Electric supply connections
• Cut the electricity supply before any work inside the appliance (risk of electric shock).
• Only a qualified and experienced technician is authorised to carry out cabling work within the
appliance or to replace the power cord.
• Make sure that the terminal screws are fully tightened (risk of fire). Incorrectly tightened terminal
screws will cancel the warranty.
• Do not disconnect the electricity supply when the appliance is running. If the electric power supply is
interrupted, wait a minute before restoring the power.
