Dear customer,
Congratulations on your choice and thank you for purchasing one of our appliances. This
practical, modern and functional appliance is manufactured using materials of the highest
quality which are subject to strict quality control checks throughout the entire manufacturing
process. The appliance is meticulously tested to ensure that it meets your demands and
produces perfect cooking results.
Do not remove the appliance from its protective packaging until it is installed in the unit.
Please read these instructions carefully before proceeding to install and use the appliance.
The information contained in these instructions is essential for the correct operation of the
appliance and, more importantly, for your safety.
The packaging of your appliance has been manufactured using only the materials which are
strictly necessary to guarantee efficient protection during transport.
These materials are 100% recyclable, thus reducing the environmental impact. You can also
contribute to caring for the environment, by following the advice below:
- dispose of the packaging in the appropriate recycling bin
- before you get rid of an old appliance, make sure you disable it. Contact your local authority
to find out the address of your nearest recycling centre to dispose of your appliance
- do not pour used oil down the sink. Collect it in a sealed container and take it to an
appropriate collection point or, failing that, place it in the rubbish bin (it will end up in a
controlled dump; this is probably not the best option, but it will avoid contaminating ground
water)
IMPORTANT:
In the unlikely event that the appliance should be damaged or not meet your expectations
in terms of quality, please inform us as soon as possible. For the warranty to be valid, the
appliance must not have been tampered with, or used inappropriately.
