INSTALLATION
1. PRODUCT FIXATION
See “General Warnings” N°.1 to N°.6
For product installation, refer to drawings section 1 page.2.
2. HYDRAULIC CONNECTION
See “General Warnings” N°.10 to N°.14
For hydraulic connection, refer to drawings section 2 page 3.
- It is necessary to clean the supply piping prior to the hydraulic connection. The connection to the
hot water outlet is to be carried out with a cast iron or steel sleeve or a dielectric connector, to
avoid corrosion of the pipe (direct contact iron / copper). The use of brass fittings is prohibited.
- Always install a new safety device on the cold water pipe of the water heater, which comply with
the standards (EN 1487 in Europe), with a pressure of 7 or 9 bars (0.7 or 0.9 MPa) according to
the nominal pressure, with diameter 1/2".
- CAUTION: Do not use the safety valve included in this packaging in France (home country and
French overseas)
3. ELECTRICAL CONNECTION
For electrical connection, refer to drawings section 3 page 4.
- The water heater can be connected and operated only on AC 230V. Connect the heater with a
rigid cable with conductors 2,5mm ². Use a standardised channeling (rigid or flexible conduit) until
the calibrated housing cover.
- Directly connect devices with a cable or plug. In France, a product with plug is strictly prohibited
and cannot be sold and installed.
- Always connect the earth conductor of the cable to the earth ground wire or connect the earth
conductor to the appropriate terminal identified by the symbol . This connection is compulsory
for safety reasons. The earth wire green - yellow must be longer than those of phases. The
installation must be equipped, upstream of the appliance, with a bipolar cut-out device (minimum
contact distance of 3 mm fuse, breaker switch). In the case where hydraulic connexions are in
insulated material, electrical circuits shall be protected by a differential circuit breaker 30 mA
adapted to local standards.
Thermal circuit breaker (refer to drawings section 5 page 4): All our products are
equipped with a thermostat with thermal circuit breaker and manual resetting which cuts
off the power supply to the water heater in case of overheating. If the safety trips:
switch off the power before taking any further action,
remove the cover,
check the electrical connections,
reset the thermal circuit breaker
If the circuit breaker keeps tripping, replace the thermostat. Never short circuit the safety cut out or
the thermostat. Connect the power supply only via the terminal.

SETUP & OPERATION
- CAUTION: NEVER POWER THE WATER HEATER WITHOUT WATER: Models with an electric
heating element will be certainly damaged.
- Fill the tank completely. Before powering up, open the hot water taps, drain the pipes in order to
empty the air.
- Check the tightness of the tubes and of the flange seal under the plastic cover. In case of leaking
tighten moderately. Check the operating of the hydraulic components and of the safety valve.
- Turn the power on. After 15 to 30 minutes, depending of the capacity of the device, the water
should drip from the drain. This is normal and due to the expansion of water. Check connection
leaks and seal. During heating and according to the water quality, hot water tanks can make a
bubbling noise. This noise is normal and does not indicate any defect of the unit.
The water heater features a digital screen that allows to choose the running mode (see.
drawing section 4 page 4).
1/ MODE selection key (Ref. A): Enables to choose the running mode. Press twice to change the
mode.
2/ Setting arrows keys (Ref. B): In the selected modes, these keys allow to increase or decrease
the setpoint temperature (steps of 1°C).
3/ Indicator of operating mode (Ref. C): Shows the current running mode of the product.
4/ Operating modes (Ref. D)
FROST FREE Mode : Automatic regulation at frost-free temperature (7°C), in order to reduce
the electric consumption during the periods of absence of the user.
SMART Mode : Fully automatic operation of the water heater: after a learning period, the
product will adjust automatically the hot water temperature adapted to the user consumption.
This allows lowering of the electrical consumption.
MINI Mode : User selects a hot water temperature between 45°C and 50°C (default value of
50°C).
CONFORT Mode : User selects a hot water temperature between 50°C and 65°C (default
value of 65°C). Warning: this operating mode might increase the electrical consumption of the
product.
MAX Mode
70°C). Warning: this operating mode increases the electrical consumption and scaling. Using
hot water with high temperature may cause burns. It is strongly recommended to take all the
necessary precaution to use this operating mode.
5/ Temperature display (Ref. F):
In FROST FREE Mode , it indicates the temperature setpoint of 7°C automatically fixed by the
product.
In SMART Mode , the displayed value is the temperature setpoint automatically analysed
and fixed by the product. When a large quantity of hot water is used, the displayed temperature
is the one measured close to the bottom side of the product (30cm for a 50L product, 40cm for
80L and 100L). That means the remaining quantity of hot water is limited (10L of hot water
remaining for a 50L product, 30L remaining for a 80L product and 50L remaining for a 100L
product).
In MINI , CONFORT and MAX modes , i t shows the temperature of water inside the
tank. When pushing the setting keys (Ref. B), the screen displays during a few seconds the
setpoint temperature chosen by the user before displaying again the water temperature inside
the product.
6/ Heating indicator (Ref. E): Shows when the water is under heating. NOTA: if the indicator is on
continuously, that means the product is under heating. It doesn’t reveal a bad running of the
product.
: User selects a hot water temperature between 65°C and 75°C (default value of
