CLEANING AND MAINTENANCE
Every evening, after use, clean the appliance thoroughly. Daily cleaning after switching off the appliance ensures the
perfect functioning and long life of the appliance.
Before starting to clean the appliance, disconnect the power supply. The steel parts must be washed with hot water
and neutral detergent, then rinsed thoroughly in order to eliminate all traces of detergent. They should then be dried
with a dry cloth. Do not use abrasive or corrosive detergents.
Cleaning the glass
The glass should be washed with vinegar or lemon-based degreasers, suitable for cleaning ceramics and glass.
During this operation, it is best for the glass not to be completely cold, so that spilt food, burnt fat and other
substances can be softened with a damp cloth and removed whilst still warm with a scraper, so as to prevent the
glass surface from deteriorating.
Do not use abrasive or corrosive detergents.
Important: As well as ordinary cleaning and maintenance, it is advisable to have the installation checked by an
installer at least once a year. It is therefore suggested to draw up an after-sales assistance contract.
Cleaning burnished brass surfaces
No synthetic protective varnishes have been used to obtain the special burnishing effect on the burnished brass
be cleaned with any kitchen degreasing detergent, accompanied by the use of an abrasive scouring pad (the
green colored type used for washing dishes). It is recommended that the metal be rubbed, uniformly applying light
pressure, until the desired effect is achieved.
The brass details should then be dried.
that is not compliant with our products. Any spots that may appear over time on the burnished brass surfaces should
be considered as a desirable and particular characteristic of our craft metal working processes.
No synthetic varnishes have been used to obtain the special polish on the chromium-plated brass details in order to
