Hydraulic installation of the heating and DHW circuit.
The hydraulic installation should be carried out by qualified personnel, in compliance with the
current installation regulation (RITE) and considering the following recommendations:
- The inside of the installation piping should be thoroughly cleaned before switching on the
boiler.
- We recommend inserting cut-off valves between the installation piping and the appliance to
simplify maintenance tasks.
- If the module is installed at a lower height than the heating installation, it is advisable to create
a siphon at the boiler outlet, to prevent the installation from heating up due to natural
convection when heating is not required.
- When the DHW supply pressure is over 0.7 MPa (7 bar), a pressure reducer must be fitted.
- It is advisable to install a thermostatic mixing valve at the DHW outlet to protect against burns
and to guarantee a constant, stable supply of hot water.
-
The condensation pipe must lead to a drain outlet
, as the
Fusion Hybrid Gas Condens
module is a gas condensation module, and a large amount of water may be generated. In
addition, before starting up the boiler, it is advisable to fill the condensation outlet siphon tube
with water, so that the flue gases do not exit through this tube.
- All water circuit piping
MUST
be insulated to prevent condensation during operation in
cooling mode and reduction of cooling and heating capacity, as well as to prevent freezing of
outside pipes during winter. The minimum insulation thickness of the pipes should be 19 mm
(0.039 W/mK), preferably comprising a closed cell insulation or a vapor barrier. In outdoor areas
exposed to the sun, the insulation must be protected from the effects of degradation.
- Drain valves and suitable devices should be fitted for the correct removal of air from the circuit
during the filling stage.
- A water filter
must be installed
in the water circuit of the heat pump, in order to avoid
obstructions or narrowing caused by dirt in the installation. The filter
MUST
be installed before
filling the installation with water and in the return branch of the machine, in order to avoid the
entry of dirty water into the heat exchanger (condenser). It is advisable to insert this filter
between two cutting keys, in order to avoid emptying the installation during cleaning. The
type of filter installed must be adapted to the particular characteristics of each installation
(type and material of the water pipes, type of water used, water volume of the installation, etc.).
The water filter should be checked and cleaned, if necessary, at least once a year. In new
installations, however, it is advisable to check it within the first few months of its
commissioning.
- The
Fusion Hybrid Gas Condens
hydraulic module is an accessory that should be installed in
combination with a
DUAL CLIMA
heat pump for its correct operation. Therefore, in addition to
the recommendations described above, it must comply with those indicated in the heat pump
installation manual.
For the correct operation of the heat pump, it is essential to install a filter in the
return line of the heat pump. This filter is included in the documentation bag of the
Fusion Hybrid Oil module.
