13. Do not tamper with the overpressure safety device, if supplied
together with the appliance; trip it from time to time to ensure
that it is not jammed and to remove any scale deposits. In
countries which have enacted EN 1487, the appliance's intake
pipe must be equipped with a safety device compliant with the
said standard, calibrated to a maximum pressure of 0.7 MPa,
including at least a cock, check valve, safety valve and hydraulic
load cutout.
14. It is normal that water drip from the overpressure safety device
and 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. Make sure to drain the appliance when it is out
of service or in an area subject to subzero temperatures.
15. Make sure to drain the appliance when it is out of service or in
an area subject to subzero temperatures.
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, marked with
a red collar.
17. Do not leave flammable materials in contact with or in the vicinity
of the appliance.
