necessary, internally) with products that are more than 90%
biodegradable.
Use lukewarm water, a neutral detergent/cleaner if necessary,
and a soft brush or sponge. If another type of detergent is used,
carefully follow the producer's instructions and observe the
safety rules given in the information sheets provided with the
product or substance.
CAUTION
• Do not use solvent-based detergents
(e. g. trichloro-ethylene) or abrasive
powders for cleaning.
• Do not use steel brushes, steel wool,
copper cloths, sand-based or similar
products for cleaning.
• Only start cleaning once the appliance
has cooled.
• Do not clean the appliance with flam-
mable liquids.
Accessories such as baskets and containers, if present, must
be cleaned outside of the appliance.
WARNING
When using chemicals, comply
with the safety notes and dosage
recommendations printed on the
packaging. Refer to the chapter
A.2 Personal protection equip-
ment
for
products.
L.3
Stainless steel surfaces
The reason stainless steel can resist corrosion and rust is its
passive layer which builds up when oxygen hits the metal
surface. There is sufficient oxygen in the air to do this.
If this passive layer is physically broken or damaged by
chemical substances, leaving it unable to regenerate itself,
even rust-free stainless steel can be subject to corrosion.
It is possible to develop or regenerate the passive layer by
treating it with running, oxygen-rich water.
Oxygen-starving abrasives such as hydrochloric acid, chlor-
ides and spice concentrates, mustard, vinegar essences,
spice cubes and cooking salt solutions can lead to chemical
damage or rupture of the passive layer, depending on the
concentration and temperature.
Extraneous rust (iron particles), the formation of galvanic
elements and lack of oxygen could cause more damage.
IMPORTANT
Keep stainless steel surfaces clean at all times and
make sure they are well ventilated.
Please follow these instructions:
• Remove grime, fat and other cooking residuals from steel
surfaces when cool using soapy water, with or without
detergent, and a cloth or sponge.
Dry the surfaces thoroughly after cleaning.
• In case of encrusted grime, fat or food residuals, go over
with a cloth or sponge, wipe in the direction of the satin
finish and rinse often.
Rubbing in a circular motion combined with the particles of
dirt on the cloth/sponge could spoil the steel's satin finish.
• Metal objects can spoil or damage the steel: damaged
surfaces become dirty more easily and are more subject to
corrosion.
• Restore the satin finish if necessary.
handling
chemical
• Do not let stainless steel parts come into prolonged contact
with acids, spices, salts, etc. Even acid fumes which build
up from cleaning tiled surfaces can promote corrosion.
Rinse off work surfaces with fresh water. This applies
especially after cooking potatoes, pasta or rice in salted
water.
L.4
Daily cleaning
CAUTION
• Do not use a high-pressure cleaner to
clean the floor directly in front of, next to
and behind the appliance.
Control panel
• Clean the control panel with a soft cloth dampened with
water and, if necessary, with neutral detergent.
External surfaces
• Wash the external surfaces with warm, soapy water.
• Avoid using detergents containing abrasive substances,
steel wool, brushes or steel scrapers.
• Rinse with a damp cloth and dry carefully.
• Avoid using chlorine or ammonia-based products.
Tank
• Remove any residuals of food, grime, fat, other cooking
residuals and starch from the tank and baskets using boiled
water on a daily basis adding a degreasing cleaning agent if
necessary.
• Carefully dry the tank and baskets to avoid the stagnation of
liquids.
L.5
Drain tap
If the cooking appliance has a drain tap, this must be cleaned
and grease every day after the last use of the appliance,
depending on the frequency of use:
• dismantle the drain tap unit, refer to the paragraph K.5 Drain
tap;
• clean with a mild cleaning agent;
• dry and grease lightly with a special odourless, tasteless
grease:
We recommend:
– grease for taps and fittings (for taps with seal/O ring) =
code 0S2118.
– lubricant for taps with metal seals (for taps without seal/O
ring) = code 0S2277.
L.6
Descaling
WARNING
Refer to "Personal protection
equipment".
IMPORTANT
Remove limescale, fat, starch and protein layers
with regular cleaning to avoid corrosion.
• Use a solution of 10% vinegar, 10% phosphoric acid or a
suitable de-scaling solution available for purchase.
• Never use steel wool or other abrasive materials which can
scratch the surface of the stainless steel.
WARNING
Make sure no water comes into
contact
