The choice and installation of the system components is
delegated to the installer, who will have to operate accord-
ing to the rules of good technique and current legislation.
9
The discharge of the installed safety valves must be con-
nected to an adequate collection and evacuation system.
The manufacturer of the appliance is not responsible for any
flooding caused by the intervention of the safety valves.
9
Is suggested to put a by-pass connection for the heat pump
in order to allows the cleaning of the system pipes without
disconnecting the unit.
9
The connection tubes must have the appropriate diameter
and must be supported, so as not to rest their weight on
the unit.
9
The systems with anti freeze additives or specific local laws,
require the installation of hydraulic backflow preventers.
9
Check the pressure drops of the appliance, the system, and
any other accessories mounted in line.
9
Do not use the heat pump for treating industrial water,
swimming pool water or domestic water. If water supplies of
this kind are used, an intermediate heat exchanger must be
used. Make sure to maintain the min. water content, possi-
bly adding a storage.
9
If the unit works in a system with a boiler >(parallel instal-
lation) when the boiler is working, make sure that the water
temperature inside the heat pump does not exceed 60 °C.
Mandatory items:
— install a removable mesh water filter at the inlet to the ap-
pliance in an area accessible to maintenance, with char-
acteristics of at least 10 meshes / inch², to protect the ap-
pliance from impurities in the water
— after the installation of the system and after each repair, it
is essential to clean the entire system thoroughly, paying
particular attention to the condition of the filter
— install a suitably sized expansion vessel
— install air vent valves in the highest points of the pipes
— install air vent valves in the highest points of the pipes
— ensure that the quantity of water in the primary circuit is
greater than the minimum volume indicated in the chap-
ter "Plant water content"
p. 17, ensure that the quantity
of water in the primary circuit is greater than the minimum
volume indicated in the chapter
— Foresee the pipes insulation, after the leackage verifica-
tion, in order to minimize the heat loss and the conden-
sate effect.
— Use anti freeze additives in order to prevent the wter freez-
ing if the water circuit and pipes are exposed to ambient
temperature below 0°C.

It is forbidden to run the unit without a clean water filter
installed.
