Install each air channel, making sure:
• It does not weigh down on the equipment.
• It allows maintenance operations.
• It is adequately protected to prevent the accidental intrusion
of materials inside the equipment.
• The connection to the outside must be done with suitable,
non-flammable piping.
• The total equivalent length of the extraction pipes plus the
delivery, including grilles, must not exceed 12 m.

During operation, the heat pump tends to lower the room tem-
perature if the air ducting is not to the outside.
A suitable protection grille must be installed at the air extrac-
tion pipe to the outside to prevent any foreign bodies from
entering inside the equipment. To ensure maximum product
performance, the grille must be selected from those with low
pressure loss.
To avoid the formation of condensation water: insulate the air
extraction pipes and the ducted air cover connections with a
steam-tight thermal covering of adequate thickness.
Install silencers if deemed necessary to prevent noise due to
the flow. Equip the pipes, wall outlets and connections to the
heat pump with vibration-damping systems.
6.3.1 Special installation
One of the peculiarities of the heat pump heating systems is
that these units considerably lower the air temperature, gen-
erally expelled to the outside of the house. As well as being
colder than the ambient air, the expelled air is also completely
dehumidified, therefore the air flow can be returned inside for
the summer cooling of specific rooms or areas.
Installation provides for splitting of the extraction pipe, which is
fitted with two dampers ("A" and "B") for directing the air flow to
the outside (fig. 14) or the inside of the house (fig. 13).

6.5.1 Condensate drain connection
The condensate forming during heat pump operation flows
through a special drain pipe (1/2"G) that passes inside the insu-
lating casing and comes out at the side of the equipment.
It must be connected, via a trap, to a duct so that the conden-
sate can flow regularly (fig. 19).

6.6 Electrical connections
Before connect the appliance to AC mains, a check must be
carry out on the electrical system to verify conformity to the reg-
ulations in force and that the electrical system can suitably with-
stand the water heater’s maximum power consumption values
(refer paragraph 3.2 for to technical characteristics), in terms of
the size of the cables and their conformity to the regulations in
force.
The appliance is supplied with a power cord with a Schuko plug
(fig. 21) and for the connection with AC mains is required:
• a Schuko wall socket with ground and separate protection is
required (fig. 20);
• an omnipolar 16 A circuit breaker with a contact opening of
at least 3 mm;
• a 30 mAdifferential circuit breaker.
It is forbidden to use multiple outlet sockets, extension cables
or adaptors.
It is forbidden to use piping from the water, heating and gas
systems for earthing the appliance.
Prior to operating the machine, make sure that the electricity
mains voltage conforms to the value indicated on the appli-
ance’s data plate.
The manufacturer of the appliance shall not be held liable for
any damage caused by failure to earth the system or due to
anomalies in the electric power supply..

6.6.1 Remote connections
The equipment is prearranged to be connected to other remote
energy systems or energy meters (solar thermal, photovoltaic,
Off-Peak)
INPUTS
• Digital 1 (DIG1). NOT USABLE
(THETWOWIRES,WHITEANDBROWN,OFTHE6-CORE
CABLE ARE NOT TO BE USED)
• Digital 2 (DIG2). Digital input for photovoltaic. In case of a
photovoltaic system connected to the plant, it can be used
to subtract energy in the form of hot water in times of over-
production. If there is a voltage-free contact, e.g. from the in-
verter, which closes when there is overproduction of energy,
it can be connected to the two green and yellow wires of the
6-core cable supplied with the.equipment.
Set the parameter P23 = 1 to activate the supplement with
photovoltaic.
• Digital 3 (DIG3). Input for Off-Peak. This function, available
only in some countries, allows the equipment to be activated
only when there is a signal coming from outside with prefer-
ential tariff. If the electric contactor has a voltage-free contact
which closes when the preferential tariff is available, it can be
connected to the two gray and pink wires of the 6-core cable
supplied with the equipment.
Set the parameter P24 = 1 to activate Off-peak in ECO mode
or P24 = 2 for Off-peak inAUTO mode.
6.6.1.1 Remote connection
For the connection to the digital inputs the equipment is sup-
plied with an additional 6-core cable already connected to the
PCBA (located inside the device). The remote connections to
possible energy systems are the responsibility of the qualified
installer (connection boxes, terminals and connection cables).
The following figures give an example of remote connection (fig.
22 and fig. 23) which must not be longer than 3 m.
