INSTALLATION AND CONNECTIONS

6.1  Preparation of place of installation

The product must be installed in a suitable place, i.e. to allow normal use and adjustment operations as well as routine and extraordinary maintenance.

The necessary operating space must therefore be prepared by referring to the dimensions given in fig. 9.

The room must also be:

• Equipped with adequate water and electricity supply lines;
• Prearranged for the condensation water discharge connection;
• Prearranged with adequate water drains in case of boiler damage or safety valve intervention or the breakage of pipes/connections;
• Equipped with possible containment systems in case of serious water leakage;
• Sufficiently illuminated (where required);
• Not less than 20 m3 in volume;
• Protected against frost and be dry.
  ATTENTION! To avoid the propagation of mechanical vibrations, do not install the equipment on floors with wooden beams (e.g. in the attic).

6.2 Securing to the floor
To secure the product to the floor, fasten the supplied brackets as shown in fig. 10.

Then secure the unit to the floor with the aid of suitable plugs, not supplied, as shown in fig. 11.

6.3 Aeraulic connections
In addition to the spaces indicated in “6.1 Preparation of place of installation” on page 90, the heat pump.requires adequate air ventilation.
Create a dedicated air channel as indicated in fig. 12.

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.
  The table gives the characteristic data of commercial ducting components with reference to nominal air flows and diameters 160 mm.

During operation, the heat pump tends to lower the room temperature if the air ducting is not to the outside.
A suitable protection grille must be installed at the air extraction pipe to the outside to prevent any foreign bodies from entering inside the equipment.
To ensure maximum product performance, the grille must e 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, generally 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).

6.4 Securing and connections of this appliance
The product must be installed on a stable, flat floor that is not subject to vibrations.
6.5 Hydraulic connections
Connect the cold water supply line and the outlet line to the appropriate connection points (fig. 15).
The table below gives the characteristics of the connection points.

The following figures (fig. 16 – fig. 17 – fig. 18) illustrate 3 examples of hydraulic connection.

Legend (fig. 16 – fig. 17 – fig. 18)

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 insulating casing and comes out at the side of the equipment.
It must be connected, via a trap, to a duct so that the condensate 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 regulations in force and that the electrical system can suitably withstand 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 mA differential 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 appliance’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 (THE TWO W IRES, WH ITEAND BROWN, OF THE 6-CO RE 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 If there is a voltage-free contact, e.g. from the in­verter, 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 prefer­ential 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 in AUTO mode.

6.6.1.1 Remote connection
For the connection to the digital inputs the equipment is sup­plied 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.

To access the 6-core cable for remote connection, remove the upper cover of the boiler and run to the outside the cable, already present inside the unit, through the special cable gland installed in the back cover.
