3.2
Hydraulic installation
The hydraulic installation should be carried out by qualified personnel, in compliance with the current
installation regulation and considering the following recommendations:
•
For the hydraulic connection between the
FUSION
module and the
DUAL CLIMA
heat
pump, use two conveniently insulated tubes to connect the
IBC
and
RBC
sockets of the
module (see
“Diagrams and Measurements”
) with the flow and return sockets of the heat
pump, respectively.
•
All water circuit piping
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
filte
r 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 prior
to filling the installation and on the return branch of the machine with water, to avoid the
entry of dirty water into the heat exchanger (condenser).
It is recommended to insert
this filter between two cut-off valves, in order to be able to clean it without
emptying the installation
. 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,
volume of water in the installation, etc.). The water filter should be checked and cleaned, if
necessary, at least once a year, although in new installations it is recommended to check it
in the first months after commissioning.
The
FUSION COMBI
hydraulic module is an accessory that should be installed in combination with a
DUAL CLIMA R
and an existing boiler 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.
ATTENTION: The DUAL CLIMA R heat pump incorporates a 2-liter expansion tank as
standard. Due to the total amount of water in the heating / air conditioning
installation, if necessary, this capacity should be increased by installing
another supplementary expansion vessel.
ATTENTION: A pipe with a diameter suitable for the installation must be used so that the
minimum flow is reached in the hydraulic circuit.
ATTENTION: Before connecting the heat pump, a thorough internal cleaning of the pipes
of the hydraulic installation must be carried out.
