MAGIS HERCULES PRO is the range of split inverter
air-water heat pumps with outdoor condensing unit and
indoor oor-standing unit, including a 235 litre domestic
hot water storage tank (single product, with single code for
indoor unit + condensing unit).
is is a heat pump-only solution line particularly suitable
for new residential homes (characterised by high thermal
insulation and integrated with a photovoltaic system), which
combines the advantages of having a domestic hot water
storage tank unit inside the same casing and the possibility
of managing air cooling/central heating systems up to 3 zones
(1 standard zone, zone 2 and zone 3 optional that can be
inserted in the casing); a 45 litre inertial storage tank is also
integrated into the indoor unit (which also acts as a hydraulic
manifold, which represents a further important advantage by
simplifying installation and optimising costs).
e range includes 9 versions, with powers of 4, 6, 9 kW
(single-phase) and 12, 14, 16 kW (both single-phase and
three-phase); the coolant used is R32 for machines up to 9
kW, R410A for machines from 12 kW and up.
e P.C.B. includes a system manager (standard), which
allows programming the generator functions directly from
the control panel; several temperature control devices are
available to control the temperature / humidity of the system
zones (optional for all zones).
In terms of electrical integration, the MAGIS HERCULES
PRO models are standard equipped with 2.3 kW DHW (Do-
mestic hot water) integrative resistance (possible combination
of 1 or 2 additional 2.3 kW DHW (Domestic hot water)
resistances – optional); it is also possible to combine the 3 kW
system integrative resistance (optional – only one or 2 can be
installed). Among the accessories, it is also possible to combine
a specic kit for connection to a solar thermal system.
At installation level, the oor standing indoor unit has an
IPX5D degree of protection (indoor installation only); on the
other hand, the condensing unit can be installed outdoors.
e water circuit is fully protected against freezing because
installed inside the home (there is no need to add antifreeze);
it is, therefore, also particularly suitable for cold climate areas.
Having to make the refrigerant connections between the
outdoor condensing unit and the oor standing indoor unit,
the F-GAS license is required for the connection.
MAGIS HERCULES PRO also meets the requirements of
the ErP Directive (2009/125/EC) and ELD (2010/30/EC);
there are a number of optional kits available, which allow it
to be used in dierent plant applications.

To simplify the work of the installers, this heat pump only system
was designed with particular attention to the how the product
is handled and transported to the installation site. MAGIS
HERCULES PRO is sold with a single code and subsequently,
to facilitate its handling and installation on site, can be separated
into two parts that can be disassembled from each other with
appropriate mechanical and electrical set-ups.
NOTE: It is necessary to check the structural strength of the
oors/ceilings in view of the nal weight of the appliance full

7 SINGLE AUDAX PRO V2 MINIMUM INSTALLATION DISTANCES
Place of installation:
e place of installation is very important and must be estab-
lished by the system's designer or by a specically qualied
person, and must consider the technical requirements, standards
and laws in force.
• e condensing unit must be installed outside the building
only; the indoor unit must be installed inside the building or
outdoors in a partially protected place;
• It is recommended to avoid:
- positioning in basement windows;
- obstacles or barriers that cause recirculation of exhaust air;
- places with aggressive atmospheres;
- limited spaces or anyhow in places where sound levels from
the appliance can be enhanced through reverberations or
resonance;
- positioning in corners where there is an accumulation of
dust, leaves and anything else that can reduce the appliance's
eciency due to blocked passageways;
- prevent exhaust air from the device from coming into the
rooms through doors or windows, thus disturbing people;
• e appliances must:
- be placed on a level surface that is able to withstand its weight;
- be placed on a slab that is hard enough and which does not
transfer any vibrations to the underlying or adjacent rooms;
- installed by means of the vibration-dampening supports sup-
plied with the machine.
• If the unit is installed in zones subject to heavy snow, it will
be necessary to raise the machine by at least the height of the
strongest expected snowfall or, alternatively, use wall-support
brackets (optional).

In addition:
- the unit must be installed in a position protected from snow
falling from above. If this is not possible, you must at least
prevent the snow from clogging the air/coolant exchanger
(even by constructing a small protective roof for the unit, if
necessary);
- the eects of the wind can be minimised by installing the unit
with the intake side facing a wall;
- the unit must not be installed with the intake side against the
wind;
- the eects of the wind can be further minimised by installed
a deector plate facing the unit air ow side (not supplied).
N.B.: The spaces shown must be left free to allow air to
circulate and to ensure accessibility for repairs or maintenance
on every side of the units. In fact, it must be possible to
disassemble all the unit components under the utmost safety
conditions (both for objects and for people).

If the produced condensate is drained through the drain pipe,
connect the standard supplied drain tting (1) in one of the
drainage holes on the bottom of the appliance and close the
other holes with drain plugs (see drawings below) and use the
drain pipe (16 mm internal diameter) commercially available so
that it conveys the water to the desired location. In the event of
installation in very cold zones or zones subject to heavy snow
where the condensate drain pipe can freeze, take the necessary
precautions to keep the drainage holes or the condensate drain
pipe free.
N.B.: If the water produced by the unit is not properly drained,
the performance of the entire system will suer a negative impact
and the system itself could be damaged.
