ELECTRIC INSTALLATION
All storage water heaters are of 230V AC. Before connecting make sure that the mains supply and unit input features
coincide.
The heater's installation procedure is totally straightforward and only requires that Low Voltage Electronic Regulations be
met.
For installations in bathrooms and toilets Regulation IEC 60364-7-701 shall be adhered to.
VOLUME OF PROHIBITION: Zone 1 defined in figure 3.
No switches, sockets or lighting fixtures will be installed.
VOLUME OF PROTECTION: Zone 2 defined in figure 3.
No switches will be installed, however safety sockets or sockets
protected by a 30 mA circuit breaker may be installed.
The boiler should be installed outside the VOLUME OF PROHIBI-
TION, in order to prevent water reaching the inside of the applian-
ce. If the boiler has no plug, electrical power should be supplied
through a bipolar switch with contact openings of at least 3 mm.
The installation should be protected with fuses of a calibre
corresponding to the absorbed current. An earth connection
should be included in every electrical installation. To make this
connection, the boiler plug is provided with the appropriate
contact, therefore it is enough for the base of the plug to
correspond to that supplied with the appliance.
If there is no regulatory "EARTH", we recommend the installation
of a ≤30 mA differential switch.
This appliance complies with the regulation on Radio-electric Disruption and interferences.
WARNING: always service the appliance with official aftersales, included the plug.

START UP
Filling up. Open the shutoff cock as soon as the heater has been installed. Open the hot water taps. Water appears as
soon as the unit fills up completely. Close the taps and check the system for leaks.
Don't connect the heater to the power mains if uncertain as to whether it is full or not.
Electric connection: Plug into the main socket and switch on the main power switch so that the appliance is powered.
After switching on the main power switch, press button (1) to switch on the display (4) that indicates the water heater
temperature. When a certain quantity of hot water is used, the thermostat connects the heating element again.
Temperature selection: Using buttons (2) to decrease the temperature and (3) to increase the temperature, select the
required temperature shown on the display (4). The temperature range is 30 eC to 80 eC. LED (6) and (7) indicate that
the electric resistors are on.
