HYDRAULIC CIRCUIT INSIDE 22.1.
THE VXT HEAT PUMP
The heat pump is destined to connection
with a closed air-conditioning plant and
a domestic hot water production circuit.
To guarantee correct functioning,
the plant must have been set-up by
authorised technicians in compliance
with the provisions in force on the
subject.
NOTE
The presence of filters is TO BE
CONSIDERED MANDATORY, REMOVAL
MAKES THE WARRANTY VOID. They
must be kept clean. It is therefore
necessary to check cleanliness after
installation of the unit and to periodically
check their state.
VXT external hydraulic circuit
(components not supplied)
The choice and installation of
components outside the VXT is up
to the installer, who must operate
according to the rules of good practice
and in compliance with the regulations
in force in the country of destination
(Ministerial Decree 329/2004).
HEATING CIRCUIT 22.2.
REQUISITES
For installation of the heating system
the EN 12828 Standard prescribes
the inclusion of certain components
of planting, some of them have already
mounted inside the unit:
An expansion vessel with membrane −
in the return pipe of the heating
system
All of the exchangers are equipped −
with pressure differential and
mechanical filter input
Flow switch positioned in the output −
DHW circuit
Mechanical filter input to the DHW −
circuit
A filling manual valve that allows −
to fill and drain the water from the
heating system
In addition, the following are −
necessary components of plant not
supplied:
A safety valve against over- −
pressures (opening pressure 3
bar)
Manometer (safety unit) in the −
heating circuit flow pipe, directly
behind the appliance
A separator of air and dirt in the −
heating circuit return pipe.
To prevent heat loss and to prevent −
freezing insulate all connection
pipes as prescribed by the decree
relative to energy saving.
The piping must be clean; if −
necessary, rinse it carefully before
filling.
The installation of the following is
recommended:
Anti-vibration joints −
Shut-off cocks −
Safety valve (if not supplied with the −
machine)
Manometers −
