Heat pump water heater – INSTALLATION

4.10 Hydraulic connections

Connect the water heater inlet and outlet to pipes or pipe fittings that can withstand the operating pressure and

temperature of the hot water, which may reach 75 °C. It is not advisable to use materials that cannot withstand such

temperatures. The dielectric union fitting (supplied with the product) must be applied to the hot water outlet

pipe, prior to performing the connection.

Screw a “T” fitting identified by a blue collar onto the appliance’s water inlet pipe.

It is mandatory to fit a safety valve onto the appliance’s water inlet pipe. The device

must comply with the EN 1487:2002 standard and must have a maximum pressure of

0.7 Mpa (7 bar). Moreover, it must at least include the following components: a cut-

off valve, a non-return valve, a control mechanism for the non-return valve, a safety

valve and a water pressure shut-off device.

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

lower side of the water heater.

The appliance must not operate with water hardness levels below 12 °F; on the other hand, it is advisable to use a

suitably calibrated and monitored water softener in the event of particularly hard water (>25 °F); 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.

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.

WARNING: BEFORE YOU GET ACCESS TO TERMINALS, ALL SUPPLY CIRCUITS MUST BE DISCONNECTED

The batteries ensure that the product is protected against corrosion, when the appliance is not powered.

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 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 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.
