3.5 Cooking top operating principle
3.5.1 Ceramic glass
The heating elements installed under the ceramic glass top heat the surface to the required
temperature, and a max. of 550 °C can be reached in just a few minutes.
The pot absorbs the heat by means of contact and radiance.
When cooking food, energy saving depends on the quality of the pots and, in particular,
their bottoms.
The pot diameter must match that of the cooking zone. Use pots suitable for electric hot-
plates.

4.1 Before use
If the glass breaks, the appliance cannot be used due to the risk of electric shocks.
4.1.1 Preparazione al funzionamento
Remove all packaging materials and adhesive films very carefully. Remove the protective
film from the panels, ensuring no traces of glue are left on the steel surface; if necessary,
use a non-flammable solvent to remove the glue.
Before cooking for the first time, it is advisable to carefully clean the appliance, and in
particular the ceramic glass top, using hot water and a sponge.
To clean the stainless steel parts, ensure the detergent is non-abrasive and suitable for use
with stainless steel.
After cleaning the appliance, rinse it well with clean water and wipe it dry with a clean
cloth.
Never use a water jet to clean the appliance!

4.2 Using the appliance
4.2.1 Switching on the cooking top
Vetroceramica
Turning the knob (pos. 1 in Fig. 2) to thedesired position switches on the power indicator
light (pos. 2 in Fig. 2) . This means that the appliance is on and the selected cooking zone
is beginning to heat up. This type of heating takes place when the heating elements are
enabled and heat spreads through radiation.The heating elements temperature can be ad-
justed through a power regulator.

2. Minimum temperature
3. Maximum temperature
4. Switching on the second heating element
By turning the knob further, for a few seconds, until it reaches (pos. 4 in Fig. 3), the se-
lected zone reaches maximum heat thanks to the second heating element switching on.
To bring the appliance back to its normal operating status -with only one heating element
switchedon-,turn theknob to the 0 position;if additionalheat is needed, select the desired
temperature.

4.2.2 Cooking
• Select the cooking temperature by means of the energy regulator.
• When cooking food, energy saving depends on the quality of the pots and, in par-
ticular, their bottoms.
• The pot diameter must match that of the cooking zone. Use pots suitable for elec-
tric hot-plates.
• During cooking always use the lid.
• Use the maximum temperature to reach the cooking temperature, then lower it
enough to continue cooking.
Never leave the appliance unattended when switched on!
In daily use, only use perfectly dry pots. Do not place wet containers or objects with con-
densate, e.g. lids, on the ceramic glass top.
4.2.3 Switching off
Switch the cooker off by turning the knob to position 0; the green light also goes off.
The cooking hob may still be red hot! In any case, the appliance has another warning light
indicating any residual heat present on each cooking zone.

4.2.4 Lighting the electrical oven
Choose the heating direction on the knob indicated as (pos. 3 in Fig. 6). Set the cooking
chamber temperature by turning the oven operating thermostat knob in clockwise direc-
tion (from pos. 4b to pos. 4c in Fig. 6), lthe heating elements start to operate and the line
pilot lamp (pos. 2 in Fig. 6) lights up together with the oven indicator lamp (pos. 1 in Fig.
6). When the selected temperature has been reached, the indicator lamp turns off. The
oven temperature can be set between 50° and 300°C and to intermediate values.
A bad smell during the first ignition is considered within the norm and it is due to theover-
heating of the oil residues used for the metal processing and to insulating materials. Dur-
ing the first ignition, without putting food into the chamber, set the oven to a temperature
of 300°C until the smell disappear.

4.3 After having used the appliance
4.3.1 Cleaning
Before cleaning, switch the appliance off and disconnect its power supply.
General information
The main causes for stainless steel wear or corrosion are:
• using abrasive or acid detergents especially chlorine-based products, such as hy-
drochloric acid or sodium hypochlorite (bleach). Therefore, before buying a clean-
ing product, make sure it does not corrode stainless steel (also see paragraph
"Routine cleaning" below);
• ferrous deposits (such as rust dissolved in the water through thepipe system, espe-
cially after a long time without being used), therefore have to be avoided; do not
use wire wool to remove stubborn food deposits. Use, instead, pads or spatulas
made of stainless steel or softer, non-ferrous materials;
• Do not use abrasive steel wool pads to clean the ceramic-glass top; it could get
scratched.
• stagnation of substances having acid components such as vinegar, lemon juice,
sauces, salt, etc. Avoid prolonged contact of the stainless steel parts of the appli-
ance with those substances. The evaporation of saline solutions over the appliance
surfaces is particularly harmful to them.
Routine cleaning
Cleaning the appliance thoroughly on a daily basisis the key to keeping it in perfect work-
ing condition and to prolong its life. Clean the appliance with a damp cloth using water
and soap or detergents, provided that they are not acid or abrasive as discussed above.
Such detergents should not even be used to wash the floor near the appliance, as their
fumes may deposit on the steel surfaces and damage them. If the appliance is very dirty,
use a Scotch-BriteTM type synthetic sponge. Rinse it well with clean water and wipe it
dry with a clean cloth. Do not rub the appliance with steel wool pads as they could leave
rust stains. For the same reason, avoid touching the appliance with ferrous objects.
Never use direct water jets to clean the appliance because this could result in water enter-
ing into it and damaging it.
Do not use abrasive steel wool pads to clean the ceramic-glass top; it could get scratched.
Stains and abrasions on the steel surface
Scratches and dark stains may be smoothed or removed using stainless steel wool pads or
synthetic abrasive sponges, which should always be rubbed in the same direction as the
satin finish.

Rust
If you need to remove rust stains, contact manufacturers of industrial detergents to find a
suitable product. Industrial descaling products can also be used to that end. After remov-
ing stains and rinsing off the appliance with clean water, an alkaline detergent may be re-
quired to neutralize any acid compounds left on the surface.
Cleaning the ceramic glass top
To ensure best use of the appliance, make sure to follow this advice :
• firstly, remove any residual grime and food from the top with a special scraper
(NON-ABRASIVE);
• pour a few drops of suitable detergent on the top when cold and rub with a paper
towel or soft cloth;
• rinse the top and dry with a clean cloth or paper towel;
It is advisable to regularly clean the top whenever it is used.
If aluminium foil, plastic wrap, sugar or foods containing sugar melt on the hob surface
they must be immediately removed from the hot cooking zone with a non-abrasive scrap-
er. This will prevent damage to the surface.
Before cooking foods with high sugar content (e.g. jam) apply a suitable protective prod-
uct on thecooking surface to prevent damaging it in case of spilling from the cooking con-
tainer.
4.3.2 Idle period
If the appliance will be idle for some time, clean it and wipe it dry first, and then apply a
film of a suitable product (such as vaseline oil spray or similar) to protect it. Switch the
power off fitted upstream from the appliance.
In order to prevent corrosion spots from forming, ensure that any salt residues are care-
fully removed from the sides, internally and externally.
4.3.3 Periodic maintenance
Only qualified personnel are allowed to carry out service and maintenance operations.
The following maintenance operations have be carried out at least once a year:
• checking that all control and safety devices operate correctly;
We recommend signing a service agreement providing for at least one check-up a year.
