Filling the installation
The FUSION hydraulic module has a filling disconnector and a manometer, by means of which the
water filling of the complete Heating/Cooling system can be carried out, including the external unit
and the exchanger of the DHW cylinder. In turn, the hydraulic installation should incorporate the
drain valves and hydraulic components necessary for its correct filling.
To carry out the filling, open the disconnector valves until the
manometer indicates a pressure between 1 and 1.5 bar. The heat
pump (external unit) includes a manual drain valve on the upper
part of the heat exchanger flow tube (condenser). Open it during
the filling process and wait for the water to start running (please
refer to the operations manual of the
DUAL CLIMA
heat pump). The
air should also be bled from the rest of the installation using the air
bleed valves provided. The filling must be carried out slowly,
thereby facilitating air evacuation from the water circuit. Once the
installation is full, close the disconnector valves.
IMPORTANT: Starting the heat pump without water may cause serious damage to it.

Drainage
The
FUSION
hydraulic module has 2 drain valves: one to drain the
water from the primary installation and the other to drain the
Domestic Water from the inside of the tank. For the correct drainage
of any of the two circuits, a flexible tube should be connected to the
corresponding tube and led to a drain. In the case of the drainage of
the primary installation, it is advisable to open the steam traps
present in the heating/air conditioning system so that air enters the
circuit once the pressure in the circuit has been lost. After draining
the boiler, close the valve again and remove the flexible tube.

OPERATION
The
FUSION
hydraulic module is a passive accessory. Therefore, its operation will be fully managed by
the
DUAL CLIMA
heat pump controllers connected to it, which should be mounted on the front of the
module (see
“Assembly and connection of the control panel”
). To properly configure and manage its
operation, please carefully read the “Installation and Operating Instructions Manual” supplied
alongside the heat pump.
Nevertheless, in order to obtain all the features for which the all-in-one hydraulic module has been
provided, it should be ensured at least that the DHW service and the Heating and/or Cooling service
are activated by adjusting the DIP-Switch (
SW1
) of the control panel of the heat pump.
