Electric supply connections
•
Cut the electricity supply before any work inside the appliance (risk of electric shock). The removal of the power
supply has to be such that you can always check from any of the points to which you have access that the power
supply remains removed. If this is not possible, you should provide a disconnection with a locking system.
•
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.
