SAFETY REGULATIONS
§ It is recommended not to open or remove any machine part for any reason; in case the unit should
present an abnormal functioning or a failure, disconnect the power plug and contact an authorized
service center or the dealer where the product has been purchased.
§ If the power cable is damaged, it has to be replaced by the manufacturer or by an authorized
technical service or by a qualified person in order to prevent any risk.
§ It is recommended that the electric supply to this machine should include either a residual current
device that will interrupt the supply if the leakage current to earth exceeds 30ma for 30ms or a device
which will prove the earth circuit.
§ SAFETY VALVE This machine is equipped with one safety valve, able to ensure the safety of the
machine itself in case other primary control devices are inefficient (due to a failure). Due to the
extreme importance of this component and as not to compromise the safety of the machine, it is
recommended to provide to check the valve and to substitute it through an authorized service center
every 2 years starting from the purchasing date.
§ PRESSURE SWITCH This machine is equipped with a pressure switch able to check and to maintain
the pressure under certain preset limits (ref. “rated pressure” on the technical label underneath the
machine). In case there would be a steam leakage on the lower side of the machine, it means that
the functioning of this device has been compromised and the safety valve has been involved as to
limit the boiler’s internal pressure. It is recommended not to use the machine, immediately
unplug the machine from the power feeding and call the service center.
§ THERMOSTATS. The unit is equipped with 2 thermostats able to control the over temperature. In
case the main control system becomes inefficient, TR1 and TR4 would intervene permanently by
deactivating the boiler heating. If this occurs, disconnect the power plug and contact a service center.
