The user is required to have a suitable recipient for emptying the oil. This recipient must be made of
heat-resistant material and must ensure that, during the emptying stage, the oil does not overflow and does
not represent a hazard. We recommend filtering the oil every day at the end of work and changing it when
necessary. Turn the oil drain cock into the horizontal position. Take special care if the oil is hot.
Caution
Emptying must be carried out when the oil is cold, by inserting an oil drain extension supplied
with the unit, fig. A pos.5 and fig. B pos.6, only after the oil collection container of sufficient
capacity has been positioned. The oil container can be supplied on request.

Replacing parts must exclusively be performed by authorised and/or qualified personnel. When replacing the
electrical components of the machine and the electrical panels, scrupulously follow the technical
characteristics for the replacement component indicated on the component itself. The appliance does not
require any special maintenance but during the use of the equipment it is advisable to check the following at
least once a year (possibly increasing the frequency depending on the degree of use):
· The status of connections especially on the terminal board and the power supply cable, as well as the
· The operating condition of the various components (perform a functional test);
· For appliances fitted with rotary resistances, remove the hub, grease it and replace the three o-ring seals

status of the gas connections;
to avoid possible leaks.
8.2 Replacing the main burner nozzle
· Remove the front screws fastening the dashboard/panel and pull it outwards
· Detach the starter cable
· Unscrew the nut and lower the air adjustment bracket
· Using a suitable wrench, unscrew the nozzle and replace it with an appropriate new one
· Refit the air adjustment bracket in its initial position. Pay attention since the height of the bracket depends
on the type of gas used (see technical data table)
8.3 Replacing the pilot burner nozzle
The pilot burner flame has a fixed air supply. The only necessary item is replacement of the nozzle
depending on the type of gas used (see technical data table).
· Unscrew the coupling connecting the pilot tube to the pilot itself and slide out the nozzle to be replaced

MAINTENANCE
· Replace the nozzle with the appropriate version and make sure that, after ignition, the flame correctly
touches the tip of the thermocouple
Warning
After conversion to another type of gas, update the technical data plate to indicate the type of
gas for which the appliance has been converted.
8.4 Spare parts
It is possible to replace parts such as the valve, the piezoelectric or the ignition control unit (depending on
the type of appliance) or the gas pipes easily and quickly.
To replace such parts, proceed as follows:
· VALVE (fig.B pos.8 and fig.A pos.1); for mobile fryers (fitted with NOVA gas valve and single-phase
adjustment thermostat), after having removed the dashboard and/or front panel, unscrew the screw
couplings of the gas pipes and disconnect the valve's electrical connections. For Top units and Clean
Tank Appliances (fitted with a Eurosit valve), unscrew the screw fittings of the gas pipes and remove the
valve bulb. Then replace the damaged parts and install the new ones.
· THERMOCOUPLE (fig.D pos.3); unscrew the pilot burner coupling, unscrew the valve coupling in the
same way and replace the element
· IGNITION SPARK PLUG (fig.D pos.4); unscrew the coupling, remove and replace the damaged part.
Caution
WHAT TO DO IN THE EVENT OF FAULTS:
Close the gas connection cock and/or switch off the power using the up-line device. Notify
customer service.
Warning
MEASURES TO BE TAKEN IF THE APPLIANCE IS NOT TO BE USED FOR A LONG TIME:

CLEANING
9 CLEANING
9.1 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
