INSTRUCTION MANUAL
WARNINGS:This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for
their safety.
Children should be supervised to ensure that they do not play with the appliance.
This appliance can be used by children aged from 3 years and above and persons with reduced physical,
sensory or mental capabilities or lack of experience and knowledge if they have been given supervision
or instruction concerning use of the appliance in a safe way and understand the hazards involved.
Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children
without supervision.
Children aged from 3 to 8 years are only allowed to operate the tap connected to the water heater.
CAUTION! Heavy item, handle with care.
1. Models N3 are designed for use at a maximum altitude of 2000m, N1, 3000m.
2. Install the appliance in a room protected from frost (4°C to 5°C minimum). If the appliance is damaged
because the safety device has been blocked, it is not covered by the warranty.
3. Make sure that the wall on which the appliance is mounted can support the weight of the appliance
when filled with water.
4. If the appliance is to be installed in a room or location where the ambient temperature is constantly
above 35°C, ensure that the room is correctly ventilated.
5. When installed in a bathroom, do not install the appliance in volumes V0, V1 of fig. .
6. Position the appliance where it can be accessed.
7. The dimensions of required space for the installation of the device are specified in figure . Installation
of lenticular water heater: To facilitate future replacement of the heating element and replacement of
the anode, leave clear space (300 mm) in front of the cover.
8. Refer to installation figures . Hydraulic connection: follow the figures .
9. If the appliance is set up in a suspended ceiling or attic, or above living space, a drain pan must be
installed underneath the water heater. A drainage device connected to the sewer system is required.
10. A new safety device which conforms to current standards (EN 1487 in Europe), pressure 0.7 or 0.8
MPa (7 or 8 bar) and size ½" in diameter must be fitted the input of the water heater. The safety
valve must be protected from frost (4°C to 5°C minimum).
11. The pressure relief valve drainage device must be activated on a regular basis (every month) in order
to remove limescale deposits and to check that it is not blocked.
12. Connect the safety device to an unpressurised outlet pipe (keep in the openair) in a frost free
environment, with a continuous slope for the evacuation of the water during heating up or draining the
water heater.
13. The circuit working pressure must not exceed 1 MPa (10 bar), its temperature must not exceed 100°C.
14. If PER pipes are used, the installation of a thermostatic regulator on the output pipe of the device is
strongly recommended. It will be set according to the performance of the material used.
15. A pressure reducer (not supplied) is required if the supply pressure is greater than 0.5 MPa (5 bar)
and will be installed on the main supply pipe.
16. This water heater is fitted with a thermostat with an operating temperature of more than 60°C at its
maximum position, capable of reducing the growth of legionella bacteria in the tank. Caution! Above
50°C, water could cause immediate burns. Check the water temperature before taking a bath or
shower
17. DRAIN: Turn off the power and cold-water supply, open the hot water taps then operate the drainage
valve of the safety device NOTE: For water heaters under sinks, disconnect the hydraulic unit and turn
it upside down to drain.
18. Be sure to turn off the power before removing the cover, to prevent any risk of injury or electric shock.
For electric connection, refer to figures  depending on the model. Before removing the cover,
switch off the power.
19. Connecting the heating element directly to the network is prohibited.
20. Upstream of the appliance, the electrical installation must have an bipolar cut-out device
(circuit-breaker, fuse) compliant with the local installation rules in force (30 mA residual current device).
