7.1 Standards and regulations

7.2 Liability

2.1 FIRE

Curtains, cloths, chopping-boards or other wooden objects must be kept a safe

distance from hobs and other heat sources; the same applies to vessels

containing alcohol, solvents or inflammable cleaning agents, etc. The risk of

fire in a kitchen is very high.

Fires usually start in a precise point and can be prevented from spreading if

panic is avoided. Hasty reactions may worsen the situation. Never use water to

extinguish an electrical fire; first disconnect the electrical power supply then

extinguish the fire using suitable materials or fire extinguishers.

2.2 ACCIDENTS

There is also a high risk of personal injury (burns, falls) in a commercial kitchen.

Make sure the handles of pans do not protrude from the hob, and frying pans

and other fryer equipment must not be left unattended at any time. Any oil or

grease spilled on the floor must be cleaned up immediately to prevent

slipping.

2.3 ELECTRICITY

The most serious hazards associated with electricity are those of fire

and electrocution.

Follow the safety instructions below:

• Electrical installations: all installation and maintenance should be

carried out by a qualified electrician in accordance with current safety

standards. The main switch must be easily accessible. Cables, plugs

and sockets must be kept in perfect condition.

• Safety: always turn off the main switch before cleaning or any other

operation on the appliance.

Never pull on a power supply cable to unplug an appliance from a

socket.

Do not attempt to repair a damaged cable with insulating tape or other

means, have the entire cable replaced by qualified personnel.

2.4 GAS

The smell of gas is a sign of a probable leak. In this event, close the main shut-off

valve, open doors and windows, and take care not to cause any sparks or

flames.

If you cannot identify the cause of the leak, call a qualified service engineer.

A high percentage of accidents happen because the gas appliances are not

checked regularly: gas appliances are only safe if they are kept in perfect

working order (see chapter 5).

Essential safety precautions when working with gas appliances

To light a gas burner, first bring the flame near to the burner and then turn on the gas.

It is important that the gas burns properly (blue flame) and that there are no restrictions in

the flueways, as these might give rise to dangerous emissions of carbon monoxide

fumes (which are even more hazardous than mains gas, because they are odourless

and give poisoning symptoms that may be confused with harmless disorders).

We strongly recommend the installation of electronic sensors by qualified personnel.

- 2 -

2. HAZARDS IN THE WORK ENVIRONMENT

Adhere scrupulously to the instructions in Section B and do not tamper with the appliance's

safety devices, as this would invalidate any warranty and release the manufacturer from all

liability.

The equipment may be utilised only for the specific uses for which it is intended (as indicated

in Section B).

Any other use is deemed improper and thus hazardous.

THE MANUFACTURER ACCEPTS NO LIABILITY FOR ANY DAMAGE, LOSS OR INJURY

DERIVING FROM INCORRECT INSTALLATION OR USE AND IN THIS CASE DOES NOT

GUARANTEE THE CORRECT OPERATING OF THE APPLIANCE.

3.1 WORKING IN SAFETY

Not to know or to underestimate the risks deriving from the incorrect or improper use of the

appliance can be very dangerous. It is important to adopt working habits in the daily use of the

appliances:

learn the correct use of the various appliances which comprise the

installation;

after each use, always make sure that all appliances are turned off and

then close the shut-off valve and/or turn off the main switch;

do not use inflammable cleaning agents and do not leave containers with these

substances near the appliance;

the appliance is intended for professional use and must be used by qualified

personnel only!

check the correct operation of the appliance every 6 months. On type B appliances, the

fume exhaust duct must also be checked.

Inexperience, negligence or haste may cause situations of emergency which otherwise could

have been avoided. Prevention is the first rule for working in safety. Ensure that the electrical

system is perfect order and that gas appliances are inspected regularly. Always think beforehand

of what you are about to do and how to do it, and act in such a way as to ensure your own safety

and that of your colleagues.

3.2 WHAT TO DO IN THE EVENT OF A MALFUNCTION

Do not attempt any repairs yourself. Turn off the main switch, gas shut-off valves,

water taps, etc. as applicable, and call a qualified service engineer.

We strongly recommend that you contact our Service Centre in your area, which

can provide the necessary expertise and equipment, and which maintains a stock

of original replacement parts.

3.3 PROLONGED PERIODS OF NON-USE

If the appliance is not to be used for a prolonged period, close the gas shut-off valve and/or turn

off the main switch. Clean the appliance thoroughly as indicated in Section B, and protect it

from dust with a cover allowing free air circulation.

3.4 DEFINITIVE DEACTIVATION OF THE EQUIPMENT

Seek assistance from qualified personnel.
