* 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.

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