8. Cleaning & Maintenance
1. Before cleaning, switch off the unit and let it cool down.
2. Carefully clean daily the appliance to guarantee its proper operation and long life.
3. Steel surfaces must be cleaned with a dish washer detergent diluted in very hot water by using a
soft cloth; for the toughest dirt, use ethylic alcohol, acetone or another non-halogenated solvent;
do notuse abrasive powder detergentsor corrosive substances such ashydrochloric acid,muriatic
steel cottons or abrasive disks made with other metals or alloys that might cause rust stains due
to contamination. For the same reason, avoid contact with iron objects. Do not use steel cottons
or stainless steel brushes because whilst they will not contaminate surfaces, they can cause
damaging scratches.
4. Metal powder, metal shavings from working and iron material in general, when in contact with
stainless steel surfaces, can cause rust stains. Superficial rust stain might be present on new
appliances and they can be removed with a detergent diluted in water and a Scotch Brite sponge.
If dirt is tough, do not use sandpaper or rough paper, but use synthetic sponges (for example
Scotchbrite sponges).
5. Do not use substances for cleaning silver and be careful with hydrochloric or sulphuric vapors
coming from floor washing products, for example. Do not aim water jets directly on the appliance,
it might be damaged. After cleaning, rinse properly with clean water and dry carefully with a cloth.
6. The appliances are made in a way that little maintenance is necessary. Despite this, we
recommend that the user subscribes to a maintenance agreement to have the appliance checked
at least once a year by the specialized personnel of our assistance service or by a specialized
technician.
7. Before carrying out any maintenance or repair, disconnect the appliance from the gas
network or cut off the mains. Use only original spare parts supplied by the manufacturer.
8. If the appliance is not used forlong period of time, please clean the equipment and the surrounding
areas properly. Pour a small quantity of cooking oil on the stainless steel surfaces. Carry out all
maintenance operations. Cover all appliances with a suitable material and leave a few openings
to allow air to circulate.
