Preliminary warnings
The engineer is responsible for choosing the right water
lines and their size, in accordance with good installation
practices and the applicable law.
The hydraulic system is made by the installer and must be
carried out with reference to the diagrams in this manual
or on the website.
The hydraulic pipes connecting to the appliance must be
suitably sized for the actual water flow rate required by the
plant during operation. The water flow rate to the heat ex-
changer must always be constant.
The maximum permissible pressure drops must be
compared with the data shown in chapter "Pressure
drop" p. 38. If higher heads are required due to high
pressure drops in the plant, an external pump with respec-
tive buffer vessel must be used.
Make sure that the quantity of water in the primary circuit
is greater than the minimum volume indicated in chapter
"Plant water content and minimum flow rate" p. 21, to

Make sure that:
• it is levelled
• easy access is allowed to the hydraulic and electrical parts
prevent the risk of ice formation during defrosting oper-
ations or continuous modulation of the compressor fre-
quency
It is important to note that the heat pump Control Panel
manages all the adjustments of the primary circuit (plant
and domestic hot water set-point, circulation pump, dy-
namic set control and auxiliary heater management).
Any regulation that foresees the management of the plant
with a control unit or a boiler conflicting with these regu-
lations must be submitted to the manufacturer's technical
office in advance for approval otherwise the warranty will
be invalidated.
If the appliance is connected in parallel with a boiler, make
sure that the temperature of the water circulating in the
heat pump does not exceed 60 °C during operation.
