6.1 Safety, cleaning and repair rules
• This appliance is used for the preparation of meals at industri-
al level. Usage and cleaning can be carried only by expert per-
sonnel. Maintenance and repair can be carried out only by
skilled technical personnel.
• These indications must be communicated to all those con-
cerned during internal training.
• Attention! This appliance must be constantly watched over
when being used!
• Grease and overheated oil can catch fire. Use this appliance
only under constant control. Never use water to put out
grease or oil! Cover with a lid, turn off the hot plate and
remove pot from the burner.
• Do not leave the burners running.
• Do not overload the kitchen. For proper use, pots should
not be bigger than the flames.
• Parts of the appliance and attachments exposed to food
must be cleaned with detergents and rinsed thoroughly with
potable water.
• Do not clean the appliance using water jets or steam,
whether direct or pressurized!
• If the room is being cleaned with water/steam jets or high-pres-
sure equipment, it is necessary to switch off the appliance first!
• Before starting to clean the appliance, disconnect from the
mains.
• Do not use inflammable liquid to clean the appliance.
• Repairs may be carried out only by skilled personnel.
• During repairs, the appliance must undergo voltage
omnipolar insulation (local switch, i.e. safety load cut-off
switch).
• Noise emission values of the appliance in operation are below
70dB (A). This value is compulsory according to certain national
safety standards.
WARNING
Attention! The manufacturer declines all responsibility concern-
ing mistakes included in these instructions due to translating or
printing errors: the manufacturer also reserves the right to
change the product as he see fits, though without changing its
essential features. The manufacturer declines all responsibility for
any non-compliance with the provisions contained in this manu-
al.
6.2 Turning the appliance off in case of
breakdown
In case of breakdown, shut down the appliance as instructed in the
paragraph "What to do in case of failure or prolonged period of dis-
use". In case of breakdown, close the connecting cock of the unit.
Disconnect the appliance from the power mains.
6.2.1 What to do in case of failure or prolonged period
of disuse
When the appliance is not to be used for a long time, clean thor-
oughly, close the gas cock and switch off any electric power.
In case of malfunctioning or failure, close the gas cock. In case of
malfunction, call the service centre.

6.3 Appliance care and frequency of maintenance
Thorough daily cleaning of the appliance, after disconnecting it, will
keep it in perfect working order and make it last longer. All steel
parts should be cleaned with water and a detergent, using a damp
cloth; do not use abrasive substances or corroding detergents.
Do not use steel wool, which could cause rust to form.
For the same reason, avoid touching the appliance with anything
made of iron. Do not clean with sandpaper and lubricating gel paper.
If absolutely necessary, you may use pumice powder.
If the appliance is extremely dirty, use a synthetic sponge (i.e.
Scotchbrite sponge).
After cleaning the appliance, rinse with clean water and wipe with
a clean cloth.
If the main burner needs cleaning, proceed as follows:
• Remove the pan support, cover, rings and burner crown;
• Clean burner parts with water, soap and a suitable tool, then
rinse and wipe;
• When reassembling the parts, make sure you place them back in
the right position.
All maintenance and repair work must be carried out by authorized
technicians only.
The appliance must be checked at least once a year. For this reason,
a service agreement contract is recommended.
6.4 Recommendations for the treatment of
stainless steel industrial kitchens
6.4.1 Useful information on stainless steel
Industrial kitchens are generally made of stainless steel having the
following material codes:
• 1.4016 or 1.4511 = magnetizable chromed steels
• 1.4301, 1.4401 and 1.4571 = non-magnetizable chromed steels
Chromed steels have favourable thermo-technical characteristics. In
fact, they have less of a tendency to warp due to the effect of heat.
Chrome-nickel steels, instead, have good corrosion resistance features.
Stainless steel corrosion resistance is given by an inactive coat that
builds up on the surface by coming into contact with oxygen.
The oxygen in the air is already enough to build up the inactive
coat that allows automatic removal of anomalies and damage due
to mechanical actions. The inactive coat builds up or re-builds up
faster if the steel comes in contact with running water containing
oxygen.
A more powerful effect is given by oxidative acids (nitric acid, oxalic
acid). These acids are used if the steel has undergone strong chemi-
cal stresses, hence generally losing its inactive coat.
The inactive layer can be chemically damaged or jeopardized by
reducing agents (oxygen consumption) if they come in contact with
the steel, concentrated or at high temperatures. These active sub-
stances include for instance:
• saline and sulphurous substances
• chlorides (salts)
• concentrated spices such as mustard, vinegar essences, soup
cubes, kitchen salt solutions, etc.
More damage can be caused by:
• outside rust (i.e. from other components, tools or incipient rust)
• iron particles (i.e. file dust)

Attention! When cleaning, carefully avoid washing the
appliance with direct water jets or high-pressure
water!
Cleaning must be performed when the appliance is cold.
Never clean the appliance with water jets or high-pres-
sure water!
