voltage (if envisaged) must be implemented exclusively by professionally qualified and authorized
personnel. Before using the appliance, carefully clean all surfaces intended to come into contact with
food.
Warning
Installation operations, any conversion to other types of gas and start-up must only be
performed by qualified personnel, in accordance with current regulations.
Gas systems, electrical connections and premises where the appliances are installed must comply with
current regulations in the country of installation; in particular, the appliance must be installed in a room with
good ventilation, if possible under a suction hood to ensure complete evacuation of the exhaust gases
formed during combustion. The air required for combustion is 2 m3/h per kW of installed power. The
appliance can be installed alone or in series with other appliances in our production range. A minimum
distance of 10 cm between appliances must be respected to prevent contact with any walls made of
flammable material; furthermore, appropriate measures should also be adopted to ensure the thermal
insulation of flammable parts, such as the installation of heat shields; take special care to ensure that
appliances are installed in an appropriate and safe manner. The support feet can be adjustable in height and
any unevenness can therefore be eliminated.
ELECTRICAL CONNECTION
Caution
In accordance with international provisions, when connecting the appliance an automatic
device must be installed up-line of it so that the device can be fully disconnected from the
mains; this device must have a contact aperture of at least 3 mm.
The connection terminal is located behind the rear wall. Proceed as follows to install the power supply cable:
· Remove the rear panel.
· Pass the new connection cable through the cable gland, connect the leads to the corresponding terminal
on the terminal block and fasten them securely.
· Lock the cable with the cable gland and refit the panel. The earth/ground lead must be longer than the
others so that if the cable gland breaks it is disconnected after the power cables.
Note
Make sure that the mains voltage complies with the data on the appliance's ID plate and that there is
good conductivity to earth/ground. Pay attention when inserting leads to ensure they do not obstruct
the normal course of work and routine appliance cleaning operations. Also make sure that the power
cable is never pulled taut and is not placed in contact with sources of heat.

CLEANING
6 CLEANING
6.1 Routine cleaning
Caution
The use of flammable fluids to clean the appliance is forbidden
To ensure hygiene and the durability of the appliance, perform external cleaning on a regular basis, taking
care not to damage the cables and the electrical connections. Before starting cleaning, disconnect the
appliance from the power supply. Parts in steel can be washed with warm water and a neutral detergent:
Rinse them thoroughly to eliminate all traces of detergent and then dry with a dry cloth. Do not use abrasive
and corrosive detergents. Enamelled parts must be washed with soapy water. For appliances that included
an oven, cleaning it is made easier by removing the support grid. Thorough, daily cleaning prevents faults
and accumulated deposits of fat and/or food. The steels used in the manufacture of professional equipment
are tried and tested materials of the highest quality. Thanks to their characteristics, they are ideal materials
for use with food substances.
Consequently, when using stainless steel appliances, the following suggestions must be observed:
· Stainless steel surfaces must always be kept clean, also ensuring contact with the air. The lack of oxygen
under layers of scale, starch, egg white or other deposits means that surfaces can be affected by
corrosion
· Do not use products containing salt or sulphuric acid to remove scale. Suitable products are available
commercially but a diluted solution of acetic acid can also be used
· To clean STAINLESS STEEL appliances, it is advisable to use detergents specifically formulated for this
material. For "minor cleaning", a mild washing up liquid solution may also be used
· Do not wash the appliance with jets of water under pressure
· Avoid using detergents containing abrasive powders or bleaches of any kind
· Lockable stainless steel appliances, during periods of inactivity, must be left uncovered so that air can
freely access internal metal surfaces
· Stainless steel must not remain in contact for long periods with concentrated acids or with aromatised
concentrates such as salt solutions, mustard, spice mixtures or the like. At certain temperatures and
concentrations, these substances can damage the passive layer. Contact surfaces must therefore be
immediately rinsed with clean water and then dried
· It is inadvisable to use stainless steel pots exclusively to cook foods in salt water (pasta, rice, potatoes,
etc.). From time to time, these pots must also be used to cook foods containing fats or vegetables. This
helps to prevent damage caused by corrosion
· After cooking foods in salt water, rinse the tanks with fresh water since salt water residues from cooking
form layers of highly concentrated saline solution that can cause spotting corrosion
· To prevent so-called secondary corrosion, prolonged contact of stainless steel with ferritic steels should
be avoided
· Any secondary corrosion spots must be eliminated immediately
· Do not use sharp objects that may scratch stainless steel parts and consequently give rise to
deterioration
