Heat pump water heater - TECHNICAL INFORMATION FOR INSTALLERS
The device's relief outlet must be connected to a relief pipe with a diameter no less than that of the appliance's
connection (3/4"), with the aid of a siphon creating an air gap of at least 20 mm to allow for visual inspection; this is to
prevent any harm to persons and animals or damage to objects should the device activate and for which the
manufacturer shall not be held liable. Use a flexible pipe to connect the pressure safety device inlet to the cold water
system pipe, using a cut-off valve if necessary. Additionally, a water discharge pipe must be fitted to the outlet in case
the drainage tap is opened.
Avoid overtightening the pressure safety device and do not tamper with it. It is normal for water to trickle from the
pressure safety device during the heating phase; for this reason, it is necessary to connect the outlet, which must always
be left exposed to the atmosphere, to a drainage pipe that slopes downwards and towards an area not subject to frost.
It is advisable to also connect the condensate outlet to the same pipe, through the connection located on the back side
of the water heater.
The appliance must not operate with water hardness levels below 12°F; on the other hand (>25°F), it is advisable to
use a suitably calibrated and monitored water softener in the event of particularly hard water; in this event, the residual
hardness must not fall below 15°F.
If the mains pressure is close to the calibrated valve values, a pressure reducer must be installed as far as possible
from the appliance.
The SYS version is provided with a connection G3/4" for recirculation circuit (if present in hydraulic circuit).
WARNING! It is advisable to carefully wash the system's pipes in order to remove any residues of screw thread,
welding or dirt which may hamper the correct operation of the appliance.

4.5 Electrical connections

Permanent power supply (cable supplied with the appliance)
EDF signal (cable not supplied with the appliance)
WARNING: BEFORE YOU GET ACCESS TO TERMINALS, ALL SUPPLY CIRCUITS MUST BE
The batteries ensure that the product is protected against corrosion, when the appliance is not powered.
Is forbidden remove covers and do maintenance and / or electrical connections by unqualified personnel
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. 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. To disconnect the appliance from the mains, use a
bipolar switch complying with all applicable CEI-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 30mA RCD.
