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
Fig. 1: Functional principle
[1] Filter cartridge
[2] Removable sheath to easily clean the magnet
[3] Filter chamber
[4] Magnet
[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

5. Installation
For the installation no special tools are required.
Standard heat and sanitary installer's tools are
sufficient.
5.1 Torque specification
Fig. 5: Torque specification
Tab. 6: Torque specification for fasteners
5.2 Checking scope of delivery
Tab. 7: Scope of delivery
• Check delivery for completeness and integrity.
• Unpack all parts.
• Inform Honeywell Technical Team if parts of the
delivery are damaged or missing.
• Never install damaged parts.
5.3 Installation Guidelines
The installation site has to be frost-proof and the
protection of the device from chemicals, paints,
detergents, solvents and their vapors and
environmental influences must be guaranteed.
• Install if possible in horizontal or vertical pipe work
with filter housing downwards
- This position ensures optimum filter efficiency
• Ensure good access
- Simplifies maintenance and inspection
5.4 Installation
• Read these installation instructions completely
before beginning the installation.
• Make certain that the heating system is standing idle
properly (see manufacturer's instructions for the
heating system).
• Drain heating system and locate return pipe. Filter is
typically installed in the return pipe.
Mark the section to be cut out according to the
cutting ruler and remove the marked pipe section.
• Mark the length of the pipe section to be removed
using the cutting ruler on the edge of the packaging
sleeve at hand.
• Make sure there is adequate room to rotate the filter
and access it for cleaning purposes.
