An earthed main socket must be used. Ensure that the building installation has special means for overcurrent and short circuit.

Always disconnect the appliance from the power supply before carrying out maintenance and service work, unless otherwise specified.

Only trained personnel should reach into the control chamber of the machine (accessible from the bottom cover of the machine), with the electrical and electronic parts.
