We hope that it meets your expectations and may offer you optimal service coupled with maximum energy saving for many years to come. [. . . ] 68 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). 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. 5 Electrical connections Cable Permanent power supply (cable supplied with the appliance) EDF signal (cable not supplied with the appliance) 3G 1. 75mm2 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. WARNING: 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. 69 Heat pump water heater - TECHNICAL INFORMATION FOR INSTALLERS PERMANENT ELECTRICAL CONNECTION Use this configuration whenever users do not have a two-tier electricity rate. [. . . ] Set a parameter for lower temperature or a longer unit of “Time W". High level of scaling of the boiler and components Probe error Air temperature out of range Reduced functioning of the heat pump, semipermanent operation of the electrical resistance “Time W” value too low Installation done not in accordance with electric voltage (too low) Evaporator clogged or frozen Problems with the heat pump circuit Insufficient flow of hot water Overflowing water by the the safety valve Are not yet past 8 days by: -First Time instalation. Verify that there are no leaks along the circuit, check Leaks or obstructions by the water circuit the integrity of the the deflector pipe, the integrity of incoming cold water pipe and hot water pipe. If you want to avoid the drip, install an expansion vessel on the plant supply. [. . . ]
