9. If the appliance is equipped with a power supply cable, always contact an
authorised technical assistance centre or qualified personnel whenever
it needs to be replaced.
10. It is mandatory to fit a regulatory safety valve onto the appliance's water
inlet pipe. For countries that have implemented standard EN 1487, the
safety unit must have a maximum pressure of 0.7 MPa and must include
at least a shut-off valve, a check valve, a safety valve and a water
pressure shut-off device.
11. The pressure safety device (safety valve or unit) must not be tampered
with and must be operated regularly to verify that it is not clogged and
to remove any limescale deposits.
12. It is normal for the pressure safety device to drip when water is being
heated. For this reason, the drain outlet must be connected and always
left open to the atmosphere, with a continuously downward-sloping
drainage pipe installed in a location not subject to icy conditions.
13. The appliance must be drained and disconnected from the mains if it is
to be left inactive in a room subject to frost.
14. Hot water running from taps at temperatures above 50°C may immediately
cause serious burns.
Children, the disabled and the elderly run a greater risk in this regard.
It is therefore advisable to use a thermostatic mixing valve connected
to the appliance's water outlet pipe (which is identified by a red collar).
15. No flammable items should be left in contact with or in the vicinity of the
appliance.
16. Do not stand under the appliance or place anything under it that may be
damaged by water leaks, for instance.
17. In the water heater with the HOME+ and/or External Contacts and/or Ener-
gy Flexibility functions active, the water temperature may reach 80°C. Hot
water delivered to the taps at temperatures above 50°C may immediately
cause serious burns. Always check the temperature before using it.
We recommend using a thermostatic mixing valve.
