Some of the components in the diagram may already be
included in the unit with the hydronic kit. Those not included
must be provided by the installer.
Connection pipes must have a suitable diameter and be
supported so as not to impose their weight on the unit.
The units allow synergies to be created at plant level by offering
the possibility of recovering heat from industrial processes or to
be integrated with other technical systems that produce hot
water at medium temperature. Part of the energy produced can
be used as a heat source by the units to produce hot water at
high temperature.
4.1.1 Water filter
Water filters must always be installed on the machine inlet side.
Square mesh filters must be installed with:
- maximum side of 0,8 mm up to diameter DN80
- maximum side of 1,6 mm up to diameter DN150
The dimensions and the pressure drops must be adapted to the
installation.
Filters must be clean periodically.
