by means of inhibitors is to be provided for separately.

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

Assembly

It is necessary during installation to follow the installation instructions, comply with local requirements, and follow the codes of good practice.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 a height of at least 610 mm from the ground to ensure that cartridges can be replaced
Downstream of the refilling combination (VE300S), provide a 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 vapors 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 headwater 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

Assembly instructionsTo 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)

Thoroughly flush pipework
Install the refilling combination (see NK300S)
Install in horizontal pipework with discharge connection directed downwards• Note flow direction (indicated by arrow)• Install in horizontal pipework with discharge connection directed downwards• Installation height should be min. 55cm from the floor in order to warrant the safe replacement of the cartridge
Attach drain pipe to discharge connection (plastic pipe HT 50)
Install heater water treatment unit (VE300S) directly below the refilling combination (NK300S) and secure in place with the wall bracket• Install in a horizontal pipeline• Note flow direction (indicated by arrow)• Install without tension or bending stresses
Screw the complete demineralization cartridge (P300LES) into the heater water treatment unit (VE300) and tighten by hand.

Start-up

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

Adjust the back pressure (see NK300S)
Set to complete demineralization (see VE300S)
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:

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

Pressure reducing valve function control (see NK300S)
Drain valve function control (see NK300S)

MaintenanceDo not use any cleaners 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 the scope of delivery)

Valve insert and screen (see NK300S)
Maintenance and cleaning of cartridge insert (see NK300S)
Check valve (see NK300S)
Replacement of the complete demineralization cartridge (see VE300S)

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

Disposal

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