GB Description of device
3. Description of device
The MHF49 is used to filter out contaminants
(e.g. sludge, sand, rust, iron particles etc.) that arise
from the regular operation of a heating system. Thus,
premature wear and failure of the heating system
arrising from contaminants can be prevented.
3.1 Product features
• Removes sludge and impurities
• Improved hydraulic performance
• Suitable for any installation position
• Protects the boiler
• Extends the service life of the heating system
• Guarantees system efficiency
• Can be used to top up Water Treatment (0.5 liters)
• Isolation valves
3.2 Functional principle

[5] Dirty medium
[6] Cleaned medium
Through a specifically designed path the medium is
forced to pass within the filter cartridge mesh and into
the filter chamber. There a combined actions of
the filter mesh, magnet and inner geometry of the Filter
chamber, allow heavy particles to sink to the bottom,
while the magnet inside the filter captures any rust and
iron particles
In that way impurities (eg. sludge, sand, rust, iron
particles) normally found in a central heating system
can be easily removed and kept inside the filter
chamber.
The cartridge is specifically designed to keep the
pressure drop low (it exercises low hydraulic
resistance) giving a particular path to the medium
which contributes to dragging heavy impurities to the
bottom of the filter. During maintenance, in order to
easily clean the magnet housing, remove the sheath
and clean it.
In the first instance, the boiler is protected against
damage from impurities. The MHF49 is most effective
when it is installed at these positions in the heating
circuit:
• In the return flow downstream of the last radiator but
upstream of the circulation pump
• Especially at start-up to protect the boiler/buffer by
removing medium-sized impurities (mainly sludge
and iron particles)
• All (vertical, horizontal) positions are possible for
installation
3.3 Accessory (optional)
• MHF49-IS Insulation shell
