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.

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.

in the event of prolonged inactivity. Drain as described in the appropriate
chapter.

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.

suggested use the battery kit made by the manufacturer. Carefully observe
the polarity when fitting. At the end of their life, dispose of batteries in
accordance with applicable legislation using dedicated containers.
