and to remove any limescale. In countries which acknowledge EN 1487,
the appliance's water intake pipe must be equipped with a safety device
compliant with said standard; it must be calibrated to a maximum pressure
of 0.7 MPa, including at least a cock, check valve, safety valve and
hydraulic load cut-out.
14. It is normal that water drips from the overpressure safety device or from the
EN 1487 safety unit when the appliance is heating. For this reason one
must install a drain, open to the air, with a continuously downwards sloping
pipe, in an area not subject to subzero temperatures. A condensate drain
should also be connected to the same pipe with a special coupling.
15. Make sure you drain the appliance when it is out of service in an area
subject to subzero temperatures. Drain as described in the appropriate
chapter.
16. Water heated to over 50°C can cause immediate serious burns if delivered
directly to the taps. Children, disabled persons and the aged are
particularly at risk. We recommend installing a thermostatic mixer valve on
the water delivery line.
17. Do not leave flammable materials in contact with or in the vicinity of the
appliance.
18. The appliance is not equipped with batteries, but if you were to use them
they must be removed and put into a specific container before disposing of
the appliance. The appliance must be disconnected from the power supply
before removing the batteries.
