4.2 Air connection

Please bear in mind that using air from heated environments may hamper the building thermal performance.
There is one connection for the air intake and one for the air exhaust on the rear side of the appliance. It is important
not to remove or tamper with the two grilles in case of non canalized installation. The outlet air may reach
temperatures that are 5-10 °C lower compared to that of the inlet air and, if not ducted, the temperature of the room of
installation may drop sensibly.
If the water heater is intended to function by externally (or through another room) expelling or intaking the air
processed by the heat pump, pipes specifically designed for the passage of air may be used. Make sure that the pipes
are securely connected and fixed to the product so as to avoid any accidental detachments (for example, use suitable
silicone).
FIGURE 7: Installation examples, with and without canalization, respect the distances indicated.
Figure 8: Inlet/outlet canalization example
WARNING: Do not use outdoor grills resulting in high losses, such as anti-insect grilles.
The grids used should allow good air flow, direct them in order to prevent the cold air being sucked.
Protect pipes from the external wind. The expulsion of air in the chimney is allowed only if the draft is appropriate, is
also required periodic maintenance of the barrel, and chimney accessories.
The total static pressure loss due to installation is calculated by adding the loss of the single installed components;
this sum must be lower than the static pressure of the fan which is equal to (65 Pa).
See diagram on the last page.
WARNING! A type of canalization not suitable affects product performance and significantly
increases the heating time!

Description
Alimentation
WARNING: BEFORE YOU ACCESS THE TERMINALS, ALL SUPPLY CIRCUITS MUST BE DISCONNECTED
The appliance is supplied with a power supply cable (should the latter need to be replaced, use only original spare
parts supplied by the manufacturer).
It is advisable to carry out a check on the electrical system to verify conformity to the regulations in force. Verify that
the electrical system can suitably withstand the water heater's maximum power consumption values (refer to the data
plate), in terms of the size of the cables and their conformity to the regulations in force. It is forbidden to use multiple
outlet sockets, extension cables or adaptors. The earth connection of the appliance is required. It is forbidden to
use piping from the water, heating and gas piping 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. To disconnect the appliance from the mains, use a
bipolar switch complying with all applicable IEC-EN regulations in force (minimum distance between contacts 3 mm,
switch preferably equipped with fuses).
The appliance must comply with the European and national standards, and must be protected by a 30 mA RCD.
Fig. 10 The water heater will always be connected to the power supply network to ensure 24 h operation.
