2. SAFETY REGULATIONS
The electric supply connection shall be made by a qualified electrician and comply with IEC
60364-1.
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 two safety valves, able to ensure the safety
of the machine itself in case other primary control devices are inefficient (due to a fault). Due
to the extreme importance of these components and as not to compromise the safety of the
machine, it is recommended to provide to check them and to substitute them through an
authorized service center by 1.500 hours of usage or once a year, 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 leak 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 internal pressure.
It is recommended not to
use the machine, immediately unplug the machine from the power feeding and call the
service center.
MUD DRAIN FROM THE BOILER
If you are not acquainted with the hardness level of the
used water, it is recommended to proceed with the boiler cleaning (according to the
