ASSEMBLY AND INSTALLATION
The DSPN Series dirt separator must be installed by
a qualified professional plumber.
WARNING: before carrying out any installation
or maintenance operation, make certain that the
automatic filling valve of the heating system (if
present) is shut off.
Install the DSPN dirt separator on the return leg of
the heating circuit, at the boiler inlet, to offer best
protection from all impurities in the system, especially
when the system is first started up.
Ensure that there is sufficient access available for the
purposes of repairs and maintenance.
WARNING: The DSPN dirt separator contains
powerful magnets. Always take maximum care during
installation and whenever maintenance operations are
carried out.
Do not place the magnetic core on ferrous surfaces.
WARNING: use appropriate protective devices during
all installation and maintenance procedures.
WARNING: to avoid damage from frost, avoid
installing the product in any location where
temperatures could drop below 0 °C.
The DSPN dirt separator can be installed in different
mounting positions:
- horizontal installation with cap facing forwards,
where there is limited space beneath the boiler (e.g.
boiler installed in a wall-mounted kitchen unit) (FIG. 4)
- vertical installation with cap facing downwards,
where there is more space available. (FIG. 5)
MAINTENANCE
CLEANING THE FILTER CARTRIDGE:
The filter cartridge can be cleaned periodically by
unscrewing the bottom drain plug or the top cap
incorporating the magnet holder.
When cleaning the DSPN dirt separator, make certain
that the boiler is switched off and that the separator
has cooled down to ambient temperature before
carrying out any maintenance operation, otherwise
damage and scalding could occur.
To ensure that the product stays intact and efficient
over time, routine maintenance, major servicing and
scheduled inspections must be carried out with
suitable care.
Proper maintenance involves the following steps:
- Close the ball valve on the inlet side.
- Unscrew the bottom drain plug carefully, and allow
the water to run off (fig. 1). If the filter is mounted
vertically, unscrew the cap with the magnet holder
directly, using the tool provided (fig. 2).
NOTE: collect the water drained from the filter in a
container of suitable proportions.
- Once the flow of water ceases, unscrew the closing
cap with magnet.
- Unscrew the magnet and take it out.
- Wash the cap with water to remove all impurities
completely.
- Check the state of the O-ring, and if worn or
degraded, fit a new one.
- Remove the mesh filter element and wash carefully
to remove any impurities trapped on the surface.
Refitting the dirt separator
- Screw the magnet onto the cap.
- Insert the metal filtering into the specific cap
housing.
- Screw the cap to the body anf tighten.
- Before returning the separator to normal operation,
open the feed valve slowly to check for leaks.
NOTE: the separator should be serviced and cleaned
at least twice a year.
NOTE: in the case of a new installation, perform the
first cleaning operation after one month.
WARNING: all routine maintenance and major
servicing operations must be carried out with the
separator isolated from the plumbing circuit.
Any operation carried out on the product must
be commenced only after reading the safety
requirements listed in this manual.
WARNING: the product is user-serviceable only for
the purpose of cleaning the filter element.
In the case of operations not described here, or
classifiable as major servicing, these can be carried
out only by skilled professionals.
NOTE: particular operating conditions (type of water,
operating pressure, etc.) may dictate the need for
more frequent maintenance.
NEODYMIUM MAGNETS
WARNINGS FOR APPROPRIATE USE
The neodymium magnets used in the FDM-1ME
appliance are contained inside a steel cylinder,
conveniently sealed to prevent the magnets
themselves from coming out. The magnetic cylinder
assembly can, however, be a potential source of
danger and the warnings below must be respected.
