Safety note
The
magnetic
®
NF plus
should be flushed with about 10 litres of water before each use to get rid of the first amount of
water flow through the device. A permanent connection with a heating system filling hose is not permitted. Unsupervised
use is not permitted.
The fresh water tap, the shut-off valves on the
magnetic
®
NF plus
and the boiler shut-off valve must always be closed and
the filling hose must always be removed after each use.
The mixed bed resin in the container must not get into the heating system. A fine-meshed strainer is integrated into the
outlet for safety reasons – it must not be removed.
1. Flushing the tank
2. Refill the heating system
3. Close tap/valves, remove hoses
The function
The
magnetic
®
NF plus
removes limescale and aggressive water constituents, like sulphates, nitrates and chlorides, from the
filling water. The device works on the basis of a mixed-bed-resin ion exchanger and delivers demineralised water quality for
every heating system size. This method does not add any chemicals to the water. The device works without external electrici
-
ty connection.
Use with heating system filling hose
The
magnetic
®
NF plus
device must be pre-flushed with fresh drinking water if it is occasionally used for topping-up the heating
system with a hose in order to get rid of the first amount of water flow through the device. That is done by checking the demi
-
neralisation with the integrated measuring computer. The filling hose must be vented before the subsequent filling process, i.e.
filled with water to prevent any air from the filling tap getting into the heating system.
